Minor Changes

  • Wrap concatenated modules in lazy __webpack_require__.cw accessors and inline require(), keeping a wrapped body's names and side effects intact. (by @​hai-x in #​21519)

  • Add performance hints reporting what a build costs: duplicate packages and modules, circular dependencies, broad contexts, large modules and chunks, hotspots, eval, missing PURE annotations, polyfills, redundant dynamic imports, OS-dependent rules, cache effectiveness, how chunks load, what splitting refused, why an optimization was skipped, and rules, defines, externals, aliases and barrel reexports nothing uses. An oversized asset names its largest modules, and an entrypoint carrying the runtime recommends optimization.runtimeChunk. Enable every check not set individually with performance.all, report hints in stats only with performance.hints: "stats", and get them in a stable order that leaves the build hashes unchanged. (by @​alexander-akait in #​21841)

  • Add the descriptionRelativePath module rule condition. (by @​alexander-akait in #​21705)

  • Add OS-independent glob matching to module rules. (by @​alexander-akait in #​21771)

  • Report inner-graph, AMD and bare module bailouts in optimizationBailout. (by @​alexander-akait in #​21740)

  • Allow marking externals as side-effect-free with a sideEffects flag. (by @​alexander-akait in #​21712)

  • Give externals the original request of a context module element. (by @​alexander-akait in #​21780)

  • Add the externalsPresets.nodeModules preset with an allowlist option to externalize installed packages, replacing the webpack-node-externals plugin. (by @​alexander-akait in #​21569)

  • Add output.library.umdAmdContainer for an AMD-style loader branch in UMD. (by @​hai-x in #​21770)

  • Resolve @custom-media values that are true / false or name another custom media. (by @​alexander-akait in #​21624)

  • Add the __webpack_css_server_styles__ module variable to read the CSS collected while rendering without a DOM, and keep that CSS in the order the styles were applied. (by @​alexander-akait in #​21576)

  • Patch the HTML <head> in place on hot update instead of forcing a full reload, including when a <script> that never executed is removed. (by @​alexander-akait in #​21624)

  • Scope counter names in CSS modules; fix the counter() counter-style and animation timeline keywords. (by @​alexander-akait in #​21600)

  • Derive import defer / import source from the target and fix the source phase. (by @​alexander-akait in #​21810)

  • Emit analyzable ESM urls for chunks, assets, styles, workers and wasm. (by @​alexander-akait in #​21788)

  • Tree shake CommonJS: module.exports object literals, exports destructured from a require() binding, unused method requires, and unused side-effect-free require() calls and reexports. (by @​alexander-akait in #​21841)

  • Resolve relative entry baseUri values and bake one side of a hash cycle. (by @​alexander-akait in #​21750)

  • Minify CSS further, only where the document is unchanged: shorthands and box longhands, font-weight, <position> and font-stretch keywords, colors (polar, Lab and hsl() converted to hex), numbers, times, zero units, calc() and every math function the spec names folded over constants, selector lists, An+B, keyframe selectors, media-feature ranges, unicode-range, transition layers, display, transforms, gradients, font families, identical repeated declarations, and rules an identical later one makes dead. Abilities are read off the target browsers, vendorPrefixes adds and drops vendor prefixes for them, and rewriteCustomProperties shortens custom property values. Minification never changes whether a declaration parses, and beautifying keeps every rule. (by @​alexander-akait in #​21841)

  • Safely minify CSS (with source maps) and HTML assets when optimization.minimize is enabled, unless a minimizer is already configured for them, making only transformations an engine cannot tell apart. Every rewrite is named as an option, so it can be switched off. (by @​alexander-akait in #​21841)

  • Minify HTML further where the parsed document is unchanged: drop redundant quotes, whitespace nothing renders, escapes text does not need, implied tags, optional end tags nothing prints behind, empty attributes and nested empty elements; fold enumerated values and casing; normalize each attribute against the element it is on; and rewrite style, token lists, srcset, sizes, URL, integer and boolean attributes, viewport content, inline <style> and a JSON <script> body through their own grammars. Adds the optimization.minimize.html options collapseWhitespace, mergeStyles, minifyConditionalComments, minifySrcdoc, preserveComments, removeEmptyAttributes, removeEmptyElements, removeImpliedTags, removeRedundantAttributes, sortAttributes and sortTokenLists, and keeps an end tag the parent, the next element or the adoption agency would otherwise restructure the tree over. (by @​alexander-akait in #​21841)

  • Suggest the closest name or a casing fix anywhere in a failed request. (by @​alexander-akait in #​21727)

  • Add aggregated shutdown hook to MultiCompiler. (by @​bjohansebas in #​21578)

  • Report which compilers changed on the MultiCompiler done hook. (by @​bjohansebas in #​21580)

  • Add [containedpath]/[containedfile] placeholders, used for [path]/[file] of asset and html modules with experiments.futureDefaults. (by @​alexander-akait in #​21592)

  • Support an object for an entry's html that overrides output.html per option. (by @​alexander-akait in #​21574)

  • Configure or exclude each asset type's minifier via optimization.minimize. (by @​alexander-akait in #​21663)

  • Support printing CSS and HTML beautified as well as minified. (by @​alexander-akait in #​21660)

  • Add renderEmbeddedSource, and minify what it offers out of the box. (by @​alexander-akait in #​21830)

  • Report bindings named eval, arguments or reserved words in ES module output. (by @​alexander-akait in #​21567)

  • Emit no development source map for module libraries, or any with futureDefaults. (by @​alexander-akait in #​21839)

  • Speed up builds and cut memory: faster CSS, HTML and JavaScript parsing and minification, a built-in scope analyzer replacing eslint-scope, faster dependency hot paths, module diagnostics, CommonJS export scanning and concatenated module renaming, runtime modules, parsers, generators and dependencies loaded only when used, one file watcher pool shared between MultiCompiler children, and lower parser, graph and startup memory. (by @​alexander-akait in #​21841)

  • Improve tree-shaking for a namespace reexported as default, and fix import d from "./mod"; d.member reading undefined in that case. (by @​alexander-akait in #​21841)

  • Warn on cross-kind CSS module export conflicts and let the class win. (by @​alexander-akait in #​21538)

  • Add output.resourceHints.dedupe to skip prefetch links for already preloaded/prefetched chunks. (by @​alexander-akait in #​21386)

Patch Changes

  • Let a memory-cache etag mismatch fall through to the file cache instead of reporting a miss. (by @​alexander-akait in #​21624)

  • Determine provided exports in dependency order, so a build's module hashes no longer depend on what the persistent cache held. (by @​alexander-akait in #​21630)

  • Emit no dead module and no failing require for an asset-url external. (by @​alexander-akait in #​21713)

  • Fix names, hidden devtools and cache reuse for CSS maps inlined into JS. (by @​alexander-akait in #​21558)

  • Follow the HTML spec more closely when parsing and printing: frameset content, quirks paragraphs and selects, <![CDATA[ outside foreign content as a bogus comment, <?target data?> as a processing instruction, </> dropped, comment data and DOCTYPE identifiers read from the tokenizer states, attributes merged from a repeated <html>/<body> tag, legacy JavaScript script types, void keygen and font format detection — and hand back the tree a parsed document was built from when printing it. (by @​alexander-akait in #​21841)

  • Clear a Watching's blocked flag when its build starts, so it reports only a child actually waiting for its MultiCompiler parent. (by @​bjohansebas in #​21639)

  • Fix AMD define() output using the wrong module and exports argument names. (by @​hai-x in #​21814)

  • Fix ReferenceError from import.meta.main using the wrong module argument. (by @​hai-x in #​21620)

  • Leave a @namespace URI alone instead of resolving and rewriting it as an asset. (by @​alexander-akait in #​21658)

  • Resolve escaped CSS names, and scope a grid area cell name as one name. (by @​alexander-akait in #​21665)

  • Track exports usage of side-effect-free modules an active import() evaluates. (by @​hai-x in #​21623)

  • Resolve absolute symlink targets and treat an unreadable context as missing. (by @​alexander-akait in #​21647)

  • Fix corrupted icon URLs in a .webmanifest with a BOM or non-ASCII text. (by @​alexander-akait in #​21655)

  • Respect strictThisContextOnImports for require() member calls. (by @​hai-x in #​21601)

  • Fix import.meta, [object Object] asset urls and crashes in build-time executed modules. (by @​alexander-akait in #​21841)

  • Inherit sideEffects past a type-only nested package.json for files under node_modules. (by @​xiaoxiaojx in #​21686)

  • Do not fail directory creation when the file system reports it already exists. (by @​alexander-akait in #​21698)

  • Fix top-level using and await using declarations in modules. (by @​alexander-akait in #​21557)

  • Fix DefinePlugin optional chains reading an undefined object member. (by @​lazerg in #​21823)

  • Fix MultiCompiler: compute the common outputPath by whole path segments, run again after a dependency validation failure, and recover watch mode from a fatal child error without leaking watchings. (by @​alexander-akait in #​21841)

  • Keep a nested bundle's runtime tables separate when bundling webpack output. (by @​alexander-akait in #​21568)

  • Keep the runtime out of strict mode when output.globalObject reads this. (by @​alexander-akait in #​21715)

  • Run an even-priority __webpack_require__.O handler without waiting. (by @​alexander-akait in #​21803)

  • Treat top-level this in a classic worker entry as its global scope. (by @​alexander-akait in #​21720)

  • Rehash runtime modules whose code changes under a content-named filename. (by @​alexander-akait in #​21828)

  • Fix namespace object reexports and string export names in module library output and emit a CommonJS entry's default as export default. (by @​alexander-akait in #​21589)

  • Keep tree-shaken JSON arrays as arrays when a prototype property is read. (by @​hai-x in #​21599)

  • Generate every CSS and HTML lookup table into lib/{css,html}/data.js from mdn-data, color-name and the spec IDL — including the value-type facts read out of the CSS value-definition grammars — leaving both syntax.js files algorithm only. (by @​alexander-akait in #​21841)

  • Support UNC paths in module and context replacement plugins. (by @​avivkeller in #​21645)

  • Emit less runtime code: shorter syntax where output.environment allows, no IIFE for a RuntimeModule without locals, no unread __webpack_esm_id__ and exports.id chunk exports, and an ESM entry chunk installing its own modules from its local bindings instead of importing itself. (by @​alexander-akait in #​21841)

  • Release the compilation and file system caches retained after compiler.close(). (by @​alexander-akait in #​21603)

Patch Changes

  • Resolve aliases pointing at a package directory whose name ends with .js again. (by @​alexander-akait in #​21542)

  • Name CSS sources in source maps by their resource path, without the css prefix. (by @​bjohansebas in #​21536)

  • Delete no longer referenced files from the filesystem cache directory after storing the cache, age them by recorded time so restored caches are cleaned too, and collect every fully expired pack in one store instead of one per build. (by @​bjohansebas in #​21528)

  • Make require(esm) module.exports re-export analysis independent of module processing order. (by @​alexander-akait in #​21521)

  • Ignore ERR_SERVER_NOT_RUNNING on lazy-compilation backend dispose so compiler.close() succeeds on Bun. (by @​alexander-akait in #​21521)

  • Name the failing key when DefinePlugin fails to evaluate a typeof value. (by @​alexander-akait in #​21503)

  • Improve Deno compatibility: guard setNoDelay and force-close connections on lazy-compilation backend dispose, and return a real ArrayBuffer from the Node async/sync wasm loader so WebAssembly.instantiate accepts it. (by @​alexander-akait in #​21524)

  • Speed up the HTML parser and cut its peak memory: module-scope helpers/state and tokenizer callbacks, plus exact AST column pre-sizing. (by @​alexander-akait in #​21492)

  • Track CommonJS build dependencies by parsing sources when require.cache children are unavailable (e.g. Bun). (by @​alexander-akait in #​21531)

  • Cook common string-literal escapes on the JS parser fast path and own the tokenizer's cold-path readers. (by @​alexander-akait in #​21500)

  • Build the CSS parseA* AST on the SoA store instead of node classes, cutting parse memory and time. (by @​alexander-akait in #​21498)

  • Speed up and cut memory of the experimental CSS and HTML parsers: drop two derivable AST node columns, and scan long string, url, comment, and plaintext token bodies natively. (by @​alexander-akait in #​21504)

  • Speed up non-modules CSS parsing: skip redundant token re-reads, drop selector-prelude tokens without materializing nodes, allocate rule preludes lazily, and fast-path empty list seals. (by @​alexander-akait in #​21511)

  • Speed up stats generation and cut its peak memory: reuse cached sort comparators instead of thrashing the comparator caches on every sort, and drop redundant module-graph lookups and allocations in the extractors. (by @​alexander-akait in #​21506)

  • Speed up CSS parsing: byte-range function-name checks, indexed sibling lookahead. (by @​bjohansebas in #​21520)

  • Reduce allocations and redundant work across the code-generation, module-concatenation, exports/usage-analysis, hashing, and chunk-splitting hot paths. (by @​alexander-akait in #​21516)

  • Enable the Node.js compile cache in the webpack CLI entry point. (by @​bjohansebas in #​21523)

  • Encode the persistent cache with V8's value serializer. (by @​avivkeller in #​21514)

  • Speed up SplitChunksPlugin: reject non-subset chunk sets with 64-bit signatures, cache unnamed entry keys, and drop per-module closures. (by @​avivkeller in #​21529)

  • Initialize NormalModule._ast in the constructor so each instance keeps a single hidden-class shape. (by @​alexander-akait in #​21515)

  • Reduce allocations in the binary serialization hot paths. (by @​alexander-akait in #​21526)

  • Deduplicate and simplify several lib modules and speed up AggressiveMergingPlugin. (by @​alexander-akait in #​21525)

  • Default experiments.css, experiments.html and experiments.asyncWebAssembly to "auto", enabling built-in support unless a loader is registered for those files; modules with inline or hook-injected loaders (e.g. html-webpack-plugin templates) keep being parsed as JavaScript. (by @​alexander-akait in #​21365)

  • Add output.resourceHints to emit resource hints (preload/prefetch/modulepreload/preconnect), on by default for ESM output, plus module.parser.<type>.urlHints, css.fontPreload and javascript.dynamicImportCssPreload. (by @​alexander-akait in #​21408)

  • Add built-in build progress via infrastructureLogging.progress, plus estimatedTime, phaseTimings, progress bar width and progressBar: "auto" on ProgressPlugin. (by @​alexander-akait in #​21352)

  • Concatenate CommonJS modules with statically analyzable exports; opt out via optimization.concatenateModules: { commonjs: false }. (by @​alexander-akait in #​21417)

  • Wrap "weird" CommonJS modules into module concatenation instead of bailing out. (by @​alexander-akait in #​21436)

  • Add output.html.inline (true | "script" | "style") and the webpackInline magic comment to inline chunk content into HTML. (by @​alexander-akait in #​21260)

  • Add output.html.inject to control where chunk tags are injected. (by @​alexander-akait in #​21383)

  • Add output.html.title, output.html.meta and output.html.base options for head generation. (by @​alexander-akait in #​21394)

  • Support per-icon link attributes (sizes, media, color, type, crossorigin) and arrays in output.html.favicon. (by @​alexander-akait in #​21487)

  • Add output.html.manifest to generate and link a web app manifest with hashed icons. (by @​alexander-akait in #​21487)

  • Add output.html.csp to inject a Content-Security-Policy meta with inline-content hashes and an optional nonce. (by @​alexander-akait in #​21487)

  • Add the output.html injectTags compilation hook to inject tags (script/link/meta/…) with injectTo placement. (by @​alexander-akait in #​21487)

  • Add the output.html transformTags compilation hook to mutate, remove, or move (between <head> and <body>) a page's existing <script>/<link>/<style>/<meta> tags. (by @​alexander-akait in #​21487)

  • Extend the HTML pipeline with html link sources (bundled as their own emitted page) and rel="preload"/"prefetch" links bundled as chunks. (by @​alexander-akait in #​21346)

  • Recognize more asset-bearing HTML sources: the twitter:player:stream meta, legacy SVG references, and Web App Manifest icons/screenshots/shortcuts URLs. (by @​alexander-akait in #​21355)

  • Add module.parser.html.as to parse HTML as a document or an element fragment. (by @​alexander-akait in #​21441)

  • Allow disabling a built-in HTML parser source via type: false in sources. (by @​alexander-akait in #​21441)

  • Export webpack.html.HtmlModulesPlugin with transformHtml/htmlEmitted compilation hooks. (by @​alexander-akait in #​21487)

  • Resolve @custom-media (including media-type values) and @custom-selector in native CSS. (by @​alexander-akait in #​21442)

  • Scope view-transition-name/-group/-class names and ::view-transition-*() pseudo references in CSS modules under customIdents. (by @​alexander-akait in #​21486)

  • Add import.meta.glob support, with a caseSensitive option and consistent hidden/node_modules matching. (by @​alexander-akait in #​21385)

  • Resolve import.meta.resolve("./asset") to the emitted asset URL via the importMeta.resolve parser option. (by @​alexander-akait in #​21415)

  • Add import.meta.env defaults: MODE, DEV, PROD, SSR and BASE_URL. (by @​alexander-akait in #​21440)

  • Add fine-grained import.meta parser options. (by @​alexander-akait in #​21327)

  • Deprecate the importMetaContext parser option in favor of importMeta.webpackContext. (by @​alexander-akait in #​21360)

  • Add an amd-async externals type that loads AMD externals without an AMD library wrapper. (by @​alexander-akait in #​21340)

  • Support cache.compression: "zstd" for the filesystem cache. (by @​alexander-akait in #​21438)

  • Warn on strict-mode-only syntax and semantic hazards in ES module output, configurable via the strictModeViolations parser option. (by @​alexander-akait in #​21387)

  • Support parsers without location APIs: locations derive from node offsets and AST nodes no longer carry loc. (by @​alexander-akait in #​21451)

  • Attach the original DOM event to ChunkLoadError and ScriptExternalLoadError as error.event. (by @​alexander-akait in #​21388)

  • Add output.wasmStreamingFallback for wasm fallback on a wrong MIME type. (by @​alexander-akait in #​21299)

  • Show why a module was marked as not cacheable in stats output. (by @​alexander-akait in #​21403)

Minor Changes

  • Treat top-level await and import.meta as ES module markers, matching Node.js syntax detection so no explicit module type is needed. (by @​alexander-akait in #​21218)

  • CSS localIdentName [hash] now resolves to the local ident hash (matching css-loader); use [modulehash] for the module hash. (by @​alexander-akait in #​21259)

  • Add CSS parser as option and resolve url() inside HTML style attributes. (by @​alexander-akait in #​21157)

  • Add defineConfig helper for typed configuration files. (by @​alexander-akait in #​21169)

  • Add a deno target (with versions, e.g. deno, deno2, deno1.40) that emits ESM, resolves node.js built-ins via the required node: specifier, and keeps Deno's own import protocols (npm:, jsr:, node:, http(s)://) external. (by @​alexander-akait in #​21247)

  • Use module-import for electron externals when the target supports ESM. (by @​alexander-akait in #​21184)

  • Add module.parser.html.template option to transform HTML module source before parsing. (by @​alexander-akait in #​21055)

  • Extract more source URLs in HTML modules (SVG, legacy and obsolete attributes). (by @​alexander-akait in #​21241)

  • Inline export default <const> when the default-exported value is a primitive constant. (by @​hai-x in #​21189)

  • Support optimization.inlineExports for better tree-shaking. (by @​hai-x in #​20973)

  • Re-encode inline hash digests ([contenthash]/[chunkhash]/[fullhash]/[modulehash]) from the full content hash, so they carry full entropy and work under optimization.realContentHash and in dynamically-loaded chunk filenames; also preserve leading zero bytes in base-N digests. (by @​alexander-akait in #​21267)

  • Allow tree-shaking unused calls to /*#__NO_SIDE_EFFECTS__*/-annotated (pure) exports across module boundaries. (by @​hai-x in #​20907)

  • Defer building unused re-export targets of side-effect-free barrel modules. (by @​hai-x in #​21165)

  • Keep export mangling enabled for modules whose namespace object is used as a whole value, by materializing a decoupled namespace object that keeps the original export names. (by @​alexander-akait in #​21234)

  • Add output.environment.let option (paired with target's let capability) and emit let/const instead of var in generated runtime code wherever it is safe. Bindings that may be wrapped in runtime-condition if blocks (harmony imports, ConcatenatedModule external imports) continue to use var to preserve function scoping. (by @​alexander-akait in #​21010)

Patch Changes

  • Reduce per-file overhead in ContextModuleFactory.resolveDependencies by batching alternativeRequests hook calls. Previously the hook was invoked once per file in the context (with a single-item array), paying per-call overhead (closure allocation, resolverFactory.get, intermediate arrays in RequireContextPlugin) for every file. The hook is now invoked once per directory with all matched files in one batch — RequireContextPlugin's tap already iterates the items array, so the output is unchanged. Steady-state rebuild on a 4000-file require.context drops a further ~15 ms (after the watch-mode purge fix in the same release). (by @​alexander-akait in #​21020)

  • Include each external info's runtimeCondition in ConcatenatedModule#updateHash so changes to a concatenated external's runtime condition invalidate persistent caches instead of slipping through with the module id alone. (by @​alexander-akait in #​21023)

  • Fix HTML [contenthash] for referenced asset and inline-style URL changes. (by @​alexander-akait in #​21018)

  • Resolve chunk-hash placeholders in chunk URLs embedded into extracted HTML. (by @​alexander-akait in #​21018)

  • Remove unnecessary __webpack_require__ runtime helpers in ESM library output with multi-module chunks. (by @​xiaoxiaojx in #​21032)

  • Rewrite NormalModule#getSideEffectsConnectionState walk as an allocation-light iterative loop instead of a generator trampoline, restoring rebuild performance lost in #​20993 while keeping deep import chains stack-safe. (by @​alexander-akait in #​21014)

  • Fix runtime ReferenceError on the first activation of a lazy-compiled module when output.library.type produces a closure-wrapped bundle (umd, umd2, amd, amd-require, system). (by @​alexander-akait in #​21013)

    External modules of these types reference closure-bound identifiers like __WEBPACK_EXTERNAL_MODULE_react__, supplied by the library wrapper that is generated once per chunk. When lazyCompilation activates an entry or import for the first time, any external dependency the lazily-built module pulls in arrives in a hot-update chunk that lives outside the original wrapper closure, so its factory body cannot resolve the closure identifier and only a manual page refresh recovers.

    The inactive LazyCompilationProxyModule now declares statically-enumerable externals (string and object forms of externals) as its own dependencies, so the initial entry chunk's library wrapper already exposes their closure identifiers. When activation later pulls in those externals through the lazily-compiled module, they resolve to the already-installed factories instead of throwing. Function and RegExp externals are not pre-populated because their effective request set isn't knowable up front.

  • Fill in missing entryOptions when an async block joins an existing entrypoint. (by @​alexander-akait in #​21026)

  • Release per-child codeGenerationResults in MultiCompiler and at Compiler.close to reduce memory retention. (by @​alexander-akait in #​21015)

  • Reduce peak memory of SourceMapDevToolPlugin on large builds (closes #​20961). (by @​alexander-akait in #​20963)

  • Fix slow require.context() / dynamic import() rebuilds in watch mode (#​13636). When a file inside a watched context directory changed, NodeWatchFileSystem would call inputFileSystem.purge(contextDir). The enhanced-resolve purge implementation matches cache keys with key.startsWith(contextDir), so the stat cache of every file under the directory was discarded on every rebuild — ContextModuleFactory.resolveDependencies then re-stat-ed the whole tree on each rebuild. Single-file rebuilds on a 4000-file context now reuse the warm stat cache, dropping median rebuild from ~1260 ms to ~650 ms in a local reproduction (≈49%). For directory items that are explicitly watched contexts, purge is now called with { exact: true } (added in enhanced-resolve@5.22.0) so only the directory's own entry is invalidated; file-level changes in the same aggregated event continue to purge file stats and the parent readdir as before.

Patch Changes

  • Align the experimental HTML tokenizer with the WHATWG spec: fix offset-range bugs in the script-data, content-mode end-tag, attribute-value, and EOF states; surface tokenizer parse errors to consumers via a new parseError callback ("warning" when the tokenizer recovers and the emitted token is still well-formed, "error" when the offset range is incomplete — e.g. eof-in-tag); and add the full WHATWG named character references table so decodeHtmlEntities handles all named entities (including legacy bare forms like &AMP and multi-code-point entities like &NotEqualTilde;) with proper longest-prefix backtracking. (by @​alexander-akait in #​21000)

  • Tree-shake CommonJS modules imported through a const NAME = require(LITERAL) binding when only static members of NAME are read. Previously webpack treated every export of such modules as referenced (because the bare require() dependency reports EXPORTS_OBJECT_REFERENCED), so unused exports.x = ... assignments remained in the bundle even with usedExports enabled. The parser now forwards NAME.x / NAME.x() / NAME["x"] accesses to the underlying CommonJsRequireDependency as referenced exports, falling back to the full exports object the moment NAME is read in any other context (passed by value, destructured later, accessed with a dynamic key, …). This brings the binding form to parity with the existing destructuring form (const { x } = require(...)). (by @​alexander-akait in #​21003)

  • Fix RangeError: Maximum call stack size exceeded thrown from HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState on long linear chains of side-effect-free imports. NormalModule.getSideEffectsConnectionState previously descended through HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState recursively, adding two stack frames per module, which overflowed V8's stack at a few thousand modules deep. The traversal is now iterative. (by @​alexander-akait in #​20993)

  • Fix NormalModuleFactory parser/generator types: (by @​alexander-akait in #​20999)

    • module.generator.html now uses HtmlGeneratorOptions instead of EmptyGeneratorOptions (the extract option was hidden from the createGenerator / generator hook types).
    • WebAssembly (webassembly/async, webassembly/sync) generator hooks now use EmptyGeneratorOptions instead of EmptyParserOptions.
    • NormalModuleFactory#getParser / createParser / getGenerator / createGenerator are now generic over the module-type string, returning the specific parser/generator class for known types (e.g. JavascriptParser for "javascript/auto", CssGenerator for "css", etc.) instead of always returning the base Parser / Generator.
    • NormalModuleCreateData is now generic over the module type so parser, parserOptions, generator, and generatorOptions are narrowed to the specific class / options for the given type.

  • Link import bindings used inside define(...) callbacks in ES modules. Previously, HarmonyDetectionParserPlugin skipped walking the arguments of define calls in harmony modules, so references to imported bindings inside an inline AMD define factory (e.g. define(function () { console.log(foo); })) were not rewritten to their imported references and could cause ReferenceError at runtime. Inner graph usage analysis is also fixed for the related pattern const fn = function () { foo; }; define(fn);. (by @​alexander-akait in #​20990)

  • HTML-entry pipeline (experiments.html + experiments.css): emit <link rel="stylesheet"> tags for CSS chunks reachable from a <script src> entry. Previously when the bundled JS imported CSS, the resulting .css file was emitted to disk but never referenced from the extracted HTML (no <link> tag), and when splitChunks extracted CSS into sibling chunks the HTML cloned the originating <script> for each one — producing <script src="style.js"> pointing at non-existent JS filenames instead of <link rel="stylesheet" href="style.css">. CSS chunks are now sorted by the entrypoint's module post-order index so the <link> tags also appear in source import order, fixing the cascade ordering issue documented in html-webpack-plugin#1838 and webpack/mini-css-extract-plugin#959 for HTML-entry builds. nonce/crossorigin/referrerpolicy are copied from the originating tag onto the emitted <link>. (by @​alexander-akait in #​21002)

  • Allow devtool and SourceMapDevToolPlugin (or multiple SourceMapDevToolPlugin instances) to coexist on the same asset. Previously the second instance would silently skip any asset whose info.related.sourceMap had already been set by an earlier instance, and even when it ran the asset had been rewrapped as a RawSource so no source map could be recovered — producing an empty .map file. The plugin now keeps a per-compilation stash of pristine source maps, namespaces its persistent cache entries by the options that affect output, and appends additional related.sourceMap entries instead of overwriting them. The classic workaround of pairing devtool: 'hidden-source-map' with a new webpack.SourceMapDevToolPlugin({ filename: '[file].secondary.map', noSources: true }) now produces both maps in a single build. (by @​alexander-akait in #​21001)

  • Narrow TemplatePathFn callback types by context. pathData.chunk is now non-optional for chunk filename callbacks (output.filename, chunkFilename, cssFilename, cssChunkFilename, htmlFilename, htmlChunkFilename, optimization.splitChunks.cacheGroups[*].filename), and pathData.module is non-optional for module filename callbacks (output.assetModuleFilename, per-module generator.filename / generator.outputPath, module.parser.css.localIdentName). (by @​alexander-akait in #​20987)

  • Tighten the CreateData typedef in NormalModuleFactory. CreateData now represents the fully-populated value passed to the createModule, module, and createModuleClass hooks (NormalModuleCreateData & { settings: ModuleSettings }), while ResolveData.createData is typed as Partial<CreateData> to reflect the empty initial state. Plugins tapping those hooks no longer need to cast individual fields away from optional. (by @​alexander-akait in #​20992)

  • Stop webpackPrefetch / webpackPreload magic comments from leaking across import() call sites that share a webpackChunkName. When two imports targeted the same named chunk and only one of them set webpackPrefetch: true, the prefetch directive was applied from every parent chunk that referenced the named chunk. Prefetch and preload orders are now resolved per import() call site instead of from the shared chunk group's accumulated options. (by @​alexander-akait in #​20994)

  • Fix [fullhash:N] and [hash:N] (with length suffix) in output.publicPath not being interpolated at runtime. The detection regex in RuntimePlugin only matched [fullhash] / [hash] without a length suffix, so the PublicPathRuntimeModule was not flagged as a full-hash module and __webpack_require__.p was emitted with the placeholder XXXX left in place (e.g. out/XXXX/) instead of the real hash truncated to the requested length. (by @​alexander-akait in #​21004)

  • Re-export ModuleNotFoundError from webpack/lib/ModuleNotFoundError for backward compatibility with old plugins that import it from that path. This re-export will be removed in webpack 6. (by @​alexander-akait in #​20988)

Minor Changes

  • Add module.generator.javascript.anonymousDefaultExportName option to control whether webpack sets .name to "default" for anonymous default export functions and classes per ES spec. Defaults to true for applications and false for libraries (when output.library is set) to avoid unnecessary bundle size overhead. Also extract anonymous default export .name fix-up into a shared runtime helper (__webpack_require__.dn), replacing repeated inline Object.defineProperty / Object.getOwnPropertyDescriptor calls with a single short call per module to reduce output size. (by @​xiaoxiaojx in #​20894)

  • Support module concatenation (scope hoisting) for CSS modules with text, css-style-sheet, style, and link export types (by @​xiaoxiaojx in #​20851)

  • The generator.exportsConvention function form for CSS modules now accepts string[] in addition to string. (by @​alexander-akait in #​20914)

  • Add linkInsert hook to CssLoadingRuntimeModule.getCompilationHooks(compilation) so plugin developers can control where stylesheet <link> elements are inserted into the document. (by @​alexander-akait in #​20947)

  • Add CssModulesPlugin.getCompilationHooks(compilation).orderModules hook. (by @​alexander-akait in #​20978)

  • Add a pure parser option for css/module and css/auto types matching postcss-modules-local-by-default's pure mode: every selector must contain at least one local class or id, otherwise webpack emits a build error. (by @​alexander-akait in #​20946)

  • Support CSS Modules @value identifiers as @import URLs and inside url() functions, e.g. @value path: "./other.css"; @import path; and @value bg: "./image.png"; .a { background: url(bg); } (by @​alexander-akait in #​20925)

  • Add experimental TypeScript support via experiments.typescript: true (auto-enabled by experiments.futureDefaults). Uses Node.js's built-in module.stripTypeScriptTypes (Node.js >= 22.6 with the stable mode: "strip" API, including Node.js 26) to transform .ts, .cts, .mts, data:text/typescript, and data:application/typescript modules — no type checking, only erasable TypeScript (types, generics, import type, casts). .tsx/JSX and non-erasable syntax (enum, namespace, parameter-property constructors, decorator metadata) are NOT supported; use a TSX-capable loader (e.g. ts-loader, swc-loader) for those. (by @​alexander-akait in #​20964)

  • Added an experiments.html flag that reserves the html module type for the first-class HTML entry-point support. (by @​aryanraj45 in #​20902)

  • Preserve defer / source import phase keywords on external dependencies in ESM output, the same way import attributes are preserved. (by @​alexander-akait in #​20934)

  • Support the #__NO_SIDE_EFFECTS__ annotation to mark functions as pure for better tree-shaking. (by @​hai-x in #​20775)

  • Add module.generator.html.extract for HTML modules and the matching output.htmlFilename / output.htmlChunkFilename filename templates (defaults derived from output.filename / output.chunkFilename with .js swapped for .html, mirroring the CSS pipeline). When extraction is on, the parsed and URL-rewritten HTML is emitted as a standalone .html output file alongside the module's JavaScript export. (by @​alexander-akait in #​20979)

  • Add "module-sync" to default conditionNames for resolver defaults to align with Node.js, which exposes the module-sync community condition for synchronously-loadable ESM. (by @​alexander-akait in #​20933)

Patch Changes

  • Fix CSS modules composes so composes: foo from "./self.module.css" from inside self.module.css no longer creates a duplicate module instance. Fix CSS modules composes parsing so local() and global() function wrappers are tracked per class name. Fix CSS modules composes: ... from "<file>" so the composed files load in an order consistent with every rule's local composes order, instead of source first-appearance order. (by @​alexander-akait in #​20929)

  • Avoid emitting the __webpack_require__ runtime in CSS bundles when all imported CSS modules were concatenated into the same scope. (by @​alexander-akait in #​20936)

  • Recompute the CSS chunk's [contenthash] and the rendered CSS bytes when an asset referenced by url()/src()/string in CSS changes its hashed filename. (by @​alexander-akait in #​20938)

  • Embed an inline sourceMappingURL data URI inside the CSS when the parser.exportType option are text, style, or css-style-sheet. Also merge @imported CSS at build time for text and css-style-sheet exportTypes so the bundle ships a single accurate inline source map covering every contributing file. Map each generated CSS-module class export line in the JS bundle back to its selector position in the original CSS file (e.g. btn: "..." → .btn { ... }). (by @​alexander-akait in #​20886)

  • Fix CSS modules deduplication so a .module.<ext> file imported both directly (JS) and via icss (composes from / :import) becomes a single module instance. (by @​alexander-akait in #​20929)

  • Preserve @charset at-rule when CSS modules use exportType: "text". (by @​alexander-akait in #​20912)

  • Resolve [hash]/[fullhash] placeholders in output.publicPath when generating url() references for experiments.css. (by @​alexander-akait in #​20879)

  • Fix HMR for concatenated CSS modules with style exportType by using stable per-module identifiers for injected style elements and tracking inner module IDs of concatenated modules in HMR records (by @​xiaoxiaojx in #​20911)

  • Fix CSS Modules @value resolution when the same local name is imported from multiple modules. (by @​alexander-akait in #​20940)

  • Fix typeof ns.default / ns.default instanceof X on a static import defer * as ns from "./mod" for default-only and default-with-named external modules under optimization.concatenateModules. The concatenated-module rewrite was collapsing ns.default to the deferred-namespace proxy itself instead of routing through the optimized .a getter (which lazily evaluates the module and returns its default value), so typeof ns.default observed "object" (the proxy) rather than the type of the default. The dynamic exportsType already used .a correctly; default-only and default-with-named now match. (by @​alexander-akait in #​20910)

  • Make import defer * as ns more spec-compliant: ns.x = value no longer triggers module evaluation (per the TC39 import-defer [[Set]] algorithm), and the deferred namespace is now a distinct object from the eager namespace, with the same Deferred Module Namespace Exotic Object shared across defer-import call sites for the same module. (by @​alexander-akait in #​20913)

  • Fixed spec deviations in the deferred namespace object returned by __webpack_require__.z (import defer * as ns / import.defer(...)). (by @​alexander-akait in #​20910)

  • Drop the __webpack_require__, __webpack_require__.d, and __webpack_require__.o runtime helpers from library: { type: "module" } bundles when the on-demand exports source they were emitted for ends up dropped (e.g. a single concatenated entry without an IIFE). (by @​alexander-akait in #​20901)

  • Resolve the static specifier of a dynamic import() whose argument is a side-effect-free SequenceExpression, e.g. import((1, 0, "./mod.js")) is now treated the same as import("./mod.js") instead of being rejected as unresolvable. (by @​alexander-akait in #​20917)

  • Stable shared module ids and runtime-chunk emission order. (by @​imccausl in #​20860)

  • Fix snapshot validity check for context dependencies in watch mode by treating watchpack's existence-only entries ({}) as cache misses. (by @​alexander-akait in #​20916)

  • Support no-expression template literals in computed member access (e.g. import.meta[`url`]). (by @​alexander-akait in #​20889)

  • Improve tree-shaking in isPure: handle more expression types (ArrayExpression, ObjectExpression, NewExpression, ChainExpression, UnaryExpression (safe operators), MetaProperty, TaggedTemplateExpression, BinaryExpression (strict equality)), prevent /*#__PURE__*/ comments from leaking across ObjectExpression properties, and detect PURE comments inside TemplateLiteral interpolations. (by @​alexander-akait in #​20723)

  • Reject new import.defer(...) and new import.source(...) as a parse-time SyntaxError, matching the spec — ImportCall is a CallExpression and is not a valid operand of new. Parenthesized forms (new (import.defer(...))) remain valid and continue to throw TypeError at runtime as before. (by @​alexander-akait in #​20917)

  • Escape # characters that appear inside a path-shaped request's directory portion before passing the request to the resolver, so projects located in directories like /home/user/proj#1 (and tools like webpack-dev-server that build entry requests with query strings) resolve correctly. The escape only kicks in when the request contains both a # in the path portion and a ? query string — paths without a query keep their existing semantics. (by @​alexander-akait in #​20980)

  • Silence unhandled rejection from the prefetch trigger when chunk loading fails. The ensureChunkHandlers.prefetch runtime created Promise.all(promises).then(...) whose result is discarded by __webpack_require__.e. If chunk loading rejected (e.g. chunkLoadTimeout), that dangling chain produced an unhandled rejection. Prefetch is best-effort, so a no-op rejection handler is now attached. (by @​alexander-akait in #​20898)

  • Align require() of an ES module with Node.js's require(esm) "module.exports" named-export convention. When CommonJS require() resolves to an ES module that exports a binding with the literal string name "module.exports" (e.g. export { value as "module.exports" }), require() now returns the value of that export instead of the module's namespace object — matching Node.js v22.12+/v23+ behavior and easing migration of dual ESM/CJS libraries that rely on module.exports = …. The unwrap applies to plain require(), require().foo, calls (require()(…)), destructuring, and to CJS wrappers like module.exports = require(esm) / exports.x = require(esm). (by @​alexander-akait in #​20981)

  • Remove outdated @types/eslint-scope package from dependencies. (by @​alexander-akait in #​20869)

  • Fix export * resolution when a star-reexported module re-exports a name back to the importer cyclically. Previously, in a graph where a does export * from "./b"; export * from "./c"; and b does export { foo } from "./a"; while c provides the actual foo binding, webpack hoisted foo from b into a's namespace without per-name cycle detection — emitting a getter chain (a.foo → b.foo → a.foo) that threw "Maximum call stack size exceeded" at runtime. The TC39 ResolveExport algorithm requires the cyclic branch to return null and the star loop to fall through to the non-cyclic source. (by @​alexander-akait in #​20959)

  • Preserve using declaration initializers when the inner graph optimization is enabled. (by @​hai-x in #​20906)

  • Fixed typescript types. (by @​alexander-akait in #​20880)

  • Bump webpack-sources to ^3.4.1 and feed asset bytes into hashes via the new Source.prototype.buffers() API. For large ConcatSource/ReplaceSource outputs this avoids the intermediate Buffer.concat that source.buffer() performs, removing a peak-memory spike equal to the source's total size on each hashed asset (AssetGenerator.getFullContentHash, CssIcssExportDependency content hashing, and RealContentHashPlugin). A small benchmark on a 64 MiB ConcatSource shows ~64 MiB lower peak external memory and ~45% faster hashing. (by @​alexander-akait in #​20897)

Patch Changes

  • Fix two ES5-environment regressions in the anonymous default export .name fix-up: the generated code referenced an undeclared __WEBPACK_DEFAULT_EXPORT__ binding causing ReferenceError, and used Reflect.defineProperty which is not available in pre-ES2015 runtimes. The fix-up now references the real assignment target and uses Object.defineProperty / Object.getOwnPropertyDescriptor. (by @​xiaoxiaojx in #​20796)

  • Prevent !important from being renamed as a local identifier in CSS modules. (by @​xiaoxiaojx in #​20798)

  • Use compiler context instead of module context for CSS modules local ident hashing to avoid hash collisions when files with the same name exist in different directories. (by @​xiaoxiaojx in #​20799)

  • Add context option support for VirtualUrlPlugin (by @​xiaoxiaojx in #​20449)

    • The context for the virtual module. A string path. Defaults to 'auto', which will try to resolve the context from the module id.
    • Support custom context path for resolving relative imports in virtual modules
    • Add examples demonstrating context usage and filename customization

  • Generate different CssModule instances for different exportType values. (by @​xiaoxiaojx in #​20590)

  • Added the localIdentHashFunction option to configure the hash function to be used for hashing. (by @​alexander-akait in #​20694)
    Additionally, the localIdentName option can now be a function.

  • Added support for destructuring assignment require in cjs, allowing for tree shaking. (by @​ahabhgk in #​20548)

  • Hash entry chunks after runtime chunks to prevent stale content hash references in watch mode (by @​xiaoxiaojx in #​20724)

  • Fix multiple bugs and optimizations in CSS modules: correct third code point position in walkCssTokens number detection, fix multiline CSS comment regex, fix swapped :import/:export error message, fix comma callback incorrectly popping balanced stack, fix cache comparison missing array length check, fix match.index mutation side effect, move publicPathAutoRegex to module scope, precompute merged callbacks in consumeUntil, simplify redundant ternary in CssGenerator, fix typo GRID_TEMPLATE_ARES, remove duplicate grid-column-start, and merge duplicate getCompilationHooks calls.

  • Correct url() path resolution and preserve source maps for non-link CSS export types (style, text, css-style-sheet) (by @​xiaoxiaojx in #​20717)

  • Emit error when proxy server returns non-200 status code in HttpUriPlugin instead of silently failing. (by @​xiaoxiaojx in #​20646)

  • import.meta as standalone expression now returns a complete object with known properties (url, webpack, main, env) instead of an empty object ({}), and hoists it as a module-level variable to ensure import.meta === import.meta identity. In preserve-unknown mode (ESM output), the hoisted object merges runtime import.meta properties via Object.assign. (by @​xiaoxiaojx in #​20658)

  • Fix incorrect condition in FileSystemInfo that always evaluated to false, preventing trailing slash removal from directory paths during build dependency resolution. (by @​xiaoxiaojx in #​20649)

  • fix: VirtualUrlPlugin absolute path virtual module IDs getting concatenated with compiler context (by @​xiaoxiaojx in #​20656)

    When a virtual module ID is an absolute path (e.g. virtual:C:/project/user.js), the auto-derived context was incorrectly joined with compiler.context, producing a concatenated path like C:\cwd\C:\project. Now absolute-path contexts are used directly.

  • All deprecated methods and options now have @deprecated flag in types. (by @​alexander-akait in #​20707)

(by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21223](https://github.com/webpack/webpack/pull/21223)) ### [`v5.107.2`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51072) [Compare Source](https://github.com/webpack/webpack/compare/v5.107.1...v5.107.2) ##### Patch Changes - Reduce per-file overhead in `ContextModuleFactory.resolveDependencies` by batching `alternativeRequests` hook calls. Previously the hook was invoked once per file in the context (with a single-item array), paying per-call overhead (closure allocation, `resolverFactory.get`, intermediate arrays in `RequireContextPlugin`) for every file. The hook is now invoked once per directory with all matched files in one batch — `RequireContextPlugin`'s tap already iterates the items array, so the output is unchanged. Steady-state rebuild on a 4000-file `require.context` drops a further \~15 ms (after the watch-mode purge fix in the same release).

(by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21014](https://github.com/webpack/webpack/pull/21014)) - Fix runtime `ReferenceError` on the first activation of a lazy-compiled module when `output.library.type` produces a closure-wrapped bundle (`umd`, `umd2`, `amd`, `amd-require`, `system`). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21013](https://github.com/webpack/webpack/pull/21013)) External modules of these types reference closure-bound identifiers like `__WEBPACK_EXTERNAL_MODULE_react__`, supplied by the library wrapper that is generated once per chunk. When `lazyCompilation` activates an entry or import for the first time, any external dependency the lazily-built module pulls in arrives in a hot-update chunk that lives outside the original wrapper closure, so its factory body cannot resolve the closure identifier and only a manual page refresh recovers. The inactive `LazyCompilationProxyModule` now declares statically-enumerable externals (string and object forms of `externals`) as its own dependencies, so the initial entry chunk's library wrapper already exposes their closure identifiers. When activation later pulls in those externals through the lazily-compiled module, they resolve to the already-installed factories instead of throwing. Function and RegExp externals are not pre-populated because their effective request set isn't knowable up front. - Fill in missing `entryOptions` when an async block joins an existing entrypoint.

(by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20963](https://github.com/webpack/webpack/pull/20963)) - Fix slow `require.context()` / dynamic `import()` rebuilds in watch mode ([#&#8203;13636](https://github.com/webpack/webpack/issues/13636)). When a file inside a watched context directory changed, `NodeWatchFileSystem` would call `inputFileSystem.purge(contextDir)`. The enhanced-resolve `purge` implementation matches cache keys with `key.startsWith(contextDir)`, so the stat cache of every file under the directory was discarded on every rebuild — `ContextModuleFactory.resolveDependencies` then re-`stat`-ed the whole tree on each rebuild. Single-file rebuilds on a 4000-file context now reuse the warm stat cache, dropping median rebuild from \~1260 ms to \~650 ms in a local reproduction (≈49%). For directory items that are explicitly watched contexts, `purge` is now called with `{ exact: true }` (added in `enhanced-resolve@5.22.0`) so only the directory's own entry is invalidated; file-level changes in the same aggregated event continue to purge file stats and the parent `readdir` as before. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21020](https://github.com/webpack/webpack/pull/21020)) ### [`v5.107.1`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51071) [Compare Source](https://github.com/webpack/webpack/compare/v5.107.0...v5.107.1) ##### Patch Changes - Align the experimental HTML tokenizer with the WHATWG spec: fix offset-range bugs in the script-data, content-mode end-tag, attribute-value, and EOF states; surface tokenizer parse errors to consumers via a new `parseError` callback (`"warning"` when the tokenizer recovers and the emitted token is still well-formed, `"error"` when the offset range is incomplete — e.g. `eof-in-tag`); and add the full WHATWG named character references table so `decodeHtmlEntities` handles all named entities (including legacy bare forms like `&AMP` and multi-code-point entities like `&NotEqualTilde;`) with proper longest-prefix backtracking. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21000](https://github.com/webpack/webpack/pull/21000)) - Tree-shake CommonJS modules imported through a `const NAME = require(LITERAL)` binding when only static members of `NAME` are read. Previously webpack treated every export of such modules as referenced (because the bare `require()` dependency reports `EXPORTS_OBJECT_REFERENCED`), so unused `exports.x = ...` assignments remained in the bundle even with `usedExports` enabled. The parser now forwards `NAME.x` / `NAME.x()` / `NAME["x"]` accesses to the underlying `CommonJsRequireDependency` as referenced exports, falling back to the full exports object the moment `NAME` is read in any other context (passed by value, destructured later, accessed with a dynamic key, …). This brings the binding form to parity with the existing destructuring form (`const { x } = require(...)`). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21003](https://github.com/webpack/webpack/pull/21003)) - Fix `RangeError: Maximum call stack size exceeded` thrown from `HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState` on long linear chains of side-effect-free imports. `NormalModule.getSideEffectsConnectionState` previously descended through `HarmonyImportSideEffectDependency.getModuleEvaluationSideEffectsState` recursively, adding two stack frames per module, which overflowed V8's stack at a few thousand modules deep. The traversal is now iterative. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20993](https://github.com/webpack/webpack/pull/20993)) - Fix `NormalModuleFactory` parser/generator types: (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20999](https://github.com/webpack/webpack/pull/20999)) - `module.generator.html` now uses `HtmlGeneratorOptions` instead of `EmptyGeneratorOptions` (the `extract` option was hidden from the `createGenerator` / `generator` hook types). - WebAssembly (`webassembly/async`, `webassembly/sync`) generator hooks now use `EmptyGeneratorOptions` instead of `EmptyParserOptions`. - `NormalModuleFactory#getParser` / `createParser` / `getGenerator` / `createGenerator` are now generic over the module-type string, returning the specific parser/generator class for known types (e.g. `JavascriptParser` for `"javascript/auto"`, `CssGenerator` for `"css"`, etc.) instead of always returning the base `Parser` / `Generator`. - `NormalModuleCreateData` is now generic over the module type so `parser`, `parserOptions`, `generator`, and `generatorOptions` are narrowed to the specific class / options for the given `type`. - Link import bindings used inside `define(...)` callbacks in ES modules. Previously, `HarmonyDetectionParserPlugin` skipped walking the arguments of `define` calls in harmony modules, so references to imported bindings inside an inline AMD `define` factory (e.g. `define(function () { console.log(foo); })`) were not rewritten to their imported references and could cause `ReferenceError` at runtime. Inner graph usage analysis is also fixed for the related pattern `const fn = function () { foo; }; define(fn);`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20990](https://github.com/webpack/webpack/pull/20990)) - HTML-entry pipeline (`experiments.html` + `experiments.css`): emit `<link rel="stylesheet">` tags for CSS chunks reachable from a `<script src>` entry. Previously when the bundled JS imported CSS, the resulting `.css` file was emitted to disk but never referenced from the extracted HTML (no `<link>` tag), and when `splitChunks` extracted CSS into sibling chunks the HTML cloned the originating `<script>` for each one — producing `<script src="style.js">` pointing at non-existent JS filenames instead of `<link rel="stylesheet" href="style.css">`. CSS chunks are now sorted by the entrypoint's module post-order index so the `<link>` tags also appear in source import order, fixing the cascade ordering issue documented in `html-webpack-plugin#1838` and `webpack/mini-css-extract-plugin#959` for HTML-entry builds. `nonce`/`crossorigin`/`referrerpolicy` are copied from the originating tag onto the emitted `<link>`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21002](https://github.com/webpack/webpack/pull/21002)) - Allow `devtool` and `SourceMapDevToolPlugin` (or multiple `SourceMapDevToolPlugin` instances) to coexist on the same asset. Previously the second instance would silently skip any asset whose `info.related.sourceMap` had already been set by an earlier instance, and even when it ran the asset had been rewrapped as a `RawSource` so no source map could be recovered — producing an empty `.map` file. The plugin now keeps a per-compilation stash of pristine source maps, namespaces its persistent cache entries by the options that affect output, and appends additional `related.sourceMap` entries instead of overwriting them. The classic workaround of pairing `devtool: 'hidden-source-map'` with a `new webpack.SourceMapDevToolPlugin({ filename: '[file].secondary.map', noSources: true })` now produces both maps in a single build. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21001](https://github.com/webpack/webpack/pull/21001)) - Narrow `TemplatePathFn` callback types by context. `pathData.chunk` is now non-optional for chunk filename callbacks (`output.filename`, `chunkFilename`, `cssFilename`, `cssChunkFilename`, `htmlFilename`, `htmlChunkFilename`, `optimization.splitChunks.cacheGroups[*].filename`), and `pathData.module` is non-optional for module filename callbacks (`output.assetModuleFilename`, per-module `generator.filename` / `generator.outputPath`, `module.parser.css.localIdentName`). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20987](https://github.com/webpack/webpack/pull/20987)) - Tighten the `CreateData` typedef in `NormalModuleFactory`. `CreateData` now represents the fully-populated value passed to the `createModule`, `module`, and `createModuleClass` hooks (`NormalModuleCreateData & { settings: ModuleSettings }`), while `ResolveData.createData` is typed as `Partial<CreateData>` to reflect the empty initial state. Plugins tapping those hooks no longer need to cast individual fields away from optional. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20992](https://github.com/webpack/webpack/pull/20992)) - Stop `webpackPrefetch` / `webpackPreload` magic comments from leaking across `import()` call sites that share a `webpackChunkName`. When two imports targeted the same named chunk and only one of them set `webpackPrefetch: true`, the prefetch directive was applied from every parent chunk that referenced the named chunk. Prefetch and preload orders are now resolved per `import()` call site instead of from the shared chunk group's accumulated options. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20994](https://github.com/webpack/webpack/pull/20994)) - Fix `[fullhash:N]` and `[hash:N]` (with length suffix) in `output.publicPath` not being interpolated at runtime. The detection regex in `RuntimePlugin` only matched `[fullhash]` / `[hash]` without a length suffix, so the `PublicPathRuntimeModule` was not flagged as a full-hash module and `__webpack_require__.p` was emitted with the placeholder `XXXX` left in place (e.g. `out/XXXX/`) instead of the real hash truncated to the requested length. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;21004](https://github.com/webpack/webpack/pull/21004)) - Re-export `ModuleNotFoundError` from `webpack/lib/ModuleNotFoundError` for backward compatibility with old plugins that import it from that path. This re-export will be removed in webpack 6. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20988](https://github.com/webpack/webpack/pull/20988)) ### [`v5.107.0`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51070) [Compare Source](https://github.com/webpack/webpack/compare/v5.106.2...v5.107.0) ##### Minor Changes - Add `module.generator.javascript.anonymousDefaultExportName` option to control whether webpack sets `.name` to `"default"` for anonymous default export functions and classes per ES spec. Defaults to `true` for applications and `false` for libraries (when `output.library` is set) to avoid unnecessary bundle size overhead. Also extract anonymous default export `.name` fix-up into a shared runtime helper (`__webpack_require__.dn`), replacing repeated inline `Object.defineProperty` / `Object.getOwnPropertyDescriptor` calls with a single short call per module to reduce output size. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20894](https://github.com/webpack/webpack/pull/20894)) - Support module concatenation (scope hoisting) for CSS modules with `text`, `css-style-sheet`, `style`, and `link` export types (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20851](https://github.com/webpack/webpack/pull/20851)) - The `generator.exportsConvention` function form for CSS modules now accepts `string[]` in addition to `string`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20914](https://github.com/webpack/webpack/pull/20914)) - Add `linkInsert` hook to `CssLoadingRuntimeModule.getCompilationHooks(compilation)` so plugin developers can control where stylesheet `<link>` elements are inserted into the document.

(by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20978](https://github.com/webpack/webpack/pull/20978)) - Add a `pure` parser option for `css/module` and `css/auto` types matching `postcss-modules-local-by-default`'s pure mode: every selector must contain at least one local class or id, otherwise webpack emits a build error. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20946](https://github.com/webpack/webpack/pull/20946)) - Support CSS Modules `@value` identifiers as `@import` URLs and inside `url()` functions, e.g. `@value path: "./other.css"; @import path;` and `@value bg: "./image.png"; .a { background: url(bg); }` (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20925](https://github.com/webpack/webpack/pull/20925)) - Add experimental TypeScript support via `experiments.typescript: true` (auto-enabled by `experiments.futureDefaults`). Uses Node.js's built-in `module.stripTypeScriptTypes` (Node.js >= 22.6 with the stable `mode: "strip"` API, including Node.js 26) to transform `.ts`, `.cts`, `.mts`, `data:text/typescript`, and `data:application/typescript` modules — no type checking, only erasable TypeScript (types, generics, `import type`, casts). `.tsx`/JSX and non-erasable syntax (`enum`, `namespace`, parameter-property constructors, decorator metadata) are NOT supported; use a TSX-capable loader (e.g. `ts-loader`, `swc-loader`) for those. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20964](https://github.com/webpack/webpack/pull/20964)) - Added an `experiments.html` flag that reserves the `html` module type for the first-class HTML entry-point support. (by [@&#8203;aryanraj45](https://github.com/aryanraj45) in [#&#8203;20902](https://github.com/webpack/webpack/pull/20902)) - Preserve `defer` / `source` import phase keywords on external dependencies in ESM output, the same way import attributes are preserved.

(by [@&#8203;hai-x](https://github.com/hai-x) in [#&#8203;20775](https://github.com/webpack/webpack/pull/20775)) - Add `module.generator.html.extract` for HTML modules and the matching `output.htmlFilename` / `output.htmlChunkFilename` filename templates (defaults derived from `output.filename` / `output.chunkFilename` with `.js` swapped for `.html`, mirroring the CSS pipeline). When extraction is on, the parsed and URL-rewritten HTML is emitted as a standalone `.html` output file alongside the module's JavaScript export. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20979](https://github.com/webpack/webpack/pull/20979)) - Add `"module-sync"` to default `conditionNames` for resolver defaults to align with Node.js, which exposes the `module-sync` community condition for synchronously-loadable ESM. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20933](https://github.com/webpack/webpack/pull/20933)) ##### Patch Changes - Fix CSS modules `composes` so `composes: foo from "./self.module.css"` from inside `self.module.css` no longer creates a duplicate module instance. Fix CSS modules `composes` parsing so `local()` and `global()` function wrappers are tracked per class name. Fix CSS modules `composes: ... from "<file>"` so the composed files load in an order consistent with every rule's local composes order, instead of source first-appearance order. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20929](https://github.com/webpack/webpack/pull/20929)) - Avoid emitting the `__webpack_require__` runtime in CSS bundles when all imported CSS modules were concatenated into the same scope. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20936](https://github.com/webpack/webpack/pull/20936)) - Recompute the CSS chunk's `[contenthash]` and the rendered CSS bytes when an asset referenced by `url()`/`src()`/string in CSS changes its hashed filename. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20938](https://github.com/webpack/webpack/pull/20938)) - Embed an inline `sourceMappingURL` data URI inside the CSS when the `parser.exportType` option are `text`, `style`, or `css-style-sheet`. Also merge `@import`ed CSS at build time for `text` and `css-style-sheet` exportTypes so the bundle ships a single accurate inline source map covering every contributing file. Map each generated CSS-module class export line in the JS bundle back to its selector position in the original CSS file (e.g. `btn: "..."` → `.btn { ... }`). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20886](https://github.com/webpack/webpack/pull/20886)) - Fix CSS modules deduplication so a `.module.<ext>` file imported both directly (JS) and via icss (`composes from` / `:import`) becomes a single module instance. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20929](https://github.com/webpack/webpack/pull/20929)) - Preserve `@charset` at-rule when CSS modules use `exportType: "text"`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20912](https://github.com/webpack/webpack/pull/20912)) - Resolve `[hash]`/`[fullhash]` placeholders in `output.publicPath` when generating `url()` references for `experiments.css`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20879](https://github.com/webpack/webpack/pull/20879)) - Fix HMR for concatenated CSS modules with `style` exportType by using stable per-module identifiers for injected style elements and tracking inner module IDs of concatenated modules in HMR records (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20911](https://github.com/webpack/webpack/pull/20911)) - Fix CSS Modules `@value` resolution when the same local name is imported from multiple modules. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20940](https://github.com/webpack/webpack/pull/20940)) - Fix `typeof ns.default` / `ns.default instanceof X` on a static `import defer * as ns from "./mod"` for `default-only` and `default-with-named` external modules under `optimization.concatenateModules`. The concatenated-module rewrite was collapsing `ns.default` to the deferred-namespace proxy itself instead of routing through the optimized `.a` getter (which lazily evaluates the module and returns its default value), so `typeof ns.default` observed `"object"` (the proxy) rather than the type of the default. The `dynamic` exportsType already used `.a` correctly; default-only and default-with-named now match. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20910](https://github.com/webpack/webpack/pull/20910)) - Make `import defer * as ns` more spec-compliant: `ns.x = value` no longer triggers module evaluation (per the TC39 import-defer `[[Set]]` algorithm), and the deferred namespace is now a distinct object from the eager namespace, with the same Deferred Module Namespace Exotic Object shared across defer-import call sites for the same module. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20913](https://github.com/webpack/webpack/pull/20913)) - Fixed spec deviations in the deferred namespace object returned by `__webpack_require__.z` (`import defer * as ns` / `import.defer(...)`). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20910](https://github.com/webpack/webpack/pull/20910)) - Drop the `__webpack_require__`, `__webpack_require__.d`, and `__webpack_require__.o` runtime helpers from `library: { type: "module" }` bundles when the on-demand exports source they were emitted for ends up dropped (e.g. a single concatenated entry without an IIFE). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20901](https://github.com/webpack/webpack/pull/20901)) - Resolve the static specifier of a dynamic `import()` whose argument is a side-effect-free `SequenceExpression`, e.g. `import((1, 0, "./mod.js"))` is now treated the same as `import("./mod.js")` instead of being rejected as unresolvable. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20917](https://github.com/webpack/webpack/pull/20917)) - Stable shared module ids and runtime-chunk emission order. (by [@&#8203;imccausl](https://github.com/imccausl) in [#&#8203;20860](https://github.com/webpack/webpack/pull/20860)) - Fix snapshot validity check for context dependencies in watch mode by treating watchpack's existence-only entries (`{}`) as cache misses. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20916](https://github.com/webpack/webpack/pull/20916)) - Support no-expression template literals in computed member access (e.g. ``import.meta[`url`]``). (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20889](https://github.com/webpack/webpack/pull/20889)) - Improve tree-shaking in `isPure`: handle more expression types (`ArrayExpression`, `ObjectExpression`, `NewExpression`, `ChainExpression`, `UnaryExpression` (safe operators), `MetaProperty`, `TaggedTemplateExpression`, `BinaryExpression` (strict equality)), prevent `/*#__PURE__*/` comments from leaking across `ObjectExpression` properties, and detect PURE comments inside `TemplateLiteral` interpolations. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20723](https://github.com/webpack/webpack/pull/20723)) - Reject `new import.defer(...)` and `new import.source(...)` as a parse-time `SyntaxError`, matching the spec — `ImportCall` is a `CallExpression` and is not a valid operand of `new`. Parenthesized forms (`new (import.defer(...))`) remain valid and continue to throw `TypeError` at runtime as before. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20917](https://github.com/webpack/webpack/pull/20917)) - Escape `#` characters that appear inside a path-shaped request's directory portion before passing the request to the resolver, so projects located in directories like `/home/user/proj#1` (and tools like webpack-dev-server that build entry requests with query strings) resolve correctly. The escape only kicks in when the request contains both a `#` in the path portion and a `?` query string — paths without a query keep their existing semantics. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20980](https://github.com/webpack/webpack/pull/20980)) - Silence unhandled rejection from the prefetch trigger when chunk loading fails. The `ensureChunkHandlers.prefetch` runtime created `Promise.all(promises).then(...)` whose result is discarded by `__webpack_require__.e`. If chunk loading rejected (e.g. `chunkLoadTimeout`), that dangling chain produced an unhandled rejection. Prefetch is best-effort, so a no-op rejection handler is now attached. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20898](https://github.com/webpack/webpack/pull/20898)) - Align `require()` of an ES module with Node.js's [`require(esm)`](https://nodejs.org/docs/latest/api/modules.html#loading-ecmascript-modules-using-require) `"module.exports"` named-export convention. When CommonJS `require()` resolves to an ES module that exports a binding with the literal string name `"module.exports"` (e.g. `export { value as "module.exports" }`), `require()` now returns the value of that export instead of the module's namespace object — matching Node.js v22.12+/v23+ behavior and easing migration of dual ESM/CJS libraries that rely on `module.exports = …`. The unwrap applies to plain `require()`, `require().foo`, calls (`require()(…)`), destructuring, and to CJS wrappers like `module.exports = require(esm)` / `exports.x = require(esm)`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20981](https://github.com/webpack/webpack/pull/20981)) - Remove outdated `@types/eslint-scope` package from dependencies. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20869](https://github.com/webpack/webpack/pull/20869)) - Fix `export *` resolution when a star-reexported module re-exports a name back to the importer cyclically. Previously, in a graph where `a` does `export * from "./b"; export * from "./c";` and `b` does `export { foo } from "./a";` while `c` provides the actual `foo` binding, webpack hoisted `foo` from `b` into `a`'s namespace without per-name cycle detection — emitting a getter chain (`a.foo` → `b.foo` → `a.foo`) that threw "Maximum call stack size exceeded" at runtime. The TC39 `ResolveExport` algorithm requires the cyclic branch to return null and the star loop to fall through to the non-cyclic source. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20959](https://github.com/webpack/webpack/pull/20959)) - Preserve `using` declaration initializers when the inner graph optimization is enabled. (by [@&#8203;hai-x](https://github.com/hai-x) in [#&#8203;20906](https://github.com/webpack/webpack/pull/20906)) - Fixed typescript types. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20880](https://github.com/webpack/webpack/pull/20880)) - Bump `webpack-sources` to `^3.4.1` and feed asset bytes into hashes via the new `Source.prototype.buffers()` API. For large `ConcatSource`/`ReplaceSource` outputs this avoids the intermediate `Buffer.concat` that `source.buffer()` performs, removing a peak-memory spike equal to the source's total size on each hashed asset (`AssetGenerator.getFullContentHash`, `CssIcssExportDependency` content hashing, and `RealContentHashPlugin`). A small benchmark on a 64 MiB `ConcatSource` shows \~64 MiB lower peak external memory and \~45% faster hashing. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20897](https://github.com/webpack/webpack/pull/20897)) ### [`v5.106.2`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51062) [Compare Source](https://github.com/webpack/webpack/compare/v5.106.1...v5.106.2) ##### Patch Changes - CSS [@&#8203;import](https://github.com/import) now inherits the parent module's exportType, so a file configured as "text" correctly creates a style tag when [@&#8203;imported](https://github.com/imported) by a "style" parent. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20838](https://github.com/webpack/webpack/pull/20838)) - Make asset modules available in JS context when referenced from both CSS and a lazily compiled JS chunk. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20801](https://github.com/webpack/webpack/pull/20801)) - Include missing generator options in hash to ensure persistent cache invalidation when configuration changes (CssGenerator `exportsOnly`, JsonGenerator `JSONParse`, WebAssemblyGenerator `mangleImports`). (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20821](https://github.com/webpack/webpack/pull/20821)) - Fix `||` default value handling in ProgressPlugin and ManifestPlugin that incorrectly overrode user-provided falsy values (e.g. `modules: false`, `entries: false`, `entrypoints: false`). (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20823](https://github.com/webpack/webpack/pull/20823)) - Migrate from `mime-types` to `mime-db`. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20812](https://github.com/webpack/webpack/pull/20812)) - Handle `@charset` at-rules in CSS modules. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20831](https://github.com/webpack/webpack/pull/20831)) - Marked all experimental options in types. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20814](https://github.com/webpack/webpack/pull/20814)) ### [`v5.106.1`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51061) [Compare Source](https://github.com/webpack/webpack/compare/v5.106.0...v5.106.1) ##### Patch Changes - Fix two ES5-environment regressions in the anonymous default export `.name` fix-up: the generated code referenced an undeclared `__WEBPACK_DEFAULT_EXPORT__` binding causing `ReferenceError`, and used `Reflect.defineProperty` which is not available in pre-ES2015 runtimes. The fix-up now references the real assignment target and uses `Object.defineProperty` / `Object.getOwnPropertyDescriptor`. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20796](https://github.com/webpack/webpack/pull/20796)) - Prevent `!important` from being renamed as a local identifier in CSS modules. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20798](https://github.com/webpack/webpack/pull/20798)) - Use compiler context instead of module context for CSS modules local ident hashing to avoid hash collisions when files with the same name exist in different directories. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20799](https://github.com/webpack/webpack/pull/20799)) ### [`v5.106.0`](https://github.com/webpack/webpack/blob/HEAD/CHANGELOG.md#51060) [Compare Source](https://github.com/webpack/webpack/compare/v5.105.4...v5.106.0) ##### Minor Changes - Add `exportType: "style"` for CSS modules to inject styles into DOM via HTMLStyleElement, similar to style-loader functionality. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20579](https://github.com/webpack/webpack/pull/20579)) - Add `context` option support for VirtualUrlPlugin (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20449](https://github.com/webpack/webpack/pull/20449)) - The context for the virtual module. A string path. Defaults to 'auto', which will try to resolve the context from the module id. - Support custom context path for resolving relative imports in virtual modules - Add examples demonstrating context usage and filename customization - Generate different `CssModule` instances for different `exportType` values. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20590](https://github.com/webpack/webpack/pull/20590)) - Added the `localIdentHashFunction` option to configure the hash function to be used for hashing. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20694](https://github.com/webpack/webpack/pull/20694)) Additionally, the `localIdentName` option can now be a function. - Added support for destructuring assignment `require` in cjs, allowing for tree shaking. (by [@&#8203;ahabhgk](https://github.com/ahabhgk) in [#&#8203;20548](https://github.com/webpack/webpack/pull/20548)) - Added the `validate` option to enable/disable validation in webpack/plugins/loaders, also implemented API to make it inside plugins. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20275](https://github.com/webpack/webpack/pull/20275)) - Added `source` support for async WASM modules. (by [@&#8203;magic-akari](https://github.com/magic-akari) in [#&#8203;20364](https://github.com/webpack/webpack/pull/20364)) ##### Patch Changes - Add a static getSourceBasicTypes method to the Module class to prevent errors across multiple versions. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20614](https://github.com/webpack/webpack/pull/20614)) - Included fragment groups in the conflicting order warning for CSS. (by [@&#8203;aryanraj45](https://github.com/aryanraj45) in [#&#8203;20660](https://github.com/webpack/webpack/pull/20660)) - Avoid rendering unused top-level `__webpack_exports__` declaration when output ECMA module library.

(by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20771](https://github.com/webpack/webpack/pull/20771)) - Allow external modules place in async chunks when output ECMA module. (by [@&#8203;hai-x](https://github.com/hai-x) in [#&#8203;20662](https://github.com/webpack/webpack/pull/20662)) - Implement `deprecate` flag in schema for better TypeScript support to show which options are already deprecated by the configuration (by [@&#8203;bjohansebas](https://github.com/bjohansebas) in [#&#8203;20432](https://github.com/webpack/webpack/pull/20432)) - Set `.name` to `"default"` for anonymous default export functions and classes per ES spec (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20773](https://github.com/webpack/webpack/pull/20773)) - Hash entry chunks after runtime chunks to prevent stale content hash references in watch mode (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20724](https://github.com/webpack/webpack/pull/20724)) - Fix multiple bugs and optimizations in CSS modules: correct third code point position in walkCssTokens number detection, fix multiline CSS comment regex, fix swapped :import/:export error message, fix comma callback incorrectly popping balanced stack, fix cache comparison missing array length check, fix match.index mutation side effect, move publicPathAutoRegex to module scope, precompute merged callbacks in consumeUntil, simplify redundant ternary in CssGenerator, fix typo GRID_TEMPLATE_ARES, remove duplicate grid-column-start, and merge duplicate getCompilationHooks calls.

(by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20646](https://github.com/webpack/webpack/pull/20646)) - `import.meta` as standalone expression now returns a complete object with known properties (`url`, `webpack`, `main`, `env`) instead of an empty object `({})`, and hoists it as a module-level variable to ensure `import.meta === import.meta` identity. In `preserve-unknown` mode (ESM output), the hoisted object merges runtime `import.meta` properties via `Object.assign`. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20658](https://github.com/webpack/webpack/pull/20658)) - Fix incorrect condition in FileSystemInfo that always evaluated to false, preventing trailing slash removal from directory paths during build dependency resolution. (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20649](https://github.com/webpack/webpack/pull/20649)) - fix: VirtualUrlPlugin absolute path virtual module IDs getting concatenated with compiler context (by [@&#8203;xiaoxiaojx](https://github.com/xiaoxiaojx) in [#&#8203;20656](https://github.com/webpack/webpack/pull/20656)) When a virtual module ID is an absolute path (e.g. `virtual:C:/project/user.js`), the auto-derived context was incorrectly joined with `compiler.context`, producing a concatenated path like `C:\cwd\C:\project`. Now absolute-path contexts are used directly. - All deprecated methods and options now have `@deprecated` flag in types. (by [@&#8203;alexander-akait](https://github.com/alexander-akait) in [#&#8203;20707](https://github.com/webpack/webpack/pull/20707)) - Fix `CompatibilityPlugin` to correctly rename `__webpack_require__` when it appears as an arrow function parameter (e.g. `(__webpack_module, __webpack_exports, __webpack_require__) => { ... }`).
