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 ≂̸) 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)
