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)

Patch Changes

• CSS @​import now inherits the parent module's exportType, so a file configured as "text" correctly creates a style tag when @​imported by a "style" parent. (by @​xiaoxiaojx in #​20838)

• Make asset modules available in JS context when referenced from both CSS and a lazily compiled JS chunk. (by @​xiaoxiaojx in #​20801)

• Include missing generator options in hash to ensure persistent cache invalidation when configuration changes (CssGenerator exportsOnly, JsonGenerator JSONParse, WebAssemblyGenerator mangleImports). (by @​xiaoxiaojx in #​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 @​xiaoxiaojx in #​20823)

• Migrate from mime-types to mime-db. (by @​alexander-akait in #​20812)

• Handle @charset at-rules in CSS modules. (by @​alexander-akait in #​20831)

• Marked all experimental options in types. (by @​alexander-akait in #​20814)

v5.106.1

Compare Source

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)

Minor Changes

• Add exportType: "style" for CSS modules to inject styles into DOM via HTMLStyleElement, similar to style-loader functionality. (by @​xiaoxiaojx in #​20579)

• 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)

• Added the validate option to enable/disable validation in webpack/plugins/loaders, also implemented API to make it inside plugins. (by @​xiaoxiaojx in #​20275)

• Added source support for async WASM modules. (by @​magic-akari in #​20364)

Patch Changes

• Add a static getSourceBasicTypes method to the Module class to prevent errors across multiple versions. (by @​xiaoxiaojx in #​20614)

• Included fragment groups in the conflicting order warning for CSS. (by @​aryanraj45 in #​20660)

• Avoid rendering unused top-level __webpack_exports__ declaration when output ECMA module library. (by @​hai-x in #​20669)

• Fixed resolving in CSS modules. (by @​alexander-akait in #​20771)

• Allow external modules place in async chunks when output ECMA module. (by @​hai-x in #​20662)

• Implement deprecate flag in schema for better TypeScript support to show which options are already deprecated by the configuration (by @​bjohansebas in #​20432)

• Set .name to "default" for anonymous default export functions and classes per ES spec (by @​xiaoxiaojx in #​20773)

• 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. (by @​xiaoxiaojx in #​20648)

• 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)

• Fix CompatibilityPlugin to correctly rename __webpack_require__ when it appears as an arrow function parameter (e.g. (__webpack_module, __webpack_exports, __webpack_require__) => { ... }). (by @​hai-x in #​20661)

Patch Changes

• Context modules now handle rejections correctly. (by @​alexander-akait in #​20455)

• Only mark asset modules as side-effect-free when experimental.futureDefaults is set to true, so asset-copying use cases (e.g. import "./x.png") won’t break unless the option is enabled. (by @​hai-x in #​20535)

• Add the missing webpack_exports declaration in certain cases when bundling a JS entry together with non-JS entries (e.g., CSS entry or asset module entry). (by @​hai-x in #​20463)

• Fixed HMR failure for CSS modules with @​import when exportType !== "link". When exportType is not "link", CSS modules now behave like JavaScript modules and don't require special HMR handling, allowing @​import CSS to work correctly during hot module replacement. (by @​xiaoxiaojx in #​20514)

• Fixed an issue where empty JavaScript files were generated for CSS-only entry points. The code now correctly checks if entry modules have JavaScript source types before determining whether to generate a JS file. (by @​xiaoxiaojx in #​20454)

• Do not crash when a referenced chunk is not a runtime chunk. (by @​alexander-akait in #​20461)

• Fix some types. (by @​alexander-akait in #​20412)

• Ensure that missing module error are thrown after the interception handler (if present), allowing module interception to customize the module factory. (by @​hai-x in #​20510)

• Added createRequire support for ECMA modules. (by @​stefanbinoj in #​20497)

• Added category for CJS reexport dependency to fix issues with ECMA modules. (by @​hai-x in #​20444)

• Implement immutable bytes for bytes import attribute to match tc39 spec. (by @​alexander-akait in #​20481)

Patch Changes

• Fix VirtualUrlPlugin Windows compatibility by sanitizing cache keys and filenames. Cache keys now use toSafePath to replace colons (:) with double underscores (__) and sanitize other invalid characters, ensuring compatibility with Windows filesystem restrictions. (by @​xiaoxiaojx in #​20424)

• Revert part of the createRequire generation behavior for require("node:...") to keep compatibility with those modules exports, e.g. const EventEmitter = require("node:events");. (by @​hai-x in #​20433)

Minor Changes

• Allow resolving worker module by export condition name when using new Worker() (by @​hai-x in #​20353)

• Detect conditional imports to avoid compile-time linking errors for non-existent exports. (by @​hai-x in #​20320)

• Added the tsconfig option for the resolver options (replacement for tsconfig-paths-webpack-plugin). Can be false (disabled), true (use the default tsconfig.json file to search for it), a string path to tsconfig.json, or an object with configFile and references options. (by @​alexander-akait in #​20400)

• Support import.defer() for context modules. (by @​ahabhgk in #​20399)

• Added support for array values ​​to the devtool option. (by @​hai-x in #​20191)

• Improve rendering node built-in modules for ECMA module output. (by @​hai-x in #​20255)

• Unknown import.meta properties are now determined at runtime instead of being statically analyzed at compile time. (by @​xiaoxiaojx in #​20312)

Patch Changes

• Fixed ESM default export handling for .mjs files in Module Federation (by @​y-okt in #​20189)

• Optimized import.meta.env handling in destructuring assignments by using cached stringified environment definitions. (by @​xiaoxiaojx in #​20313)

• Respect the stats.errorStack option in stats output. (by @​samarthsinh2660 in #​20258)

• Fixed a bug where declaring a module variable in module scope would conflict with the default moduleArgument. (by @​xiaoxiaojx in #​20265)

• Fix VirtualUrlPlugin to set resourceData.context for proper module resolution. Previously, when context was not set, it would fallback to the virtual scheme path (e.g., virtual:routes), which is not a valid filesystem path, causing subsequent resolve operations to fail. (by @​xiaoxiaojx in #​20390)

• Fixed Worker self-import handling to support various URL patterns (e.g., import.meta.url, new URL(import.meta.url), new URL(import.meta.url, import.meta.url), new URL("./index.js", import.meta.url)). Workers that resolve to the same module are now properly deduplicated, regardless of the URL syntax used. (by @​xiaoxiaojx in #​20381)

• Reuse the same async entrypoint for the same Worker URL within a module to avoid circular dependency warnings when multiple Workers reference the same resource. (by @​xiaoxiaojx in #​20345)

• Fixed a bug where a self-referencing dependency would have an unused export name when imported inside a web worker. (by @​samarthsinh2660 in #​20251)

• Fix missing export generation when concatenated modules in different chunks share the same runtime in module library bundles. (by @​hai-x in #​20346)

• Fixed import.meta.env.xxx behavior: when accessing a non-existent property, it now returns empty object instead of full object at runtime. (by @​xiaoxiaojx in #​20289)

• Improved parsing error reporting by adding a link to the loader documentation. (by @​gaurav10gg in #​20244)

• Fix typescript types. (by @​alexander-akait in #​20305)

• Add declaration for unused harmony import specifier. (by @​hai-x in #​20286)

• Fix compressibility of modules while retaining portability. (by @​dmichon-msft in #​20287)

• Optimize source map generation: only include ignoreList property when it has content, avoiding empty arrays in source maps. (by @​xiaoxiaojx in #​20319)

• Preserve star exports for dependencies in ECMA module output. (by @​hai-x in #​20293)

• Consider asset modulem to be side-effect free. (by @​hai-x in #​20352)

• Avoid generating JavaScript modules for CSS exports that are not used, reducing unnecessary output and bundle size. (by @​xiaoxiaojx in #​20337)
