Release Notes

5.109.2

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)

• Report "universal" as the loader context target for the universal target. (by @alexander-akait in #21540)

• Skip require().prop in dead branches gated by inlined imported constants. (by @hai-x in #21517)

• Annotate configuration options and public hooks in the generated types with the @since JSDoc tag. (by @bjohansebas in #21473)

5.109.1

Patch Changes

• Fix stray semicolon emitted before an imported call following a parenthesized sequence element. (by @alexander-akait in #21533)

• 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)

• Rename nested const/let __webpack_require__ and __webpack_exports__ declarations in bundled webpack output. (by @hai-x in #21508)

5.109.0

• Add output.html.manifest to generate and link a web app manifest with hashed icons. (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 #21477)

• 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 #21477)

• Allow disabling a built-in HTML parser source via type: false in sources. (by @alexander-akait in #21477)

• Export webpack.html.HtmlModulesPlugin with transformHtml/htmlEmitted compilation hooks. (by @alexander-akait in #21477)

• Resolve @custom-media (including media-type values) and @custom-selector in native CSS. (by @alexander-akait in #21477)

• 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 #21477)

• Resolve import.meta.resolve("./asset") to the emitted asset URL via the importMeta.resolve parser option. (by @alexander-akait in #21477)

• Add fine-grained import.meta parser options. (by @alexander-akait in #21477)

• Deprecate the importMetaContext parser option in favor of importMeta.webpackContext. (by @alexander-akait in #21477)

• Emit analyzable new URL(…, import.meta.url), worker/worklet URL and import() references with literal specifiers for ESM module output. (by @alexander-akait in #21477)

• Compile async modules to generators for targets without async/await. (by @alexander-akait in #21477)

• Evaluate and validate the second argument of dynamic import(specifier, options). (by @alexander-akait in #21477)

• Warn on strict-mode-only syntax and semantic hazards in ES module output, configurable via the strictModeViolations parser option. (by @alexander-akait in #21477)

• Support parsers without location APIs: locations derive from node offsets and AST nodes no longer carry loc. (by @alexander-akait in #21477)

• Attach the original DOM event to ChunkLoadError and ScriptExternalLoadError as error.event. (by @alexander-akait in #21477)

• Add output.wasmStreamingFallback for wasm fallback on a wrong MIME type. (by @alexander-akait in #21477)

• Fix unused CSS module exports leaking into the JS wrapper. (by @alexander-akait in #21477)

• Keep required JSON data intact when a prototype method (e.g. arr.includes()) is called on it. (by @alexander-akait in #21477)

• Recognize modern RegExp flags (d, s, u, v) when statically evaluating new RegExp(...). (by @alexander-akait in #21477)

• Merge object-form and dotted DefinePlugin definitions so import.meta.env/process.env are consistent across direct, whole-object and destructured access. (by @alexander-akait in #21477)

• Emit an error when an object external has no entry for the used externals type. (by @alexander-akait in #21477)
