Bump webpack from 5.99.9 to 5.107.1 in /frontend/webcoder_ui

[dependabot]

Bumps webpack from 5.99.9 to 5.107.1.

Release notes

Sourced from webpack's releases.

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 ≂̸) 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)

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 @​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.
