See [here for the webpack issue](https://togithub.com/webpack/webpack/issues/8656). The [npm bug](https://npm.community/t/packages-with-peerdependencies-are-incorrectly-hoisted/4794) has [been fixed](https://togithub.com/npm/cli/pull/147), but a new npm version has not been released yet. For workarounds see [this comment](https://togithub.com/webpack/webpack/issues/8656#issuecomment-456713191). Eventually the fix will be to upgrade npm once the bugfix is released. ### Features - update acorn to v6 - limit the number of in parallel written output files to 15 - add `output.futureEmitAssets` which gives the emitting logic of webpack 5 - assets are replaced with SizeOnlySources - reading assets after emitting is no longer allowed - This allows memory to be garbage-collected ### [`v4.28.4`](https://togithub.com/webpack/webpack/releases/v4.28.4) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.3...v4.28.4) ### Bugfixes - `ProfilingPlugin` creates output path if not existing - fixed support for arrow function functions for `optimization.minimizer` - failed hooks is now also called when `run()` fails ### [`v4.28.3`](https://togithub.com/webpack/webpack/releases/v4.28.3) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.2...v4.28.3) ### Bugfixes - ProfilingPlugin creates the output folder if necessary ### [`v4.28.2`](https://togithub.com/webpack/webpack/releases/v4.28.2) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.1...v4.28.2) ### Bugfixes - fixes a crash when multiple IgnorePlugins are used ### [`v4.28.1`](https://togithub.com/webpack/webpack/releases/v4.28.1) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.0...v4.28.1) ### Bugfixes - fix error in IgnorePlugin when no contextRegExp is passed ### [`v4.28.0`](https://togithub.com/webpack/webpack/releases/v4.28.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.27.1...v4.28.0) ### Features - IgnorePlugin: `checkResource` has an additional `context` argument ### Bugfixes - Injection of node.js globals has been disabled for `.mjs` files as it's crashing ### [`v4.27.1`](https://togithub.com/webpack/webpack/releases/v4.27.1) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.27.0...v4.27.1) ### Bugfixes - v4.27.0 accidentially introduced a breaking change.

Make sure to validate your production builds after upgrading to this version. (Note that it's always a good idea to test your output assets before deploying.) If you want to report bugs to terser (https://github.com/terser-js/terser), please provide a minimal repro case with minimized and **non-minimized** code. You can configure webpack to generate non-minimized code in production mode by setting `optimization.minimize: false`. When reporting a bug to terser, best report a repro case which doesn't require running webpack and is reproducible with only the terser command line. See [`optimization.minimizers`](https://webpack.js.org/configuration/optimization/#optimization-minimizer) configuration option to switch back to uglify-es or provide additional minimize options for terser. ### [`v4.25.1`](https://togithub.com/webpack/webpack/releases/v4.25.1) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.25.0...v4.25.1) ### Bugfixes -

Environment - Node.js 4 is no longer supported. Source Code was upgraded to a higher ecmascript version. - Usage - You have to choose (`mode` or `--mode`) between two modes now: production or development - production enables all kind of optimizations to generate optimized bundles - development enables comments and hint for development and enables the eval devtool - production doesn't support watching, development is optimized for fast incremental rebuilds - production also enables module concatenating (Scope Hoisting) - You can configure this in detail with the flags in `optimization.*` (build your custom mode) - `process.env.NODE_ENV` are set to production or development (only in built code, not in config) - There is a hidden `none` mode which disables everything - Syntax - `import()` always returns a namespace object. CommonJS modules are wrapped into the default export - This probably breaks your code, if you used to import CommonJs with `import()` - Configuration - You no longer need to use these plugins: - `NoEmitOnErrorsPlugin` -> `optimization.noEmitOnErrors` (on by default in production mode) - `ModuleConcatenationPlugin` -> `optimization.concatenateModules` (on by default in production mode) - `NamedModulesPlugin` -> `optimization.namedModules` (on by default in develoment mode) - `CommonsChunkPlugin` was removed -> `optimization.splitChunks`, `optimization.runtimeChunk` - JSON - webpack now handles JSON natively - You may need to add `type: "javascript/auto"` when transforming JSON via loader to JS - Just using JSON without loader should still work - allows to import JSON via ESM syntax - unused exports elimination for JSON modules - Optimization - Upgrade uglifyjs-webpack-plugin to v1 - ES15 support ##### Big features - Modules - webpack now supports these module types: - javascript/auto: (The default one in webpack 3) Javascript module with all module systems enabled: CommonJS, AMD, ESM - javascript/esm: EcmaScript modules, all other module system are not available - javascript/dynamic: Only CommonJS and, EcmaScript modules are not available - json: JSON data, it's available via require and import - webassembly/experimental: WebAssembly modules (currently experimental) - `javascript/esm` handles ESM more strictly compared to `javascript/auto`: - Imported names need to exist on imported module - Dynamic modules (non-esm, i. e. CommonJs) can only imported via `default` import, everything else (including namespace import) emit errors - In `.mjs` modules are `javascript/esm` by default - WebAssembly modules - can import other modules (JS and WASM) - Exports from WebAssembly modules are validated by ESM import - You'll get a warning/error when trying to import a non-existing export from WASM - can only be used in async chunks. They doesn't work in initial chunks (would be bad for web performance) - Import modules using WASM via `import()` - This is an experimental feature and subject of change - Optimization - `sideEffects: false` is now supported in package.json - `sideEffects` in package.json also supports glob expressions and arrays of glob expressions - Instead of a JSONP function a JSONP array is used -> async script tag support, order no longer matter - New `optimization.splitChunks` option was introduced Details: https://gist.github.com/sokra/1522d586b8e5c0f5072d7565c2bee693 - Dead branches are now removed by webpack itself - Before: Uglify removed the dead code - Now: webpack removes the dead code (in some cases) - This prevents crashing when `import()` occur in a dead branch - Syntax - `webpackInclude` and `webpackExclude` are supported by the magic comment for `import()`. They allow to filter files when using a dynamic expression. - Using `System.import()` now emits a warning - You can disable the warning with `Rule.parser.system: true` - You can disable `System.import` with `Rule.parser.system: false` - Configuration - Resolving can now be configured with `module.rules[].resolve`. It's merged with the global configuration. - `optimization.minimize` has been added to switch minimizing on/off - By default: on in production mode, off in development mode - `optimization.minimizer` has been added to configurate minimizers and options - Usage - Some Plugin options are now validated - CLI has been move to webpack-cli, you need to install `webpack-cli` to use the CLI - The ProgressPlugin (`--progress`) now displays plugin names - At least for plugins migrated to the new plugin system - Performance - UglifyJs now caches and parallizes by default - Multiple performance improvements, especially for faster incremental rebuilds - performance improvement for RemoveParentModulesPlugin - Stats - Stats can display modules nested in concatenated modules ##### Features - Configuration - Module type is automatically choosen for mjs, json and wasm extensions. Other extensions need to be configured via `module.rules[].type` - Incorrect `options.dependencies` configurations now throw error - `sideEffects` can be overriden via module.rules - `output.hashFunction` can now be a Constructor to a custom hash function - You can provide a non-cryto hash function for performance reasons - add `output.globalObject` config option to allow to choose the global object reference in runtime exitCode - Runtime - Error for chunk loading now includes more information and two new properties `type` and `request`. - Devtool - remove comment footer from SourceMaps and eval - add support for `include` `test` and `exclude` to the eval source map devtool plugin - Performance - webpacks AST can be passed directly from loader to webpack to avoid extra parsing - Unused modules are no longer unnecessarly concatenated - Add a ProfilingPlugin which write a (Chrome) profile file which includes timings of plugins - Migrate to using `for of` instead of `forEach` - Migrate to using `Map` and `Set` instead of Objects - Migrate to using `includes` instead of `indexOf` - Replaced some RegExp with string methods - Queue don't enqueues the same job twice - Use faster md4 hash for hashing by default - Optimization - When using more than 25 exports mangled export names are shorter. - script tags are no longer `text/javascript` and `async` as this are the default values (saves a few bytes) - The concatenated module now generates a bit less code - constant replacements now don't need `__webpack_require__` and argument is omitted - Defaults - webpack now looks for the `.wasm`, `.mjs`, `.js` and `.json` extensions in this order - `output.pathinfo` is now on by default in develoment mode - in-memory caching is now off by default in production - `entry` defaults to `./src` - `output.path` defaults to `./dist` - Use `production` defaults when omiting the `mode` option - Usage - Add detailed progress reporting to SourceMapDevToolPlugin - removed plugins now give a useful error message - Stats - Sizes are now shown in kiB instead of kB in Stats - entrypoints are now shows by default in Stats - chunks now display `<{parents}>` `>{children}<` and `={siblings}=` in Stats - add `buildAt` time to stats - stats json now includes the output path - Syntax - A resource query is supported in context - Referencing entry point name in `import()` now emits a error instead of a warning - Upgraded to acorn 5 and support ES 2018 - Plugins - `done` is now an async hook ##### Bugfixes - Generated comments no longer break on `*/` - webpack no longer modifies the passed options object - Compiler "watch-run" hook now has the Compiler as first parameter - add `output.chunkCallbackName` to the schema to allow configurating WebWorker template - Using `module.id/loaded` now correctly bails out of Module Concatentation (Scope Hoisting) - OccurenceOrderPlugin now sorts modules in correct order (instead of reversed) - timestamps for files are read from watcher when calling `Watching.invalidate` - fix incorrect `-!` behavior with post loaders - add `run` and `watchRun` hooks for `MultiCompiler` - `this` is now undefined in ESM - VariableDeclaration are correctly identified as `var`, `const` or `let` - Parser now parse the source code with the correct source type (module/script) when the module type `javascript/dynamic` or `javascript/module` is used. - don't crash on missing modules with `buildMeta` of null - add `original-fs` module for electron targets - HMRPlugin can be added to the Compiler outside of `plugins` ##### Internal changes - Replaced `plugin` calls with `tap` calls (new plugin system) - Migrated many deprecated plugins to new plugin system API - added `buildMeta.exportsType: "default"` for json modules - Remove unused methods from Parser (parserStringArray, parserCalculatedStringArray) - Remove ability to clear BasicEvaluatedExpression and to have multiple types - Buffer.from instead of new Buffer - Avoid using forEach and use for of instead - Use `neo-async` instead of `async` - Update tapable and enhanced-resolve dependencies to new major versions - Use prettier ##### Removed features - removed `module.loaders` - r
