`v4.26.0`

Compare Source

Features

Switch from uglify-es to terser as default minimizer

Note: While they are officially backward-compatible, it can still happen that a new bugs occurs with terser, which break your production builds. 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 configuration option to switch back to uglify-es or provide additional minimize options for terser.

Big changes

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 expor
