Update webpack to the latest version 🚀 #106

Closed greenkeeper[bot] closed 5 years ago

greenkeeper[bot] commented 6 years ago

☝️ Greenkeeper’s updated Terms of Service will come into effect on April 6th, 2018.

Version 4.0.0 of webpack was just published.

Dependency	webpack
Current Version	3.11.0
Type	devDependency

The version 4.0.0 is not covered by your current version range.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

It might be worth looking into these changes and trying to get this project onto the latest version of webpack.

If you have a solid test suite and good coverage, a passing build is a strong indicator that you can take advantage of these changes directly by merging the proposed change into your project. If the build fails or you don’t have such unconditional trust in your tests, this branch is a great starting point for you to work on the update.

Release Notes

v4.0.0

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 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

- plugin method is backward-compatible
- Plugins should use Compiler.hooks.xxx.tap(<plugin name>, fn) now
New major version of enhanced-resolve

Chunk.chunks/parents/blocks are no longer Arrays. A Set is used internally and there are methods to access it.
Parser.scope.renames and Parser.scope.definitions are no longer Objects/Arrays, but Map/Sets.
Parser uses StackedSetMap (LevelDB-like datastructure) instead of Arrays
Compiler.options is no longer set while applying plugins
Harmony Dependencies has changed because of refactoring
Dependency.getReference() may now return a weak property. Dependency.weak is now used by the Dependency base class and returned in the base impl of getReference()
Constructor arguments changed for all Modules

- Before: AsyncDependenciesBlocks reference a list of Chunks in order.
- Now: AsyncDependenciesBlocks reference a single ChunkGroup.
file/contextTimestamps are Maps now
map/foreach Chunks/Modules/Parents methods are now deprecated/removed
NormalModule accept options object in Constructor
Added required generator argument for NormalModule
