  • v5.0.0-alpha.23 Changes

    August 27, 2019

    🚀 (based on 4.39.3)

    🔋 Features

    • ➕ add option output.ecmaVersion to specify level of generated code emitted by webpack
      • By using arrow functions we can emit smaller code, i. e. for exports
      • By using const variables we can emit more correct code for export default

    🔄 Changes

    • 0️⃣ (BREAKING) changed default of output.ecmaVersion from implict 5 to 2015
      • This might be incompatible with some older browser.
      • If you need support for these browser use output.ecmaVersion: 5.

  • v5.0.0-alpha.21 Changes

    August 22, 2019

    🚀 (based on 4.39.2)

    🔋 Features

    • ⬆️ Upgrade to acorn 7
    • Persistent Caching
      • track dependencies while resolving build dependencies to snapshot them
      • when build dependencies resolving snapshot is invalid, re-resolve build dependencies to see if something changed
      • new option cache.immutablePaths, similar to cache.managedPaths but assumes that existing content of this folder never changes. Defaults to yarn cache when PnP is used.
      • cache.cacheDirectory defaults to node_modules/.cache/webpack when package.json exists somewhere above cwd, .pnp/.cache/webpack when .pnp.js exists, .cache/webpack otherwise.
    • add __webpack_exports_info__ module API

    🛠 Bugfixes

    • 🛠 fix a bug where external default imports in concatenated modules where incorrectly generated
    • 👌 improve usage/provision info for nested exports

  • v5.0.0-alpha.20 Changes

    August 14, 2019

    🚀 (based on 4.39.2)

    🐎 Performance

    • Compilation/NormalModuleFactory.file/context/missingDependencies are now LazySets
    • 🐎 Performance improvements in deserialization
    • 🐎 Performance improvements in module graph building

    🔋 Features

    • ➕ add cache.managedPaths. It is an array of package-manager only managed paths. webpack will avoid hashing/timestamping them, assume the version is unique and will use this as snapshot (for both memory and filesystem cache).
      • These must be node_modules directories.
      • cache.managedPaths defaults to the node_modules directory webpack is inside of.
    • ➕ add cache.buildDependencies. It is an object of arrays of additional code dependencies of the build. webpack will use an hash of these items and all dependencies to invalidate the filesystem cache.
      • cache.buildDependencies.defaultWebpack defaults to webpack/lib to get webpack and all dependencies.
      • It's recommended to set cache.buildDependencies.config: [__filename] in webpack.config.js to get the config and all dependencies.

    🔄 Changes

    • 👉 Use [email protected] for schema validation
    • 🌲 Persistent Caching uses the infrastructureLogger for logging

    Removals

    • ✂ remove cache.loglevel
      • Use infrastructureLogging.level instead

      • add experiments.syncWebAssembly
      • add experiments.asyncWebAssembly
    • ➕ add asset module type experiment
      • add experiments.asset

      • auxiliary files are displayed in brackets in Stats
    • 🔌 Some core implementations and plugins do some time and statistics logging now (try stats.loggingDebug: /webpack/)
    • ➕ add Compilation.hooks.stillValidModule similar to failedModule and succeedModule when a module has been taken from cache

    🛠 Bugfixes
