v6.0.0-alpha.0

Add webpack 5 support.

Changelog

Sourced from laravel-mix's changelog.

Changelog

6.0.14

• BabelConfig.fetchBabelRc / static BabelConfig.default / static BabelConfig.generate have all been deprecated. They are no longer used by Mix itself but remain for backwards compatability.
• MixDefinitionsPlugin.getDefinitions and static MixDefinitionsPlugin.build have been deprecated. They are no longer used by Mix itself but remain for backwards compatability.
• static Chunks._instance / static Chunks.instance() / static Chunks.reset() are now deprecated and will be removed in a future release.
• The static methods on HotReloading are now deprecated. They have been replaced with instance methods.
• The use of the globals Mix, Config, and webpackConfig are now deprecated and will warn on use in Mix v7.

We are working toward an API for access to Mix for extensions that does not assume that it is a global or that it is the same instance in all cases.

In the mean time:

• Uses of Chunks.instance() may be replaced with Mix.chunks
• Uses of Config may be replaced with Mix.config
• Uses of webpackConfig may be replaced with Mix.webpackConfig
• Uses of HotReloading.* methods Mix.hot.*

Review Your Dependencies

Laravel Mix 6 ships with support for the latest versions of numerous dependencies, including webpack 5, PostCSS 8, Vue Loader 16, and more. These are significant releases with their own sets of breaking changes. We've done our best to normalize these changes, but it's still particularly important that you take the time to fully test your build after upgrading to Mix 6.

Please review your package.json dependencies list for any third-party tools or plugins that may not yet be compatible with webpack 5 or PostCSS 8.

Check Your Node Version

Mix has bumped its minimum Node requirement from version 8 to 12.14.0. Please check which version you have installed (node -v) and ensure that it meets this requirement.

Update Your NPM Scripts

If your build throws an error such as Unknown argument: --hide-modules, the scripts section of your package.json file will need to be updated. The Webpack 5 CLI removed a number of options that your NPM scripts was likely referencing.

While you're at it, go ahead and switch over to the new Mix CLI.

Before

"scripts": {
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "npm run development -- --watch",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --disable-host-check --config=node_modules/laravel-mix/setup/webpack.config.js",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
}
