v6.2.0 - March 22, 2022

Added

• Make manifest_path configurable, to keep manifest.json private if desired. PR 78 by jdelStrother.
• Rewrite webpack module rules as regular expressions. Allows for easy iteration during config customization. PR 60 by blnoonan.
• Initialization check to ensure shakapacker gem and NPM package version are consistent. Opt-in behaviour enabled by setting ensure_consistent_versioning configuration variable. PR 51 by tomdracz.
• Add dev_server.inline_css: bool config option to allow for opting out of style-loader and into mini-extract-css-plugin for CSS HMR in development. PR 69 by cheald.

Improved

• Increase default connect timeout for dev server connections, establishing connections more reliably for busy machines. PR 74 by stevecrozz.
• Allow multiple invocations of stylesheet_pack_tag (eg for a regular stylesheet & a print stylesheet). PR 82 by jdelStrother.
• Tweak swc config for parity with Babel. PR 79 by dleavitt.

v6.1.1 - February 6, 2022

Added

• Support for esbuild-loader. PR 53 by tomdracz.

v6.1.0 - February 4, 2022

Added

• Support for SWC loader. PR 29 by tomdracz.

Fixed

• Static asset subdirectories are retained after compilation, matching Webpacker v5 behaviour. PR 47 by tomdracz. Fixes issues rails/webpacker#2956 which broke in rails/webpacker#2802.

v6.0.2 - January 25, 2022

Improved

• Fix incorrect command name in warning. PR 33 by tricknotes.

v6.0.1 - January 24, 2022

• PR #21 removed pnp-webpack-plugin as a dev dependency but did not remove it from the peer dependency list. PR 30 by t27duck.

v6.0.0 changes from v6.0.0.rc.6 - January 22, 2022

Improved

• Raise on multiple invocations of javascript_pack_tag and stylesheet_pack_tag helpers. PR 19 by tomdracz.
• Remove automatic addition of node_modules into rails asset load path. PR 20 by tomdracz.
• Remove pnp-webpack-plugin. PR 21 by tomdracz.

Merged from rails/webpacker

• Make watched_files_digest thread safe. rails/webpacker #3233
• Use single webpack config webpack.config.js. rails/webpacker #3240
• Switch to peer dependencies. rails/webpacker #3234

Upgrading from rails/webpacker 6.0.0.rc.6

• Single default configuration file of config/webpack/webpack.config.js. Previously, the config file was set to config/webpack/#{NODE_ENV}.js.
• Changed all package.json dependencies to peerDependencies, so upgrading requires adding the dependencies, per the UPGRADE GUIDE.

v6.0.0.rc.6 changes from v5.4 - Forked January 16, 2022

• node_modules will no longer be babel transfomed compiled by default. This primarily fixes rails issue #35501 as well as numerous other webpacker issues. The disabled loader can still be required explicitly via:

  const nodeModules = require('@rails/webpacker/rules/node_modules.js')
  environment.loaders.append('nodeModules', nodeModules)

• If you have added environment.loaders.delete('nodeModules') to your environment.js, this must be removed or you will receive an error (Item nodeModules not found).

• extract_css option was removed. Webpacker will generate a separate application.css file for the default application pack, as supported by multiple files per entry introduced in 5.0.0. #2608. However, CSS will be inlined when the webpack-dev-server is used with hmr: true. JS package exports inliningCss. This is useful to enable HMR for React.

• Webpacker's wrapper to the splitChunks() API will now default runtimeChunk: 'single' which will help prevent potential issues when using multiple entry points per page #2708.

• Changes @babel/preset-env modules option to 'auto' per recommendation in the Babel docs #2709

• Adds experimental Yarn 2 support. Note you must manually set nodeLinker: node-modules in your .yarnrc.yml.

• Fixes dev server issues #2898

• Update static files path to from media/ to static/.

• Deprecated configuration option watched_paths. Use additional_paths instead in webpacker.yml.

Breaking changes

• Renamed /bin/webpack to /bin/webpacker and /bin/webpack-dev-server to bin/webpacker-dev-server to avoid confusion with underlying webpack executables.
• Removed integration installers
• Splitchunks enabled by default
• CSS extraction enabled by default, except when devServer is configured and running
