[dependabot[bot]]

Bumps webpacker from 5.4.3 to 5.4.4.

Changelog

Sourced from webpacker's changelog.

Please note that Webpacker 3.1.0 and 3.1.1 have some serious bugs so please consider using either 3.0.2 or 3.2.0

Please note that Webpacker 4.1.0 has an installer bug. Please use 4.2.0 or above

[6.0.0] - 2021-TBD

Please see UPGRADE GUIDE for more information.

• node_modules will no longer be compiled by default. This primarily fixes [rails issue #35501](rails/rails#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/.

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
