@skyscanner/backpack-react-scripts v11.2.2

backpack-react-scripts

Important: The currently supported version of CRA by backpack-react-scripts is up to v5+. Versions above this may not work.

This package is a fork of Create React App (specifically the react-scripts package). It's intended to be used in conjuction with create-react-app like so:

npx create-react-app my-app --scripts-version=@skyscanner/backpack-react-scripts --template @skyscanner/backpack --use-npm

# start your app development like you normally would with `create-react-app`
cd my-app
npm start

What is different in our fork?

• Compilation of uncompiled Backpack components (specifically JSX).
• Skyscanner specific template with Backpack components integrated out of the box. Published as @skyscanner/cra-template-backpack
• CSS Modules enabled by default for all .css & .scss files.
• Ability to create a bundle for server side rending.
• Automatic chunking is disabled by default.
• css.html & js.html: New files in the build/ output folder. These are html partials that include <script /> and <link /> references to the various static assets output by webpack. Useful if automatic chunking is turned on and you don't want to worry about order.
• A bunch of configuration options via "backpack-react-scripts" field in package.json:
  • crossOriginLoading: Modify the default behaviour, see docs.
  • babelIncludePrefixes: An array of module name prefixes to opt into babel compilation. Includes ["@skyscanner/bpk-", "bpk-"] by default.
  • enableAutomaticChunking: Boolean, opt in to automatic chunking of vendor, common and app code.
  • vendorsChunkRegex: String, Regex for picking what goes into the vendors chunk. See cacheGroups in webpack docs. Dependent on enableAutomaticChunking being enabled
  • amdExcludes: Array of module names to exclude from AMD parsing. Incldues ["lodash"] by default.
  • externals: exposing the Webpack config to modify externals, see docs.
  • ssrExternals: Similar to above, but for ssr.js only.
  • cssModules: Boolean, true by default.
  • sriEnabled: Sets if SRI is to be used during build to add integrity hash for files, see docs.
    • Note if this is enabled, crossOriginLoading value is overriden with anonymous in order for it to output with the integrity value.
  • ignoreCssWarnings: Boolean, false by default. Allows the ability to supress CSS ordering issues when its safe to allow mixed order when it has not effect on output, see docs. False by default
