Compare Source

Notes

• using ~ is deprecated when the esModules option is enabled (enabled by default) and can be removed from your code (we recommend it) (url(~package/image.png) -> url(package/image.png), @import url(~package/style.css) -> @import url(package/style.css), composes: import from '~package/one.css'; -> composes: import from 'package/one.css';), but we still support it for historical reasons. Why can you remove it? The loader will first try to resolve @import/url()/etc as relative, if it cannot be resolved, the loader will try to resolve @import/url()/etc inside node_modules or modules directories.
• file-loader and url-loader are deprecated, please migrate on asset modules, since v6 css-loader is generating new URL(...) syntax, it enables by default built-in assets modules, i.e. type: 'asset' for all url()

⚠ BREAKING CHANGES

• minimum supported Node.js version is 12.13.0
• minimum supported webpack version is 5, we recommend to update to the latest version for better performance
• for url and import options Function type was removed in favor Object type with the filter property, i.e. before { url: () => true }, now { url: { filter: () => true } } and before { import: () => true }, now { import: { filter: () => true } }
• the modules.compileType option was removed in favor the modules.mode option with icss value, also the modules option can have icss string value
• new URL() syntax used for url(), only when the esModules option is enabled (enabled by default), it means you can bundle CSS for libraries
• data URI are handling in url(), it means you can register loaders for them, example
• aliases with false value for url() now generate empty data URI (i.e. data:0,), only when the esModules option is enabled (enabled by default)
• [ext] placeholder don't need . (dot) before for the localIdentName option, i.e. please change .[ext] on [ext] (no dot before)
• [folder] placeholder was removed without replacement for the localIdentName option, please use a custom function if you need complex logic
• [emoji] placeholder was removed without replacement for the localIdentName option, please use a custom function if you need complex logic
• the localIdentHashPrefix was removed in favor the localIdentHashSalt option

Features

• supported resolve.byDependency.css resolve options for @import
• supported resolve.byDependency.icss resolve CSS modules and ICSS imports (i.e. composes/etc)
• added modules.localIdentHashFunction, modules.localIdentHashDigest, modules.localIdentHashDigestLength options for better class hashing controlling
• less dependencies

Bug Fixes

• better performance
• fixed circular @import

Notes

• we strongly recommend not to add .css to resolve.extensions, it reduces performance and in most cases it is simply not necessary, alternative you can set resolve options by dependency
