PostCSS is a JavaScript framework for transforming CSS via a plugin ecosystem, parsing stylesheets into an AST that plugins can analyze and modify. It powers popular tools like Autoprefixer, Stylelint, and CSS Modules, and is used by Wikipedia, Twitter, and JetBrains.
Use cases
- add vendor prefixes to css automatically
- transpile modern css syntax for older browsers
- lint stylesheets for errors and conventions
- scope css class names with css modules
- write custom css transformations as js plugins
- minify css for production
When to choose
- you need programmatic CSS transformation in a JS build pipeline
- you want vendor prefixing, future CSS syntax, or CSS linting
- you are building custom CSS tooling or plugins
When to avoid
- you only need a full CSS framework with prebuilt components
- your project does not use a JavaScript build step
- you prefer Sass/Less-style preprocessing without a plugin pipeline
