Release notes

Sourced from postcss's releases.

8.3 “Duke Murmur”

Thanks to Sponsors

This release was possible thanks to our community.

Source Map Performance

Because PostCSS needs synchronous API, we can’t move from the old `source-map 0.6 to 0.7 (many other open-source projects too).

@​7rulnik forked source-map 0.6 to source-map-js and back-ported performance improvements from 0.7. In 8.3 we switched from source-map to this source-map-js fork.

You map see 4x performance improvements in parsing map from processing step before PostCSS (for instance, Sass).

Document Nodes

Thanks to @​gucong3000, PostCSS already parse CSS from HTML and JS files (CSS-in-JS templates and objects).

But his plugin need big updates. @​hudochenkov from stylelint team decided to create new parsers for styles inside CSS-in-JS, HTML, and Markdown.

He suggested adding new Document node type to PostCSS AST to keep multiple Root nodes inside and JS/HTML/Markdown code blocks between these style blocks.

const document = htmlParser(
  '<html><style>a{color:black}</style><style>b{z-index:2}</style>'
)
document.type          //=> 'document'
document.nodes.length  //=> 2
document.nodes[0].type //=> 'root'

This is an experimental feature. Some aspects of this node could change within minor or patch version releases.

Node#assign() Shortcut
