Changes

JS API

This release includes an entirely new JavaScript API, designed to be more idiomatic, performant, and usable. The old API will continue to be supported until Dart Sass 2.0.0, but it is now considered deprecated and should be avoided for new code.

The new API includes:

  • compile() and compileAsync() functions that take Sass file paths and return the result of compiling them to CSS. The async function returns a Promise rather than using a callback-based API.

  • compileString() and compileStringAsync() functions that take a string of Sass source and compiles it to CSS. As above, the async function returns a Promise.

  • A new importer API that more closely matches the Sass specification's logic for resolving loads. This makes it much easier for Sass to cache information across @import and @use rules, which substantially improves performance for applications that rely heavily on repeated @imports.

  • A new custom function API, including much more usable JS representations of Sass value types complete with type-assertion functions, easy map and list lookups, and compatibility with the immutable package. Unlike in the legacy API, function callbacks now take one argument which contains an array of Sass values (rather than taking a separate JS argument for each Sass argument).

For full documentation of this API, please see the Sass website.
