Top 4 JavaScript W3c Projects

csstree

1 1,836 7.1 JavaScript

A tool set for CSS including fast detailed parser, walker, generator and lexer based on W3C specs and browser implementations

Project mention: Building a lightweight CSS formatter | dev.to | 2023-06-12

After thinking about the problem for a while I realised that I could enlist the help of CSSTree to do some of the work. The CSS Analyzer is based on CSSTree's AST, so I know how the thing works and the dependency is already on the page, so no need to download more dependencies. Prettier + Postcss cost almost 340kB to download, which isn't huge, but it would be nice if we could reduce that amount.

Project mention: Language for controlling mouse output? | /r/learnprogramming | 2023-05-25
