PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. ...

semantic-graph finds duplicate and related tests in your test suite. It scans Playwright-style test files written with test() and test.describe(), embeds each test, groups similar tests with DBSCAN clustering and names each cluster with an LLM. The results open in a local web UI with a folder tree and a 2D similarity graph laid out with UMAP, so overlapping tests are easy to spot. It is for developers and QA engineers who want to keep a growing suite lean and find tests that cover the...

SassDoc is to Sass what JSDoc is to JavaScript: a documentation system to build pretty and powerful docs in the blink of an eye. SassDoc parses your source folder to grab documentation-specific comments. From there, it builds a data tree, that gets enhanced and filtered before being passed to the view. So you end up with a fully styled HTML document. Write SassDoc-compliant comments. The syntax is pretty close to JSDoc’s although we took some liberty with it. SassDoc comes with surprisingly few configurations in itself. Most of the configuration is brought by the theme. ...

A tool for making JavaScript code run faster. Prepack is still in an early development stage and not ready for production use just yet. Please try it out, give feedback, and help fix bugs. Prepack is a tool that optimizes JavaScript source code: Computations that can be done at compile-time instead of run-time get eliminated. Prepack replaces the global code of a JavaScript bundle with equivalent code that is a simple sequence of assignments. This gets rid of most intermediate computations...

Optimize JS is an experimental JavaScript transformation tool created to reduce initial parsing and execution time in older browser engines. It parses JavaScript into a syntax tree and identifies functions that are immediately invoked or likely to execute eagerly. Those functions are wrapped in parentheses so engines such as older V8 versions can avoid unnecessary lazy preparsing. The tool can operate from the command line or through a JavaScript API and can optionally generate source maps. Plugins were also created for Grunt, Gulp, and webpack workflows. ...

UglifyJS-old is the original version of UglifyJS, a JavaScript toolkit for parsing, compressing, mangling, and beautifying source code. Its parser converts JavaScript into an abstract syntax tree that can be inspected or manipulated programmatically. The code generator can rebuild readable JavaScript or remove unnecessary whitespace to reduce file size. Its mangler shortens variable names while accounting for scope, globals, eval calls, and with statements. Compression routines simplify expressions, combine declarations, transform conditionals, and remove unreachable code. ...
