🍱 Libraries

This is a collection of carefully crafted TypeScript libraries. These try to be minimal, unbloated and convenient.

Most of them are written with deno in mind, but most packages in this repository honors web standards which means they can be used with other runtimes such as Node.js, bun and even browsers.

🧑‍💻 Cli utilities

A set of useful CLI scripts are also provided. Please note that these can only be run on deno runtime.

TypeScript code coverage enhancer

Enhance coverage reports generated with deno coverage by adding syntax highlighting and better styling thanks to matcha.css.

deno run jsr:@libs/bundle/ts/cli/coverage --help

CSS formatter

Format CSS code similarly to prettier or deno fmt. Can be used with --check to validate that CSS code is correctly formatted.

deno run jsr:@libs/bundle/css/cli/fmt --help

CSS features compatibility checker

Print compatibility report for CSS features against MDN data for selected browsers.

deno run jsr:@libs/bundle/css/cli/check --help

XHTML formatter

Format HTML and HTML/XML code similarly deno fmt. Can be used with --check to validate that HTML/XML code is correctly formatted.

Warning

This formatter is currently experimental and may break your documents. It requires --unstable flag to be run without --check flag.

deno run jsr:@libs/bundle/xhtml/cli/fmt --help

Web assembly builder

Compile a rust project to Web assembly and minify output.

deno run jsr:@libs/bundle/wasm/cli/build --help
