WeSC

We are the Superlative Components!

A streaming web component bundler written in Rust using the lol-html parser.

The idea is to create a single-file HTML component format and builder that builds the HTML result super fast (streaming, low memory) and is server language agnostic.

TODO: The JS (and CSS) in the top level script and style tag are bundled up separately and can be output as JS and CSS files.

Features

Streaming HTML bundler
Web component definition
Default and named slots with fallback content
Declarative Shadow DOM
CSS bundling
JS bundling
