@stencil-hq/wslab

The slab web driver: the SlabElement custom-element base class, the DOM Painter, and the Rust-kernel WASM binding glue plus sidecar. Components generated by slab gen wc import this package and subclass SlabElement; layout, animation, and interaction all run in the shared Rust kernel compiled to WASM.

Most users never install this directly — the compiler CLI @stencil-hq/slab emits components that depend on it:

bunx @stencil-hq/slab gen wc doc.slab -o dist --tag my-doc

<script type="module" src="./dist/doc.js"></script>
<my-doc style="display:block;width:800px;height:600px"></my-doc>

Set attributes/properties for document params; listen for CustomEvents for signals. Keep the emitted runtime and slab_kernel_bg.wasm sidecar next to the generated module when deploying.

Direct use

import { SlabElement } from '@stencil-hq/wslab';

Exports: SlabElement, Painter, param/color coercion helpers, and the types generated components rely on (SceneNode, SignalDef, SlabSignalDetail, …). Ships both compiled JS (dist/) and TypeScript source; Bun resolves the source directly via the bun export condition.
