WebAssembly

Use from any JavaScript environment — browsers, Deno, and Cloudflare Workers.

npm

npm install @xberg-io/tree-sitter-language-pack-wasm

CDN (browser)

<script type="module">
  import { availableLanguages, parseString } from "https://cdn.jsdelivr.net/npm/@xberg-io/tree-sitter-language-pack-wasm/+esm";
  console.log(availableLanguages());
</script>

Deno

import { availableLanguages, parseString } from "npm:@xberg-io/tree-sitter-language-pack-wasm";
console.log(availableLanguages());

The WASM package is a static curated subset of parsers compiled into the module. It does not expose the native download/cache helpers.
