About wasm

A reference skill for WebAssembly development, covering compilation, WASI, the Component Model, and runtimes. It is for developers evaluating or building browser, edge, server, and embedded applications that use WASM.

Key features

  1. 01Rust, Go, C/C++ and AssemblyScript compilation
  2. 02WASI command and runtime examples
  3. 03Typed Component Model composition
  4. 04Browser, edge, server and embedded use cases

Use cases

  1. 01Compile Rust code for browser use
  2. 02Run WASI applications with Wasmtime
  3. 03Compose typed modules across languages
  4. 04Evaluate WASM for edge or embedded workloads

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/thebeardedbearsas/claude-craft --skill wasm

After installing, type/wasmin Claude Code to confirm it loaded.

Details

From the project README

WebAssembly (WASM) — Component Model, WASI

WASM pour performance critique, polyglot runtime, edge computing.

Use Cases

Browser — Crypto, image (Figma, Google Earth)
Edge — Cloudflare Workers, Fastly
Server — Plugins sandboxés (Envoy)
Embedded — IoT, automotive

Compilation

Rust — wasm-pack (~50KB, perf)
Go — GOOS=js GOARCH=wasm (~2MB)
C/C++ — Emscripten (legacy)
AssemblyScript — TypeScript-like

Rust to WASM

use wasm_bindgen::prelude::*;
#[wasm_bindgen] pub fn add(a: i32, b: i32) -> i32 { a + b }

wasm-pack build --target web

import init, { add } from './pkg/wasm.js';
await init(); add(2, 3);

WASI (System Interface)

rustc --target wasm32-wasi main.rs -o app.wasm
wasmtime app.wasm

Component Model

interface math { add: func(a: s32, b: s32) -> s32 }

Compose Rust/Go/C++ modules typés.

Edge (Cloudflare)

import wasm from './processor.wasm';
export default {
  async fetch(req) {
    const inst = await WebAssembly.instantiate(wasm);
    return new Response(inst.exports.process(req.body));
  }
};

Runtimes

Wasmtime — Fast, WASI
Wasmer — Universal
WasmEdge — Edge, K8s
