/kernel-quickjs

QuickJS-in-WASM kernel — sandboxed JavaScript, edge-safe, no node:vm required.

Part of wasmagent — a TypeScript + WASM agent runtime.

Install

npm install /kernel-quickjs /core quickjs-emscripten @jitl/quickjs-wasmfile-release-sync

Usage

import { QuickJSKernel } from "/kernel-quickjs";

const kernel = new QuickJSKernel();
const result = await kernel.run(`[1,2,3].reduce((a,b) => a+b, 0)`);
console.log(result.output); // 6

Drop-in replacement for VmKernel on Cloudflare Workers (which forbids node:vm), Vercel Edge, Deno Deploy, and any environment where you want true language-level sandboxing without spinning up a microVM.
