Wraps https://npmjs.org/package/wasi, created by @devsnek, in an ESM integration API.

Note this API is only an experiment in integrating WASI with the ES Module system in Node.js and is not based on any existing proposal.

npm install wasi_unstable

main.mjs

import * as M from './wasi-file.wasm';
import { run } from 'wasi_unstable';

run(M, {
  // defaults:
  env: process.env,
  args: process.argv.slice(1)
});

Executed with:

node --experimental-modules --experimental-wasm-modules main.mjs
