Ezno

This contains a JavaScript edition of Ezno

CLI

This package includes a JS & WASM based version of the CLI. You can use as follows

node dist/cli.cjs info
# or
deno run -A dist/cli.mjs info

Library example

For a environment that supports node:fs, you can use a version that initializes the WASM for you

import { build } from "ezno/initialised";

// Just use a local string. Could use readFileSync for FS access
const fs_handler = (_path) => "const x = !t ? 4 : 5;";
console.dir(build("input.js", fs_handler), { depth: 5 })

For the web, init() is needed to load the WASM before calling any functions.

import { init, build } from "ezno";

await init();

const res = build("input.js", () => "const x = 2 + 5;");

document.querySelector('#app').innerHTML = `<pre>${JSON.stringify(res)}</pre>`;

Commands for building this package

Run this from this folder, not the root:

npm run clean
npm run build

See package.json for the other building commands.

• It first builds the WASM binary with rustc, cargo build --lib --target wasm32-unknown-unknown
• It then binds (builds associate JS library) into the build folder with wasm-bindgen --out-dir build --target web
• It then bundles (and generates CJS & EJS formats) with some associate JS using unbuild into the dist folder
