This is the pure-JavaScript implementation of MessagePack:

https://msgpack.org/

This is under development until v1.0.0. Any API will change without notice.

import { deepStrictEqual } from "assert";
import { encode, decode } from "@msgpack/msgpack";

const object = {
  nullOrUndefined: null,
  integer: 1,
  float: Math.PI,
  string: "Hello, world!",
  binary: Uint8Array.from([1, 2, 3]),
  array: [10, 20, 30],
  map: { foo: "bar" },
  timestampExt: new Date(),
};

const encoded = encode(object);
// encoded is an Uint8Array instance

deepStrictEqual(decode(encoded), object);

npm install @msgpack/msgpack

The NPM package distributed in npmjs.com includes both ES2015+ and ES5 files:

• /dist is compiled into ES2015+
• /dist.es5 is compiled into ES5 and bundled to singile file

If you use NodeJS and/or webpack, their module resolvers use the suitable one automatically.
