# Workerize [![npm](https://img.shields.io/npm/v/workerize.svg?style=flat)](https://www.npmjs.org/package/workerize) [![travis](https://travis-ci.org/developit/workerize.svg?branch=master)](https://travis-ci.org/developit/workerize)

> Moves a module into a Web Worker, automatically reflecting exported functions as asynchronous proxies.

- Bundles a tiny, purpose-built RPC implementation into your app

- If exported module methods are already async, signature is unchanged

- Supports synchronous and asynchronous worker functions

- Works beautifully with async/await

- Just **800 bytes** of gzipped ES3

## Install

```sh

npm install --save workerize

```

### Usage

Pass either a function or a string containing code.

**worker.js**:

```js

let worker = workerize(`

	export function add(a, b) {

		// block for half a second to demonstrate asynchronicity

		let start = Date.now();

		while (Date.now()-start < 500);

		return a + b;

	}

`);

(async () => {

	console.log('3 + 9 = ', await worker.add(3, 9));

	console.log('1 + 2 = ', await worker.add(1, 2));

})();

```
