parallel-es

parallel.es

A JavaScript library that simplifies parallel computation in the browser (and other environments soon).

Getting Started

Install the library using npm:

npm install --save parallel-es

Perform a single computation on a worker thread:

import parallel from "parallel-es";

parallel.run(function () {
	//… compute
	return [1, 2, 3];
}).then(result => console.log(result));

Or use the reactive api that automatically schedules the work onto multiple worker without any additional doing:

parallel.range(0, 100000)
	.map(value => value * value)
	.then(result => console.log(result));

Debugging Support

The Library uses Function serialization and therefore debugging is not supported out of the box. However, there is a webpack plugin that rewrites your code in a way that allows debugging (at least in Chrome and Firefox Nightly).

Referencing Functions and Variables

The library uses function serialization and therefore the outer scope is no longer available when the function is invoked in the worker thread. However, there is a webpack plugin that rewrites your code and allows you to use const variables from the outer scope or reference functions.

Documentation

The API Documentation is available online. The wiki describes the architecture and programing model in more detail.

Examples

An example project using parallel-es and comparing it performance to related projects is parallel-es-example. The examples are hosted here.
