Web Workers

Introduction

This API is useful to generate threads for parallel executions.

Note that it includes a synchronous method to load scripts: importScripts()

Contacts

We are looking for representatives of this HTML5 API to discuss of potentially needed updates to consider server-side implementations

Debate

Any Server-Side JavaScript context could be implemented as a remote Worker implementing the WorkerGlobalScope interface:

SSJS Implementations

Node.js

Node.js provide a different API called cluster:

• http://nodejs.org/api/cluster.html

A third party module with the W3C API exists: node-worker

RingoJS

An adapted version is available:

• http://ringojs.org/api/master/ringo/worker/

Wakanda
