sspawn

Simple and fault-tolerant server spawner for Node.js

What ?

sspawn uses node's cluster library to create forked processes of your application. When an error occurs, well, it's catched in a domain. Basically, your worker will crash but it will be recreated in seconds while the others continues processing requests.

So when uncatched and critical errors occurs, your node server continues working.

There's also a slight performance boost. Two synchronous tasks can run in parallel now. It's like a super-lightweight unicorn-like server for node.

Installation

npm install sspawn

Usage

// Given a server (node http module, express, restify, ...)
var server = ...;

// Require sspawn to create a Spawner instance, pass it the server, the port and the options
var spawner = require(server, 8000);

// Spawn !
spawner.start();

Documentation
