Is it possible to develop a javascript function in Node.js?

Question

I am trying to execute a long run function from my main javascript file. I have 2 cpus, so how can I just unlock the function?

Answer 1

The following is the node.js documentation for branching processes and child processes in node.

http://nodejs.org/api/child_process.html

It looks like you could do something like this.

var child = require('child_process').fork('child.js'); child.on("message", function(){}); 

And in this case, you will need a child.js file.

Answer 2

For browser-side javascript, you use Web Workers for such a task, the functionality has been ported to NodeJS here. Web Worker Design for NodeJS , which wraps a child_process API call with a message passing to the web workers' capabilities.
