NodeJs how to create a non-blocking computation

Question

I am trying to get my head around creating a non-blocking piece of heavy computation in nodejs. Take this example (stripped out of other stuff):

http.createS         


        

Answer 1

You can't do that directly, without using some of the IO modules in node (such as fs or net). If you need to do a long-running computation, I suggest you do that in a child process (e.g. child_process.fork) or with a queue.
