How can I manage a child_process from separate node.js processes?

Question

I want to spawn a child process from a node.js process and after performing certain async operations, I want to pause the process.

Then another Node.js process will be running which needs to resume the process based on some event it will be listening to.

I can't seem to find how can I accomplish this in node.js ?

You can use Redis Pub/Sub to achieve this.

Thanks Vineet. While you have pointed in the direction of establishing communication between two separate node.js processes, my problem is a little more difficult to tackle. I need them to control a common unix child_process and need help in that direction.

This should help you achieve event based control across processes, if you can be a bit more specific I can try to help you on it :)

This helped indeed! My approach towards the solution needed to change. Event based solution worked great. thanks!
