an ONLINE COMPILE app using NODE.JS?

assume I want to do a online compile web app based on Node.js that:

• User can upload his code (CPP for example)
• The server compile it , and response the result (succeed or not)
• User give some input for the program (STDIN)
• The server run the program and response the result (STDOUT)

so it means

• interacting with system, or say shell;
• run programs on server, get the result;

which module(s) support these function?

Is there any example for this thing?

Such tool does exist.... CodePad

Hope it will help as it did help me while practicing for c like interviews :>
