running multiple files on node js at the same time

Question

running multiple files on node js at the same time

i have a simple node script

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
}).listen(1337);

now when i run this, i can go to localhost:1337 and see the output but , in the command module, its frozen for some reason. until i press ctrl+C its frozen and only after Ctrl+C im allowed to execute more files.

is this just me or its the way it was designed. If it is can someone point me in the right direction as to how to have it always listen on port 1337 or another for different files.

javascript
node.js

This is normal behavior. Node will only exit if there's nothing more to do (or if you manually stop it via Ctrl+C). Since you told http to listen(), the process will stay alive indefinitely.

It's not exactly clear what you're asking, but if you want to run additional files inside your app, you simply require() them.

var otherFile = require('./otherFile.js') // the .js is optional

otherFile will now be set to whatever you do to module.exports in otherFile.js.

You should read the module documentation to get a full understanding of how require works.

If you want to run other unrelated files with node at the same time, open a separate command prompt window.

I will now read between the lines a little: it looks like you might be wondering how to get http to serve files from disk like other web servers. Node doesn't work like traditional web servers. Your code has to explicitly handle serving up things from disk.

Fortunately, there are frameworks/libraries that make it easy to do. If you're building any kind of web service, you should really use a framework rather than the raw http module. I recommend looking at Express. It's easy to serve files from disk with express.static.
