Simple Node.js Server

simple-server.js

// define runtime constants
var PORT    = 8000;

// import modules needed to make the server (http and filesystem modules for now)
var http    = require('http');
var fs      = require('fs');

var server  = http.createServer(requestHandler);

function requestHandler(request, response) {
    // write the headers of our response
    response.writeHead({
        'Content-Type' : 'text/plain'
    });
    
    // send our response to client and end the connection
    response.end("Hello World!");
}

// start the server and bind it to port 8000
server.listen(PORT);

// to run this application, go to your command line, cd into this folder, and type `node server`
// that's it, to access it through your browser, go to http://localhost:8000

Hey... I had to type 'node simple-server' instead 'node server'... and why doesn't this work in safari? Got it working in chrome though... Thanks!
