Learning Node.JS Programming

April 2014 - Better late than never, but I should have begun this process a few months ago.

Hello World at Command Prompt

Open up a text file and enter:

// Call the console.log function.
console.log("Hello World");

Save file as hello-console.js and then at the command prompt, execute:
node hello-console.js

Obviously, that produces:
Hello World

Hello World HTTP Server

Add the following code to a file called:
hello-server.js


// Load the http module to create an http server.
var http = require('http');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.end("Hello World\n");
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

// Put a friendly message on the terminal
console.log("Server running at http://127.0.0.1:8000/");

Execute the code with
