Node.js - lightweight and efficient
Using Node.js you can write a web server in as little as six lines of code. Here is a variation for the sample from the Node.js (Node.js Synopsis) //Imports the http library var = require(http); http.createServer(function(request, response){ response.writeHead(200,{'Content-Type':'text/plain'}); response.end('Hello World\n'); }).listen(8124); console.log('Server running at http://127.0.0.1:8124/'); I was asking myself why would i want a server side javascript (which is the whole idea of Node.js) ? Besides that it uses a non-blocking I/O model (this means that other processing can continue if it does not depend fro an I/O to complete, kind of like an asynchronous call to perform the I/O) . One use case that i can think of is that I can wrap other services (e.g. other source of data like json/xml) specially ones that are exposed as web service APIs (e.g. Google APIs).
