A far from complete collection of Hello World examples for various Node.js web frameworks.

After using the Express command line generation untility, you get a very basic layout.jade. Here's the standard modifications I make for use with BootstrapCDN.

Here are some simple and basic rules I've found for building applications that are maintainable and perform well, both in speed and stability. These rules, at one level or another, can apply to smaller modules and libraries, scripts, as well as fully featured large scale applications (both web and otherwise). In this post I will focus more on web applications, since that's where I've spent most of my time. At a higher level, they should apply to almost all areas of software development.

Sinatra

require 'sinatra'
get '/' do
  "Hello World"
end

Express

var app = require('express');
app.get('/', function(req, res) {
    res.send("Hello World!");
});
app.listen(8000);
