Setting up a webserver with Node and Express is easy very easy.
Here is a small example:
var express = require("express"); var app = express(); app.get("/", function (request, response) { response.send("Hello world!"); }); app.listen(3000); Running this and navigating to http://localhost:3000 will give you the following result:
If you only have a few of those endpoints (app.get etc.) things will be fine living in the same index.js file. But what if this starts growing?
