powered-by

An essential nodejs middleware inspired by Bryan O'Sullivan's (in)famous tweet:

Lance Armstrong takes drugs and wins the hardest bike race in the world 7 times. Programmers take drugs and what do we get? Node.js.

"But...what?"

Nothing. This middleware will just add a "X-Powered-By" header to all your outgoing HTTP responses saying:

"node.js: Programmers on drugs"

This HTTP header is (usually) not seen by your visitors and serves no (known) purpose other than "advertising" your stack. PHP adds it, seems like ASP did too. Contrary to these two, the running .jsnode version isn't displayed. The idea is just to have some fun and spread the node.js love, not make our apps a target to script-kiddies once a vuln is out.

"How do I even..?"

Just add it to your express app as you would for any other middleware:

var express = require('express');
var app = express();

app.use(require('node-powered-by'));

"I'm too hip for express!"

Oh well. I used to be like you once.

var http = require('http');
http.createServer(function (req, res) {
    return require('node-powered-by')(req, res, function () {
        res.end('Hello!');
        return;
    });
}).listen(process.env.PORT);

"Still...drugs are bad!"

The purpose isn't to advertise drug usage, just using a funny node.js quote.
