NodeJS simple web app/server environment (using express, express's compress and prerender-node packages) set to serve out static content in root directory. For when you need a simple web server without the bloat.

app.js

//set up the app
var express = require('express');
var app = express();

//enables express-toobusy, which keeps it from melting under HIGH pressure
//app.use(require('express-toobusy')());

//enables compress and prerender-node
//app.use(express.compress());
//app.use(require('prerender-node'));

//setting cache-control
//var aYear = 31536000000;  //365*aDay
//var aMonth = 2592000000;  //30*aDay
var aDay = 86400000;        //1000ms*60s*60min*24hr

//establishes path of static files in root directory
app.use(express.static(__dirname + "/public", { maxAge: aDay }));

//establish simple text catch for Error 500 and Error 404
app.use(function(err, req, res, next){
  console.error(err.stack);
  res.send(500, "Something broke!");
});

app.use(function(err, req, res, next){
  res.send(404, "Sorry, can't find that!");
});

//set to listen on environment port or port 3000, if no detected environment port
var portToListenOn = process.env.PORT || 3000;
app.listen(portToListenOn);
console.log("NodeJS serving content from "+__dirname+"/public/ on localhost:"+portToListenOn);
