A Gentle Introduction to Prepack, Part 1

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

var cookieParser = require('cookie-parser');
var session = require('express-session');
var flash = require('express-flash');
var handlebars = require('express-handlebars')

Get only new items from Firebase
// assumes you add a timestamp field to each record (see Firebase.ServerValue.TIMESTAMP)
// pros: fast and done server-side (less bandwidth, faster response), simple
// cons: a few bytes on each record for the timestamp
var ref = new Firebase(...);
ref.orderByChild('timestamp').startAt(Date.now()).on('child_added', function(snapshot) {
console.log('new record', snap.key());
});
