Perks of Firebase

• Fast Data Synchronization
• No backend server to worry about
• Built-in Authentication
• Free-hosting*
• Instant Scalability 

Save Data to the cloud

Since Firebase itself is a No SQL database you easily store data as simple JSON documents

{
  "users": {
    "mchen": {
      "friends": { "brinchen": true },
      "name": "Mary Chen",
      // our child node appears in the existing JSON tree
      "widgets": { "one": true, "three": true }
    },
    "brinchen": { ... },
    "hmadi": { ... }
  }
}

Realtime Data

• Firebase is simply a database with RESTful API
• However, not just an API
• Updates every client with the newest information
• Huge Selling Point

Basics of Data

Creating a Firebase Reference

• Before reading and writing data we need to creat a reference to it. This data is loaded with a specified URL

var ref = new Firebase('https://youKaraoke.firebaseio.com/');

• You can also reference different paths

var roomRef = new Firebase("https://youKaraoke.firebaseio.com/room");

Saving Data

Standard ways to save 

• .set()
• .push()
• .update()

Best Practices

• Avoid Nesting

{
"rooms": {
    "one": {
        "name": "room alpha",
        "type": "private",
        "messages": {
    "m1": { "sender": "mchen", "message": "foo" },
    "m2": { ... },
            }
        }
    }
}

Retrieving Data

Listeners

• Data is retrieved by attaching an asynchronous listener to a Firebase reference.
• The listener will be triggered once for the initial state of the data and again anytime the data changes

ref.on("value", function(dataSnapshot) {
    console.log(dataSnapshot.val());
});

Read event Types

• value
• child added
• child changed
• child removed

Awesome FrameWorks

• AngularFire
• EmberFire
• ReactFire
• BackboneFire

$firebase service

• The primary purpose of $firebase is to manage synchronized data
• These are some of the methods it contains 

1. $asObject()
2. $asArray()

• Three-way Data Binding

Hosting

Quick and Easy

• Just three steps 

$ npm install -g firebase-tools

$ firebase init

$ firebase deploy

• Gets deployed to 

your-firebase-name.firebaseapp.com

Go try firebase
