Firebase as Service ProviderMain InformationFirebase is a cloud services provider and backend as a service company based in San Francisco, California. The company makes a number of products for software developers building mobile or web applications. Firebase was founded in 2011 by Andrew Lee and James Tamplin and launched with a real time cloud database in April 2012. © Wikipedia

Firebase as Service ProviderServices:- Real Time Database Provider- Hosting- Simple Login

Firebase as Service ProviderReal Time Database ProviderFirebase provides a realtime database and backend as a service. The service provides application developers an API that allows application data to be synchronized across clients and stored on Firebase's cloud. © Wikipedia

Firebase as Service ProviderLanguages:- Java Script- Android- iOS- Node.js- Java- Objective-C

Frameworks:- Angular- Ember- Backbone- React

Get it Working: DataData Storage:- JSON-structed- relative-oriented

How it works:- pub/sub server- web-sockets

Get it Working: StartInstallation:- <script

src="https://cdn.firebase.com/js/client/2.2.4/firebase.js"></script>

- bower install firebase- npm install firebase

Get it Working: Create DB1. Sign Up: https://www.firebase.com/2. Create Database

let’s code, Yarr!

Play Around: CRUD

Create

Read

Update

Delete

Play Around: CRUDCRUD in Firebase:- flexible (as many ways as you can imagine)- one method and a lot of results

Play Around: CreateCreate:- push();- set();

Play Around: Createpush();

- soft insert: just adds a new object

Play Around: Createbefore push(); after push();

Play Around: Create

unique ids

Play Around: Createset();

- strong: replace all the existing data

Play Around: Createbefore set(); after set();

Play Around: Createpush();

- adds new object- assigns unique Id

set();- replace referenced data by incoming

object- doesn’t assign unique Id

Play Around: EventsEvents:

- on/once ‘value’- on/once ‘child_added’- on/once ‘child_removed’- on/once ‘child_moved’

Play Around: Data ViewData View:

- data snapshot- val();- exists()- child();- parent();- hasChild();- hasChildren();- isNumbers();- isString();- isBoolean();- isNumber();- getPriority();

Play Around: ReadRead:- on.(‘value’);- on.(child_added’);- on.(child_removed’);- on.(‘child_changed’);- on.(‘child_moved’);

Play Around: Readon.(‘value’)

Play Around: Readon.(‘value’)

Play Around: Readon.(‘child_added’)

<= show object key

Play Around: UpdateUpdate:- update();- set();

Play Around: Updateupdate();

new field

Play Around: DeleteDelete:- remove();

Play Around: Deleteremove();

Play Around: SearchSearch Process:

- no strong search queries- no real search engine

Search Methods:- on/once(‘value’)- orderByChild(), orderByKey(), orderByValue(), orderByPriority()- startAt(), endAt(), equalTo()- limit(), limitToLast(), limitToFirst()- ref()

Play Around: SearchSource Database:

Play Around: SearchorderByChild(); startAt(); endAt();

Play Around: SearchlimitToFirst(); equalTo();

Play Around: SearchequalTo();

Play Around: AuthPretty-looking and Easy:

- automatic user creation- service-side authentication- multiple authentication methods

Authentication Methods:- email and password (using pre-registered email and password)- social network-based (Facebook, Google, Twitter, GitHub)- anonymous (new session = new identifier) - custom (using pre-generated token)

Play Around: AuthAuth Settings:

Play Around: AuthCreate New User:

Play Around: AuthUser List:

Play Around: AuthAuthentication:

Play Around: SecurityAccess Permissions:

- .read - .write- .validate- .indexOn

Variables:- auth- $location- now- root- data- new Data

Methods:- val()- child()- parent()- isNumber()- isString()- matches(regex)

Operators:- +,-,*,/,%- ===, !==, &&, ||, >, <

Play Around: Security

Play Around: SecuritySecurity Rules:

Play Around: SecuritySecurity Rules & Authentication:

- not authenticated user

Play Around: SecuritySecurity Rules & Authentication:

- authenticated user- read soldiers record

Play Around: SecuritySecurity Rules & Authentication:

- authenticated user- write soldiers record

Play Around: Security- not flexible security rules- breaks search ability- complicated in configuration - force to duplicate data

Something SpecialonDisconnect():

- set();- update();- remove();- cancel();

ServerValue:- TIMESTAMP

databaseReference.child(‘.info’)- authenticated- connected- serverTimeOffset

Pros and ConsPros:

- fast- auto-scalable - service-side process handling - events-oriented- build-in graphic editor- easy to jump in- user-friendly- understandable API

Cons:- poor search engine- no map reduce implemented- no reference or join functionality- not counted amount of

connections

Pros and ConsFree Trial Plan:

- 50 connections- 5 GB Data Transfer- 100 MB Data Storage- 1 GB Hosting Storage- 100 GB Hosting Transfer

What are we waiting for?- map reduce- url handling
