The document provides an overview of Firebase, a cloud database and backend service founded in 2011, focusing on real-time data synchronization for mobile and web applications. It covers key features such as CRUD operations, authentication methods, security configurations, and the pros and cons of using Firebase. The conclusion emphasizes the need for developers to think independently and explore Firebase's capabilities.
Firebase not really_yohoho
- 1. Firebase Not really yohoho, but Yarr “one strange pirate notes”
- 2. Questions 1. Dive into Real Time Cloud Database 2. CRUD and Data Retrieving 3. Authentication and Security 4. Special Features you would like to use 5. Modules
- 3. Break Points 1. Main Goals 2. Firebase as Service Provider 3. Get it Working 4. Play Around 5. Something special 6. Pros and Cons 7. What are we waiting for? 8. Conclusion
- 4. Main Goals - provide with short review of technologie - play around and show examples - provide with directions of using Firebase - conclude everything
- 5. Firebase as Service Provider Main Information Firebase 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
- 6. Firebase as Service Provider Services: - Real Time Database Provider - Hosting - Simple Login
- 7. Firebase as Service Provider Real Time Database Provider Firebase 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
- 8. Firebase as Service Provider Languages: - Java Script - Android - iOS - Node.js - Java - Objective-C Frameworks: - Angular - Ember - Backbone - React
- 9. Get it Working: Data Data Storage: - JSON-structed - relative-oriented How it works: - pub/sub server - web-sockets
- 10. Get it Working: Start Installation: - <script src="https://cdn.firebase.com/js/client/2.2.4/firebase.js"> </script> - bower install firebase - npm install firebase
- 11. Get it Working: Create DB 1. Sign Up: https://www.firebase.com/ 2. Create Database
- 12. Get it Working: Connect Establish Database Connection:
- 15. Play Around: CRUD CRUD in Firebase: - flexible (as many ways as you can imagine) - one method and a lot of results
- 16. Play Around: Create Create: - push(); - set();
- 17. Play Around: Create push(); - soft insert: just adds a new object
- 18. Play Around: Create before push(); after push();
- 19. Play Around: Create unique ids
- 20. Play Around: Create set(); - strong: replace all the existing data
- 21. Play Around: Create before set(); after set();
- 22. Play Around: Create push(); - adds new object - assigns unique Id set(); - replace referenced data by incoming object - doesn’t assign unique Id
- 23. Play Around: Events Events: - on/once ‘value’ - on/once ‘child_added’ - on/once ‘child_removed’ - on/once ‘child_moved’
- 24. Play Around: Data View Data View: - data snapshot - val(); - exists() - child(); - parent(); - hasChild(); - hasChildren(); - isNumbers(); - isString(); - isBoolean(); - isNumber(); - getPriority();
- 25. Play Around: Read Read: - on.(‘value’); - on.(child_added’); - on.(child_removed’); - on.(‘child_changed’); - on.(‘child_moved’);
- 28. Play Around: Read on.(‘child_added’) <= show object key
- 29. Play Around: Update Update: - update(); - set();
- 30. Play Around: Update update(); new field
- 31. Play Around: Delete Delete: - remove();
- 33. Play Around: Search Search 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()
- 34. Play Around: Search Source Database:
- 35. Play Around: Search orderByChild(); startAt(); endAt();
- 36. Play Around: Search limitToFirst(); equalTo();
- 38. Play Around: Auth Pretty-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)
- 39. Play Around: Auth Auth Settings:
- 40. Play Around: Auth Create New User:
- 41. Play Around: Auth User List:
- 43. Play Around: Security Access Permissions: - .read - .write - .validate - .indexOn Variables: - auth - $location - now - root - data - new Data Methods: - val() - child() - parent() - isNumber() - isString() - matches(regex) Operators: - +,-,*,/,% - ===, !==, &&, ||, >, <
- 45. Play Around: Security Security Rules:
- 46. Play Around: Security Security Rules & Authentication: - not authenticated user
- 47. Play Around: Security Security Rules & Authentication: - authenticated user - read soldiers record
- 48. Play Around: Security Security Rules & Authentication: - authenticated user - write soldiers record
- 49. Play Around: Security - not flexible security rules - breaks search ability - complicated in configuration - force to duplicate data
- 50. Something Special onDisconnect(): - set(); - update(); - remove(); - cancel(); ServerValue: - TIMESTAMP databaseReference.child(‘.info’) - authenticated - connected - serverTimeOffset
- 51. Pros and Cons Pros: - 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
- 52. Pros and Cons Free Trial Plan: - 50 connections - 5 GB Data Transfer - 100 MB Data Storage - 1 GB Hosting Storage - 100 GB Hosting Transfer Paid Plans: https://www.firebase.com/pricing.html
- 54. What are we waiting for? - map reduce - url handling
- 55. Links: no porn :( https://www.firebase.com/ https://www.firebase.com/blog/ https://github.com/firebase/
- 56. Conclusion var databaseReference = new Firebase(‘https://thanks.for.listening/’); databaseReference.set({ conclusion: ‘think on your own’ });
- 57. Put Something Here var presentation = { author: { name: ‘Roman Sachenko’, email: ‘roman.sachenko@gmail.com’, skype: ‘roman.sachenko’, statusMessage: ‘there is no way, but the hard way’ }, subject: ‘Firebase: not really yohoho, but yarr’, date: new Date(‘2015/04/30’), };
