2. The Realtime Backend for your App
3. Creating an app shouldn’t require managing complex infrastructure.
4. THE FULL STACK
5. The full stack is never really that simple
6. … and neither is the client side
7. The user doesn’t care about your backend
8. THE USER EXPECTS Speed Offline Multi-platform Simple Authentication
9. FIREBASE The Realtime Backend for your App
10. THE FIREBASE BACKEND
12. CLOUD DATABASE NoSQL data-store Returns JSON from a RESTful API
14. REALTIME DATA Whenever data is updated in Firebase, it sends the update down to every listening client
16. STORE DATA Firebase ref = new Firebase("https://<your-firebase-app>.firebaseio.com/message"); ref.setValue("All the things");
17. SYNC DATA Firebase ref = new Firebase("https://<your-firebase-app>.firebaseio.com/message"); ref.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot snapshot) { System.out.println(snapshot.getValue()); } @Override public void onCancelled(FirebaseError error) { } });
18. OFFLINE
19. INTERMITTENT OFFLINE What happens when you go through a tunnel? Firebase clients store a local cache of your data. When the user goes offline, the app still works as expected with the local cache.
20. ENTENDED OFFLINE What happens when you go on a flight? On mobile, Firebase persists data to a local store. The app will continue to work even across app restarts.
21. ONE LINE OF CODE Firebase.getDefaultConfig().setPersistenceEnabled(true);
23. Firebase supports several forms of authentication Email & Password Google Twitter Facebook Github Anonymous … and even custom backends
24. AUTHENTICATION ref.authWithOAuthToken("google", "<OAuth Token>", new Firebase. AuthResultHandler() { @Override public void onAuthenticated(AuthData authData) { // the Google user is now authenticated with your Firebase app } @Override public void onAuthenticationError(FirebaseError firebaseError) { // there was an error } });
26. SECURITY By default everyone can read and write { "rules": { ".read": true, ".write": true, } }
27. SECURITY Everyone can read, but no one can write { "rules": { ".read": true, ".write": false, } }
28. SECURITY Secure specific parts of your firebase { "rules": { ".read": true, “message”: { ".write": false, } } }
29. WELL DOCUMENTED
30. FIREBASE META-DATA 276,348 registered developers 1M concurrent users on Firebase sites Joined Google October, 2014
31. FOCUS ON YOUR APP The user doesn’t care about the backend What matters is that your app is fast and enjoyable
