6. @douglasdrumond Firebase vs Realm Custo 6
7. @douglasdrumond Custo Realm: •Grátis •US$ 1500/mês •Enterprise Firebase: •Grátis •US$ 25/mês •Pay as you go 7
8. @douglasdrumond WINNER 8
9. @douglasdrumond Setup Realm // Authenticating the User User user = User.login(Credentials.google("google token"), "http://realm.example.com:9080/auth"); // Opening a remote Realm String realmURL = "realm://realm.example.com:9080/~/userRealm"; SyncConfiguration config = new SyncConfiguration.Builder(user, realmURL).build(); Realm realm = Realm.getInstance(config); // Any changes made to this Realm will be synced across all devices 9
10. @douglasdrumond Setup Firebase // Write a message to the database FirebaseDatabase database = FirebaseDatabase.getInstance(); DatabaseReference myRef = database.getReference("message"); myRef.setValue("Hello, World!"); 10
11. @douglasdrumond WINNER 11
12. @douglasdrumond Leitura em tempo real (Realm) list = realm.where(TaskList.class) .equalTo(TaskList.FIELD_ID, id).findAll(); list.addChangeListener( new RealmChangeListener<RealmResults<TaskList>>() { @Override public void onChange(RealmResults<TaskList> results) { updateList(results); } }); updateList(list); 12
13. @douglasdrumond Leitura em tempo real (Firebase) // Read from the database myRef.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot dataSnapshot) { String value = dataSnapshot.getValue(String.class); Log.d(TAG, "Value is: " + value); } @Override public void onCancelled(DatabaseError error) { } }); 13
14. @douglasdrumond Escrita (Realm) final Task task = realm.createObject(Task.class); task.setText(“Fazer apresentação“); 14
15. @douglasdrumond Escrita (Firebase) private void writeNewUser(String userId, String name) { User user = new User(name); mDatabase.child("users").child(userId).setValue(user); } 15
16. @douglasdrumond WINNER 16
17. @douglasdrumond Curva de aprendizado Realm tem uma sintaxe semelhante a ORMs A modelagem do Firebase é um pouco mais complexa 17
18. @douglasdrumond Principal diferença Realm é offline first com sync Firebase é sync first com offline Pense no que isso significa para sua arquitetura 18
19. Grazie mille! @douglasdrumond
