RxFirebase

RxJava wrapper for Firebase for Android. This library allow you to use Observable model of RxJava with Firebase instead of all the different kind of listeners.

Currently, the library supports following from the Firebase Suite:

• Firebase Realtime Database
• Firebase Authentication.

Usage

Setup the Firebase project and SDK as per the docs.

Use RxDatabase and RxAuthentication classes to get the RxJava equivalent for similar APIs in official library. Both the classes have public static methods for such tasks.

Show me the code

Write data

RxDatabase.setValue(databaseReference, value)
          .subscribe(isSuccessful -> Log.v(TAG, "Write operation: " + isSuccessful));

Read data

RxDatabase.getValueEventListener(databaseReference)
          .subscribe(dataSnapshot -> {
            // Do Something
          }, e -> Log.e(TAG, e.getMessage(), e));

RxDatabase.getChildEventListener(databaseReference)
          .subscribe(childEvent -> {
            // Do Something
            // Notice ChildEvent object instead of DataSnapshot type
          }, e -> Log.e(TAG, e.getMessage(), e))

Authenticate

RxAuthentication.getAuthListener(FirebaseAuth.getInstance())
          .subscribe(auth -> {
            FirebaseUser user = auth.getCurrentUser();
            if (user != null) {
              // User is signed in
              Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
            } else {
              // User is signed out
              Log.d(TAG, "onAuthStateChanged:signed_out");
            }
            // ...
          });
