QtFirebase

An effort to bring the Firebase C++ API to Qt 5

QtFirebase aims to bring all the features of the Firebase C++ SDK to Qt 5 - both as C++ wrappers and as QML components.

Please bear in mind that the Firebase C++ SDK currently only supports the mobile platforms Android and iOS.

You can still build QtFirebase on other platforms as the project provides stub implementations or placeholder components - they just return default/empty values when used. Because of this you won't see e.g. ads from AdMob in your desktop builds.

This is due to Google's own limitations in the Firebase C++ SDK implementation.

The Firebase C++ SDK claim to already provide stub implementations for easier building on unsupported platforms - QtFirebase have chosen not to link to unnecessary closed source code - thus we do not link against the stub implementations from Google.

Stability

The Firebase C++ SDK has (or has had) a lot of stability issues - which QtFirebase does its best to work around by wrapping the API into more Qt/C++ friendly classes that prevent some of the bugs and crashes found so far. Please use the latest SDK version to get the latest fixes.

When you encounter bugs; Please see if they are known issues here or here - before reporting
