Point your Firebase C++ SDK at Lark by passing your Lark URL to Database::GetInstance(). Everything else (listeners, writes, queries) works without changes.

​
Setup

Add the Firebase C++ SDK to your project. Follow the Firebase C++ setup guide for your platform (Android NDK, iOS, or desktop). Make sure the Realtime Database library is linked:
  • Android: firebase_database in your CMakeLists.txt
  • iOS: firebase.framework and firebase_database.framework
  • Desktop: firebase_database library

​
Connect to Lark

Pass your Lark URL when getting the database instance: 
#include "firebase/app.h"
#include "firebase/database.h"

firebase::App* app = firebase::App::Create();

// Change this from https://PROJECT_ID.firebaseio.com
firebase::database::Database* database =
    firebase::database::Database::GetInstance(
        app, "https://your-lark-project-id.larkdb.net");

firebase::database::DatabaseReference ref =
    database->GetReference("players/alice");
If your google-services.json (Android) or GoogleService-Info.plist (iOS) already has the database URL, you can update it there instead and use Database::GetInstance(app) without a URL argument.

​
Database routing

If your Firebase app stores many independent data silos under path prefixes (game rooms, workspaces, etc.), see Database routing for options on splitting them into separate Lark databases.
