  function MyFirebaseNode(this, config) {
    RED.nodes.createNode(this, config);

    // Get the config-node
    const configNode = RED.nodes.getNode(config.database);

    // Init the RTDB and subscribe to the communication status
    configNode.addStatusListener(this.id, "rtdb");

    // The RTDB reference instance
    const rtdb = configNode.rtdb.database;

    // Gets data from msg.path and yields a `payload`
    this.on("input", async (msg, send, done) => {
      try {
        const snapshot = await configNode.rtdb.get(msg.path);
        send({ payload: snapshot });
        done();
      } catch (error) {
        done(error);
      }
    });

    // Unsubscribe the communication status
    this.on("close", (done) => configNode.removeStatusListener(done));
  }

  RED.nodes.registerType("my-firebase-node", MyFirebaseNode);
};
