How to effectively handle errors from a Firebase JavaScript database connection

I am struggling with this code and need help identifying how to capture errors.

  const dataRef = database.ref('test');
  dataRef.on('value', snapshot => {
    snapshot.val();
  });

Does anyone have any suggestions on how I can approach this issue?

Answer №1

In the event that your client lacks permission to access information from the given reference, Firebase will trigger the optional second callback function provided in the on() method. For example:

const collectionRef = database.ref('test');
collectionRef.on('value', snapshot => {
  snapshot.val();
}, error => {
    console.error(error);
});

I suggest exploring the Firebase reference documentation for additional insights and tips like this one.
