dbRef.on('value', (snapshot) => {
  const data = snapshot.val();
  console.log(data);
});

Writing Data

const dbRef = firebase.database().ref('path/to/data');
dbRef.set({
  key: 'value'
}).then(() => {
  console.log('Data written successfully');
}).catch((error) => {
  console.error('Error writing data:', error);
});

Updating Data

This feature allows you to update specific fields at a specific path in the Firebase Realtime Database. The code sample demonstrates how to update data and handle success and error cases.

}).then(() => {
  console.log('Data updated successfully');
}).catch((error) => {
  console.error('Error updating data:', error);
});
