Realtime Data Syncing

This feature allows you to listen for and receive data in realtime from the Firebase database. Whenever data changes, the event is triggered and the callback function is executed with the updated data.

firebase.database().ref('/path/to/data').on('value', (snapshot) => {
  const data = snapshot.val();
  console.log(data);
});

Data Writing

Enables you to write data to a specified path in your Firebase database. This can be used to add new data or overwrite existing data at the path.

firebase.database().ref('/path/to/data').set({
  username: 'name',
  email: 'email@example.com',
  profile_picture : 'imageUrl'
});

Data Reading

Allows you to read data from your Firebase database. This method fetches data once without listening for changes.

firebase.database().ref('/path/to/data').once('value').then((snapshot) => {
  const data = snapshot.val();
  console.log(data);
});

Data Deleting

This feature enables you to delete data from your Firebase database at a specified path.

firebase.database().ref('/path/to/data').remove();
