Package description

What is @firebase/database?

The @firebase/database package is a client library for Firebase Realtime Database, a cloud-hosted database. Data is stored as JSON and synchronized in realtime to every connected client. It offers APIs that allow developers to easily store and sync data across multiple clients and platforms.

What are @firebase/database's main functionalities?

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();
