Firebase Realtime Database is a cloud-hosted NoSQL database that allows you to store and sync data between your users in real-time. You can use the Firebase Realtime Database with Python using the firebase-admin library. Here is an example of how to send a message to the Firebase Realtime Database using Python:

  • Install the firebase-admin library: 
pip install firebase-admin
Enter fullscreen mode Exit fullscreen mode
  • Import the necessary modules: 
from firebase_admin import credentials, db
Enter fullscreen mode Exit fullscreen mode
  • Initialize the Firebase Admin SDK with a service account: 
cred = credentials.Certificate('path/to/serviceAccountKey.json') firebase_admin.initialize_app(cred, {'databaseURL': 'https://your-project-name.firebaseio.com'})
Enter fullscreen mode Exit fullscreen mode
  • Get a reference to the database: 
ref = db.reference()
Enter fullscreen mode Exit fullscreen mode
  • Send a message to the database: 
ref.child("messages").push({"text": "Hello, World!"})
Enter fullscreen mode Exit fullscreen mode
  • You can also listen for real-time updates to the database: 
def on_message(event): print(event.event_type) # can be 'put' or 'patch'  print(event.path) print(event.data) # new data at /path  my_stream = ref.child("messages").stream(on_message)
Enter fullscreen mode Exit fullscreen mode

Make sure to replace "path/to/serviceAccountKey.json" with the path to your service account key and "your-project-name" with the name of your Firebase project. The file will have the following structure:

{ "type": "service_account", "project_id": "your-project-id", "private_key_id": "your-private-key-id", "private_key": "-----BEGIN PRIVATE KEY-----\nyour-private-key\n-----END PRIVATE KEY-----\n", "client_email": "your-service-account-email", "client_id": "your-client-id", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://oauth2.googleapis.com/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/your-service-account-email" }
Enter fullscreen mode Exit fullscreen mode

Also, you can use the python library pyrebase to interact with the Firebase Realtime Database using the REST API, it has some more functionality than firebase-admin library.
