When should I use firebase-messaging ?

• I want to receive push notifications sent using Firebase Cloud Messaging in a python application.

When should I not use firebase-messaging ?

• I want to send push notifications (use the firebase SDK instead)

• My application is running on a FCM supported platform (Android, iOS, Web).

Install

PyPi:

$ pip install firebase-messaging

Requirements

• Firebase configuration to receive notifications

Usage

Must be run inside an asyncio event loop.

python:

from firebase_messaging import FcmPushClient, FcmRegisterConfig

def on_notification(obj, notification, data_message):
    # Do something with the notification
    pass

credentials = None  # Start off with none or load from previous save
def on_credentials_updated(creds):
    # save the credentials to a file here for future use

fcm_config = FcmRegisterConfig(fcm-project-id, fcm-app-id, fcm-api-key, fcm-message-sender-id)
pc = FcmPushClient(on_notification, fcm_config, credentials, on_credentials_updated)
fcm_token = await pc.checkin_or_register()

await pc.start()

# Adapt the following for your usage
while some_condition_to_keep_listening:
    asyncio.sleep(2)
