Firebase implementation based on REST API, based on micropython-firebase-realtime-database from ckoever.

You can use uPip to install library from PyPi

import upip upip.install("micropython-firebase-auth")

or you can just upload firebase_auth/firebase_auth.py to your microcontroller:

python pyboard.py -d PORT -f cp firebase_auth.py :

- sign_in - sign_out - sign_up 

ujson, urequests, time, sys 

import time import network wlan = network.WLAN(network.STA_IF) wlan.active(True) if not wlan.isconnected(): wlan.connect("ssid", "pass") print("Waiting for Wi-Fi connection", end="...") while not wlan.isconnected(): print(".", end="") time.sleep(1) print()

from firebase_auth import FirebaseAuth auth = FirebaseAuth("API_KEY")

The API key is required, read about it here or you can find it at Project Settings > General in your project's console

auth.sign_in(email, password)

Authenticate a user with email and password

auth.sign_up(email=None, password=None)

Registers an account with the given email and password

• leave email and password empty to sign in anonymously

  auth.sign_up(None, None) # Sign in as guest

  Example:

auth.sign_up("email", "password") print("Hello, " + auth.user.display_name)

auth.sign_out()

Clears authentication session and stored user data

auth.user: dict()

Returns the user data for the currently authenticated user

• Properties

  uid
email
display_name - Optional
  photo_url - Optional

auth.session: AuthSession

The AuthSession object used to handle requests to the backend

session.request(method, endpoint, data=None, method=None, **kwargs)

Make a request to an auth endpoint requiring an idToken (the accessToken) (if method is not None, else an endpoint that returns tokens)

session.access_token

Gets the access token for use within other Firebase services such as RTDB, Firestore, etc.

AuthSession.load_credentials()

Reads a stored version of session credentials from a credentials.json file

AuthSession.save_credentials(creds)

Stores a session credentials object into credentials.json file Example:

# Storing data on system before going to sleep for 10s import machine creds = auth.session.credentials AuthSession.save_credentials(creds) machine.deepsleep(10000)
