Simple FastAPI with Firebase Authentication

I always start my projects with a baseline that includes user management, which I handle using Firebase. This repository contains the most basic FastAPI application that I use as a starting point for new projects.

Now:

Set up a FastAPI app
Basic exception handeling
Connected to a Firebase Auth Project (user management)
"Protected" API Endpoint (which requires user auth)

In the Future:

basic SQLAlchemy, Redis setups / connectors
Simple CI to add tests easily and run them in GitHub actions

Setup:

First, make sure you have a Firebase project, with Auth app:

https://firebase.google.com/docs/auth

Then, clone the repo:

git clone https://github.com/adamcohenhillel/simple_fastapi_with_firebase.git

Install dependencies:

cd simple_fastapi_with_firebase
python3 -m pip install -r requirements.txt

Set environment variables [for Firebase]: for fulle explanation, read: https://firebase.google.com/docs/admin/setup#add-sdk

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"

And run:

python3 run_api.py

How to test the protected endpoint:

Create a user in your Firebase Auth App
Genertae a TokenID

POST https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=[WEBAPIKEY]
{
	"email": "email@gmail.com",
	"password":"password",
	"returnSecureToken":true
}

Send a request to your FastAPI protected endpoint

GET http://127.0.0.1:8000/api/simple_router/firebase_user
Authorization: TokenID
