Overview

FastAPI-Users 10.0, released on March 1, 2022, introduces dependency injection for authentication and user management.

Main Features

Dependency injection

Authentication is handled through FastAPI's dependency injection system, making configuration more modular and testable.

python 
from fastapi import Depends, FastAPI
from fastapi_users import FastAPIUsers
from fastapi_users.authentication import BearerTransport, JWTStrategy

def get_jwt_strategy() -> JWTStrategy:
    return JWTStrategy(secret='SECRET', lifetime_seconds=3600)

bearer_transport = BearerTransport(tokenUrl='auth/jwt/login')

# fastapi_users = FastAPIUsers[User, uuid.UUID](
#     get_user_manager,
#     [auth_backend],
# )

Pre-configured routes

Registration, login, and profile management routes are pre-configured and customizable via dependencies.

python 
from fastapi import FastAPI

app = FastAPI()

# Automatic auth routes
# app.include_router(
#     fastapi_users.get_auth_router(auth_backend),
#     prefix='/auth/jwt',
# )
# app.include_router(
#     fastapi_users.get_register_router(UserRead, UserCreate),
#     prefix='/auth',
# )
