Integrate FastAPI into the Project

Task: Integrate FastAPI into the Project

Add FastAPI as a component within project to enhance API performance and support asynchronous operations.

Instructions:

Install Dependencies
Install FastAPI and Uvicorn:
```
pip install fastapi uvicorn
```
Create FastAPI App
- Inside your Django project, create a new directory called fastapi_app.
- Inside fastapi_app/, create __init__.py and main.py.
main.py example:
```
from fastapi import FastAPI

app = FastAPI()

@app.get("/hello")
async def hello():
   return {"message": "Hello from FastAPI"}
```
Run FastAPI Locally (for testing)
In the terminal, navigate to the Django project directory and run:
```
uvicorn fastapi_app.main:app --reload --port 8001
```

Configure ASGI Application
Modify your Django project’s asgi.py to include FastAPI routing:

import os
from django.core.asgi import get_asgi_application
from fastapi_app.main import app as fastapi_app
from django.urls import path
from django.conf.urls import re_path

django_asgi_app = get_asgi_application()

from fastapi.middleware.asgi import ASGIApp

application = ASGIApp(
   app=django_asgi_app,
   lifespan=None,
   sub_apps=[("/api/fastapi", fastapi_app)],
)

Update urls.py
Modify Django’s urls.py to include FastAPI routes:

from django.urls import path, include

urlpatterns = [
   path('admin/', admin.site.urls),
   path('api/fastapi/', include('fastapi_app.main')),
]

Add FastAPI Tests
Use httpx for testing FastAPI routes. Add the following to your tests:

import httpx
import pytest

@pytest.mark.asyncio
async def test_hello():
   async with httpx.AsyncClient() as client:
       response = await client.get("http://localhost:8001/hello")
       assert response.status_code == 200
       assert response.json() == {"message": "Hello from FastAPI"}

Update Dependencies
Make sure your Django project requirements reflect the new additions:
```
pip freeze > requirements.txt
```
Configure Deployment
Update your docker-compose.yml or deployment files to include Uvicorn alongside Django.

Deliverables:

Working FastAPI endpoint at /api/fastapi/hello.
ASGI integration with Django.
Unit test to verify the FastAPI route.
