fastapi is quick way to develop REST API. It can be done with flask or Django but fastapi can do a lot of stuff out of the box. For example, fastapi creates openapi SWAGGER UI on /docs.
from typing import Union
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
def read_root():
return {"Hello": "World"}
@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
return {"item_id": item_id, "q": q}
To start the server, we can use dev server from the application app.py
pip install fastapi
fastapi dev app.py
