AIOHTTP Integration

This guide covers how to use FastOpenAPI with AIOHTTP (an asynchronous HTTP framework).

AIOHTTP applications are usually built with an aiohttp.web.Application and run using aiohttp.web.run_app. FastOpenAPI provides an AioHttpRouter to integrate with this.

Setup

Make sure you have installed FastOpenAPI:

pip install fastopenapi

or

pip install fastopenapi[aiohttp]

Hello World

from aiohttp import web
from pydantic import BaseModel
from fastopenapi.routers import AioHttpRouter

app = web.Application()
router = AioHttpRouter(app=app)

class HelloResponse(BaseModel):
    message: str

@router.get("/hello", tags=["Hello"], response_model=HelloResponse)
async def hello(name: str):
    """Say hello from AIOHTTP"""
    return HelloResponse(message=f"Hello, {name}! It's aiohttp!")

if __name__ == "__main__":
    web.run_app(app, host="127.0.0.1", port=8000)

Project Example

See example for this framework in the examples/aiohttp/ directory of the repository.
