As well as bunch other utilities to build effective server applications with Python 3 & aiohttp.web.
Works on Python 3.7+
Works with aiohttp.web 3.8.1+

Quick Start
rororo relies on valid OpenAPI 3 schema file (both JSON or YAML formats supported).
Example below, illustrates on how to handle operation hello_world from openapi.yaml schema file.
from pathlib import Path
from typing import List
from aiohttp import web
from rororo import (
openapi_context,
OperationTableDef,
setup_openapi,
)
operations = OperationTableDef()
@operations.register
async def hello_world(request: web.Request) -> web.Response:
with openapi_context(request) as context:
name = context.parameters.query.get("name", "world")
email = context.parameters.query.get(
"email", "world@example.com"
)
return web.json_response(
{"message": f"Hello, {name}!", "email": email}
)
def create_app(argv: List[str] = None) -> web.Application:
return setup_openapi(
web.Application(),
Path(__file__).parent / "openapi.yaml",
operations,
server_url="/api",
)Schema First Approach
Unlike other popular Python OpenAPI 3 solutions, such as Django REST Framework, FastAPI, flask-apispec, or aiohttp-apispec rororo requires you to provide valid OpenAPI 3 schema first. This makes rororo similar to connexion, pyramid_openapi3 and other schema first libraries.
Class Based Views
rororo supports class based views as well. Todo-Backend example illustrates how to use class based views for OpenAPI 3 servers.
In snippet below, rororo expects that OpenAPI 3 schema contains operation ID UserView.get,
@operations.register
class UserView(web.View):
async def get(self) -> web.Response:
