Implement `aiohttp.web`_ `OpenAPI 3`_ server applications with schema first

approach.

As well as bunch other utilities to build effective server applications with

`Python`_ 3 & `aiohttp.web`_.

* Works on `Python`_ 3.8+

* Works with `aiohttp.web`_ 3.8.1+

* BSD licensed

* Source, issues, and pull requests `on GitHub

.. _`OpenAPI 3`: https://spec.openapis.org/oas/v3.0.3

.. _`aiohttp.web`: https://docs.aiohttp.org/en/stable/web.html

.. _`Python`: https://www.python.org/

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.

.. code-block:: python

    from pathlib import Path

    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", "[email protected]"

            )

            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.

.. _`FastAPI`: https://fastapi.tiangolo.com

.. _`flask-apispec`: https://flask-apispec.readthedocs.io

.. _`aiohttp-apispec`: https://aiohttp-apispec.readthedocs.io

.. _`connexion`: https://connexion.readthedocs.io

.. _`pyramid_openapi3`: https://github.com/Pylons/pyramid_openapi3

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``,

.. code-block:: python

    @operations.register

    class UserView(web.View):

        async def get(self) -> web.Response: ...

.. _`class based views`: https://docs.aiohttp.org/en/stable/web_quickstart.html#aiohttp-web-class-based-views
