Goals:
=====

- Unpack aiohttp request to arguments with annotations
- Validate handlers arguments
- Generate swagger specification

Examples
========

Run ping pong application
-------------------------

.. code:: python

from aiohttp import web
from aiohug import RouteTableDef

routes = RouteTableDef()


@routes.get("/ping/")
async def ping():
return "pong"


app = web.Application()
app.add_routes(routes)


if __name__ == "__main__":
web.run_app(app)

There is no more ``request`` object in handler.

Arguments from path and query
-----------------------------

.. code:: python


@routes.get("/hello/{name}/")
async def hello(name: fields.String(), greeting: fields.String() = "Hello"):
return {"msg": f"{greeting}, {name}"}

Body with schema
----------------

.. code:: python

from aiohttp import web
from aiohug import RouteTableDef

routes = RouteTableDef()

class PayloadSchema(Schema):
count = fields.Int()

@routes.get("/")
async def with_body(body: PayloadSchema()):
return body

app = create_app()
app.add_routes(routes)

client = await test_client(app)
resp = await client.get("/", json={"count": "5", "another": 7})

assert await resp.json() == {"count": 5}

Another shortcuts
-----------------

.. code:: python

@routes.post("/ping/")
async def ping():
return 201, "pong"

Swagger
-------

Use `aiohug_swagger` package.


Why aiohug?
===========

It's just hug_ API implementation for aiohttp

.. _hug: https://github.com/timothycrosley/hug

TODO:
=====

- don’t pass default arguments
- default websocket handler with ping/pong and schemas support

.. code:: python

ws = aiohug.WSHandler()


@ws("hello") # match message by `type` field
async def hello(name: str, greeting: str="Hi"):
""" Just send {"type": "hello", "name": "Lucy", "greeting": "Hi"} """
return {"text", f"{greeting}, {name}"}


app = create_app()
app.add_routes([web.get('/ws', ws)])
