aiohug

Tasks:

• Unpack aiohttp request to arguments with annotations

• Validate handlers arguments

• Generate swagger specification

Examples

Run ping pong application

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

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

Body with schema

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

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

Why aiohug?

It’s just hug API implementation for aiohttp

TODO:

• don’t pass default arguments

• default websocket handler with ping/pong and schemas support

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)])
