Allin is an experimental asynchronous web framework.
I didn't expect this framework to be used in a production environment, as it's still in the early stages of development. Not sure when this framework can be used in production 😬
You can help this project get better by creating an issue or PR. Thank you for your time!

Allin
is heavily inspired by Flask, Starlette & Falcon.
I'm just curious 🧐
Yup, I'm curious about how a web application based on ASGI works.
It may not yet fully comply with the ASGI application specifications as documented. But, for the main features like route mapping, HTTP responses, error handling, parsing the request body it's there.
...and I want to build my own framework from scratch so I know how the application works.
Literally, the "framework parts" weren't built from scratch as I also used third party modules and some "parts from other sources" were used as references.
This is part of the journey

Extension

Websocket Support
- Global variables. (It means, you can access the
app
andrequest
object instances globally) - Error handling
-
JSON
andMessagePack
requests are supported out of the box (thanks to msgspec) - Form Data Support (
application/x-www-form-urlencoded
ormultipart/form-data
) - Decorator shortcuts such as
@get
,@post
,@put
, etc. are available. - Nesting routers
Here is an example application based on the Allin
framework and I'm sure you are familiar with it.
from allin import Allin, JSONResponse
app = Allin()
@app.route("/")
async def index():
return JSONResponse({"message": "Hello World!"})
👇 Explanation
- The
app
variable is the ASGI application instance. - And we create an endpoint with the route
/
on the lineapp.route(...)
- Then we add the
index()
function to handle the/
route. - And the handler function will return a JSON response with the content
{"message": "Hello World!"}
That's it! looks familiar right?
