What is this?

It's a DIY asynchronous microframework project to further explore Python35+, software architecture, and a few other interesting things. It is composed of a simple HTTP/1.1 async server and the actual framework.

Here are some of the things it demonstrates:

  • Dependency injection and how it affects application design and ease of testing.
  • How to use the comfortable [asyncio.start_server][2] interface to write asynchronous networking code.
  • A naive approach to parsing HTTP requests and routing requests.
  • A first try at the Clean Architecture based on Brandon Rhode's The Clean Architecture in Python. The business logic (parsing requests, routing requests, etc.) doesn't know a thing about IO, meaning, the IO depends on the entity and this dependency happens only one way.

Here's the inspiration behind this project:

This is not production grade code.

It implements only a small subset of HTTP/1.1, it has not been profiled and optimized, and doesn't have any facilities to defend against common web attacks.

However, because it's so small, it can be studied to see how an actual framework works.

Running

To run the example application, just execute it with a Python3.5 interpreter:

python application_example.py
