Responder is a web framework for Python. It is highly experimental and is not recommended for production use. I
personally consider this project to be an academic exercise, and recommend reading through the code, however!

I think it was a little ahead of its time. FastAPI is a more mature and production-ready alternative.

The Basic Idea

The primary concept here is to bring the niceties that are brought forth from both Flask and Falcon and unify them into a single framework, along with some new ideas I have. I also wanted to take some of the API primitives that are instilled in the Requests library and put them into a web framework. So, you’ll find a lot of parallels here with Requests.

• Setting resp.content sends back bytes.
• Setting resp.text sends back unicode, while setting resp.html sends back HTML.
• Setting resp.media sends back JSON/YAML (.text/.html/.content override this).
• Case-insensitive req.headers dict (from Requests directly).
• resp.status_code, req.method, req.url, and other familiar friends.
• The async keyword is optional for route functions. You must use await within any route that is reading from the network.

Status

I wanted to reboot this project, but I think FastAPI is a better choice for most people. I recommend using that instead.

Honestly, I wrote this code in a month while I was taking perscription ADD meds, years ago, and I don’t remember much about it. I recommend reading through the code, though!
