A sorta familiar HTTP framework.
Project description
Responder: a familiar HTTP Service Framework for Python
Powered by Starlette. That async declaration is optional. View documentation.
This gets you a ASGI app, with a production static files server pre-installed, jinja2 templating (without additional imports), and a production webserver based on uvloop, serving up requests with gzip compression automatically.
Testimonials
"Pleasantly very taken with python-responder. @kennethreitz at his absolute best." —Rudraksh M.K.
"ASGI is going to enable all sorts of new high-performance web services. It's awesome to see Responder starting to take advantage of that." — Tom Christie author of Django REST Framework
"I love that you are exploring new patterns. Go go go!" — Danny Greenfield, author of Two Scoops of Django
"Love what I have seen while it's in progress! Many features of Responder are from my wishlist for Flask, and it's even faster and even easier than Flask!" — Luna C.

Installing Responder
Install the latest release:
$ pipenv install responder --pre
✨🍰✨
Or, install from the development branch:
$ pipenv install -e git+https://github.com/kennethreitz/responder.git#egg=responder
Only Python 3.6+ is supported.
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.textsends back unicode, while settingresp.contentsends back bytes. - Setting
resp.mediasends back JSON/YAML (.text/.contentoverride this). - Case-insensitive
req.headersdict (from Requests directly). resp.status_code,req.method,req.url, and other familiar friends.
Ideas
- Flask-style route expression, with new capabilities -- all while using Python 3.6+'s new f-string syntax.
- I love Falcon's "every request and response is passed into to each view and mutated" methodology, especially
response.media, and have used it here. In addition to supporting JSON, I have decided to support YAML as well, as Kubernetes is slowly taking over the world, and it uses YAML for all the things. Content-negotiation and all that. - A built in testing client that uses the actual Requests you know and love.
- The ability to mount other WSGI apps easily.
- Automatic gzipped-responses.
- In addition to Falcon's
on_get,on_post, etc methods, Responder features anon_requestmethod, which gets called on every type of request, much like Requests. - A production static file server is built-in.
- Uvicorn built-in as a production web server. I would have chosen Gunicorn, but it doesn't run on Windows. Plus, Uvicorn serves well to protect against slowloris attacks, making nginx unnecessary in production.
- GraphQL support, via Graphene. The goal here is to have any GraphQL query exposable at any route, magically.
- Provide an official way to run webpack.
