I'm making a very light-weight internal network service, and am using the amazing flask, as it's excellent for prototyping such things.
However, I feel like it's a little over-weight for the simplicity of the task. So, out of curiosity, I'm trying to make a flask-alike server and WSGI microframework which has just enough for these types of projects.
It's not intended to replace flask, obviously. There's no point.
But it is intended that for things like this which don't need a templating language, or any of that, it should be close enough to flask that I can drop this in, and with minimal changes have it running very quickly.
very very very initial alpha. For templating, it's using pythons string.format instead of jinja2.
Routes currently don't use variables, but are just a plain lookup.
static files seem to be (basically) working.
All that said:
It's quite fast. (Ha, no surprise, with all those caveats...)
- the 'request' object is just the pure WSGI environ at the moment.
- MIME types for templates (and static files)
- routing <with><vars>
basic speed comparison:
just a very quick comparison, in a dead simple 2-views monitoring app using apache bench to get 10000 requests, both running with the gevent server:
obviously, these numbers are not going to always hold true, but it does at least prove that for very very simple apps that don't need full flask power, a flask-subset may well be enough, and heck of a lot faster. More benchmarks are needed to see which parts of flask are being slow here - it could be that we can add jinja2 back in if needed and still get good improvements. Then again, it could be that just replacing jinja2 with simpler string.formatting is enough to get flask way way faster - which would be a nice thing to know. :-)
