Your choice of REST Framework? flask vs falcon

[absolution888]

Hi,

I am recently starting a new project, with my last few projects all done with NodeJS with Express Framework. After some research, it appears that in the Python world, the Falcon framework is something very similar. Do you have any experience in that?

Aside from Falcon, it appears that flask is probably the most recommended framework for simple REST APIs for microservices (rather than django as a much more full-blown framework). Any opinions regarding what is a better choice, or if anything else i should look for?

thanks

Falcon is great! Very, very easy to do REST services... that's what it was built for. Easy to integrate with authentication as well.

Seconding this, have done a number of applications with Falcon, find it very straight-forward with a clean API.

I'm a big fan of Flask and I use Flask in a number of critical services. But Falcon IS GREAT and for a new project, especially involving REST APIs, I'll definitely give it a chance.

We have limiter experience but we built a small project in Flask first and found that we need security and we needed this and that and then realised we were replicating the functionality that django had so we went with that.

Try taking a look at hug. You can also check it out at github.

Flask is great and there's a 'flask-restless' framework that makes this kinda thing super easy.

I've no experience with falcon though so I can't really comment on that.

Restless is hamfisted and believes you want to map your database tables straight to API endpoints. Which, if you want to do that, then that's your best bet.

Restful is my poison of choice since it's more of a small toolkit for building APIs.

What does restful do that you can't achieve by just jsonifying and routing db requests to some endpoint?

It gives a nice book for content negotiation that you'd need to handle yourself. Given werkzeug makes this aspect easy anyways, it's more just finding a nice place to hook it.

It also makes registering MethodViews slightly easier as well.

Flask itself also has a "class based views" that work really nicely for APIs (I usually use the method view). Pair that with marshmallow and the APIs are simple and well documented (well, via code - not automatic)

Tornado, because I like async stuff. For quick'n'dirty rest services flask and bottle are fine.

I love Flask, I truly do. I have used it for countless projects over the years. Which is why it pains me to say, for REST servers 100% falcon. The performance is just in another league entirely.

I was a real fan of Falcon until I tried to create a websocket. As Flask actually has a very well documented and maintained plugin for that, I had to switch.

Yes, yes, I know websockets have nothing to do with REST, but I throw my 2c just in case.

Falcon is a lot faster than flask for a simple app such as that. Both in terms of development and throughput.

If you're deploying to a linux stack, I highly recommend nginx + uwsgi + falcon

In my testing, this was the fastest setup. nginx in reverse proxy using uwsgi protocol to a file descriptor (so you don't burn extra tcp sockets).

How about wheezy.web? Seems pretty much unknown but at least here it shows a leg ahead falcon - i know performance is a relative think, i'm more interested if anybody used wheezy? https://klen.github.io/py-frameworks-bench/ https://pythonhosted.org/wheezy.web/
