Ask HN: Django or Flask as first web framework?

You can never go wrong with Django. It comes with enough batteries included to get you up and running with complex projects quickly. Plus, there's a lively ecosystem of useful libraries built on top on Django that make complex tasks a breeze. If you want to built useful webapps quickly, Django is the way to go.

The assertion that Flask gives you a better look under the hood is, in my opinion, incorrect. With Flask, you get almost nothing out of the box besides some basic URL routing and request handing. For most web development tasks, that's not enough. So you end up adding an ORM, a template engine, a session handling library, etc. on top. Eventually you end up with a set of libraries that have as much "magic" to them as your standard Django install, except now they're loosely held together by duct tape. Just take a look at SQLAlchemy, WTForms or Jinja2 -- three libraries that are often used with Flask -- and tell me whether they feel less like magic than Django's equivalents. Plus, now you have to look up documentation for three libraries in three different places, keep up with their developments separately, and get used to three different coding conventions. It gets complex very fast.

As adambard mentioned, Flask is a very effective tool when you want to do something highly nonstandard and rolling your own framework is your only option. For 9 out of 10 webapps, though, Django is the right answer.

Either one is great. I started with Django and now prefer Flask; unless you are starting out with an enormous project I agree with the recommendations you have received--you will get a better sense of what's happening under the hood with Flask.

I don't like learning from videos so can't help you there, but http://djangobook.com is awesome for learning Django, and the Flask documentation is sufficient too.

I recommend Django because it's much more widely used. You'll find more write-ups, Stack Overflow questions, podcasts and conference videos. Instagram uses it. Disqus uses it. There's just a ton of help out there for a new developer.

While I agree that a lot of what Django does seems like "magic", getting to know how that magic works as you get more intimate with the framework will make you a better developer in the long run - so you can start writing your own magic.

I think if you end up in development as a career, Django is going to be used incredibly more often than Flask.

In the end, you will learn the internals either way. If you start with Flask, you'll still have to learn about Django internals.

Start with Django (and you'll probably never switch to Flask).

Depends what you want to build.

Flask is better suited to apps that are a) small and single-purpose, or b) highly nonstandard.

Django has a lot of stuff built right in, much of which you won't need. But it's nice to have a database abstraction, forms, auth, admin, etc. when you need them. Plus, it's practically a CMS already all by itself, with the nice admin panel.

I'd probably start with Django. The tutorial isn't bad at all: https://docs.djangoproject.com/en/1.4/intro/tutorial01/

Hi Adrian,

I would recommendation is django, but there currently are no good tutorials for it. Kenneth Love (https://twitter.com/kennethlove) is creating django video series that should be available in December.

In the meantime my recommendation is as follows:

1. Make sure you have an understanding of Python before you get into Django or Flask. Do this by taking one (or all) of the following online classes:

a. Udacity.com: http://www.udacity.com/overview/Course/cs101/CourseRev/apr20...

b. Learnpythonthehardway.org (There are video lessons for a price of $29)

c. https://www.edx.org/courses/MITx/6.00x/2012_Fall/about

2. Once you have an understanding of python and can write simple scripts, I recommend the following video courses for web development with Python:

a. Flask: http://www.youtube.com/user/calicoJake (A great Flask video tutorial series)

b. Udacity: http://www.udacity.com/overview/Course/cs253/CourseRev/apr20... (not flask or django, but still good)

c. Django: http://www.kickstarter.com/projects/657368266/getting-starte... (to be released in Dec 2012 or early 2013.

You could start tonight. Master your art, choose your weapon - django or flask - and hit the ground running. oh and have fun.

I started learning Django as my first web framework. If I had to do it over I would have spent a month with Flask, and then moved to Django. Django is a big app, and I found it difficult to build a mental model of its workings. Maybe starting with a smaller framework would have made it easier.
