[0:00] flask Django or fast API this is the
[0:03] question you should be asking yourself
[0:04] if you're interested in Python web
[0:06] development in this video I'm going to
[0:08] break down everything you need to know
[0:09] about these three different Frameworks
[0:11] and tell you which one you should pick
[0:13] depending on your use case now let's get
[0:16] started with flask this is a lightweight
[0:18] wsgi web application framework that's
[0:21] easy to get started with and highly
[0:23] customizable it's a minimalist framework
[0:25] with extendable features and it's great
[0:27] for building small to mediumsized apps
[0:29] like micro Services next we move on to D
[0:31] Jango now this is a highlevel python web
[0:34] framework that comes with a ton of
[0:35] features out of the box it includes an
[0:38] omm forms authentication routing and
[0:41] more Jango is ideal for handling complex
[0:44] web applications because of its
[0:46] conventional project structure and all
[0:48] of the features that are built into the
[0:49] framework saving you a ton of time
[0:51] lastly we move on to fast API now this
[0:54] is a modern high performance web
[0:56] framework for building apis with
[0:58] standard python type it has support for
[1:01] asynchronous programming automatic data
[1:03] validation and generation of open API
[1:06] documentation this is great for quickly
[1:08] building apis that are self-documenting
[1:10] and really fast in performance so now
[1:13] that we have an overview of these
[1:14] various Frameworks I'm going to start
[1:16] going through some very specific
[1:17] comparison criteria so you can
[1:19] understand exactly which one to pick
[1:21] depending on your use case however if
[1:23] you are going to build out a project
[1:25] using one of these Frameworks you're
[1:27] probably going to want to be utilizing
[1:28] an IDE and not not just because idees
[1:31] can make your life so much easier but
[1:33] because experience with them is actually
[1:35] something a lot of recruiters are
[1:36] looking for now there's all kinds of
[1:38] basic code editors to pick from but if
[1:40] you really want to get to the
[1:41] professional level then you should
[1:42] utilize Jeet brains IDE which is the
[1:45] sponsor of this video whether you're
[1:47] working in Python go rust Java you name
[1:51] it Jeet brains has a fully featured
[1:53] professional IDE for you these idees
[1:55] offer the best performance and speed and
[1:57] have impressive user interfaces take
[2:00] advantage of integrated debuggers code
[2:02] analysis quick fixes and incredible AI
[2:05] assistance that supercharge your
[2:06] workflow not to mention features like
[2:08] instant search and navigation and an
[2:10] insane amount of plugins to customize
[2:12] your environment as you scale up and
[2:14] work on larger and larger projects the
[2:16] importance of an IDE becomes clear you
[2:19] should really start building strong
[2:20] habits Now by utilizing professional jet
[2:23] brains idees and taking advantage of
[2:25] these powerful tools from the link in
[2:27] the description so let's start comparing
[2:29] these Frameworks beginning with ease of
[2:31] learning now we start with flask this is
[2:34] by far the easiest to learn and in just
[2:36] a few minutes you can have a fully
[2:37] functioning API or website it's very
[2:40] simple and easy to use there's not a lot
[2:42] of setup or a ton of settings that you
[2:44] need to go through and if you're just
[2:45] trying to build something very simple I
[2:47] definitely recommend sticking with flask
[2:50] moving on from that we go to fast API
[2:52] now fast API is more of an intermediate
[2:55] difficulty there are more Concepts that
[2:56] you need to learn you need to understand
[2:58] asynchronous programming and it's
[3:00] helpful to also understand pantic and
[3:02] how you use the python type hint system
[3:05] fast API is a lot more powerful and it
[3:07] can provide automatic documentation and
[3:09] data validation which can be really
[3:11] really helpful but it does take a little
[3:13] bit longer to set up and can be slightly
[3:15] more complicated lastly we move on to D
[3:17] Jango now this is by far the most
[3:20] complicated because it has so many
[3:21] features built in that means just to get
[3:23] a simple D Jango website set up can
[3:25] actually take 20 or 30 minutes if you're
[3:28] learning this completely from scratch
[3:29] it's definitely going to take you a few
[3:31] days or a few weeks to really understand
[3:33] all of the different features and how
[3:34] all of the components work together that
[3:37] said D jeno is definitely worth learning
[3:39] and if you're going to be building
[3:40] something more complicated and with a
[3:41] lot of data I definitely recommend going
[3:44] down that path just understand it will
[3:46] take you a little bit longer as there's
[3:47] a lot of things you need to learn to get
[3:49] started with Jango so now we can get
[3:51] into performance starting with flask now
[3:54] flask has good performance overall but
[3:56] it's not the best for high load
[3:58] applications the reason for that is it's
[4:00] built in a synchronous context meaning
[4:03] it's not going to handle multiple
[4:04] requests at the exact same time like
[4:06] some other web Frameworks next we have
[4:09] fast API now fast API out of all of the
[4:12] Frameworks here is by far the fastest
[4:14] it's Superior to all of them and the
[4:16] reason for that is it's built
[4:17] asynchronously meaning it can scale and
[4:19] it can handle multiple requests at the
[4:21] exact same time lastly we move on to D
[4:24] Jango now Django is the slowest of the
[4:26] three Frameworks due to its
[4:28] comprehensive nature however it is still
[4:30] very reliable for large applications and
[4:32] a lot of huge companies still use Django
[4:35] despite the fact that it's not the
[4:36] fastest out there in summary if you're
[4:38] really looking for the absolute best
[4:40] performance and you're building
[4:41] something like an API then definitely
[4:43] choose fast API but for most of you this
[4:46] isn't going to matter a ton so simply
[4:48] pick the one that's easiest to use or
[4:50] best suited for your project so now
[4:52] we're going to dive into the use cases
[4:54] starting with flask now flask for me is
[4:56] what I use when I want to build
[4:57] something really quickly and I don't
[4:59] want to deal with a ton of configuration
[5:01] or spend a lot of time setting up a
[5:02] server if I need a really fast web
[5:05] server if I want to get something done
[5:06] in just a few minutes I'll definitely
[5:08] turn to flask and even for slightly
[5:10] larger hobby projects flask is still
[5:12] totally fine personally for me it's not
[5:14] something I would use in production
[5:16] unless it was doing a really simple task
[5:18] and that's because there are better more
[5:20] performant options out there but a lot
[5:22] of times in my development environment
[5:23] I'll need a simple API and I'll turn to
[5:26] flask because I know it's the fastest
[5:28] for me to get something set up with it's
[5:30] great to start with if you're a complete
[5:31] beginner it's good for prototyping and
[5:33] you can really use it to learn the
[5:35] fundamentals of web development next we
[5:37] move on to D Jango now Jango is best
[5:39] when you're building a large monolithic
[5:41] application and you need a lot of
[5:43] built-in features like a CMS
[5:45] authentication and om Etc now it's worth
[5:49] noting that with a framework like flask
[5:51] you can actually have extensions or
[5:52] additional python packages they provide
[5:55] some of the same functionality but it's
[5:57] not as conventional to use them and it
[5:59] can get a a little bit messy when you're
[6:00] building a really large app so that's
[6:02] personally why I prefer D Jango Django
[6:05] has a lot of settings and configuration
[6:07] built in a lot of things you already
[6:09] know how to do because it's simply built
[6:11] into the framework when you start
[6:12] building something larger and you maybe
[6:14] have multiple developers on your team
[6:16] it's a lot easier to work with something
[6:18] that has the conventions built in like d
[6:20] Jango and all of the features already
[6:22] wrapped into the framework Jango is
[6:24] really good when you're dealing with a
[6:25] lot of data it has again something
[6:27] called an OM which is an object
[6:29] relational mapping and it allows you to
[6:31] utilize databases just like a normal
[6:33] python object which can make it really
[6:35] easy to do development and manage large
[6:37] amounts of data that said it also has
[6:39] all of that data that you can add to an
[6:41] admin panel so you have a built-in CMS
[6:44] and overall it's just better when you're
[6:45] dealing with a lot of data and you have
[6:47] these larger applications now lastly we
[6:50] move on to fast API fast API is really
[6:53] the choice to go with if you're trying
[6:54] to build a high performant API now with
[6:57] both flask and Django you can build API
[6:59] as well or you can just build a normal
[7:01] website where you're rendering HTML and
[7:03] pages but really if you want the fastest
[7:06] API you can possibly have then fast API
[7:08] is the one to go with it has automatic
[7:10] data validation automatic documentation
[7:13] which is super super helpful especially
[7:15] as you scale up and it has asynchronous
[7:17] programming built in which is really
[7:18] what provides it all of that speed so
[7:21] overall flask for something simple
[7:23] prototyping getting a hobby project up
[7:25] and running Jango for something a little
[7:27] more professional where you need those
[7:28] built-in features and then fast API when
[7:31] you want a high performance scalable API
[7:33] so now we move on to community and
[7:35] ecosystem now all three of these are
[7:37] very large well-known python Frameworks
[7:40] they have a huge Community behind them
[7:42] and all of them have additional
[7:43] extensions add-ons plugins Etc that you
[7:47] can add to have additional functionality
[7:49] in each framework for example something
[7:51] like flask even though it doesn't have a
[7:53] ton of features built in there's all
[7:55] kinds of packages you can install they
[7:57] provide that additional functionality
[7:59] for example you want authentication in
[8:01] flask you can simply install a package
[8:03] and now you have flask authentication
[8:05] you just need to do a little bit of
[8:07] configuration same thing for Django same
[8:09] thing for fast API so I wouldn't pick
[8:11] one of these three packages or one of
[8:13] these three Frameworks sory simply
[8:15] because they have a larger Community or
[8:16] ecosystem all of them are very wellknown
[8:19] all kinds of resources on the internet
[8:21] and they're used for very large projects
[8:23] some of which you've probably interacted
[8:25] with so now we're going to get into job
[8:27] demand and which of these you should
[8:28] learn if you are looking to land a
[8:30] developer role now bluntly Django is
[8:32] going to be the most popular here and
[8:34] it's going to show up in the most job
[8:36] requirements that's because this is the
[8:38] larger of the Frameworks it's used for a
[8:40] lot of larger or midsize companies and
[8:42] this is really just what a lot of people
[8:44] go to when they're trying to build a
[8:46] website or some kind of backend service
[8:48] with python so if you are looking to
[8:50] land a roll simply learn Jango that's
[8:52] going to be your best bet not to say
[8:54] that flask and fast API don't have some
[8:56] demand in the market they do and they're
[8:58] increasingly popping up especially for
[9:00] the smaller companies or startups but
[9:02] most of the time you're going to be
[9:03] seeing Jango listed as that primary
[9:05] framework overall I would say it's worth
[9:07] it just to learn them all D Jango will
[9:09] definitely take you the most amount of
[9:11] time but picking up something like Fast
[9:13] API or flask is going to be pretty fast
[9:15] and it can have an added benefit when
[9:17] you are applying to jobs so there you
[9:19] are that's my breakdown of flask Jango
[9:21] and fast API flask for simple web apps
[9:24] where you're prototyping or building
[9:26] something quickly D Jango for more
[9:28] complicated dated driven applications
[9:30] and fast API for building that fast
[9:32] scalable API with python if you enjoyed
