Okay, so once you are familiar with the key elements of the front end and you are comfortable with
the tutorial of next JS, the tutorial of Vercel, and also the tutorial of Create Llama.
Let's talk a little bit about the key elements in the back end side of the full stack application.
The most important one is fast API.
So this is right now the the most popular framework for creating the back end of web applications with
Python.
So it is not the most popular framework for creating back end web applications.
That is node.
But when we are in the artificial intelligence field, since the artificial intelligence engineers,
the traditional ones, they come from Python.
This is the back end framework that has become more popular for them.
Okay, so right now in the world of Lama index and Lang chain, this is the most popular framework you
are going to find.
And for back end a building in the a full stack application world.
So in order to learn fast API we.
As always, recommend you to go to the.
Let's go to the English version.
Okay.
Let's go to the fast API documentation page and especially to this very quick and easy tutorial they
provide.
We are giving you a notebook.
We are giving you also a code, a project, a coding project in the GitHub repository.
But this is what you are going to build yourself once you, uh, complete the steps of the quick tutorial,
fast API is provided.
You will see how to install fast API in your computer, how to create a very basic back end for one
application, and how to include some of the very basic elements there.
So my recommendation for you is just get comfortable with the basic tutorial of fast API and get familiar
with what you can find in the fast API documentation.
Fast API is a very simple a framework in the basic uh.
In the basic step, it can also be more complex.
But the important thing for you is to understand, you know, the basic parts and get familiar with
what you can find in the documentation page.
So you will be ready to come back here whenever necessary.
Okay.
So go there.
Uh, go to the uh, tutorial if you find any problem, you know, where to go, uh, chat, GPT four,
etc. and once you are comfortable with this, uh, tutorial, we will go to the next step talking about
fast API with long chain.
We will see that in the next lesson.
