At this point in the course

we already learned a lot about React,

though I will say there also is more left to be learned.

But everything we learned up to this point

was about React doing things

inside of our app, in the browser.

And of course, that is why we do use React.

That is its main job

but we also only worked with local data up to this point.

So we only played around with dummy data

which was always just managed and stored in the browser.

In this course section, we are going to dive

into how you may connect your React Application

to a backend, to a database.

Because of course, many applications

probably all applications need to fetch data

from a database or store some data in a database eventually.

No matter if we're talking about

users that need to be created

and stored and locked in, or if we're talking about products

that need to be loaded or anything like that.

And therefore this section

is about establishing such a connection.

And it is about Sending Http Requests

from inside our React App to a backend.

And specifically we are going to learn

how exactly React Apps do interact with Databases?

Because whilst it's simple, as you will learn

it will not necessarily work as you expect it to work.

You will learn how you can send Http Requests

and work with responses, which you get back.

And we're going to have a look at how we can handle Errors

and Loading States in our application.
