It is again, time to apply what you learned

in the last course sections.

We did learn about sending HTTP requests

and we did learn about forums and handling user input.

In this course section, we'll continue working

on this food order application

on this food delivery application

on which we started working a couple

of sections ago already.

And we are going to add a forum

and we are going to add HTTP requests

because this course section is

about applying what we learned

to this food order app.

And therefore we are going to add a basic checkout form

where we can enter our name and address.

Once we click on the order button

we also then want to submit that entered data to a backend.

So to a server with the HTTP request

we probably also want to validate the user input

on the client before we submit it.

And we also want to fetch some data

from a server, from a backend.

We want to fetch the meals data.

So the data here for these dummy meals which we got

which is currently hard-coded into the JavaScript files

that data should move

to a backend as well and should be fetched from there.

Now, when I say backend, I still mean Firebase of course,

we used this as a dummy backend before

and we can still use it here.

Here, I will use my existing project

which I got and I'll use the real time database there.

If you create a new project make sure

that you also do start with the real time database.

And of course, make sure that you did go

through the HTTP section and so on.

There I'll clear any existing data which I have.

And you wanna make sure that

under rules you have read and write set to true

so that you can send requests to that database successfully.

Now how to work with the database.

That is something I did show before

in the HTTP section.

Now in this module

we are going to implement these features here

step by step together.

But this also is a great chance

for you to practice what you'll learn.

So definitely try that on your own first

try implementing all those features

on your own first.

Move that dummy data to Firebase manually.

You can add data manually here to Firebase.

So move that dummy data to Firebase.

And once the data is there

implement these three main features

to this food delivery app, all your own.

Try it on your own first and thereafter

from the next lecture on,

you can check my approach to compare it to yours

to solve problems.

If you got stuck in between

and to then simply build this together with me.
