S… Speaker 1 (255. Module Introduction)

Thus far in our application,

0:04

S… Speaker 1 (255. Module Introduction)

we always worked in the browser only.

0:06

S… Speaker 1 (255. Module Introduction)

That means that we control all our data with Angular,

0:09

S… Speaker 1 (255. Module Introduction)

we store our data somewhere in memory in the browser.

0:12

S… Speaker 1 (255. Module Introduction)

And it also means that whenever we restart the application,

0:15

S… Speaker 1 (255. Module Introduction)

all our data is gone.

0:17

S… Speaker 1 (255. Module Introduction)

It also means that we can't persist data anywhere.

0:21

S… Speaker 2 (255. Module Introduction)

And of course,

0:22

S… Speaker 1 (255. Module Introduction)

a typical requirement of an application you're building would be that the

0:26

S… Speaker 1 (255. Module Introduction)

front end,

0:27

S… Speaker 1 (255. Module Introduction)

so the part that runs in the browser,

0:29

S… Speaker 1 (255. Module Introduction)

which is your Angular app,

0:30

S… Speaker 1 (255. Module Introduction)

that this does not work standalone,

0:32

S… Speaker 1 (255. Module Introduction)

but that it is able to communicate to some server,

0:35

S… Speaker 1 (255. Module Introduction)

to store data there,

0:37

S… Speaker 1 (255. Module Introduction)

to fetch data from there,

0:39

S… Speaker 1 (255. Module Introduction)

to do whatever you need to do in your application.

0:42

S… Speaker 1 (255. Module Introduction)

And that is exactly what we'll have a look at in this module.

0:45

S… Speaker 1 (255. Module Introduction)

We'll learn how Angular communicates with a backend,

0:49

S… Speaker 1 (255. Module Introduction)

with a database and so on.

0:51

S… Speaker 1 (255. Module Introduction)

You'll learn how to send HTTP requests and also

0:55

S… Speaker 1 (255. Module Introduction)

how to transform data if you need to.

0:57

S… Speaker 1 (255. Module Introduction)

You might remember that observables section where I gave you a first

1:01

S… Speaker 1 (255. Module Introduction)

introduction to that.

1:02

S… Speaker 1 (255. Module Introduction)

Now we'll take a closer look.
