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.
