So that's it for the HTTP module.

0:05

S… Speaker 1 (280. Wrap Up)

Quite a long module where you learned a lot about the Angular HTTP

0:09

S… Speaker 1 (280. Wrap Up)

client.

0:10

S… Speaker 1 (280. Wrap Up)

Now the most common task you will do is of course that you send requests

0:14

S… Speaker 1 (280. Wrap Up)

by using post,

0:15

S… Speaker 1 (280. Wrap Up)

get and so on by adding a URL,

0:17

S… Speaker 1 (280. Wrap Up)

possibly a request body and maybe some request headers.

0:21

S… Speaker 1 (280. Wrap Up)

This will be your bread and butter thing and therefore this is the task

0:25

S… Speaker 1 (280. Wrap Up)

you should practice and you should feel confident about.

0:27

S… Speaker 1 (280. Wrap Up)

Always remember that

0:31

S… Speaker 1 (280. Wrap Up)

these methods like get and post give you back an observable to which you have

0:35

S… Speaker 1 (280. Wrap Up)

to subscribe to actually kick off the request and to send it since

0:39

S… Speaker 1 (280. Wrap Up)

it is an observable you can use operators rxjs operators

0:43

S… Speaker 1 (280. Wrap Up)

to transform the data log data catch errors or

0:47

S… Speaker 1 (280. Wrap Up)

whatever you want to do but ultimately you need to subscribe and

0:52

S… Speaker 1 (280. Wrap Up)

you can do this in a service or in a component depending on where you need to work

0:56

S… Speaker 1 (280. Wrap Up)

with the response and in the subscribe method

0:59

S… Speaker 1 (280. Wrap Up)

you pass in a function to handle the data you get back and possibly also

1:03

S… Speaker 1 (280. Wrap Up)

an error handling function like this one.

1:06

S… Speaker 1 (280. Wrap Up)

This is how you generally work with HTTP requests.

1:10

S… Speaker 1 (280. Wrap Up)

Now you got advanced features like the possibility of setting

1:14

S… Speaker 1 (280. Wrap Up)

what you wanna observe if you are interested in

1:19

S… Speaker 1 (280. Wrap Up)

the response or just the body of the response

1:23

S… Speaker 1 (280. Wrap Up)

or all the events,

1:25

S… Speaker 1 (280. Wrap Up)

which type of data should be returned.

1:27

S… Speaker 1 (280. Wrap Up)

You can set query perims and you have that very useful features

1:31

S… Speaker 1 (280. Wrap Up)

of intersetters,

1:33

S… Speaker 1 (280. Wrap Up)

which can really help you save time and code if you have

1:37

S… Speaker 1 (280. Wrap Up)

some header that needs to be appended to every outgoing request,

1:40

S… Speaker 1 (280. Wrap Up)

for example.

1:41

S… Speaker 1 (280. Wrap Up)

And as I already mentioned,

1:43

S… Speaker 1 (280. Wrap Up)

we'll see intersetters in action again later in the course once we add authentication.

1:48

S… Speaker 2 (280. Wrap Up)

For now,

1:48

S… Speaker 2 (280. Wrap Up)

this is it.

1:49

S… Speaker 1 (280. Wrap Up)

Let's now move on to the course project and practice using these HTTP

1:54

S… Speaker 1 (280. Wrap Up)

requests there.
