00:00:00,061 --> 00:00:04,041
To keep our code DRY, let's add
a function that prints error messages.

2
00:00:05,447 --> 00:00:08,459
I've added a snippet in the teacher's
notes, so you can just copy and paste.

3
00:00:12,325 --> 00:00:14,767
We can call this function
in all of our handlers and

4
00:00:14,767 --> 00:00:17,283
replace the statements
that are currently there.

5
00:00:19,935 --> 00:00:21,280
So in our try block.

6
00:00:24,318 --> 00:00:25,713
PrintError.

7
00:00:29,516 --> 00:00:34,317
Save, Same here in our on method.

8
00:00:57,630 --> 00:01:00,312
And we'll test this out by
running the code again.

9
00:01:00,312 --> 00:01:03,801
We just get our error message, great.

10
00:01:03,801 --> 00:01:08,418
HTTP provides us with status codes
that indicate the status of a request.

11
00:01:08,418 --> 00:01:12,419
When a request is completed without issue,
we'll get a status of 200.

12
00:01:12,419 --> 00:01:15,655
Maybe there was a server error,
which will give us a 500 error.

13
00:01:18,453 --> 00:01:22,103
Maybe the endpoint moved,
and we'll get 301.

14
00:01:22,103 --> 00:01:25,770
If the endpoint is incorrect,
we'll get a status code of 404 Not Found.

15
00:01:28,030 --> 00:01:32,260
So far, we've assumed that each
API response will be okay.

16
00:01:32,260 --> 00:01:35,300
Let's handle all the status
codes that aren't 200.

17
00:01:35,300 --> 00:01:39,340
If the status code is 200,
we want to continue.

18
00:01:39,340 --> 00:01:42,680
If not,
we want to print out an error message.

19
00:01:42,680 --> 00:01:46,522
The message will say, there was an error
getting the profile for the username,

20
00:01:46,522 --> 00:01:48,080
with the status code at the end.

21
00:01:49,270 --> 00:01:53,957
Let's create a status code error,
by creating a new error object.

22
00:01:53,957 --> 00:01:57,797
Inside the response callback,
we'll check if the status code equals 200.

23
00:02:05,988 --> 00:02:11,053
If the status code isn't 200,
we'll create a new error to handle this.

24
00:02:11,053 --> 00:02:17,329
We'll first create an error message where
we'll interpolate the HTTP status code.

25
00:02:19,604 --> 00:02:24,538
And we'll need to include HTTP in our
file, using require to do this.

26
00:02:27,693 --> 00:02:32,182
Actually copy this,
remove the S in both places.

27
00:02:36,327 --> 00:02:39,925
Now on a new line,
create a new error object.

28
00:02:54,160 --> 00:03:01,258
And now, we use printError,
print out that statusCodeError.

29
00:03:06,806 --> 00:03:08,357
Save.

30
00:03:15,590 --> 00:03:17,754
There we have it.

31
00:03:17,754 --> 00:03:24,408
Our error message with the correct
status code appended to the end.

32
00:03:24,408 --> 00:03:27,410
Well done, you've gotten acquainted
with some of the errors and

33
00:03:27,410 --> 00:03:29,160
error types in Node.

34
00:03:29,160 --> 00:03:32,774
Take your learning further by getting
familiar with the different possible

35
00:03:32,774 --> 00:03:34,249
errors in the documentation.

36
00:03:34,249 --> 00:03:37,783
When you get an error in your code,
do your best to track where and

37
00:03:37,783 --> 00:03:39,780
why it is occurring.

38
00:03:39,780 --> 00:03:41,839
This will help you improve
your debugging skills and

39
00:03:41,839 --> 00:03:43,820
getting a better understanding
of the language.
