00:00:00,350 --> 00:00:05,430
Okay so now that we're finished with our
lab, we can clean up those resources.
1

2
00:00:05,430 --> 00:00:09,150
So we need to work backwards like we
normally would so we start off with our
2

3
00:00:09,150 --> 00:00:13,950
federated identity or our identity pool
we need to remove that first, so what we
3

4
00:00:13,950 --> 00:00:22,230
do is we go to the dashboard and then we
click on edit identity pool and then we
4

5
00:00:22,230 --> 00:00:30,199
scroll down to delete identity pool and
then delete that identity pool and
5

6
00:00:30,199 --> 00:00:34,890
that's all we have to do for the
identity pool quite straightforward, with
6

7
00:00:34,890 --> 00:00:37,559
the user pool there's a few things that
we need to do first so we need to go to
7

8
00:00:37,559 --> 00:00:43,129
our domain name and delete that domain
8

9
00:00:44,629 --> 00:00:49,289
which is done and then once we've done
that we can go to our general settings
9

10
00:00:49,289 --> 00:00:56,789
again and delete that pool and we just
need to type in delete and delete that
10

11
00:00:56,789 --> 00:01:02,699
pool okay so that's how easy it is to do
that and of course we go into our s3
11

12
00:01:02,699 --> 00:01:08,640
bucket and we can delete our bucket as
well, so we select our bucket and delete
12

13
00:01:08,640 --> 00:01:18,840
that bucket, I'll just copy the name of
it first, okay and there goes out
13

14
00:01:18,840 --> 00:01:22,530
we've cleaned up everything now we'll
have a look at some of the ways that we
14

15
00:01:22,530 --> 00:01:28,080
can improve the performance of this
JavaScript SDK, okay so there are a
15

16
00:01:28,080 --> 00:01:34,220
number of ways that we can reduce the
size of the SDK for JavaScript and to
16

17
00:01:34,220 --> 00:01:37,829
increase the performance of our
application while it's downloading that
17

18
00:01:37,829 --> 00:01:44,159
and probably the best way would be to
use Webpack or Browserify or whatever
18

19
00:01:44,159 --> 00:01:48,210
you want to use that it's going to
basically look at the import statements
19

20
00:01:48,210 --> 00:01:54,600
on your react.js app or whatever you're
using and basically optimize that for it
20

21
00:01:54,600 --> 00:01:59,490
so that you you're only bringing in what
you need to bring in there is another
21

22
00:01:59,490 --> 00:02:05,340
way and it's specifically for the AWS
SDK for JavaScript it's not for the
22

23
00:02:05,340 --> 00:02:09,569
other SDKs but just for that one which
is quite important because there is the
23

24
00:02:09,569 --> 00:02:13,379
big one
because it has all of the SDKs for all
24

25
00:02:13,379 --> 00:02:15,659
of
the AWS services, so if you're pulling
25

26
00:02:15,659 --> 00:02:21,659
that one in it's a bit big, so we get to
it by going to sdk.amazon.com/builder/js
26

27
00:02:21,659 --> 00:02:27,360
and there's a
link to that in the lab notes so have a
27

28
00:02:27,360 --> 00:02:29,970
look at that when we get there it's
going to have some stuff already
28

29
00:02:29,970 --> 00:02:33,239
pre-selected for us
we're just clear all that for now
29

30
00:02:33,239 --> 00:02:38,670
because all we need is Cognito and s3 so
what we can do is just in our browser
30

31
00:02:38,670 --> 00:02:44,340
just search for Cognito and there we go
we've got the Cognito identity pools
31

32
00:02:44,340 --> 00:02:51,870
that we need to access, we have the AWS
Cognito service being our user pools
32

33
00:02:51,870 --> 00:02:57,120
that we need to access as well and the
sink the Sync database as well the
33

34
00:02:57,120 --> 00:03:03,959
Cognito Sync key store we need to access that,
also we need to access Amazon s3 and so
34

35
00:03:03,959 --> 00:03:08,370
there are libraries there for Amazon s3
that we can add there too that is how
35

36
00:03:08,370 --> 00:03:13,909
easy it is to do it this way and very,
very quick and easy I love it
36

37
00:03:13,909 --> 00:03:18,690
so we've got here the build
configuration we've got identity user
37

38
00:03:18,690 --> 00:03:23,879
pools and sync and s3 there so we just
click on build after certain amount of
38

39
00:03:23,879 --> 00:03:29,579
time it'll build that for us and there
we can see we've got our AWS SDK which
39

40
00:03:29,579 --> 00:03:35,370
will be the latest stable version of the
SDK which is good and it will be
40

41
00:03:35,370 --> 00:03:43,049
optimized to include only Cognito and s3
and the basic AWS stuff such as config
41

42
00:03:43,049 --> 00:03:48,930
and all that sort of thing that we need
so that brings us to an end if you've
42

43
00:03:48,930 --> 00:03:54,629
enjoyed this make sure you go out there
and give it a good rating and it's a
43

44
00:03:54,629 --> 00:03:58,109
great it's been a great lab,
you've got a lot of stuff that's going
44

45
00:03:58,109 --> 00:04:02,310
on here and it's going to be really good
to do these sorts of very long and
45

46
00:04:02,310 --> 00:04:05,970
in-depth and intricate labs because it's
going to give you the confidence that
46

47
00:04:05,970 --> 00:04:10,590
you need to be able to use these
JavaScript SDKs and if you're going on
47

48
00:04:10,590 --> 00:04:14,909
to become an AWS certified developer
then you're going to have to have a lot
48

49
00:04:14,909 --> 00:04:20,070
of confidence in using the AWS
JavaScript SDK as well, so I've enjoyed
49

50
00:04:20,070 --> 00:04:25,610
it and I look forward to seeing you in
the next lecture
