1
00:00:02,230 --> 00:00:03,470
So now that we added

2
00:00:03,510 --> 00:00:04,290
sign up,

3
00:00:04,290 --> 00:00:09,440
let's also add log in. For this, in the auth handler in the app.js file,

4
00:00:09,450 --> 00:00:15,330
we need to find an alternative to signing a user up as we're currently doing it and previously, I had an if check

5
00:00:15,330 --> 00:00:16,050
here.

6
00:00:16,050 --> 00:00:18,920
So let me reintroduce that if check here

7
00:00:21,290 --> 00:00:26,170
and I'll again work with that request variable which I'll also re-add here

8
00:00:26,540 --> 00:00:34,090
and now request either holds my email pass client register with e-mail logic,

9
00:00:34,090 --> 00:00:38,300
that happens here when I want to sign up,

10
00:00:38,330 --> 00:00:45,480
so then request is equal to the result of that and I can then use request down there

11
00:00:46,630 --> 00:00:48,820
or I do log in

12
00:00:48,820 --> 00:00:53,840
and now how do I log in with stitch? For that I need to add an import

13
00:00:53,840 --> 00:00:57,680
first of all, I need to import the user password credential,

14
00:00:57,740 --> 00:01:00,480
you remember? Previously we used the anonymous credential,

15
00:01:00,500 --> 00:01:03,180
now we simply use the user password credential.

16
00:01:03,320 --> 00:01:09,060
So I am importing that and I'll now create a new credential here,

17
00:01:10,010 --> 00:01:10,690
credential,

18
00:01:14,710 --> 00:01:19,480
a new user password credential with the two pieces of information I have,

19
00:01:19,480 --> 00:01:27,680
so with the e-mail and the password. So I'll again pass auth data e-mail here and auth data password as a

20
00:01:27,670 --> 00:01:29,050
a second argument.

21
00:01:29,050 --> 00:01:35,700
So now with that credential, we can log in just as we did it before with the anonymous credential.

22
00:01:35,720 --> 00:01:37,800
So here to login,

23
00:01:38,060 --> 00:01:41,700
I'll actually use my general stitch client with this client,

24
00:01:41,900 --> 00:01:50,030
then auth and there, I can call log in with credential and pass my credential which I created here as

25
00:01:50,030 --> 00:01:52,120
an argument.

26
00:01:52,120 --> 00:01:57,820
Now this will give me a promise and hence I can safely store this in request and then here let's see

27
00:01:57,820 --> 00:02:00,160
what we have as a result now,

28
00:02:00,550 --> 00:02:07,480
so here, so in here let me console log result.

29
00:02:07,550 --> 00:02:10,260
So now we should have a log inflow too,

30
00:02:10,580 --> 00:02:12,200
so let's go back to our application,

31
00:02:12,230 --> 00:02:18,200
make sure you're in log in mode and then try the credentials you used for signing up with your e-mail

32
00:02:18,290 --> 00:02:22,670
and of course, the correct password.

33
00:02:22,780 --> 00:02:25,850
Now I get a reply here and that reply looks positive,

34
00:02:25,860 --> 00:02:27,100
it's not an error

35
00:02:27,390 --> 00:02:33,360
and this simply confirms to me that I am logged in and the whole session of the user to the tokens to

36
00:02:33,360 --> 00:02:36,390
be precise are managed by stitch behind the scenes.

37
00:02:36,390 --> 00:02:41,640
You can by the way see them if you go to the application tab in your chrome browser dev tools and you

38
00:02:41,640 --> 00:02:43,620
then check out your local storage,

39
00:02:43,770 --> 00:02:50,550
you should see that stitch client thing here which in the end stores information about your user,

40
00:02:50,760 --> 00:02:53,520
where you see for example the token that is managed for you.

41
00:02:53,670 --> 00:02:56,950
So that is what stitch does for you, you don't need to worry about that,

42
00:02:57,060 --> 00:02:59,720
you now have a way of logging in.

43
00:02:59,730 --> 00:03:06,540
So what you know here by this point is that if result is set because it was undefined for signing up

44
00:03:06,540 --> 00:03:07,270
if you remember,

45
00:03:07,380 --> 00:03:11,460
so if we have a value for result, then we are logged in

46
00:03:11,490 --> 00:03:17,890
and in this case, I want to also change my authentication status,

47
00:03:17,930 --> 00:03:24,250
so then I want to call this set state is auth true so that I also reflect this in my user interface.

48
00:03:24,310 --> 00:03:28,780
So now again if I do enter my valid credentials here,

49
00:03:32,070 --> 00:03:33,150
I am logged in

50
00:03:33,150 --> 00:03:34,910
and now I load my products.

51
00:03:34,920 --> 00:03:40,500
Now let's also adjust our rules such that only logged in users can interact with the products.
