1
00:00:02,220 --> 00:00:04,960
So finally, we got that token.

2
00:00:04,960 --> 00:00:07,840
Now, here, we can retrieve that token

3
00:00:08,880 --> 00:00:13,670
by accessing data.data,

4
00:00:15,060 --> 00:00:18,200
because it's the data fields that holds the token.

5
00:00:18,200 --> 00:00:20,170
And therefore, of course, if that's confusing,

6
00:00:20,170 --> 00:00:23,010
you can, of course, alter rename that argument to response,

7
00:00:23,010 --> 00:00:24,670
to access response data.

8
00:00:24,670 --> 00:00:27,470
But ultimately that will be our token.

9
00:00:27,470 --> 00:00:31,010
Now, we'll not need that token here for the moment,

10
00:00:31,010 --> 00:00:33,430
instead, I wanna use it to manually

11
00:00:33,430 --> 00:00:37,290
send a push notification to our real device.

12
00:00:37,290 --> 00:00:39,480
And testing push notifications

13
00:00:39,480 --> 00:00:43,880
is made easy with the Expo push notification tool.

14
00:00:43,880 --> 00:00:45,450
You can find it if you search for

15
00:00:45,450 --> 00:00:47,540
Expo push notifications.

16
00:00:47,540 --> 00:00:51,030
This is a tool which allows you to test push notifications

17
00:00:51,030 --> 00:00:53,880
you wanna send to your Expo projects.

18
00:00:53,880 --> 00:00:57,460
In reality, you would probably not use this tool,

19
00:00:57,460 --> 00:01:01,930
but you would use one of Expos server side STKs

20
00:01:01,930 --> 00:01:05,160
to trigger a push notification on the server,

21
00:01:05,160 --> 00:01:08,040
or you would send it from directly inside your app,

22
00:01:08,040 --> 00:01:10,200
As I will show you later in this module,

23
00:01:10,200 --> 00:01:12,040
depending on your use case.

24
00:01:12,040 --> 00:01:14,638
But for testing, this is a great tool.

25
00:01:14,638 --> 00:01:17,140
Now, as you see, it needs this push token

26
00:01:17,140 --> 00:01:19,380
in this format, we just saw it.

27
00:01:19,380 --> 00:01:22,480
So let's copy this push token,

28
00:01:22,480 --> 00:01:27,020
this full string here, and insert it here.

29
00:01:27,020 --> 00:01:30,519
That's the identifier of my device now.

30
00:01:30,519 --> 00:01:32,550
And then we can enter a title.

31
00:01:32,550 --> 00:01:37,550
This is a test. My first test message, as a body.

32
00:01:38,250 --> 00:01:40,820
We could add extra data if we wanted to.

33
00:01:40,820 --> 00:01:44,223
That should be in Jason format then though.

34
00:01:45,970 --> 00:01:49,890
And we can also add iOS and Android specific information,

35
00:01:49,890 --> 00:01:53,320
but for the moment, I'll just send this notification.

36
00:01:53,320 --> 00:01:55,170
And now I'm sending this notification

37
00:01:55,170 --> 00:01:57,000
whilst the app is in foreground.

38
00:01:57,000 --> 00:01:59,263
It would also work if it's in background.

39
00:02:00,310 --> 00:02:02,520
And you see here's the message delivered,

40
00:02:02,520 --> 00:02:03,440
and we can tap it.

41
00:02:03,440 --> 00:02:04,950
And if we do tap it,

42
00:02:04,950 --> 00:02:08,130
we run that same code I showed you before

43
00:02:08,130 --> 00:02:10,180
for the local notifications.

44
00:02:10,180 --> 00:02:12,140
So that code for handling incoming

45
00:02:12,140 --> 00:02:15,070
background or foreground notifications,

46
00:02:15,070 --> 00:02:16,842
that code still executes,

47
00:02:16,842 --> 00:02:20,320
and it still gives us access to the notification object

48
00:02:20,320 --> 00:02:22,610
and all the notification data.

49
00:02:22,610 --> 00:02:24,620
And that's in the end, all that's to it.

50
00:02:24,620 --> 00:02:26,918
This is how we send push notifications

51
00:02:26,918 --> 00:02:29,270
in an Expo application.

52
00:02:29,270 --> 00:02:32,040
As you can see, it's really not that difficult,

53
00:02:32,040 --> 00:02:35,350
thanks to Expo's own push server,

54
00:02:35,350 --> 00:02:38,330
which in the end wraps those official servers,

55
00:02:38,330 --> 00:02:41,150
and which has done all the nitty gritty details

56
00:02:41,150 --> 00:02:45,650
of registering itself with those official service for us.

57
00:02:45,650 --> 00:02:49,080
Instead, we just use these convenient methods I showed you,

58
00:02:49,080 --> 00:02:52,090
and we can deliver push notifications.

59
00:02:52,090 --> 00:02:55,620
Now, let me show you how we can trigger push notifications

60
00:02:55,620 --> 00:02:57,603
from inside the app.
