1
00:00:00,950 --> 00:00:05,390
In the last section we were able to determine our users current location just to show you something

2
00:00:05,390 --> 00:00:06,770
interesting really quick.

3
00:00:06,830 --> 00:00:12,140
I want you to recall that as the second argument to that get current position function we put an air

4
00:00:12,140 --> 00:00:13,260
callback.

5
00:00:13,280 --> 00:00:18,110
So one thing that we really want to test as we develop the supplication is to make sure that we have

6
00:00:18,110 --> 00:00:20,710
a good understanding of what happens in the app.

7
00:00:20,750 --> 00:00:27,230
If for some reason the geolocation call fails Now one reason that might cause that call to fail is if

8
00:00:27,230 --> 00:00:32,300
the user declines or does not allow their position to be shared with our app.

9
00:00:32,360 --> 00:00:37,940
I don't know about you but any time that any single web site in the world asked me for my location I

10
00:00:38,000 --> 00:00:39,270
always decline it.

11
00:00:39,270 --> 00:00:43,220
I was denied entirely unless I definitely want to have it share.

12
00:00:43,240 --> 00:00:46,020
But vast majority time I always deny it.

13
00:00:46,130 --> 00:00:52,940
So we're going to make sure that we develop our application to work even if a user declines that request

14
00:00:53,000 --> 00:00:54,950
to share their location.

15
00:00:54,960 --> 00:00:59,460
Now in order to test that flow to make sure that you and I understand what happens inside of our application

16
00:00:59,460 --> 00:01:05,040
when it gets denied we need to to kind of reset our permissions very easily to make sure that we get

17
00:01:05,040 --> 00:01:10,810
that allow or deny a pop up to appear on our screen again because as you might notice every time you

18
00:01:10,810 --> 00:01:15,330
refreshed this page after allowing At one time you're never going to get asked again.

19
00:01:15,660 --> 00:01:20,620
So in order to get asked again all you got to do is find this little guy next to our address.

20
00:01:20,730 --> 00:01:23,840
You'll notice that we get this dropdown and it says location.

21
00:01:23,910 --> 00:01:25,860
We are always allowing.

22
00:01:25,980 --> 00:01:31,020
So in order to test our application and make sure that it still works correctly even if we deny the

23
00:01:31,020 --> 00:01:38,910
location request I can reset this to ask default like so and then I can refresh the page and then I'm

24
00:01:38,910 --> 00:01:45,180
back to square one where I get asked if I'm going to allow localhost thousand to know my location.

25
00:01:45,180 --> 00:01:51,350
So this time around I go ahead and hit block and then you'll see that we get this position air object

26
00:01:51,740 --> 00:01:56,590
that gives us some reason to tell us exactly why the geo location failed.

27
00:01:56,780 --> 00:02:01,190
It's like I said we're going to be using this a little bit as we go on throughout this application to

28
00:02:01,190 --> 00:02:05,580
make sure that the app still has a reasonable degree of functionality.

29
00:02:05,660 --> 00:02:11,220
If for some reason we are not able to get the user's location Now one thing to keep in mind is that

30
00:02:11,250 --> 00:02:14,620
if I now refresh the page again it's still going to be blocked.

31
00:02:14,790 --> 00:02:20,340
So in practice you and I as we go to this application we're going to be using this dropdown many many

32
00:02:20,340 --> 00:02:23,310
times to test out the entire flow of our application.

33
00:02:24,420 --> 00:02:24,740
OK.

34
00:02:24,800 --> 00:02:28,560
So now that we have a really good idea of how this geolocation stuff works.

35
00:02:28,610 --> 00:02:32,540
One more quick pause then we'll come back and write some more code into our app component.
