1
00:00:00,800 --> 00:00:05,370
In the last section we were able to test out the first step of our processing pipeline.

2
00:00:05,370 --> 00:00:07,280
I clicked on one of the links inside the email.

3
00:00:07,320 --> 00:00:11,660
We waited a little bit and now I see a console log of this object right here.

4
00:00:11,670 --> 00:00:18,270
Notice how the object has a survey ID with the idea the survey that we have sent out and the choice

5
00:00:18,510 --> 00:00:20,940
which indicates the button that the user clicked.

6
00:00:20,970 --> 00:00:22,980
In this case yes.

7
00:00:23,430 --> 00:00:27,770
So going back over to our code right now here is the value that we had Konst logged out.

8
00:00:27,780 --> 00:00:30,900
We had counsel logged out peanut test pathname.

9
00:00:30,900 --> 00:00:37,710
So this parse object right here will return an object that contains every sort of wild card that was

10
00:00:37,710 --> 00:00:40,470
matched up from the given you are out or route.

11
00:00:40,470 --> 00:00:43,290
I should say in this case pathname.

12
00:00:43,410 --> 00:00:52,190
Now if the parse object right here is not able to extract both a survey ID and a choice then peacoat

13
00:00:52,290 --> 00:00:55,520
test pathname will return NULL instead.

14
00:00:55,560 --> 00:01:01,170
And so that's what's going to help us make sure that we somehow discard records that do not have a survey

15
00:01:01,170 --> 00:01:07,870
ID and a choice let's adjust our code a little bit and figure out exactly how we'll do that.

16
00:01:07,950 --> 00:01:14,610
So I'm going to delete the consulate log statement right now and now I'm going to rewrite that picquet

17
00:01:14,670 --> 00:01:22,720
test pathname which is returning that object with the survey ID and the choice.

18
00:01:22,740 --> 00:01:27,870
I'm now going to assign that object to a variable called Match like so.

19
00:01:28,120 --> 00:01:33,530
So now at this point remember match will either be an object or it will be null.

20
00:01:33,660 --> 00:01:38,800
If a test was not able to extract both the survey ID and the choice.

21
00:01:39,180 --> 00:01:46,620
So now we can look at the match variable and say if a match was found just return that match object

22
00:01:47,100 --> 00:01:48,470
like so.

23
00:01:49,050 --> 00:01:53,910
Now before we just stop right here and say this is enough remember that we are currently processing

24
00:01:53,910 --> 00:01:58,410
the list of all the different events and the three different pieces of data that we really care about.

25
00:01:58,410 --> 00:02:05,400
Here are the survey I.D. the choice and the users e-mail and the users e-mail is contained inside of

26
00:02:05,400 --> 00:02:06,990
that event object.

27
00:02:07,080 --> 00:02:12,240
And so to make sure that we kind of return or walk away from this with all the exact pieces of data

28
00:02:12,240 --> 00:02:17,130
that we care about I want to make sure that rather than just returning the survey ID and the choice

29
00:02:17,400 --> 00:02:22,740
we instead return an object that has the survey ID the choice and the users email.

30
00:02:22,950 --> 00:02:27,030
So we're going to modify this return statement a little bit to return an object that we're going to

31
00:02:27,030 --> 00:02:28,170
create.

32
00:02:28,230 --> 00:02:34,680
So we'll say returning an object that has the email from the event object or the event argument.

33
00:02:34,680 --> 00:02:41,100
So the email is going to be taken from event dot email then we're going to make sure that we take the

34
00:02:41,100 --> 00:02:44,580
survey I.D. and the choice from the match object.

35
00:02:44,610 --> 00:02:53,340
So let's say survey I.D. will be matched on survey I.D. and we make sure that the choice is coming from

36
00:02:53,490 --> 00:02:57,650
match dot choice like so.

37
00:02:58,060 --> 00:03:02,600
Now I'm seeing a lot of opportunities here for a little bit of E-6 refactoring.

38
00:03:02,650 --> 00:03:03,660
So let's give that a shot.

39
00:03:03,670 --> 00:03:07,960
Let's do a little bit of refactoring to kind of tighten up all the code in here by using a little bit

40
00:03:07,990 --> 00:03:09,640
of destructuring.

41
00:03:09,640 --> 00:03:15,190
So I think that the first thing we can do is recognize that the event object we really only care about

42
00:03:15,190 --> 00:03:18,130
the URL and the email properties.

43
00:03:18,400 --> 00:03:25,930
So on the argument to the map function instead of the event we'll say parentheses curly braces and give

44
00:03:25,930 --> 00:03:30,100
me just the email and the URL properties out of here.

45
00:03:30,100 --> 00:03:35,110
Now when we pass off the event you are able to you all helper right here.

46
00:03:35,290 --> 00:03:42,160
We can condense it to be just you l like so inside of the object that we're returning rather than saying

47
00:03:42,190 --> 00:03:46,730
event or email we can condense it to be just email like so.

48
00:03:47,050 --> 00:03:51,240
Now you'll notice that the email property and value right here are identical.

49
00:03:51,310 --> 00:03:53,690
So we can condense it down to just e-mail.

50
00:03:54,070 --> 00:03:54,980
And that's not all.

51
00:03:54,980 --> 00:03:56,860
And we can go even further here.

52
00:03:56,890 --> 00:04:00,590
Notice that out of the match object right here.

53
00:04:00,610 --> 00:04:01,990
Oh I know it actually is.

54
00:04:02,020 --> 00:04:03,340
Excuse me this is actually really important.

55
00:04:03,340 --> 00:04:08,650
We actually can't do any destructuring of this thing right here because P-ROC test is either going to

56
00:04:08,650 --> 00:04:15,620
return an object with Servi ID and choice but if it is not able to make the match it will return.

57
00:04:15,970 --> 00:04:19,450
So we actually cannot do any destructuring off pee test right here.

58
00:04:19,450 --> 00:04:25,330
We cannot do something like Oh give me only the survey ID and the choice because if P-ROC test returns

59
00:04:25,360 --> 00:04:30,400
no then this structure in logic right here will throw an error because we're essentially trying to re

60
00:04:30,400 --> 00:04:33,490
properties off of Knol and that throws an error.

61
00:04:33,490 --> 00:04:38,770
So I think that the best we can do is essentially this right here OK.

62
00:04:39,170 --> 00:04:41,500
So I'm thinking this is looking pretty good at this step.

63
00:04:41,990 --> 00:04:48,690
I think that we can now after this entire map statement right here let's add in one last little console

64
00:04:48,690 --> 00:04:54,250
log just to make sure that we are returning an object with only the properties that we really care about.

65
00:04:54,260 --> 00:04:58,430
So a console log events like so.

66
00:04:58,430 --> 00:05:03,380
And now let's click on a link inside of an email and get the thing to log out the list that we are now

67
00:05:03,410 --> 00:05:05,990
generating from the map function.

68
00:05:06,050 --> 00:05:09,290
So go back over to my test email right here.

69
00:05:09,290 --> 00:05:11,760
I'm going to click on the Yes button.

70
00:05:12,070 --> 00:05:17,650
It does its thing and they will flip over the terminal and just wait to get some response here.

71
00:05:17,690 --> 00:05:20,720
Now of course again we have to wait for something actually come through.

72
00:05:20,720 --> 00:05:22,080
So let's take a quick break.

73
00:05:22,100 --> 00:05:27,530
We come back we'll hope that we see the console log of whatever we are returning in total from that

74
00:05:27,530 --> 00:05:28,460
map statement.

75
00:05:28,460 --> 00:05:29,880
So I'll see you in just a minute.
