1
00:00:01,030 --> 00:00:05,210
In this video we're going to do a little bit of basic setup of the expiration service.

2
00:00:05,260 --> 00:00:09,790
They're going to create a new sub project directory install some dependencies all that kind of low level

3
00:00:09,790 --> 00:00:10,340
stuff.

4
00:00:10,390 --> 00:00:13,530
Let's get to it right away back inside of my editor.

5
00:00:13,540 --> 00:00:17,740
I'm going to create a new directory called expiration now.

6
00:00:17,750 --> 00:00:23,930
I would love to add in a ton of stuff for the base project from scratch but just to save time in the

7
00:00:23,930 --> 00:00:28,250
context of this course we're going to instead copy over a couple of different files from our ticket

8
00:00:28,250 --> 00:00:32,650
service just to save some time inside of my tickets directory.

9
00:00:32,680 --> 00:00:40,090
I'm going to do a multi select of Docker ignore the docker file package Jason and the T S config Jason

10
00:00:40,090 --> 00:00:48,000
File as well once I've got all four files I'm then going to copy all them and then paste them into the

11
00:00:48,000 --> 00:00:56,110
expiration directory that we just created inside of expiration and then also going to create a s our

12
00:00:56,110 --> 00:01:03,440
C directory and we'll copy over one or two things from the SLC folder inside of tickets inside of the

13
00:01:03,500 --> 00:01:04,280
ticket service.

14
00:01:04,280 --> 00:01:10,860
I'll find the s RC directory and once again we will do a multi select this time of Nat's wrapper index

15
00:01:10,870 --> 00:01:13,640
T S and the MOX directory.

16
00:01:13,640 --> 00:01:20,780
So three things and total I'm going to copy those three things then paste them into the expiration services

17
00:01:20,860 --> 00:01:27,750
S.R. C directory that we just created so at this point you should have an identical directory structure

18
00:01:27,810 --> 00:01:32,040
please double check it just make sure you've got everything identical to what I show Inside the expiration

19
00:01:32,040 --> 00:01:34,170
service.

20
00:01:34,370 --> 00:01:38,420
Once you've got that all setup we're then going to go through a couple of these different files and

21
00:01:38,420 --> 00:01:43,280
just clean them up get them ready for the expiration service instead of the very particular setup they

22
00:01:43,280 --> 00:01:44,770
have for the ticket service.

23
00:01:45,530 --> 00:01:48,270
Well first begin with the package JS on file.

24
00:01:48,350 --> 00:01:52,910
We're gonna go through here and remove a couple of different dependencies and add one or two as well.

25
00:01:55,200 --> 00:02:00,570
Inside of the package it's on file inside the expiration service will update the name right here to

26
00:02:00,600 --> 00:02:05,740
expiration not actually required but might as well do it while we're here.

27
00:02:05,770 --> 00:02:08,900
Well then go and take a look at our dependency list.

28
00:02:09,030 --> 00:02:14,490
We've got a lot of dependencies inside of your related to handling network requests or HDTV requests

29
00:02:14,850 --> 00:02:19,050
specifically everything around express tokens and sessions.

30
00:02:19,050 --> 00:02:20,370
Cookie is all that stuff.

31
00:02:20,370 --> 00:02:23,380
We do not need any of that stuff with the expiration service.

32
00:02:23,760 --> 00:02:26,580
So we're going to remove a lot of these different dependencies.

33
00:02:26,580 --> 00:02:33,270
I'm going to highlight everything from types cookies session right here all the way down to Mongoose

34
00:02:33,360 --> 00:02:39,050
update if current and I'm going to delete all those dependencies.

35
00:02:39,140 --> 00:02:44,480
Now we are left with just for just the four you see right here.

36
00:02:44,600 --> 00:02:52,350
Next up inside the deb dependency section I'm going to delete hypes Super Test I will delete Mongo DV

37
00:02:52,410 --> 00:02:56,190
memory server and I will delete super test as well.

38
00:02:56,930 --> 00:02:58,670
There left with just these three.

39
00:02:58,670 --> 00:03:02,130
Nothing else okay.

40
00:03:02,160 --> 00:03:04,840
Looks good I'm going to save this file.

41
00:03:04,870 --> 00:03:09,100
Well then go back over to our terminal and we're going to install these dependencies and add in one

42
00:03:09,100 --> 00:03:10,000
or two others.

43
00:03:11,360 --> 00:03:12,570
So back at my terminal.

44
00:03:12,780 --> 00:03:15,500
I've already changed in to my new expiration directory.

45
00:03:15,570 --> 00:03:18,100
So make sure you change into expiration as well.

46
00:03:18,920 --> 00:03:23,380
Then once inside there we're going to install two packages.

47
00:03:23,780 --> 00:03:24,800
One is bold.

48
00:03:24,800 --> 00:03:29,730
So that is the job processing manager that we're going to use.

49
00:03:29,770 --> 00:03:33,040
We're also going to get the type definition file rebel as well.

50
00:03:33,070 --> 00:03:37,100
So that's at types slash all.

51
00:03:37,210 --> 00:03:43,050
I'm gonna run that and when we run npm install for these two packages those are the only packages that

52
00:03:43,050 --> 00:03:44,020
get installed.

53
00:03:44,040 --> 00:03:48,570
We then have to run a normal npm install to make sure that everything else we list inside of our package

54
00:03:48,600 --> 00:03:51,370
Jason File gets added in as well.

55
00:03:51,420 --> 00:03:58,120
So after that first command completes I'll then do a normal npm install all right.

56
00:03:58,120 --> 00:04:00,550
That's going to take a month or two solid just like it does thing.

57
00:04:00,550 --> 00:04:07,370
And I'm going to put back over where we will keep doing just a little bit of additional setup.

58
00:04:07,460 --> 00:04:11,420
So next year we're gonna do is take a look at our index not TSA file and we're gonna clean up a lot

59
00:04:11,420 --> 00:04:14,690
of stuff inside of here that is not going to be used inside of our expiration service.

60
00:04:15,930 --> 00:04:17,190
So inside of index yes.

61
00:04:17,220 --> 00:04:19,260
Again inside the expiration service.

62
00:04:19,530 --> 00:04:21,730
I'm going to delete the import for mongoose.

63
00:04:21,810 --> 00:04:32,310
I'll delete the import for app and I'll delete the two imports for these two listeners.

64
00:04:32,370 --> 00:04:37,490
Well then start to clean up these two first environment variable checks so we don't need a Jason with

65
00:04:37,490 --> 00:04:39,540
token key or a mango you or I.

66
00:04:39,890 --> 00:04:44,920
But we will leave around the next three then going down a little bit.

67
00:04:45,080 --> 00:04:47,550
We still need all this stuff around that's wrapper.

68
00:04:47,660 --> 00:04:53,040
The Nats wrapper client close and the process stuff right there as well.

69
00:04:54,260 --> 00:05:02,000
But then after that we're going to delete the two listeners we'll delete the Mongoose connect statement

70
00:05:02,150 --> 00:05:08,180
and the console log that says connected to mongo DB and then finally it will we will delete the app.

71
00:05:08,180 --> 00:05:16,230
Listen call at the very bottom and that's it.

72
00:05:16,420 --> 00:05:21,590
I'll save this file and close it to other files I want to check really quickly.

73
00:05:21,650 --> 00:05:23,680
So if we take a look at Nats wrapper.

74
00:05:23,680 --> 00:05:26,470
All right we just have some stuff inside of here around that mark.

75
00:05:26,560 --> 00:05:32,420
Not that we really need to fix up right now and then inside of the Nats wrapper TSA file we do have

76
00:05:32,420 --> 00:05:35,270
an import for node not streaming that's fine.

77
00:05:35,270 --> 00:05:39,910
We're seeing a couple of errors here around typescript you may or may not see these errors at all.

78
00:05:40,010 --> 00:05:41,930
If you do see these errors like I do.

79
00:05:41,930 --> 00:05:50,400
The way to fix them is once again command ship p on your keyboard and search for reload window alternately

80
00:05:50,430 --> 00:05:56,500
you could just restart your ED All right that looks a lot better for me.

81
00:05:56,600 --> 00:05:58,760
OK so that's pretty much it with some initial setup.

82
00:05:58,830 --> 00:06:00,670
We're going to take a pause right here when we come back.

83
00:06:00,670 --> 00:06:05,890
Next video we're going to build an initial Docker image but this expiration service will then create

84
00:06:05,890 --> 00:06:10,510
a couple of different Cuban settings config files to create a new deployment for our expiration service

85
00:06:10,720 --> 00:06:12,850
and also create that reddest instance as well.
