1
00:00:00,940 --> 00:00:01,320
All right.

2
00:00:01,330 --> 00:00:04,600
Enough videos about the design or architecture of our application.

3
00:00:04,600 --> 00:00:06,480
Time to actually start writing some code.

4
00:00:06,520 --> 00:00:09,650
So in this video we're going to start working on our off service.

5
00:00:09,700 --> 00:00:14,470
This all service is going to be in charge of handling sign up signing in and so on.

6
00:00:14,470 --> 00:00:18,390
In total are off service is going to have four different routes assigned to it.

7
00:00:18,430 --> 00:00:24,310
So while the ability to sign up with the post request sign in with the Post sign out with the Post and

8
00:00:24,310 --> 00:00:27,380
also get information about the currently signed end user.

9
00:00:27,580 --> 00:00:29,670
So let's go back over to our terminal right away.

10
00:00:29,740 --> 00:00:34,750
We're going to start to generate some different files we're gonna do some NPM installation get some

11
00:00:34,750 --> 00:00:35,290
modules.

12
00:00:35,290 --> 00:00:41,760
All that kind of stuff for our off service to back at my terminal.

13
00:00:41,830 --> 00:00:44,350
I'm still inside my blog project directory.

14
00:00:44,350 --> 00:00:49,560
I'm gonna change out of that folder so I'm now back inside of a workspace directory and inside if you're

15
00:00:49,630 --> 00:00:53,610
going to generate a new overall folder for all of our different services.

16
00:00:53,650 --> 00:00:55,560
I'm going to call this ticketing.

17
00:00:55,730 --> 00:01:01,540
That is the name of our project ticketing then inside of ticketing.

18
00:01:01,560 --> 00:01:09,910
I'll create a new directory of off and change into it and then inside of this auth directory I'll run

19
00:01:10,030 --> 00:01:11,040
NPM in it.

20
00:01:11,120 --> 00:01:18,450
Dash Y there's our package dot Chase on file then inside of here we're going to first install a couple

21
00:01:18,450 --> 00:01:21,680
of different dependencies.

22
00:01:21,740 --> 00:01:26,910
I'm going to install typescript because remember we are gonna use typescript on this project.

23
00:01:26,910 --> 00:01:32,400
I'm gonna get Tess node Dev which is a tool that we're going to use to actually execute our project

24
00:01:32,400 --> 00:01:35,290
in a development environment.

25
00:01:35,400 --> 00:01:43,800
I'm going to get express I'll get at types slash Express and we'll just do that installation for right

26
00:01:43,800 --> 00:01:44,130
now.

27
00:01:44,130 --> 00:01:48,300
We will come back very shortly and add in many other dependencies into this project.

28
00:01:48,300 --> 00:01:54,050
But that's good enough to get started with so while that is running and then going to open up my code

29
00:01:54,050 --> 00:01:56,740
editor inside of our overall project directory.

30
00:01:56,750 --> 00:02:02,500
So the ticketing folder though looks like that's all done I'll change back out to ticketing and open

31
00:02:02,500 --> 00:02:04,320
up my code editor inside there.

32
00:02:06,680 --> 00:02:06,910
All right.

33
00:02:06,920 --> 00:02:09,420
So now we should see that auth project director right there.

34
00:02:09,470 --> 00:02:14,460
There's our package dot Chase on file then back at my terminal.

35
00:02:14,480 --> 00:02:20,380
I'm gonna change into that auth directory one more time and I'm going to generate a T S config file

36
00:02:20,380 --> 00:02:25,990
inside of here with TSC dash dash in it.

37
00:02:26,080 --> 00:02:27,780
So that's enough to get started with.

38
00:02:28,040 --> 00:02:34,580
I'm gonna go back over to my editor and I'll start writing out some code inside my auth directory.

39
00:02:34,580 --> 00:02:37,970
I'm gonna make a new folder called S.R. c.

40
00:02:38,090 --> 00:02:41,690
We're gonna start placing all of our code inside this our C directory.

41
00:02:41,690 --> 00:02:48,450
I'm going to first begin by creating a app Dot T S or C me index Dot T S to get started with file inside

42
00:02:48,450 --> 00:02:49,960
this index not t s file.

43
00:02:50,000 --> 00:02:55,230
Then throw in some basic syntax and basic imports all that kind of stuff to get an express application

44
00:02:55,290 --> 00:02:56,670
up and running.

45
00:02:56,670 --> 00:03:00,410
So I will do an import Express from Express

46
00:03:03,110 --> 00:03:11,130
or then get my Jason from body dash parser I'm going to create a new app

47
00:03:14,640 --> 00:03:17,080
then I will associate the Jason middleware with it.

48
00:03:17,100 --> 00:03:21,470
So app use Jason.

49
00:03:21,720 --> 00:03:24,790
I'm not going to worry about setting up any root handlers just yet.

50
00:03:24,870 --> 00:03:27,930
And so finally I'll do an app to listen in this time around.

51
00:03:27,930 --> 00:03:30,570
We're gonna do a listen on port three thousand member.

52
00:03:30,570 --> 00:03:34,520
The port doesn't really make a difference once we start making use of Cuban eddies because we're gonna

53
00:03:34,530 --> 00:03:36,420
start to create all these different services.

54
00:03:36,450 --> 00:03:41,930
A Cuban navy service that is that's going to govern access to this off thing that we're putting together.

55
00:03:42,030 --> 00:03:47,080
So right now we'll just use a service sub three thousand because again doesn't really make a big difference.

56
00:03:47,830 --> 00:03:54,050
And then I would will put in a call back with the console log of listening on port three thousand

57
00:03:57,040 --> 00:03:59,390
let's now go over to our package shot Jason File.

58
00:03:59,410 --> 00:04:02,080
We're going to set up a start script inside there.

59
00:04:02,210 --> 00:04:03,310
So inside a package stop.

60
00:04:03,310 --> 00:04:10,520
Jason I'm going to remove the test script I can replace it would start and the command that we're going

61
00:04:10,520 --> 00:04:18,100
to run to start this thing up is test dash node dash dev and we want to run source slash index start

62
00:04:18,130 --> 00:04:19,250
to yes like so

63
00:04:22,650 --> 00:04:27,030
we are going to eventually run this thing inside of Cuban net is about right now let's change into this

64
00:04:27,060 --> 00:04:28,450
auth directory at our terminal.

65
00:04:28,590 --> 00:04:34,120
It just makes sure that we could run NPM start and have our application startup look back at my terminal

66
00:04:35,050 --> 00:04:41,450
I'm inside my auth directory still so I'll do an NPM start and there we go.

67
00:04:41,450 --> 00:04:43,350
Looks like we are all set.

68
00:04:43,570 --> 00:04:43,820
OK.

69
00:04:43,850 --> 00:04:46,120
So just a little bit of boilerplate to get started.

70
00:04:46,160 --> 00:04:50,000
Let's take a pause right here and discuss a couple of different things around this OTT service in just

71
00:04:50,000 --> 00:04:50,330
a moment.
