1
00:00:00,240 --> 00:00:04,640
In the last video you created accounts with both get hub and Heroku.

2
00:00:04,740 --> 00:00:10,860
Now in the end of the day both of those tools they need access to our project code Heroku is going to

3
00:00:10,860 --> 00:00:16,950
need access to the project code so it can actually deploy our node applications and get how it needs

4
00:00:16,950 --> 00:00:23,130
access to the project code so it can show it on the project home page allowing us to collaborate with

5
00:00:23,160 --> 00:00:28,730
others track code changes over time or manage issues in our application.

6
00:00:28,740 --> 00:00:34,490
Either way we need a reliable way to get our code to both of those services.

7
00:00:34,500 --> 00:00:39,840
Now the answer is not to just zip up the folder and send it off to those services.

8
00:00:39,840 --> 00:00:46,470
The answer is to use version control with get in this video we're going to talk about what version control

9
00:00:46,470 --> 00:00:53,460
is and what get is will get get installed and that's going to allow us to actually use it in the next

10
00:00:53,460 --> 00:00:54,870
video to get started.

11
00:00:54,930 --> 00:01:01,740
Let's talk about what exactly version control is version control allows you to manage the versions of

12
00:01:01,740 --> 00:01:03,680
your application over time.

13
00:01:03,780 --> 00:01:10,680
So imagine the web server project as we add new features or change code with version control we can

14
00:01:10,680 --> 00:01:17,910
track those changes we can create what are essentially save points along the way for the various versions

15
00:01:17,970 --> 00:01:19,390
of our application.

16
00:01:19,440 --> 00:01:21,150
Now why is that useful.

17
00:01:21,150 --> 00:01:26,860
Well imagine you had an application and you had a thousand users who were paying you for that app.

18
00:01:26,940 --> 00:01:31,950
You want to add a new feature to give your users something new and exciting so you make some changes

19
00:01:31,950 --> 00:01:34,220
to your project and you deploy it.

20
00:01:34,230 --> 00:01:37,710
Now let's say that you discover that something's wrong with that new feature.

21
00:01:37,710 --> 00:01:38,550
There's a bug.

22
00:01:38,580 --> 00:01:39,880
So what do you want to do.

23
00:01:39,930 --> 00:01:45,120
You want to revert to the previous working state then you want to spend a little more time working on

24
00:01:45,120 --> 00:01:50,370
that new feature and when it's ready and the bug is fixed you'll deploy it back to your users.

25
00:01:50,370 --> 00:01:56,460
That's a very simple workflow but without version control you're not going to have an easy way to revert

26
00:01:56,460 --> 00:01:59,880
back to a previous working state of your application.

27
00:01:59,880 --> 00:02:05,730
The only version of the project you have is the broken one you're locally saved files unless you have

28
00:02:05,730 --> 00:02:09,330
a picture perfect memory and a lot of spare time on your hands.

29
00:02:09,390 --> 00:02:15,240
You're not going to be able to revert to the application back to its previously working state with version

30
00:02:15,240 --> 00:02:15,950
control.

31
00:02:16,020 --> 00:02:18,180
You could do that in about a second.

32
00:02:18,360 --> 00:02:21,130
So without version control you are living on the edge.

33
00:02:21,150 --> 00:02:25,350
If anything goes wrong it's going to be a big problem.

34
00:02:25,410 --> 00:02:30,160
You're going to have to manually work with all of these files to figure out what went wrong or you're

35
00:02:30,160 --> 00:02:34,270
going to have to rewrite them if they get lost with version control.

36
00:02:34,290 --> 00:02:35,300
You're in the clear.

37
00:02:35,340 --> 00:02:40,890
You can experiment and try different ways to approach problems if solution one doesn't work.

38
00:02:40,890 --> 00:02:46,600
You can revert those changes in a second and you can try to approach the problem from a different angle.

39
00:02:46,620 --> 00:02:52,500
It gives you flexibility and confidence knowing you can experiment with your code but always get back

40
00:02:52,500 --> 00:02:54,720
to that working state you had before.

41
00:02:54,720 --> 00:03:00,630
Without wasting your time and energy you should be using version control for every personal and professional

42
00:03:00,630 --> 00:03:02,120
project you're working on.

43
00:03:02,370 --> 00:03:08,430
If you're willing to spend time writing code it's best to spend an extra 10 seconds to integrate version

44
00:03:08,430 --> 00:03:14,700
control allowing you to track those version changes over time and manage your application code with

45
00:03:14,850 --> 00:03:15,740
ease.

46
00:03:15,750 --> 00:03:19,610
Now in this course we'll be using the get version control system.

47
00:03:19,620 --> 00:03:25,770
There are other version control tools out there but it is by far the most popular and the most widely

48
00:03:25,770 --> 00:03:27,670
used and for a good reason.

49
00:03:27,750 --> 00:03:33,330
It's super fast and easy to work with and you can use get regardless of the programming language you're

50
00:03:33,330 --> 00:03:34,310
working with.

51
00:03:34,410 --> 00:03:41,790
You could use get with Java with an iPhone application or in our case with node j s we can install and

52
00:03:41,790 --> 00:03:44,640
learn more about get over in the browser.

53
00:03:44,670 --> 00:03:52,420
I'm going to change the documentation you are all over to get hyphen s CRM dot com here.

54
00:03:52,440 --> 00:03:57,270
There are a ton of great resources that teach you how to use get that will cover the basics and the

55
00:03:57,270 --> 00:03:58,060
class.

56
00:03:58,080 --> 00:04:04,980
And here we can also install these get tools allowing us to integrate version control into our programming

57
00:04:04,980 --> 00:04:05,830
projects.

58
00:04:05,850 --> 00:04:09,380
Right here you should see the installer for your operating system.

59
00:04:09,380 --> 00:04:12,630
Here I have the installer for Mac and down below.

60
00:04:12,630 --> 00:04:15,080
I just want to point you to one more resource.

61
00:04:15,120 --> 00:04:20,580
There is a book called Pro get it's a free book and it's available to read right here on the get to

62
00:04:20,580 --> 00:04:21,510
Web site.

63
00:04:21,510 --> 00:04:26,520
I definitely recommend checking it out as you continue on with your development career.

64
00:04:26,520 --> 00:04:32,520
If you move into any real development position they're gonna be using get most likely and knowing how

65
00:04:32,650 --> 00:04:36,080
it works is going to allow you to get up and running quickly.

66
00:04:36,090 --> 00:04:41,340
For now though let's go ahead and just grab the installer so we can use get in our project.

67
00:04:41,340 --> 00:04:46,860
This is going to download what you need in order to get the tools set up and once again this is going

68
00:04:46,860 --> 00:04:50,220
to give us access to something new from the terminal.

69
00:04:50,220 --> 00:04:52,080
It looks like the download hasn't started.

70
00:04:52,080 --> 00:04:58,860
I can always click there to manually grab it from source forge dot net and once we do have it installed

71
00:04:59,100 --> 00:05:00,840
we'll explore the very basics.

72
00:05:00,850 --> 00:05:03,930
Throughout the next several videos down below.

73
00:05:03,940 --> 00:05:06,550
It is indeed downloading what we need.

74
00:05:06,550 --> 00:05:12,220
I'm gonna go ahead and run the installer for my operating system and once again this is one of those

75
00:05:12,220 --> 00:05:14,170
click Next installers.

76
00:05:14,260 --> 00:05:20,260
If you're on Windows though at some point throughout the options menu it's going to ask you if you want

77
00:05:20,260 --> 00:05:23,200
to install something called Get bash.

78
00:05:23,200 --> 00:05:28,990
You have to check that option if you don't you're gonna have to reinstall get later in the course to

79
00:05:28,990 --> 00:05:31,270
get access to get bash.

80
00:05:31,270 --> 00:05:36,610
This is going to allow you to perform some operations that you would otherwise not be able to perform

81
00:05:36,640 --> 00:05:37,600
on Windows.

82
00:05:37,600 --> 00:05:45,280
So once again for Windows users only make sure to check the option in the installer that installs get

83
00:05:45,430 --> 00:05:46,400
bash.

84
00:05:46,480 --> 00:05:48,160
Right here I'm on a Mac.

85
00:05:48,220 --> 00:05:50,380
I'm going to double click that installer.

86
00:05:50,440 --> 00:05:56,460
Actually I need to right click it and click open so I can verify that I want to install this software

87
00:05:56,470 --> 00:05:57,090
from the Web.

88
00:05:57,580 --> 00:06:03,100
And once again as mentioned this is just the type of installer where we click Next a few times unless

89
00:06:03,100 --> 00:06:04,060
you're on Windows.

90
00:06:04,060 --> 00:06:07,870
Make sure to check the get bash installation option.

91
00:06:07,930 --> 00:06:13,210
Now once things are done we're gonna go ahead and restart the terminal once again from Visual Studio

92
00:06:13,210 --> 00:06:17,340
code and we're gonna make sure everything got installed correctly.

93
00:06:17,350 --> 00:06:19,290
I'm going to trash the installer.

94
00:06:19,420 --> 00:06:22,180
I'm gonna head over to visual studio code.

95
00:06:22,240 --> 00:06:29,350
I'll use the trash can to close the terminal then I'll open up a new one right here terminal new terminal

96
00:06:29,950 --> 00:06:30,460
from here.

97
00:06:30,460 --> 00:06:36,490
We're gonna use get which is the command we got access to when we installed get we'll be using all sorts

98
00:06:36,490 --> 00:06:40,900
of get commands throughout this section and throughout the rest of the class.

99
00:06:40,960 --> 00:06:46,450
All we're going to do in this video is make sure it installed correctly by checking the version we have

100
00:06:46,450 --> 00:06:48,260
installed on our machines.

101
00:06:48,310 --> 00:06:51,370
That is get space hyphen hyphen version.

102
00:06:51,370 --> 00:06:57,190
If I run this it's gonna print the version of Get I have installed which is two point nineteen point

103
00:06:57,250 --> 00:06:58,010
two.

104
00:06:58,060 --> 00:07:04,420
Now the exact version of Get you're using is not particularly important as long as you're using V2 or

105
00:07:04,420 --> 00:07:05,140
greater.

106
00:07:05,260 --> 00:07:09,690
If you're seeing v 0 or v 1 as that first number that's a problem.

107
00:07:09,790 --> 00:07:13,800
Now you shouldn't be seeing that as you just installed the tool.

108
00:07:13,960 --> 00:07:19,090
So right here we do indeed have get installed correctly and throughout the section we're gonna start

109
00:07:19,090 --> 00:07:24,580
to put our project under version control to keep track of its changes over time.

110
00:07:24,700 --> 00:07:30,010
Then we're gonna be able to take those changes and we're gonna be able to send them off to the github

111
00:07:30,010 --> 00:07:34,510
servers and the Heroku servers by running commands from the terminal.

112
00:07:34,510 --> 00:07:40,000
That is how we're gonna send our code off to those third party services.

113
00:07:40,000 --> 00:07:46,000
Now we're gonna talk more about what get is and how it's going to work for our application files in

114
00:07:46,000 --> 00:07:47,720
the very next video.

115
00:07:47,740 --> 00:07:49,030
I'm excited to get to that.

116
00:07:49,090 --> 00:07:50,970
So let's go ahead and jump right in.
