00:00:00,210 --> 00:00:06,780
In this lecture, we're going to install the angular Seelye building an application is going to require

2
00:00:06,780 --> 00:00:08,130
dozens of tools.

3
00:00:08,460 --> 00:00:12,270
It's never a pleasant experience configuring various tools.

4
00:00:12,570 --> 00:00:18,720
However, it's a step we must take if we want to debug, build and deploy our project.

5
00:00:19,020 --> 00:00:23,550
Luckily, we can skip this step altogether with the angular ceiling.

6
00:00:24,210 --> 00:00:30,840
The Angular Seelye is an official tool by the angular team for configuring the tools required for running

7
00:00:30,840 --> 00:00:32,340
an angular application.

8
00:00:32,700 --> 00:00:37,050
By using this tool, we can start working on our application right away.

9
00:00:37,680 --> 00:00:41,310
The Seelye is capable of automating other tasks, too.

10
00:00:41,670 --> 00:00:47,580
It can build our project, start a development server, run tests and deploy an app.

11
00:00:47,910 --> 00:00:51,330
It's one of the most exhaustive tools Angular has to offer.

12
00:00:51,630 --> 00:00:57,180
As you will see, there are hundreds of options for managing our project with the Seelye.

13
00:00:57,750 --> 00:01:03,870
Let's briefly talk about how this really works under the hood during the development of our application.

14
00:01:03,900 --> 00:01:06,060
We're going to have dozens of files.

15
00:01:06,360 --> 00:01:12,150
They can range from TypeScript files to images and fonts as we write our code.

16
00:01:12,390 --> 00:01:15,180
They'll be processed through the angular seelye.

17
00:01:15,540 --> 00:01:21,240
In reality, the Seelye is a tool that manages other tools just to name a few.

18
00:01:21,330 --> 00:01:27,420
The tools are Web Pack, Babel, SAS and TypeScript, along with other tools.

19
00:01:27,750 --> 00:01:32,070
You don't need to know how these tools work to be able to work with Angular.

20
00:01:32,370 --> 00:01:34,620
That's one of the perks of using a framework.

21
00:01:34,800 --> 00:01:39,780
It handles the configuration for these tools, thus saving you hours of time.

22
00:01:40,530 --> 00:01:44,790
The purpose of running our code through these tools is to produce a bundle.

23
00:01:45,090 --> 00:01:49,020
The bundle is the application code that's been optimized for production.

24
00:01:49,410 --> 00:01:51,930
These files can be uploaded to a server.

25
00:01:52,230 --> 00:01:56,880
Overall, the SEELYE is a utility tool for managing projects.

26
00:01:58,860 --> 00:02:05,130
In the resource section of this lecture, I provide a link to the documentation page for the angular

27
00:02:05,130 --> 00:02:05,850
Seelye.

28
00:02:06,330 --> 00:02:10,110
Everything we need to know about this tool can be found on this page.

29
00:02:10,560 --> 00:02:15,210
One of the first sections on this page is the installation instructions.

30
00:02:15,720 --> 00:02:19,080
It's recommending we install these C align with 21:00.

31
00:02:19,380 --> 00:02:21,420
Let's copy the command they give us.

32
00:02:23,840 --> 00:02:29,000
Next, switch over to the command pace and run the command we copied earlier.

33
00:02:29,300 --> 00:02:31,030
If you're on a Mac or Linux.

34
00:02:31,070 --> 00:02:34,910
Be sure to add the pseudo command before installing the package.

35
00:02:35,180 --> 00:02:37,040
The installation may take a while.

36
00:02:37,160 --> 00:02:38,000
Be patient.

37
00:02:43,010 --> 00:02:46,960
The installation should be complete if you get a couple of warnings.

38
00:02:47,030 --> 00:02:48,350
That's completely normal.

39
00:02:48,620 --> 00:02:54,470
We can verify if the insulation was a success by typing the energy version command.

40
00:02:57,000 --> 00:03:00,690
This command will output the version of the package we've installed.

41
00:03:00,930 --> 00:03:04,950
In addition, it'll provide information on the environment we're running in.

42
00:03:05,220 --> 00:03:09,060
It's likely be versions of your environment will be different than mine.

43
00:03:09,420 --> 00:03:14,340
That's perfectly fine as long as the ceiling, too is working on your machine.

44
00:03:15,120 --> 00:03:20,160
The nji command we've typed was created when we installed the Seelye package.

45
00:03:20,700 --> 00:03:27,040
Any time we want to work with the Seelye, we need to type energy, followed by the Sub Command.

46
00:03:27,060 --> 00:03:32,370
We'd like to run the version command is just one of the many commands from this tool.

47
00:03:32,910 --> 00:03:37,830
The Seelye has another command for viewing a list of commands and options.

48
00:03:38,100 --> 00:03:41,020
Let's check it out inside the command line.

49
00:03:41,040 --> 00:03:43,710
We will run the Nji Help Command.

50
00:03:46,270 --> 00:03:52,420
This command will immediately output a list of commands available from the angular Seelye package,

51
00:03:52,690 --> 00:03:58,600
we can perform actions such as deployments, running tests or creating a new project.

52
00:03:58,960 --> 00:04:05,710
Feel free to explore these commands in the next lecture, we're going to use the Seelye to install a

53
00:04:05,710 --> 00:04:07,690
fresh, angular application.
