00:00:00,240 --> 00:00:05,970
In this lecture, we're going to configure TypeScript Decorators are an experimental feature.

2
00:00:06,270 --> 00:00:10,860
If we want to use decorators, we need to configure TypeScript to enable them.

3
00:00:11,220 --> 00:00:15,150
We can configure TypeScript by creating a configuration file.

4
00:00:15,480 --> 00:00:17,610
This file can be created manually.

5
00:00:18,210 --> 00:00:24,540
Alternatively, the TypeScript package adds a command for creating a basic configuration file.

6
00:00:24,880 --> 00:00:32,220
Let's give the package a try and the command line run the following command NPCs TSC in it.

7
00:00:34,860 --> 00:00:40,980
After running this command, TypeScript will have created a file called T-s Config Dot JSON.

8
00:00:41,250 --> 00:00:42,540
Let's open this file.

9
00:00:45,130 --> 00:00:50,650
Out of the box, TypeScript will recommend dozens of settings for configuring the library.

10
00:00:50,980 --> 00:00:53,620
Luckily, we won't have to configure them all.

11
00:00:53,920 --> 00:00:58,840
The default settings will work for most situations when we switch to Angular.

12
00:00:58,930 --> 00:01:00,950
It'll configure this file for us.

13
00:01:01,270 --> 00:01:07,010
It's not essential to learn every option inside the compiler options object.

14
00:01:07,060 --> 00:01:09,190
We're going to remove every option.

15
00:01:11,810 --> 00:01:14,480
They're not necessary for what we're trying to do.

16
00:01:15,020 --> 00:01:18,860
The option we care about is called experimental decorators.

17
00:01:19,160 --> 00:01:22,640
Let's have this option to the compiler options object.

18
00:01:22,940 --> 00:01:24,710
Its value will be true.

19
00:01:27,440 --> 00:01:32,330
By setting this option too true, we'll be able to write decorators in our files.

20
00:01:32,630 --> 00:01:33,230
That's it.

21
00:01:33,410 --> 00:01:37,940
We've enabled decorators if you're interested in learning the other options.

22
00:01:38,120 --> 00:01:41,240
Check out the link in the resource section of this lecture.

23
00:01:43,730 --> 00:01:50,000
This page will document every option in detail, as you can see, TypeScript is very flexible.

24
00:01:50,300 --> 00:01:53,810
In the next lecture, we're going to begin writing decorators.

25
00:01:54,080 --> 00:01:55,100
I'll see you there.
