1
00:00:00,540 --> 00:00:05,700
In this video, we are going to see Prerequisites three, which is the Node.js.

2
00:00:06,300 --> 00:00:13,320
Node.js is an open source, cross-platform backend JavaScript runtime environment that runs on the V8

3
00:00:13,320 --> 00:00:17,370
engine and executes JavaScript code outside a web browser.

4
00:00:18,160 --> 00:00:23,410
So during the course we will develop our Lambda Microservices with Node.js runtime.

5
00:00:23,410 --> 00:00:26,080
So that's why we should download Node.js.

6
00:00:26,320 --> 00:00:33,460
Also, when developing infrastructure with a SDK, it is also required because we will use NPM node

7
00:00:33,580 --> 00:00:36,850
package management and developing with the typescript.

8
00:00:36,850 --> 00:00:40,450
So Node.js is our core prerequisites during the course.

9
00:00:40,690 --> 00:00:49,210
So both that means we need Node.js, both a Lambda Microservice development and also a SDK infrastructure

10
00:00:49,240 --> 00:00:54,130
development with TypeScript code for infrastructure as code best practices.

11
00:00:55,840 --> 00:00:56,170
Okay.

12
00:00:56,170 --> 00:00:58,480
Let's go and download Node.js.

13
00:00:58,660 --> 00:01:01,990
Let's start with downloading node command.

14
00:01:02,230 --> 00:01:06,850
Open the command window and you can check the Node.js version.

15
00:01:08,820 --> 00:01:11,340
Open the command window.

16
00:01:11,430 --> 00:01:16,200
Before we installed, I would like to check not the stage version.

17
00:01:16,200 --> 00:01:20,040
If you have not earlier, you can check the node version.

18
00:01:20,040 --> 00:01:25,800
Yes, I have already downloaded before and I have seen that 16 version of Node.js.

19
00:01:25,800 --> 00:01:32,550
But even though I would like to download again with the latest version, if you have already installed

20
00:01:32,550 --> 00:01:41,160
Node.js before, then you should check the version because a double SDK uses the Node.js greater than

21
00:01:41,160 --> 00:01:47,250
the 10th version and exit for the versions 13 and the 13 six.

22
00:01:48,000 --> 00:01:51,870
So a version is active long term support and is recommended.

23
00:01:51,870 --> 00:01:57,900
So it is recommended that we should download the Lta's long term support version of Node.js.

24
00:01:58,230 --> 00:02:05,910
So I can say that it's good to use latest, latest version if you have already installed, please update.

25
00:02:05,910 --> 00:02:18,360
So let's go to the node dot org address URL and you can download the Ltsc version I'm going to download.

26
00:02:19,410 --> 00:02:20,250
This version.

27
00:02:23,520 --> 00:02:24,390
Okay.

28
00:02:24,750 --> 00:02:29,850
Collect these installments and follow the instruction correctly.

29
00:02:29,850 --> 00:02:30,750
Next button.

30
00:02:31,170 --> 00:02:31,890
Agree.

31
00:02:31,920 --> 00:02:32,730
Next.

32
00:02:32,880 --> 00:02:33,750
Next.

33
00:02:34,050 --> 00:02:34,800
Next.

34
00:02:35,710 --> 00:02:41,880
And next uninstall or it is also required for the permission.

35
00:02:41,980 --> 00:02:42,500
Okay.

36
00:02:42,520 --> 00:02:44,470
We are going to install Node.js now.

37
00:02:45,130 --> 00:02:48,340
Long term support for the windows.

38
00:02:48,640 --> 00:02:54,910
You can download as per your operating system, but make sure that you are download latest version.

39
00:02:55,880 --> 00:02:56,690
Okay.

40
00:02:59,300 --> 00:03:01,640
Yes it is successfully installed.

41
00:03:01,670 --> 00:03:05,750
Click to finish and verify that with your.

42
00:03:06,670 --> 00:03:09,400
Command window, not the stage version.

43
00:03:09,490 --> 00:03:18,490
Execute this command and see that I'm using 16, 14 and to the latest version when I recording this

44
00:03:18,490 --> 00:03:19,030
course.

45
00:03:19,030 --> 00:03:23,530
But the idea is you can download the latest version when you are watching this video.

46
00:03:25,060 --> 00:03:28,720
As you can see that we have successfully, successfully installed Node.js.

47
00:03:28,750 --> 00:03:31,510
Let's see the next prerequisites for our project.
