In this video, we are going to see Prerequisites three, which is the Node.js.
Node.js is an open source, cross-platform backend JavaScript runtime environment that runs on the V8
engine and executes JavaScript code outside a web browser.
So during the course we will develop our Lambda Microservices with Node.js runtime.
So that's why we should download Node.js.
Also, when developing infrastructure with a SDK, it is also required because we will use NPM node
package management and developing with the typescript.
So Node.js is our core prerequisites during the course.
So both that means we need Node.js, both a Lambda Microservice development and also a SDK infrastructure
development with TypeScript code for infrastructure as code best practices.
Okay.
Let's go and download Node.js.
Let's start with downloading node command.
Open the command window and you can check the Node.js version.
Open the command window.
Before we installed, I would like to check not the stage version.
If you have not earlier, you can check the node version.
Yes, I have already downloaded before and I have seen that 16 version of Node.js.
But even though I would like to download again with the latest version, if you have already installed
Node.js before, then you should check the version because a double SDK uses the Node.js greater than
the 10th version and exit for the versions 13 and the 13 six.
So a version is active long term support and is recommended.
So it is recommended that we should download the Lta's long term support version of Node.js.
So I can say that it's good to use latest, latest version if you have already installed, please update.
So let's go to the node dot org address URL and you can download the Ltsc version I'm going to download.
This version.
Okay.
Collect these installments and follow the instruction correctly.
Next button.
Agree.
Next.
And next uninstall or it is also required for the permission.
Okay.
We are going to install Node.js now.
Long term support for the windows.
You can download as per your operating system, but make sure that you are download latest version.
Okay.
Yes it is successfully installed.
Click to finish and verify that with your.
Command window, not the stage version.
Execute this command and see that I'm using 16, 14 and to the latest version when I recording this
course.
But the idea is you can download the latest version when you are watching this video.
As you can see that we have successfully, successfully installed Node.js.
Let's see the next prerequisites for our project.
