Global Packages Installation

Once you have downloaded NodeJS, open NodeJS command prompt and write a simple command as shown below.



Once you run this command, ReactJS and its global package will install at your system. In this command, –g is used to make this package global so that we can run it from any location.

You can see in the above image, a process bar is running. Once all processes are completed, the app will be created as shown in the below image.



Start npm

The next step is to run npm, which can be done by simply using two commands

1. cd environmentsetupdemo- Where environmentsetupdemo is app name.
2. npm start

Once you enter this command, Node.js command prompt will give you the following screen.
