How To Install React JS in Windows?

To install React, we first need to install Node.js and npm. So, let’s start by installing NodeJS. Or, if you already have NodeJS installed, directly jump to Step 12.

Step 1: To install NodeJS visit Node.js (nodejs.org) and download the LTS (Long Term Support) version.

Step 2: Once downloaded, open the '.msi' file. If a question arises, 'Do you want to allow this app to make changes to your device?'.Then you can click 'Yes.'

Step 3: After clicking ‘Yes’, you will see the below prompt. Click ‘Next’.

Step 4: Mark the checkbox Accept the agreement and click 'Next'.

Step 5: Confirm the destination folder and click 'Next.' It is preferred to keep the settings default.

Step 6: Click on ‘Next’.

Step 7: If you want to install additional tools to be installed mark the check box and click ‘Next'. Else, you can simply click on 'Next’. (It is recommended to keep the box unchecked and click Next).

Step 8:  Now our NodeJS is ready to install, click ‘Install’.

Step 9: Going through the installation process.

Step 10: After completing the NodeJS installation, click 'Finish’.

Step 11: Type 'node -v' on the command prompt to check if the installation is successful. As npm also comes with NodeJS, we don't need to install it explicitly. To check if it's installed, Type 'npm -v.'

Our NodeJS and npm installation is successful in both the versions listed above.

Now we will head toward the installation of ReactJS. To install React, we will move into IDE. For this demo, we have used VS Code.

Step 12: Open the VS Code and create a new terminal.

Step 13: Make a new folder first_react_app using the command' mkdir first_react_app' and move to that folder by typing the command 'cd first_react_app'. Here we have given a name first_react_app. You can name it any.

As you can see, we are now in the folder we just created.

Step 14:  We will now install the Create React App package using the 'npm install -g create-react-app' command. In this command, '-g' stands for global installation, so you don't have to install it repeatedly.

To check if the installation is successful, type ‘create-react-app –version'. The version is listed below, and our installation is successful.

Step 15: We will create another folder to store all dependencies in a single folder using the command' create-react-app myreact'. Here 'myreact' is just a folder name; you can name it any.

Based on your internet speed, it may take a few moments to complete. You will see the above output in your terminal if everything works well.

Step 16: Hold On !!! We are in the last stage of react installation. Now move to the folder we just created, 'myreact', using the command 'cd myreact'. Type the ' npm start ' command once you have moved inside the folder. If everything goes well, you will see your browser's output below and the ReactJS logo.

Kudos !! We are done with the ReactJS installation. Now you are ready to create interactive and exciting UIs using ReactJS.
