It is recommended to choose the LTS version for stability and compatibility with most applications. Click on the “LTS” button to download the installer for the latest LTS version of Node.js.

Run the installer: Once downloaded, locate the file and double-click on it to run it.

  1. Choose installation options: On the Node.js installer window, you will be presented with a few options. Keeping the default options selected, including the checkbox, to automatically install the necessary tools for Node.js development is recommended.
  2. Select the installation location: Choose the folder where you want to install Node.js. The default location is commonly acceptable, but you can choose a different location.
  3. Complete the installation: To finish the installation process, press the “Next” button, then follow the directions on the screen.
  4. Verify the installation: After completing the installation, open the command prompt (or PowerShell) and type the following command: node -v. This command will display the version of Node.js installed on your system. Similarly, you can run npm -v to verify npm installation (Node Package Manager).

That’s it! Node.js should now be successfully installed on your Windows machine. You can start using Node.js and npm to develop and run JavaScript applications.

Please note that the installation steps may vary slightly depending on the specific version of Node.js and your Windows operating system.

Setting up Create React App

Here is a step-by-step guide to setting up Create React App:

  1. Install Node.js and NPM: Create React App requires Node.js and NPM to be installed. If you still need to install them, please see my previous response for instructions on installing Node.js.
  2. Open your terminal: Open your terminal (e.g., Command Prompt, PowerShell, or Terminal) on your computer.
  3. Install Create React App: Install Create React App by running the following command in your terminal: 

npm install -g create-react-app

  1. Create a new React project: Create a new React project with Create React App by running the following command in your terminal:

create-react-app my-app 

Rename “my-app” with the desired name for your project.

  1. Start the development server: Change to the project directory by running the following command in your terminal: 

cd my-app

  1. Then start the development server with the following command: 

npm start 

That will start a local web server and open your new React application in a new browser window.

  1. Begin development: You can now begin developing your React application. Changes you use to the code will automatically reload the application in your browser.

That’s it! You have successfully set up Create React App and started a new React project.

Creating a New React Project

Now that you have Create React App installed, let’s create a new React project by following these steps:

  1. Choose or create a directory where you want your project to be located.
  2. Open the Command Prompt or your preferred terminal.
  3. Use the cd (change directory) command to navigate to the desired directory. For example, if your project directory is in the Documents folder, you would type: cd Documents.
  4. Once inside the desired directory, enter the following command and press Enter: create-react-app my-react-project (Replace “my-react-project” with your preferred project name).
  5. Sit back and relax while Create React App sets up the project structure and installs all the necessary dependencies. That may take a few moments, depending on your internet connection speed.

Once the scaffolding and dependency installation is complete, you can embark on your React journey with the newly created project. Enjoy exploring the wonderful world of React JS!

Testing Your React Installation

To verify that React JS is correctly installed on your Windows system, follow these steps to run the sample React project:

  1. Launch the Command Prompt or your preferred terminal.
  2. Use the cd command to navigate to your project’s directory.
  3. Once inside the project directory, type npm start and press Enter.
  4. After a brief moment, your default web browser should automatically open. You should see the React app running on a local development server.

If everything goes smoothly and you can view the React app without errors, congratulations! You’ve successfully installed React JS in your Windows environment. Now you can start creating your own excellent React applications.

Troubleshooting Common Issues

Here are some common issues that might arise during the installation process of React JS on Windows, along with their solutions:

“Node.js is not recognized as an internal or external command” error: If you encounter this error while installing or using React JS on Windows, your system does not recognize Node.js. To correct it, review that Node.js is set up correctly and that its bin folder is added to the PATH environment variable. You may add the bin folder using the following:

  • Click on the menu and search for “Environment Variables.”
  • Click on “Edit the system environment variables.”
  • Click on the “Environment Variables” button.
  • Under “System variables,” scroll down and find “Path.”
  • Click on “Edit” and then on “New.”
  • Type in the path to the bin folder of Node.js (e.g., “C:\Program Files\nodejs\bin”).
  • Click “OK” to close all the windows.
  1. “npm ERR! Code INTEGRITY” error: If you encounter this error at the end of the React JS installation process, there is a problem with the installation package. To resolve this error, try deleting the node_modules directory in your React project and reinstalling the packages by running npm install.
  2. React JS application does not run: It might be a script error if it does not run after installation. To solve the issue, try running npm install to ensure the necessary packages are installed. You can also check the console log in your browser’s developer tools to identify script errors.
  3. “Command not found” error: If you encounter this error when running React JS commands, the terminal cannot locate the command. This error usually occurs when the necessary packages are not installed. To resolve this error, ensure that Node.js and NPM are installed correctly, and their paths are added to the PATH environment variable, as mentioned in point.
