Changing the favicon in a React application is a simple process and can be achieved in a few steps. Here’s a step-by-step tutorial:
Step 1: Prepare the Icon
Make sure you have an icon in the desired format (.ico, .png, etc.). You can create an icon using online tools or graphic design programs like Photoshop, Illustrator, or even online editors like Favicon.io.
Step 2: Place the Icon in the public Folder
In the root directory of your React project, look for the folder named public. Place your icon file in this folder. Ensure that the file name is easy to remember, such as favicon.ico or myicon.png.
Step 3: Modify the public/index.html File
Open the public/index.html file in your favorite code editor. This file is the HTML entry point for your React application.
Inside the <head> tag, add the following line just before closing the </head> tag. Make sure to replace 'favicon.ico' with the name of your icon file if it’s different:
<link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
If you’re using a different image format, adjust the file extension accordingly (e.g., .png).
Step 4: Restart the React Application
Save the changes to the public/index.html file and close the file. Stop the React development server (if running) by pressing Ctrl + C in the terminal. Then, restart your application with the following command:
npm start
or if you’re using Yarn:
yarn start
Step 5: Verify the Change
Open your application in the browser and check that the favicon has been updated. Make sure to clear the browser cache or reload the page if you don’t see the changes immediately.
Done! You have successfully changed the favicon of your React application. This small personal touch can make your application more recognizable and appealing to users.
