Development server of create-react-app does not auto refresh

If you are a JavaScript developer using create-react-app for your projects, you may have encountered a situation where the development server does not automatically refresh when you make changes to your code. This can be frustrating and time-consuming, as you have to manually refresh the page every time you want to see the updated changes.

Fortunately, there are a few solutions to this problem that you can try:

Solution 1: Disable service workers

Create-react-app uses service workers by default to provide offline support and caching. However, these service workers can sometimes interfere with the automatic refreshing of the development server. To fix this issue, you can disable the service workers in your development environment.

To disable service workers, open the src/index.js file in your project and comment out or remove the following lines of code:

// import * as serviceWorker from './serviceWorker';
// serviceWorker.unregister();

After making this change, save the file and restart the development server. The auto-refresh functionality should now work as expected.

Solution 2: Clear browser cache

In some cases, the browser cache can prevent the development server from detecting changes in your code. To resolve this, you can try clearing the browser cache.

Each browser has a different method for clearing the cache, but you can usually find it in the browser’s settings or preferences. Once you have cleared the cache, restart the development server and see if the auto-refresh issue is resolved.

Solution 3: Use a different browser

If the above solutions do not work, you can try using a different browser for development. Sometimes, certain browsers may have compatibility issues with the development server’s auto-refresh functionality.

Install a different browser, such as Firefox or Chrome, and try running your create-react-app project in that browser. This can help determine if the issue is specific to your current browser.

With these solutions, you should be able to resolve the issue of the development server not auto-refreshing in create-react-app. Remember to save your code changes, restart the server, and clear the browser cache if necessary.

Happy coding!
