Why IE 11 display blank page rendering react app

Why IE 11 display blank page rendering react app

If you are experiencing a blank page while rendering a React app on Internet Explorer 11, then there might be some issues with the compatibility of the browser with the JavaScript code of the application.

Possible Reasons:

• Missing Polyfills: Internet Explorer 11 doesn't support some of the modern JavaScript features used in React. Therefore, you need to add polyfills for these features. But if you forget to add them, it won't work on IE 11, resulting in a blank page.
• Broken JavaScript: Internet Explorer 11 is a slightly outdated browser and doesn't support some of the modern JavaScript syntax used in React. If there is any syntax error in your JavaScript code, it won't work on IE 11 and will show a blank page.
• Different Rendering Engine: Internet Explorer 11 uses a different rendering engine than other modern browsers. Therefore, some of the CSS styles may not work as expected, causing a blank page to appear.

Solutions:

Here are some possible solutions to fix the blank page issue:

• Add Polyfills: You can add polyfills for the missing JavaScript features using tools like babel-polyfill or core-js. By using these tools, you can make your code compatible with Internet Explorer 11.
• Use ES5 Syntax: Since Internet Explorer 11 doesn't support some of the modern JavaScript syntax, you should use ES5 syntax instead. You can use tools like Babel to convert your modern JavaScript code into ES5 syntax.
• Reset CSS: You can try resetting the CSS of your React app using a CSS reset like normalize.css. This will ensure that your styles work as expected on different browsers, including Internet Explorer 11.
• Use a Different Browser: If all else fails, you can recommend the user to use a different browser instead of Internet Explorer 11.

// Example code for adding polyfills
import 'babel-polyfill';
import 'core-js/es6/map';
import 'core-js/es6/set';

By following these solutions, you can make your React app compatible with Internet Explorer 11 and avoid the blank page issue.
