Do you know that your React app deployed on production can crash anytime due to unhandled errors?

React Error Boundaries are here to save your day!

Whenever any type of error happens during the rendering of a component or in lifecycle methods, React displays a blank page without showing any error message.

And getting a blank page on the production site is definitely not a good user experience.

So React Error Boundaries provide a powerful mechanism to catch and gracefully handle errors that occur during the rendering lifecycle of your components.

What is Error Boundary In React

Error boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed.

Error boundaries catch errors during rendering, in lifecycle methods, and in constructors of the whole tree below them.

So watch the above youtube video to learn how to fix this issue.
