Error handling in a React application

There are many types of errors that can occur in a React application. These errors can be caused by a variety of factors, such as bugs in the code, network issues, or problems with the rendering process.

we will demonstrate different types of errors that can occur in a React application and how to handle them.

4 main types of errors

  1. JS runtime errors: These are errors that occur when the code is running. These are the most common type of errors and are usually caused by a mistake in the code, type errors, etc.

  2. Network errors: These are errors that occur when the application is trying to communicate with a server. These errors are usually caused by a problem with the network connection. Often you will handle these errors with a try...catch statement.

  3. React render errors: These are errors that occur when the React application is rendering. These errors are usually caused by a problem with the React code. Missing props, undefined variables, etc.

  4. Routing errors: These are errors that occur when the application is trying to navigate to a different page. These errors are usually caused by a problem with the routing configuration. Missing routes, incorrect paths, etc.

Try to clone and run the demo to see how the different types of errors are handled in a React application.

There will also be more information on how to handle these errors in the Readme file of the demo.
