What are the best practices for error handling in Vue.js?

In Vue.js, it's essential to handle errors gracefully. Some best practices include using error boundaries, global error handlers, and try-catch blocks.

Can you explain what error boundaries are?

Error boundaries are components that catch JavaScript errors in their child component tree. They prevent the entire app from crashing and allow you to display a fallback UI.

How do I implement a global error handler?

You can implement a global error handler by using Vue.config.errorHandler. This allows you to log errors or display a user-friendly message.

What about handling API errors?

For API errors, you can use try-catch in your async methods and handle different response statuses to provide appropriate feedback to users.
