Error Handling in Vue

All of you have seen users do weird things with your application and running into strange scenarios - who can't relate to this?
For this and many other reasons, the right way of error handling is important in you application. Join Michael and Alex on a discussion of the different ways one can handle errors in their application.
That includes not always showing an error page, but also handling errors request-based or component-based!

On that note, error messages and how to write decent ones that are helpful for the users are discussed, as well as how components like NuxtErrorBoundary work under the hood

Enjoy the episode!
