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!

Data fetching is a crucial part of any web application. In this episode of DejaVue, we discuss the different ways to fetch data in Vue.js and Nuxt.js, and how to cache it.

We also talk about the experimental Suspense feature in Vue.js and how it can be used to improve the user experience, as well as how to handle third-party scripts in your application.

In addition, Nuxt's data fetching options are discussed, including the $fetch method, useFetch, useAsyncData and the useNuxtData composable. Finally, we cover server-side caching in Nuxt.js, including route rules, defineCachedEventHandler, and defineCachedFunction.
