How to intercept/log server side errors?

Hey, I am trying to send notifications to the dev team server whenever there's an unexpected error on the backend (500 errors) but i am not sure how.

Hi @Felix. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To intercept and log server-side errors in Nuxt, you have several options. Here's how you can approach this: 1. Use Nitro App Hooks: Nuxt uses Nitro as its server engine, which provides hooks for error handling. You can use the error hook to capture all server-side errors. Here's an example: 
   export default defineNitroPlugin((nitroApp) => {
     nitroApp.hooks.hook('error', (error, { event }) => {
       // Your error logging logic here
       console.error('Server error:', error)
       // Send notification to dev team
     })
   })
   
   export default defineNitroPlugin((nitroApp) => {
     nitroApp.hooks.hook('error', (error, { event }) => {
       // Your error logging logic here
       console.error('Server error:', error)
       // Send notification to dev team
     })
   })
Place this code in a file under the server/plugins/ directory. This hook will be called whenever an error occurs on the server side. Source: Nitro App Hooks (runtime, server-side) 2. Use the onErrorCaptured hook: For Vue-specific errors, you can use the onErrorCaptured hook in a plugin: 
   export default defineNuxtPlugin((nuxtApp) => {
     nuxtApp.vueApp.config.errorHandler = (error, instance, info) => {
       // Handle error, e.g. send to a service
     }

     nuxtApp.hook('vue:error', (error, instance, info) => {
       // Handle error, e.g. send to a service
     })
   })
   
   export default defineNuxtPlugin((nuxtApp) => {
     nuxtApp.vueApp.config.errorHandler = (error, instance, info) => {
       // Handle error, e.g. send to a service
     }

     nuxtApp.hook('vue:error', (error, instance, info) => {
       // Handle error, e.g. send to a service
     })
   })
Source: Error Handling 3. Customize the error page: You can create a custom error page by adding an error.vue file in your project's root directory. In this file, you can handle errors and potentially send notifications: 
   <script setup lang="ts">
   import type { NuxtError } from '#app'

   const props = defineProps({
     error: Object as () => NuxtError
   })
// You can add your notification logic here
   // For example, send a notification if it's a server error (500)
   if (props.error.statusCode === 500) {
     // Send notification to dev team
   }
   </script>

   <template>
     <div>
       <h2>{{ error.statusCode }}</h2>
       <!-- Error display logic -->
     </div>
   </template>
   
   <script setup lang="ts">
   import type { NuxtError } from '#app'

   const props = defineProps({
     error: Object as () => NuxtError
   })
// You can add your notification logic here
   // For example, send a notification if it's a server error (500)
   if (props.error.statusCode === 500) {
     // Send notification to dev team
   }
   </script>

   <template>
     <div>
       <h2>{{ error.statusCode }}</h2>
       <!-- Error display logic -->
     </div>
   </template>
Source: Error Handling Remember to implement the actual notification sending logic (e.g., using an API call to your notification service) in these error handlers. Also, consider using a logging service or error tracking tool that can automatically capture and report server-side errors. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
