How to handle error messages based on enviroment?

Hello everyone, has anyone here ever experienced about how we can handle the error message based on environment? so for example if it's on dev, then the message will shown as from the debugging but when it's on production then use a message that looks informative like 'Server is being error now, please try again later'.

Hi @Adnan Erlansyah. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To handle error messages based on the environment in Nuxt, you can use different approaches depending on whether you're dealing with client-side or server-side errors. Here's how you can achieve this: 1. For client-side errors: You can use the <NuxtErrorBoundary> component to catch and handle errors. Inside this component, you can use environment variables to determine which message to display. 
<template>
  <NuxtErrorBoundary>
    <!-- Your content -->
    <template #error="{ error }">
      <p v-if="isDev">{{ error }}</p>
      <p v-else>Server is experiencing an error now, please try again later.</p>
    </template>
  </NuxtErrorBoundary>
</template>

<script setup>
const isDev = process.env.NODE_ENV === 'development'
</script>
<template>
  <NuxtErrorBoundary>
    <!-- Your content -->
    <template #error="{ error }">
      <p v-if="isDev">{{ error }}</p>
      <p v-else>Server is experiencing an error now, please try again later.</p>
    </template>
  </NuxtErrorBoundary>
</template>

<script setup>
const isDev = process.env.NODE_ENV === 'development'
</script>
NuxtErrorBoundary allows you to handle client-side errors and provide custom error messages. 2. For server-side errors: You can use the createError utility to throw errors with different messages based on the environment. In your API routes or server middleware: 
if (process.env.NODE_ENV === 'development') {
  throw createError({
    statusCode: 500,
    message: 'Detailed error message for debugging'
  })
} else {
  throw createError({
    statusCode: 500,
    message: 'Server is experiencing an error now, please try again later.'
  })
}
if (process.env.NODE_ENV === 'development') {
  throw createError({
    statusCode: 500,
    message: 'Detailed error message for debugging'
  })
} else {
  throw createError({
    statusCode: 500,
    message: 'Server is experiencing an error now, please try again later.'
  })
}
createError allows you to create custom error objects with different messages based on the environment. 3. Global error handling: You can create a custom error.vue file in your project root to handle all errors globally. In this file, you can use environment variables to determine which message to display: 
<script setup>
const error = useError()
const isDev = process.env.NODE_ENV === 'development'
const errorMessage = computed(() => {
  if (isDev) {
    return `${error.value.message}\n${error.value.stack}`
  }
  return 'An error occurred. Please try again later.'
})
</script>

<template>
  <div>
    <h1>{{ error.statusCode }}</h1>
    <pre>{{ errorMessage }}</pre>
    <NuxtLink to="/">Home</NuxtLink>
  </div>
</template>
<script setup>
const error = useError()
const isDev = process.env.NODE_ENV === 'development'
const errorMessage = computed(() => {
  if (isDev) {
    return `${error.value.message}\n${error.value.stack}`
  }
  return 'An error occurred. Please try again later.'
})
</script>

<template>
  <div>
    <h1>{{ error.statusCode }}</h1>
    <pre>{{ errorMessage }}</pre>
    <NuxtLink to="/">Home</NuxtLink>
  </div>
</template>
This approach is described in the Nuxt error.vue documentation. By implementing these strategies, you can effectively handle error messages differently based on whether your application is running in development or production environment. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
