Nuxt Content v3 layouts

I'm migrating my project from Nuxt Content v2 to v3, and almost every page in my project uses a layout. Unfortunately, there's an issue with this: when navigating to another subpage (without a hard reload), the layout glitches, sometimes duplicates, and so on. To check the layout on each page, I'm forced to create a collection that includes all possible .md files: content: defineCollection({ type: 'page', source: '*/**.md' }), so that I can use: const route = useRoute() const { data: page } = await useAsyncData(route.path, async () => { return queryCollection('content').path(route.path).first() }) so that I can later use: <NuxtLayout :name="page?.meta?.layout || 'default'"> <NuxtPage /> </NuxtLayout> After navigating to /getting-started/usage and then clicking a button that redirects to /getting-started/test, the layout does not update. However, if I do a hard refresh, it loads correctly. How should I properly handle layouts in this case? And - is there an alternative approach to the Document-Driven mode that doesn’t require creating a collection of ALL md files? Wouldn't this duplicate content in the database? I’m using this collection only for [..slug].vue to display the correct page based on the URL. What can be done about this? Maybe I’m using the new features incorrectly, or is this a bug? PS. how can I prevent these types of issues in the future, where a hard refresh behaves completely differently from a regular navigation—especially during development? github issue: https://github.com/nuxt/content/issues/3107

Hi @FoxCode. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, I can offer some insights and suggestions regarding your Nuxt Content v3 layout issues and document-driven mode concerns. Let's address your questions one by one: 1. Handling layouts properly: The issue you're experiencing with layouts glitching or duplicating when navigating between pages is likely related to how layouts are being applied and updated. In Nuxt 3, layouts are handled differently compared to Nuxt 2. To properly handle layouts, you can try the following approach: a. Define your layouts in the layouts directory. b. Use definePageMeta in your pages to specify the layout for each page. c. Use <NuxtLayout> in your app.vue file to wrap your <NuxtPage>. Here's an example of how to set up your app.vue: 
<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>
<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>
And in your pages: 
<script setup>
definePageMeta({
  layout: 'custom'
})
</script>
<script setup>
definePageMeta({
  layout: 'custom'
})
</script>
This approach should help prevent layout glitches during navigation. 2. Alternative to Document-Driven mode: Yes, there is an alternative approach to the Document-Driven mode that doesn't require creating a collection of all MD files. According to the Content v3 migration guide, you can implement a similar functionality by creating a catch-all page and fetching content based on the route path. Here's an example: 
<script lang="ts" setup>
const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})
</script>

<template>
  <div>
    <header><!-- ... --></header>

    <ContentRenderer v-if="page" :value="page" />

    <footer><!-- ... --></footer>
  </div>
</template>
<script lang="ts" setup>
const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})
</script>

<template>
  <div>
    <header><!-- ... --></header>

    <ContentRenderer v-if="page" :value="page" />

    <footer><!-- ... --></footer>
  </div>
</template>
This approach allows you to fetch and render content based on the current route without creating a collection of all MD files. 3. Preventing issues with hard refresh vs. regular navigation: To prevent issues where a hard refresh behaves differently from regular navigation, especially during development, consider the following: a. Ensure that your content is being properly loaded and cached on the client-side after initial server-side rendering. b. Use useAsyncData or useLazyAsyncData consistently to fetch content, as shown in the example above. c. Make sure your layouts are properly defined and applied using the definePageMeta approach mentioned earlier. d. Consider using the <ClientOnly> component for content that should only be rendered on the client-side to avoid hydration mismatches. It's worth noting that the behavior you're experiencing might be related to how Nuxt Content v3 handles content fetching and rendering. If you continue to experience issues after implementing these suggestions, it may be worth reporting it as a potential bug to the Nuxt Content team. For further assistance and up-to-date information, I recommend checking the Nuxt Content v3 documentation and the Nuxt 3 layouts documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I cant do something like this: const route = useRoute() const { data: page } = await useAsyncData(route.path, () => { return queryCollection('content').path(route.path).first() }) definePageMeta({ layout: page.value?.meta?.layout ?? "default" }) Because Await expressions are not supported in definePageMeta

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct, and I apologize for any confusion in my previous response. You're right that you can't use await expressions or dynamic values directly in definePageMeta. This is because definePageMeta is a compiler macro that is processed at build time, not at runtime. Let me provide a more appropriate solution for your situation. Based on the Nuxt documentation on layouts, there are a couple of approaches you can take to handle dynamic layouts: 1. Use <NuxtLayout> component with a dynamic name: Instead of trying to set the layout in definePageMeta, you can use the <NuxtLayout> component with a dynamic name in your page component. Here's how you can do it: 
<script setup>
const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})

const layoutName = computed(() => page.value?.meta?.layout || 'default')
</script>

<template>
  <NuxtLayout :name="layoutName">
    <!-- Your page content here -->
  </NuxtLayout>
</template>
<script setup>
const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})

const layoutName = computed(() => page.value?.meta?.layout || 'default')
</script>

<template>
  <NuxtLayout :name="layoutName">
    <!-- Your page content here -->
  </NuxtLayout>
</template>
2. Use setPageLayout utility: Nuxt provides a setPageLayout utility that allows you to change the layout dynamically. You can use this in combination with definePageMeta: 
<script setup>
definePageMeta({
  layout: false, // Disable the default layout
})

const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})

watch(() => page.value?.meta?.layout, (newLayout) => {
  setPageLayout(newLayout || 'default')
}, { immediate: true })
</script>

<template>
  <!-- Your page content here -->
</template>
<script setup>
definePageMeta({
  layout: false, // Disable the default layout
})

const route = useRoute()
const { data: page } = await useAsyncData(route.path, () => {
  return queryCollection('content').path(route.path).first()
})

watch(() => page.value?.meta?.layout, (newLayout) => {
  setPageLayout(newLayout || 'default')
}, { immediate: true })
</script>

<template>
  <!-- Your page content here -->
</template>
This approach uses watch to react to changes in the page data and update the layout accordingly. Both of these methods should allow you to dynamically set the layout based on the content metadata without running into the limitation of definePageMeta. For more information on these approaches, you can refer to the Nuxt documentation on layouts and the setPageLayout utility documentation. Remember that when using dynamic layouts, you need to ensure that all possible layouts are registered and available at build time. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
