On creating Breadcrumbs

Let's say, we have a route structure like this: 
// home
definePageMeta({
  breadcrumb: {
    label: 'Go to home' // may be populated from an API
  }
})
// home
definePageMeta({
  breadcrumb: {
    label: 'Go to home' // may be populated from an API
  }
})
// home/first-level
definePageMeta({
  breadcrumb: {
    label: 'Custom label for first level route' // may be populated from an API
  }
})
// home/first-level
definePageMeta({
  breadcrumb: {
    label: 'Custom label for first level route' // may be populated from an API
  }
})
// home/first-level/second-level
definePageMeta({
  breadcrumb: {
    label: 'Custom label for second level route' // may be populated from an API
  }
})
// home/first-level/second-level
definePageMeta({
  breadcrumb: {
    label: 'Custom label for second level route' // may be populated from an API
  }
})
... and so on. Pages have their own metadata and their metadata should be compiled in the breadcrumb: Go to home > Custom label for first level route > Custom label for second level route Another issue is that each route's data comes from an API, along with the customized label for their breadcrumb. The breadcrumb itself is in the Layout, with the header and footer. What's the proper way to handle this scenario? Do we have a way to fetch only the metadata from all routes in the current path, and build the breadcrumb? There is a module (maybe @nuxtjs/seo... ?) that helps with that issue? There are examples of this pattern (on Github) that we can take a look?

Hi @lkjimy. 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 don't have specific information about building breadcrumbs with dynamic metadata from APIs in Nuxt. However, I can share some relevant insights from the available information: Accessing Route Metadata The knowledge sources show that you can define custom metadata using definePageMeta() in your pages. According to a GitHub PR about route groups, route metadata is accessible through useRouter() or within route middlewares via route.meta. Handling Dynamic Data in Page Metadata One challenge you'll face is that definePageMeta() is designed for static metadata extraction at build time. The knowledge sources indicate that page metadata extraction happens during the build process, which means you cannot directly use async API calls within definePageMeta(). Potential Approaches Based on the patterns shown in the knowledge sources: 1. Fetch data separately: You could fetch the breadcrumb labels in your layout component and match them with the current route path. The Stack Overflow post about dynamic routing shows how to access route parameters using useRoute().params. 2. Use composables for dynamic data: As shown in the hydration mismatch example, you can use useFetch() or useLazyFetch() to fetch data that needs to be dynamic. What's Missing The knowledge sources do not explicitly mention: - A built-in breadcrumb solution in Nuxt - Specific modules for breadcrumb generation - Examples of fetching metadata from multiple routes in a path - SEO modules that handle breadcrumbs I recommend checking the official Nuxt documentation or the Nuxt modules ecosystem for breadcrumb-specific solutions, as this information is not available in the provided knowledge sources. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
