useBreadcrumbItems()

The useBreadcrumbItems() composable is a way to generate an automatic breadcrumb list that helps users to navigate between pages.

• Integrates with Nuxt Schema.org to generate BreadcrumbList structured data.
• Integrates with Nuxt I18n to generate localized breadcrumbs.

Demo

<script lang="ts" setup>
const links = useBreadcrumbItems() // uses the current route
</script>

<template>
  <UBreadcrumb :links="links" />
</template>

Modifying Breadcrumbs

Because the breadcrumb is generated automatically, you may need to modify the final output.

It's important to do this within the defineBreadcrumbItems function, as it will ensure that the Schema.org is generated correctly.

Route Meta

If you need to modify the breadcrumb for a specific static route, you can use the breadcrumb property of the route meta.

<script lang="ts" setup>
definePageMeta({
  breadcrumb: {
    icon: 'i-heroicons-home',
    ariaLabel: 'Home'
  },
})
</script>

Overrides

When you need more control over the final output, you can use the overrides prop. This allows you to override any part of the breadcrumb.

The property takes an array of either: BreadcrumbItem, false or undefined, the array of overrides is applied in the order they are provided.

When providing undefined, nothing will be overridden. When providing false, the breadcrumb will be removed.

For example, if you have the path /blog/my-post and you want to override the my-post segment, we need to target the third item in the array.

// path: /blog/my-post will generate ['Home', 'Blog', 'My Post']
useBreadcrumbItems({
  overrides: [
    undefined, // Home
    undefined, // Blog
    {
      label: 'My Awesome Post',
      to: '/blog/my-post',
      icon: 'i-heroicons-home'
    }
  ]
})

append and prepend

If you need to add items to the end or beginning of the breadcrumb, you can use the append and prepend props.

useBreadcrumbItems({
  append: [
    {
      label: 'Final Link'
    }
  ]
})

I18n Integration

If you're using the @nuxtjs/i18n module, you can use the key breadcrumbs.items.${routeName}.

Where routeName is the generated name of the Vue Router route.

export default {
  breadcrumb: {
    items: {
      index: {
        icon: 'i-heroicons-home',
        ariaLabel: 'Home'
      }
    }
  }
}
