Nuxt Content Reference

Last Updated: 2025-11 (v3.8.0)

Check: @nuxt/content in package.json

Nuxt Content v3 is a Git-based CMS that uses SQL-backed collections for querying markdown, YAML, JSON, and CSV files. Perfect for blogs, documentation sites, and content-heavy applications.

Installation & Setup

pnpm add @nuxt/content

nuxt.config.ts:

export default defineNuxtConfig({
  modules: ["@nuxt/content"],

  content: {
    // Optional configuration
    highlight: {
      theme: "github-dark",
      preload: ["typescript", "vue", "bash"],
    },
  },
})

Collections

Defining Collections

Create content.config.ts in your project root:

import { defineCollection, defineContentConfig, z } from "@nuxt/content"

export default defineContentConfig({
  collections: {
    blog: defineCollection({
      type: "page",
      source: "blog/**/*.md",
      schema: z.object({
        title: z.string(),
        description: z.string(),
        date: z.string(),
        tags: z.array(z.string()).optional(),
        author: z.string().optional(),
        image: z.string().optional(),
        draft: z.boolean().default(false),
      }),
    }),

    docs: defineCollection({
      type: "page",
      source: "docs/**/*.md",
      schema: z.object({
        title: z.string(),
        description: z.string(),
        category: z.string().optional(),
      }),
    }),
  },
})

Directory Structure

Querying Collections

queryCollection Composable

The main API for querying content in v3:

<script setup lang="ts">
// Get all articles from 'blog' collection
const { data: articles } = await useAsyncData("articles", () =>
  queryCollection("blog").all(),
)

// Get single article by path
const route = useRoute()
const { data: article } = await useAsyncData("article", () =>
  queryCollection("blog").path(route.path).first(),
)
</script>

<template>
  <div>
    <h1>{{ article?.title }}</h1>
    <ContentRenderer v-if="article" :value="article" />
  </div>
</template>

Query Methods

all()

Get all matching documents:

const posts = await queryCollection("blog").all()

first()

Get first matching document:

const post = await queryCollection("blog").path("/blog/my-post").first()

where()

Filter by field with SQL operators:

// Single condition
const published = await queryCollection("blog").where("draft", "=", false).all()

// Multiple conditions (AND)
const filtered = await queryCollection("blog")
  .where("draft", "=", false)
  .where("category", "=", "tech")
  .all()

andWhere()

Complex AND conditions:

const posts = await queryCollection("blog")
  .where("published", "=", true)
  .andWhere((query) =>
    query.where("date", ">", "2024-01-01").where("category", "=", "news"),
  )
  .all()

orWhere()

OR conditions:

const posts = await queryCollection("blog")
  .where("published", "=", true)
  .orWhere((query) =>
    query.where("featured", "=", true).where("priority", ">", 5),
  )
  .all()

order()

Sort results:

// Descending
const posts = await queryCollection("blog").order("date", "DESC").all()

// Ascending
const posts = await queryCollection("blog").order("title", "ASC").all()

limit()

Limit results:

const latest = await queryCollection("blog")
  .order("date", "DESC")
  .limit(5)
  .all()

skip()

Skip results (for pagination):

const page = 2
const perPage = 10

const posts = await queryCollection("blog")
  .order("date", "DESC")
  .skip((page - 1) * perPage)
  .limit(perPage)
  .all()

select()

Select specific fields:

const posts = await queryCollection("blog")
  .select(["title", "description", "date", "path"])
  .all()

path()

Filter by path:

const post = await queryCollection("blog").path("/blog/my-post").first()

ContentRenderer Component

Renders parsed markdown content (the main component for v3):

<script setup lang="ts">
const route = useRoute()
const { data: post } = await useAsyncData("post", () =>
  queryCollection("blog").path(route.path).first(),
)
</script>

<template>
  <article v-if="post" class="prose dark:prose-invert">
    <h1>{{ post.title }}</h1>
    <ContentRenderer :value="post" />
  </article>
</template>

With error handling:

<script setup lang="ts">
const route = useRoute()
const { data: post, error } = await useAsyncData("post", () =>
  queryCollection("blog").path(route.path).first(),
)

if (error.value || !post.value) {
  throw createError({
    statusCode: 404,
    message: "Post not found",
  })
}
</script>

<template>
  <ContentRenderer :value="post" />
</template>

Common Patterns

Blog List Page

<script setup lang="ts">
const { data: articles } = await useAsyncData("articles", () =>
  queryCollection("blog")
    .where("draft", "=", false)

})

// Filter posts by selected tag
const filteredPosts = computed(() => {
  if (!selectedTag.value) return allPosts.value

  return allPosts.value?.filter((post) =>
    post.tags?.includes(selectedTag.value!),
  )
})
</script>

<template>
  <div>
    <div class="flex gap-2 mb-6">
      <button :class="{ active: !selectedTag }" @click="selectedTag = null">
        All
      </button>
      <button
        v-for="tag of tags"
        :key="tag"
        :class="{ active: selectedTag === tag }"
        @click="selectedTag = tag"
      >
        {{ tag }}
      </button>

    <div class="grid gap-6">
      <article v-for="post of filteredPosts" :key="post.path">
        <h2>{{ post.title }}</h2>
        <p>{{ post.description }}</p>
        <NuxtLink :to="post.path">Read more</NuxtLink>
      </article>
    </div>
  </div>
</template>

Server-Side Queries

Use queryCollection in API routes with event parameter:

// server/api/posts.get.ts
export default defineEventHandler(async (event) => {
  const posts = await queryCollection(event, "blog")
    .where("draft", "=", false)
    .order("date", "DESC")
    .limit(10)
    .all()

  return posts
})

With query parameters:

// server/api/posts/[slug].get.ts
export default defineEventHandler(async (event) => {
  const slug = getRouterParam(event, "slug")

  const post = await queryCollection(event, "blog")
    .path(`/blog/${slug}`)
    .first()

  if (!post) {
    throw createError({
      statusCode: 404,
      message: "Post not found",
    })
  }

  return post
})

Navigation

Use queryCollectionNavigation for generating navigation:

<script setup lang="ts">
const { data: navigation } = await useAsyncData("navigation", () =>
  queryCollectionNavigation("docs"),
)
</script>

<template>
  <nav>
    <ul>
      <li v-for="item of navigation" :key="item.path">
        <NuxtLink :to="item.path">{{ item.title }}</NuxtLink>
        <ul v-if="item.children">
          <li v-for="child of item.children" :key="child.path">
            <NuxtLink :to="child.path">{{ child.title }}</NuxtLink>
          </li>
        </ul>
      </li>
    </ul>
  </nav>
</template>

Markdown Features

Syntax Highlighting

Configure in nuxt.config.ts:

export default defineNuxtConfig({
  content: {
    highlight: {
      theme: {
        default: "github-light",
        dark: "github-dark",
      },
      preload: ["typescript", "vue", "bash", "json"],
    },
  },
})

Use in markdown:

```typescript
interface User {
  name: string
  age: number
}
```

Custom Vue Components in Markdown

Use Vue components directly in markdown (MDC syntax):

# My Article

::Alert{type="info"}
This is an informational alert!
::

::CallToAction{title="Get Started" url="/docs"}
Learn more about Nuxt Content
::

Register components in components/content/ directory:

<!-- components/content/Alert.vue -->
<script setup lang="ts">
defineProps<{
  type?: "info" | "warning" | "error"
}>()
</script>

<template>
  <div :class="`alert alert-${type}`">
    <slot />
  </div>
</template>

TypeScript Support

Type your collections:

// types/content.ts
export interface BlogPost {
  title: string
  description: string
  date: string
  tags?: string[]
  author?: string
  image?: string
  draft: boolean
  path: string
  body: any
}

Use in components:

<script setup lang="ts">
import type { BlogPost } from "~/types/content"

const { data: posts } = await useAsyncData("posts", () =>
  queryCollection<BlogPost>("blog").all(),
)
</script>

Migration from v2

Key Changes

1. queryContent() → queryCollection(name)

   // v2
   queryContent("/blog").find()
   
   // v3
   queryCollection("blog").all()
   

2. Collections must be defined in content.config.ts

3. Components removed:

   • ❌ <ContentDoc> - use ContentRenderer
   • ❌ <ContentList> - query manually with queryCollection
   • ❌ <ContentNavigation> - use queryCollectionNavigation
   • ❌ <ContentQuery> - use queryCollection

4. New query methods:

   • .all() instead of .find()
   • .first() instead of .findOne()
   • .where() with SQL operators
   • .order() instead of .sort()

5. SQL-backed storage - faster queries for large datasets

Best Practices

1. Define collections - Always create content.config.ts with schemas
2. Use TypeScript - Type your collections for better DX
3. Cache queries - Use useAsyncData with proper keys
4. Server-side queries - Query on server for API routes
5. Index for performance - Consider indexing frequently queried fields
6. Validate frontmatter - Use Zod schemas in collection definitions
7. Handle 404s - Always check if content exists and throw errors
8. Use path() - More efficient than where() for path filtering
9. Select fields - Use .select() to reduce payload size
10. Pagination - Implement for large collections
