Nuxt Content v3

Status: Production Ready Last Updated: 2025-01-10 Dependencies: None Latest Versions: @nuxt/content@^3.0.0, nuxt-studio@^0.1.0-alpha, zod@^4.1.12, valibot@^0.42.0, better-sqlite3@^11.0.0

---

Overview

Nuxt Content v3 is a powerful Git-based CMS for Nuxt projects that manages content through Markdown, YAML, JSON, and CSV files. It transforms content files into structured data with type-safe queries, automatic validation, and SQL-based storage for optimal performance.

What's New in v3

Major Improvements:

• Content Collections: Structured data organization with type-safe queries, automatic validation, and advanced query builder
• SQL-Based Storage: Production uses SQL (vs. large bundle sizes in v2) for optimized queries and universal compatibility (server/serverless/edge/static)
• Full TypeScript Integration: Automatic types for all collections and APIs
• Enhanced Performance: Ultra-fast data retrieval with adapter-based SQL system
• Nuxt Studio Integration: Self-hosted content editing in production with GitHub sync

When to Use This Skill

Use this skill when:

• Building blogs, documentation sites, or content-heavy applications
• Managing content with Markdown, YAML, JSON, or CSV files
• Implementing Git-based content workflows
• Creating type-safe content queries
• Deploying to Cloudflare (Pages/Workers) or Vercel
• Setting up production content editing with Nuxt Studio
• Building searchable content with full-text search
• Creating navigation systems from content structure

---

Quick Start (10 Minutes)

1. Install Nuxt Content

# Bun (recommended)
bun add @nuxt/content better-sqlite3

# npm
npm install @nuxt/content better-sqlite3

# pnpm
pnpm add @nuxt/content better-sqlite3

Why this matters:

• @nuxt/content

  is the core CMS module

• better-sqlite3

  provides SQL storage for optimal performance
• Zero configuration required for basic usage

2. Register Module

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@nuxt/content']
})

CRITICAL:

• Module must be added to

  modules

  array (not

  buildModules

  )
• No additional configuration needed for basic setup

3. Create First Collection

// content.config.ts
import { defineContentConfig, defineCollection } from '@nuxt/content'
import { z } from 'zod'

export default defineContentConfig({
  collections: {
    content: defineCollection({
      type: 'page',
      source: '**/*.md',
      schema: z.object({
        tags: z.array(z.string()).optional(),
        date: z.date().optional()
      })
    })
  }
})

Create content file:

<!-- content/index.md -->
---
title: Hello World
description: My first Nuxt Content page
tags: ['nuxt', 'content']
---

# Welcome to Nuxt Content v3

This is my first content-driven site!

4. Query and Render Content

<!-- pages/[...slug].vue -->
<script setup>
const route = useRoute()
const { data: page } = await useAsyncData(route.path, () =>
  queryCollection('content').path(route.path).first()
)
</script>

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

See Full Template:

templates/blog-collection-setup.ts

---

Critical Rules

Always Do

1. Define Collections in

   content.config.ts

   before querying
2. Use ISO 8601 Date Format:

   2024-01-15

   or

   2024-01-15T10:30:00Z

3. Restart Dev Server after changing

   content.config.ts

4. Use

   .only()

   to select specific fields (performance)
5. Place MDC Components in

   components/content/

   directory
6. Use Zero-Padded Prefixes for numeric sorting:

   01-

   ,

   02-

7. Install Database Connector:

   better-sqlite3

   required
8. Specify Language in code blocks for syntax highlighting
9. Use

   <!--more-->

   in content to separate excerpts
10. D1 Binding Must Be "DB" (case-sensitive) on Cloudflare

Never Do

1. Don't Query Before Defining Collection in

   content.config.ts

2. Don't Use Non-ISO Date Formats (e.g., "January 15, 2024")
3. Don't Forget to Restart dev server after config changes
4. Don't Query All Fields when you only need some (use

   .only()

   )
5. Don't Place Components outside

   components/content/

6. Don't Use Single-Digit Prefixes (use

   01-

   not

   1-

   )
7. Don't Skip Database Connector installation
8. Don't Forget Language in code fences
9. Don't Expect Excerpts without

   <!--more-->

   divider
10. Don't Use Different Binding Names for D1 (must be "DB")

Content Collections

Defining Collections

Collections organize related content with shared configuration:

// content.config.ts
import { defineCollection, defineContentConfig } from '@nuxt/content'
import { z } from 'zod'

export default defineContentConfig({
  collections: {
    blog: defineCollection({
      type: 'page',
      source: 'blog/**/*.md',
      schema: z.object({
        title: z.string(),
        date: z.date(),
        tags: z.array(z.string()).default([])
      })
    }),

    authors: defineCollection({
      type: 'data',
      source: 'authors/*.yml',
      schema: z.object({
        name: z.string(),
        bio: z.string()
      })
    })
  }
})

---

Collection Types

Page Type (

type: 'page'

)

Use for: Content that maps to URLs

Features:

• Auto-generates paths from file structure
• Built-in fields:

  path

  ,

  title

  ,

  description

  ,

  body

  ,

  navigation

• Perfect for: blogs, docs, marketing pages

Path Mapping:

content/index.md        → /
content/about.md        → /about
content/blog/hello.md   → /blog/hello

Data Type (

type: 'data'

)

Use for: Structured data without URLs

Features:

• Complete schema control
• No automatic path generation
• Perfect for: authors, products, configs

---

Schema Validation

With Zod v4 (Recommended)

bun add -D zod@^4.1.12
# or: npm install -D zod@^4.1.12

import { z } from 'zod'

schema: z.object({
  title: z.string(),
  date: z.date(),
  published: z.boolean().default(false),
  tags: z.array(z.string()).optional(),
  category: z.enum(['news', 'tutorial', 'update'])
})

With Valibot (Alternative)

bun add -D valibot@^0.42.0
# or: npm install -D valibot@^0.42.0

import * as v from 'valibot'

schema: v.object({
  title: v.string(),
  date: v.date(),
  published: v.boolean(false),
  tags: v.optional(v.array(v.string()))
})

---

Querying Content

Basic Queries

// Get all posts
const posts = await queryCollection('blog').all()

// Get single post by path
const post = await queryCollection('blog').path('/blog/hello').first()

// Get post by ID
const post = await queryCollection('blog').where('_id', '=', 'hello').first()

---

Field Selection

// Select specific fields (performance optimization)
const posts = await queryCollection('blog')
  .only(['title', 'description', 'date', 'path'])
  .all()

// Exclude fields
const posts = await queryCollection('blog')
  .without(['body'])
  .all()

---

Where Conditions

// Single condition
const posts = await queryCollection('blog')
  .where('published', '=', true)
  .all()

// Multiple conditions
const posts = await queryCollection('blog')
  .where('published', '=', true)
  .where('category', '=', 'tutorial')
  .all()

// Operators: =, !=, <, <=, >, >=, in, not-in, like
const recent = await queryCollection('blog')
  .where('date', '>', new Date('2024-01-01'))
  .all()

const tagged = await queryCollection('blog')
  .where('tags', 'in', ['nuxt', 'vue'])
  .all()

---

Ordering and Pagination

// Sort by field
const posts = await queryCollection('blog')
  .sort('date', 'DESC')
  .all()

// Pagination
const posts = await queryCollection('blog')
  .sort('date', 'DESC')
  .limit(10)
  .offset(0)
  .all()

---

Counting

// Count results
const total = await queryCollection('blog')
  .where('published', '=', true)
  .count()

---

Server-Side Queries

// server/api/posts.get.ts
export default defineEventHandler(async (event) => {
  const posts = await queryCollection('blog')
    .where('published', '=', true)
    .sort('date', 'DESC')
    .all()

  return { posts }
})

---

Navigation

Auto-generate navigation tree from content structure:

const navigation = await queryCollectionNavigation('blog').all()

Returns hierarchical structure:

[
  {
    title: 'Getting Started',
    path: '/docs/getting-started',
    children: [{ title: 'Installation', path: '/docs/getting-started/installation' }]
  }
]

Advanced patterns (filters, ordering, custom structures): See

references/collection-examples.md

---

MDC Syntax (Markdown Components)

Basic Component Syntax

<!-- Default slot -->
::my-alert
This is an alert message
::

<!-- Named slots -->
::my-card
#title
Card Title
#default
Card content here
::

Component:

<!-- components/content/MyAlert.vue -->
<template>
  <div class="alert">
    <slot />
  </div>
</template>

---

Props

::my-button{href="/docs" type="primary"}
Click me
::

Component:

<!-- components/content/MyButton.vue -->
<script setup>
defineProps<{
  href: string
  type: 'primary' | 'secondary'
}>()
</script>

---

Full-Text Search

// Search across all content
const results = await queryCollectionSearchSections('blog', 'nuxt content')
  .where('published', '=', true)
  .all()

Returns:

[
  {
    id: 'hello',
    path: '/blog/hello',
    title: 'Hello World',
    content: '...matching text...'
  }
]

---

Deployment

Cloudflare Pages + D1

bun add -D @nuxthub/core
bunx wrangler d1 create nuxt-content
bun run build && bunx wrangler pages deploy dist

wrangler.toml:

[[d1_databases]]
binding = "DB"  # Must be exactly "DB" (case-sensitive)
database_name = "nuxt-content"
database_id = "your-database-id"

CRITICAL: D1 binding MUST be named

DB

(case-sensitive).

See:

references/deployment-checklists.md

for complete Cloudflare deployment guide with troubleshooting.

---

Vercel

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@nuxt/content'],
  routeRules: {
    '/blog/**': { prerender: true }
  }
})

vercel deploy

See:

references/deployment-checklists.md

for complete Vercel configuration and prerender strategy.

---

Nuxt Studio Integration

Enable Studio

bun add -D nuxt-studio@alpha
# or: npm install -D nuxt-studio@alpha

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@nuxt/content', 'nuxt-studio'],
  
  studio: {
    enabled: true,
    gitInfo: {
      name: 'your-name',
      email: 'your-email@example.com'
    }
  }
})

OAuth Setup

1. Create GitHub OAuth App
2. Set Authorization callback URL:

   https://yourdomain.com/api/__studio/oauth/callback

3. Add client ID and secret to environment variables

CRITICAL: Callback URL must match production domain exactly (including

https://

).

Top 5 Critical Issues

Issue #1: Collection Not Found

Error:

Collection 'xyz' not found

Solution: Define collection in

content.config.ts

and restart dev server

rm -rf .nuxt && bun dev

---

Issue #2: Date Validation Failure

Error:

Validation error: Expected date, received string

Solution: Use ISO 8601 format:

---
date: 2024-01-15  # ✅ Correct
# NOT: "January 15, 2024"  # ❌ Wrong
---

---

Issue #3: D1 Binding Not Found (Cloudflare)

Error:

DB is not defined

Solution: D1 binding name must be exactly

DB

(case-sensitive) in Cloudflare dashboard.
