Building a Modern Blog with Next.js and MDX
In this tutorial, we'll explore how to build a modern, performant blog using Next.js 16 and MDX. This setup gives you the best of both worlds: the simplicity of Markdown with the power of React components.
Why MDX?
MDX allows you to:
- Write content in Markdown
- Import and use React components
- Create interactive documentation
- Maintain type safety with TypeScript
Project Structure
Here's the ideal structure for your blog:
/content/posts # MDX blog posts
/lib/posts.ts # Server-side utilities
/app/blog # Blog routes
/components # Reusable components
Features
1. Frontmatter Support
Every blog post includes metadata:
---
title: "Your Post Title"
date: "2025-11-24"
description: "Post description"
tags: ["tag1", "tag2"]
---
2. Automatic Reading Time
Reading time is calculated automatically using the reading-time package.
3. SEO Optimization
All posts include:
- Meta tags
- Open Graph images
- Twitter Cards
- Canonical URLs
Code Examples
TypeScript Example
interface Post {
slug: string
metadata: PostMetadata
content: string
}
export function getAllPosts(): Post[] {
// Implementation
}
Styling with Tailwind
<div className="prose dark:prose-invert max-w-none">
{content}
</div>
Deployment
Deploy to Vercel with zero configuration:
- Push to GitHub
- Import to Vercel
- Deploy automatically
Conclusion
This setup provides a solid foundation for a modern blog with excellent performance and developer experience.
Happy blogging! 🚀
