Why Next.js?
Next.js is a full-stack React framework that lets you build fast blogs through static site generation (SSG).
Key Advantages
- Static Builds: Fast loading with HTML generated at build time
- SEO Optimization: Easy SEO setup with the Metadata API
- MDX Support: Use React components inside Markdown
Project Setup
Start by creating a new project:
npx create-next-app@latest my-blog --typescript --tailwindDirectory Structure
my-blog/
├── content/
│ └── posts/ # MDX files
├── src/
│ ├── app/ # Pages
│ ├── components/ # Components
│ └── lib/ # Utilities
└── public/ # Static files
MDX Configuration
MDX lets you use React components inside Markdown.
import { compileMDX } from 'next-mdx-remote/rsc';
export async function compileMDXContent(source: string) {
const { content } = await compileMDX({
source,
options: {
mdxOptions: {
remarkPlugins: [remarkGfm],
rehypePlugins: [rehypeSlug, rehypePrettyCode],
},
},
});
return { content };
}💡
Using next-mdx-remote allows you to compile MDX in server components, resulting in great build performance.
Code Syntax Highlighting
With rehype-pretty-code and shiki, you can implement beautiful code highlighting:
function greet(name) {
// Greet if name exists
if (name) {
console.log(`Hello, ${name}!`);
}
return name;
}SEO Optimization
Using the Next.js Metadata API, you can configure metadata for each page.
export async function generateMetadata({ params }) {
const post = getPostBySlug(params.slug);
return {
title: post.title,
description: post.description,
openGraph: { ... },
};
}Conclusion
A blog built with Next.js and MDX is the ideal choice for developers. It's fast with static builds, easy to optimize for SEO, and convenient for writing posts in Markdown.
