What I Can Do With Markdown in Nextjs

In Next.js, leveraging Markdown files for content management offers a flexible, efficient, and developer-friendly way to handle static content like blog posts, documentation, or any text-based content that benefits from being stored in a human-readable format. Here’s how you can utilize Markdown in Next.js:

1. Storing and Managing Content

Markdown files (

if you're using MDX) can be used to store your content in a structured format with simple markup. You can organize these files in your project's directory (e.g., a
directory) and use front matter to include metadata such as titles, authors, publication dates, and tags.

2. Parsing and Displaying Markdown Content

To display Markdown content in your Next.js application, you'll need to:

  • Read the Markdown files from the filesystem in the server-side environment (using
  • Parse the Markdown content and front matter, converting it into HTML or React components. Libraries such as
    , and
    are commonly used for parsing and handling Markdown in JavaScript.

3. Static Site Generation (SSG) with Markdown

Next.js excels at Static Site Generation. You can use

to read and parse Markdown files at build time, generating static pages for each piece of content. Combine this with
for dynamic routes (e.g., blog post slugs), and you have a powerful, SEO-friendly blogging platform or documentation site built with Next.js and Markdown.

4. Using MDX for Enhanced Markdown

MDX is an extension of Markdown that allows you to use JSX within your Markdown files. This means you can import and use React components directly in your Markdown, offering a rich interactive experience. To use MDX in Next.js, you might use the

plugin or other tools like
to integrate MDX support into your project.

5. Incremental Static Regeneration (ISR)

For content stored in Markdown that may update over time, Next.js's Incremental Static Regeneration feature allows you to regenerate static content on a per-page basis without needing to rebuild the entire site. This is particularly useful for content-driven sites where the Markdown files get updated frequently.

Example Workflow with Markdown in Next.js

  1. Install necessary libraries for parsing Markdown. For basic Markdown,

    for front matter and
    for Markdown to HTML conversion might suffice. For MDX,

  2. Read and parse Markdown files in


import fs from 'fs';
import path from 'path';
import matter from 'gray-matter';
import { remark } from 'remark';
import html from 'remark-html';

const postsDirectory = path.join(process.cwd(), 'posts');

export async function getStaticProps() {
  const fullPath = path.join(postsDirectory, 'my-post.md');
  const fileContents = fs.readFileSync(fullPath, 'utf8');

  // Use gray-matter to parse the post metadata section
  const matterResult = matter(fileContents);

  // Use remark to convert markdown into HTML string
  const processedContent = await remark().use(html).process(matterResult.content);
  const contentHtml = processedContent.toString();

  // Combine the data with the id
  return {
    props: {
      postData: {
  1. Render the HTML content in your React component, ensuring to dangerously set HTML since it’s generated content you trust:
export default function Post({ postData }) {
  return (
      <div dangerouslySetInnerHTML={{ __html: postData.contentHtml }} />

This workflow demonstrates the basics of integrating Markdown with Next.js for static content management. The combination of Next.js and Markdown is particularly powerful for blogs, documentation sites, and any scenario where content might be authored in a version-controlled, plain-text format.
