Getting Started with MDX

MDX is a powerful format that lets you write JSX (React components) inside Markdown documents. It's the perfect tool for technical blogs, documentation, and interactive content.

What is MDX?

MDX = Markdown + JSX

Think of it as Markdown on steroids. You get all the simplicity of Markdown for writing content, but you can also embed React components to add interactivity.

Why MDX? It allows you to create rich, interactive documentation and blog posts without sacrificing the ease of writing in Markdown.

Basic Markdown Syntax

All standard Markdown works in MDX:

Headings

# H1 Heading

## H2 Heading

### H3 Heading

Text Formatting

You can use bold, italic, ~~strikethrough~~, and inline code.

Lists

Unordered lists:

Item one
Item two
Item three

Ordered lists:

First item
Second item
Third item

Code Blocks

function greet(name) {
  console.log(`Hello, ${name}!`);
}

greet('World');

interface User {
  name: string;
  age: number;
}

const user: User = {
  name: 'John',
  age: 30,
};

The Power of Components

This is where MDX shines! You can embed React components directly in your content.

Callouts

This is a success callout! Perfect for highlighting positive outcomes or completed steps.

Warning callouts grab attention for important information that readers shouldn't miss.

Error callouts help readers avoid common mistakes or pitfalls.

Tables

MDX supports GitHub-flavored Markdown tables:

Feature	Markdown	MDX
Headings	✅	✅
Lists	✅	✅
Code blocks	✅	✅
React components	❌	✅
Interactivity	❌	✅

Writing Tips

1. Keep It Simple

Start with Markdown. Only add components when they truly enhance the content.

2. Use Callouts Strategically

Callouts should highlight important information, not replace regular paragraphs.

3. Code Examples

Always include code examples for technical content:

// Good: Clear, commented code
function Button({ text }) {
  return <button className="btn">{text}</button>;
}

4. Break Up Content

Use headings, lists, and visual elements to make content scannable.

Best Practices

Write for humans first - Clear, conversational prose
Add interactivity - Use components to enhance understanding
Show, don't tell - Include code examples and demos
Stay organized - Use consistent heading hierarchy
Test your content - Read it aloud, check all links

Next Steps

Ready to start writing with MDX? Here's what to do:

Create a new .mdx file in content/blog/
Add frontmatter with title, excerpt, and tags
Write your content using Markdown
Add components where they add value
Preview and publish!

Pro Tip: Keep a "components library" document where you test different component combinations before using them in posts.
