Introduction

MDX lets you write blog posts in Markdown while embedding interactive components. Adding TypeScript ensures those components are type-safe. Together, they streamline content updates and prevent runtime errors.

1. Installing & Configuring MDX

Install the integration

npm install @astrojs/mdx

 2.	Enable in Astro config

// astro.config.mjs import mdx from ‘@astrojs/mdx’;

export default { integrations: [mdx()], };

⸻

Writing Your First MDX Post

Place posts under src/content/posts/hello.mdx:

title: “Hello MDX” date: “2025-05-17”

Welcome to MDX

This is regular Markdown.

⸻

Adding TypeScript to Components • Create typed components under src/components/:

// src/components/MyAlert.tsx interface Props { message: string } export default function MyAlert({ message }: Props) { return

{message}

; }

•	Import in MDX without losing type checks:

import MyAlert from ‘../components/MyAlert.tsx’;

⸻

Benefits for Your Workflow • Writer-Friendly: Markdown for non-technical contributors. • Developer Confidence: TypeScript catches mismatched props at build time. • Single Source: Content and components live in the same repo—no external CMS needed.

⸻

Takeaway

MDX plus TypeScript in Astro delivers a best-of-both-worlds solution: easy authoring and reliable, type-checked components. It’s ideal for blogs, documentation, or any content-driven site.
