JSdev Astro Theme is an open-source, MIT-licensed Astro + TypeScript blog template with MDX and SEO support, built to publish fast, statically rendered content to any JAMstack host.
What is JSdev Astro Theme?
JSdev Astro Theme is a minimal blog starter built on the Astro framework with TypeScript and MDX. It takes Markdown or MDX blog posts as input and generates a static site with pages, tag archives, search, and RSS output. The theme is maintained by JSDev.Space and is the actual template behind that site, so it is production-tested and ready to deploy.
Key Features
- Astro-powered static rendering — the site builds to plain HTML with no runtime JavaScript overhead, which keeps pages fast and scores well on performance checks.
- MDX support — blog posts live in
src/content/blog/as.mdxfiles, so you can embed React components inside Markdown content. - Built-in search — a fast, keyboard-accessible search with fuzzy matching that opens with Cmd/Ctrl+K and filters all posts live.
- SEO ready — includes meta tags, OpenGraph support, robots.txt, and an RSS feed out of the box.
- Dark/light theme — a clean minimal design with a toggleable dark mode, plus mobile-first responsive layout.
- Organized project structure — source files are separated into
app/,components/,content/,pages/, andshared/directories for easy maintenance. - Built-in pagination — static pagination for the home page at
/blog/and tag pages at/blog/tags/[tag]/, with automatic numbered page generation.
Who should use JSdev Astro Theme?
- Technical bloggers and developers — write posts in MDX and deploy to Netlify, Vercel, or Cloudflare Pages with minimal configuration.
- Indie writers and newsletter authors — publish a clean, typography-focused blog without managing a database or CMS.
- Open-source maintainers — use it for a project blog or changelog, taking advantage of the MIT license and zero cost.

How does JSdev Astro Theme work?
The template uses Astro's static renderer. You run npm install and then npm dev for a local development server. Write your posts as MDX files under src/content/blog/, run npm build to generate a static dist/ directory, and deploy that folder to your host. The build process automatically generates index pages, tag archives, and RSS.
