DevTut is a modern, high-performance reference portal featuring example-based programming tutorials for solid developers. It covers 45+ programming topics and 3,500+ tutorials compiled for speed and modern search engine optimization (SEO).

This portal has been fully migrated from a legacy VuePress architecture to a state-of-the-art Astro 6 and Starlight documentation engine.

• Core Documentation Engine: Astro v6 (ESM)
• Theme & Navigation: Starlight v0.39
• Client-Side Framework: Vue 3.5 (for interactive search widgets)
• Search Integration: Pagefind (high-performance serverless search indexer)
• Styling & Theming: Custom Emerald Green Design System (#42b983)

Install project dependencies using Yarn:

yarn install

Start the local development server (page compiles on demand for instant startup):

yarn dev

Open http://localhost:4321/ in your browser.

Because this repository contains over 3,500 pages, compiling all languages can take longer during active development. You can isolate your workspace to focus only on a single language (e.g., JavaScript):

• Switch to Isolated Mode (JavaScript only):

  node migrate.cjs && node isolate-javascript.cjs

  (Then run yarn dev for sub-second, instant hot reloads!)

• Switch back to Full Repository Mode:

  node migrate.cjs

Build highly optimized static assets (compiles static pages, Pagefind search indexes, and SEO sitemaps):

yarn docs:build

To build and publish the latest version of the site directly to GitHub Pages, run the automated script:

./deploy.sh
