🔹 Phase 3 – Configuring Astro for Handbook / Docs

3.1 Project Layout (Best Practice)

astro-handbook/
├── src/
│   ├── content/
│   │   └── handbook/
│   ├── layouts/
│   │   └── HandbookLayout.astro
│   ├── components/
│   └── pages/
├── public/
├── astro.config.mjs

3.2 Enable Content Collections

`src/content/config.ts`

import { defineCollection, z } from 'astro:content';

const handbook = defineCollection({
  schema: z.object({
    title: z.string(),
    order: z.number(),
    description: z.string().optional(),
  }),
});

export const collections = {
  handbook,
};

3.3 Example Handbook Chapter

`src/content/handbook/01-introduction.md`

---
title: "Introduction to Astro"
order: 1
description: "Overview of Astro and its philosophy"
---

Astro is designed for content-first websites.

## Why Astro?
- Performance
- Simplicity
- Markdown-first

Sort pages by order field:

const pages = (await getCollection("handbook"))
  .sort((a, b) => a.data.order - b.data.order);

3.5 Handbook Layout Example

`src/layouts/HandbookLayout.astro`

---
const { title } = Astro.props;
---

<html>
  <head>
    <title>{title}</title>
  </head>
  <body>
    <aside>
      <slot name="sidebar" />
    </aside>
    <main>
      <slot />
    </main>
  </body>
</html>

🔹 Phase 4 – Development Workflow

4.1 Add Markdown Enhancements

pnpm add @astrojs/markdown-remark remark-gfm rehype-slug

Update astro.config.mjs:

import { defineConfig } from 'astro/config';

export default defineConfig({
  markdown: {
    remarkPlugins: ['remark-gfm'],
    rehypePlugins: ['rehype-slug'],
  },
});

4.2 Syntax Highlighting

pnpm add shiki

Astro auto-detects Shiki for code blocks.

  const root = document.documentElement;

  // Load saved theme
  if (localStorage.theme === 'dark' || (!localStorage.theme && window.matchMedia('(prefers-color-scheme: dark)').matches)) {
    root.classList.add('dark');
  }

  btn.addEventListener('click', () => {
    root.classList.toggle('dark');
    localStorage.theme = root.classList.contains('dark') ? 'dark' : 'light';

☁️ Netlify

Connect repo
Build command: pnpm build
Publish: dist

1️⃣ GitHub Repo Structure

Your repository should already contain the AstroBook setup:

astrobook-demo/
├── src/
│   ├── content/          # Chapters (v1, v2) & glossary
│   ├── components/
│   ├── layouts/
│   ├── pages/
│   └── styles/
├── public/
├── astro.config.mjs
├── package.json
├── tailwind.config.js
└── postcss.config.cjs

Content files: Update/add Markdown files under src/content/book/v1 or v2.
Glossary: src/content/glossary/
Assets: Images, favicons, PDFs → public/

2️⃣ Update / Add Content

Create new chapters:

src/content/book/v1/03-configuration.md
src/content/book/v2/03-configuration.md

Add glossary entries:

src/content/glossary/mermaid.md

Add diagrams / callouts in Markdown using the <Mermaid /> component or blockquotes.

3️⃣ Commit & Push Changes

git add .
git commit -m "Add new chapter and glossary entries"
git push origin main

Each push triggers Netlify to rebuild the site automatically.
Your three-pane layout, TOC, and PWA remain functional without additional work.

4️⃣ Netlify Build Settings (One-Time)

When connecting your GitHub repo to Netlify:

Setting	Value
Build command	`pnpm build`
Publish directory	`dist`
Node version	20 (matches Astro config)
Install command	`pnpm install`

Netlify detects astro.config.mjs automatically.

5️⃣ Versioned Documentation

Netlify will serve v1 and v2 automatically based on folder structure.
If you add new versions:

src/content/book/v3/

Update sidebar component (already dynamic) → v3 will appear automatically.

6️⃣ Offline / PWA Updates

The PWA configuration in astro.config.mjs ensures offline mode works immediately.
After Netlify rebuilds, users’ browsers automatically fetch updated service worker assets on next visit.

7️⃣ Recommended Workflow Summary

Edit / add content locally in src/content/
Test locally:

pnpm dev

Build & preview if needed:

pnpm build
pnpm preview

Commit & push to GitHub:

git add .
git commit -m "Update handbook"
git push

Netlify rebuilds and serves updated site automatically.
