Static Site Generation

Framework Evaluation Criteria

When evaluating SSG frameworks, prioritize:

1. TypeScript support: First-class, not bolted-on
2. MDX integration: Built-in or official plugin
3. GitHub Pages compatibility: Base path support, static output
4. Content collections: Type-safe content with schema validation
5. Build performance: Fast rebuilds for iteration
6. DX: Good error messages, debugging tools

Framework Comparison for Knowledge Base

Astro (Recommended for content-first sites)

• Pros: Best MDX support, fast builds, content collections, multi-framework
• Cons: Newer ecosystem, fewer community plugins
• Best for: Documentation, knowledge bases, content-heavy sites

Next.js with Static Export

• Pros: Huge ecosystem, familiar to React devs, mature tooling
• Cons: Overkill for simple sites, larger bundles, requires explicit static config
• Best for: Apps needing both static and dynamic capabilities

VitePress

• Pros: Extremely fast, excellent docs focus, simple
• Cons: Vue-specific, less flexible for complex needs
• Best for: Pure documentation sites with minimal custom needs

Avoid: Gatsby (complex, slow builds, declining momentum)

GitHub Pages Configuration

Critical Settings

Base Path for Subpath Deployment:

// Required if deploying to github.io/repo-name/
export default defineConfig({
  site: 'https://username.github.io',
  base: '/repo-name/',  // Must include trailing slash
});

Output Directory:

• Astro: dist/ (default)
• Next.js: out/ (with output: 'export')
• VitePress: .vitepress/dist/

404 Handling:

• Create 404.html in output directory
• For SPAs: All routes → 404.html (GitHub Pages limitation)

Deployment Pattern

Using GitHub Actions (Recommended):

permissions:
  contents: read
  pages: write
  id-token: write

jobs:
  deploy:
    steps:
      - uses: actions/checkout@v4
      - run: npm ci
      - run: npm run build
      - uses: actions/upload-pages-artifact@v3
        with:
          path: ./dist
      - uses: actions/deploy-pages@v4

Repository Settings:

• Pages → Source: "GitHub Actions"
• Branch deployment not needed with Actions

Build Optimization Checklist

Before marking build complete:

• [ ] TypeScript strict mode enabled
• [ ] Base path configured correctly
• [ ] All routes generate static HTML
• [ ] Assets use correct paths (relative to base)
• [ ] 404 page exists
• [ ] Build succeeds with zero errors
• [ ] Deployment workflow tested

Content Collections Pattern

Define schemas for type-safe content:

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

const docs = defineCollection({
  schema: z.object({
    title: z.string(),
    description: z.string(),
    date: z.date(),
    draft: z.boolean().default(false),
  }),
});

export const collections = { docs };

Benefits: Type safety, validation at build time, autocomplete in editor.

Common Pitfalls

Incorrect base path:

• Symptom: Routes work locally, 404 in production
• Fix: Ensure base matches repo name, includes trailing slash

Mixed path types:

• Symptom: Some assets load, others don't
• Fix: Use framework's path helpers consistently

Large bundle size:

• Symptom: Slow initial load
• Fix: Enable code splitting, lazy load heavy components

Missing TypeScript config:

• Symptom: Type errors not caught during build
• Fix: Enable strict mode, include all source files

Decision Template

When choosing framework, document in CLAUDE.md:

## Framework Decision: [Name]

**Chosen:** [Framework]
**Rationale:** [Why - 2-3 key reasons]
**Alternatives considered:** [What else, why not]
**Trade-offs:** [What we gain vs. lose]

Quick Start Validation

After framework initialization:

1. Run build → Should succeed with zero errors
2. Check output directory → HTML files present
3. Test locally → npx serve dist → All routes work
4. Deploy to GitHub Pages → All routes work with base path
5. Check console → No 404s on assets
