Server Components and the Return to HTML's Roots

Why Return to HTML?

The early web was HTML’s domain. Every page was a complete document. No JavaScript, no AJAX, no SPAs.

But the design wisdom from that era was forgotten.

Advantages of Server-Side Rendering

1. SEO-friendly — Search engines crawl complete HTML directly
2. Fast first paint — No waiting for JS execution
3. Progressive enhancement — Pages work even if JS fails
4. Zero JS — Pure static pages,极致性能

Astro’s Implementation

Astro uses “Islands Architecture”:

┌─────────────────────────────────────┐
│     Static HTML (Server Rendered)   │
│  ┌─────┐     ┌─────┐     ┌─────┐   │
│  │  JS │     │  JS │     │  JS │   │
│  │Island│    │Island│    │Island│   │
│  └─────┘     └─────┘     └─────┘   │
└─────────────────────────────────────┘

Only interactive parts load JS — everything else is pure HTML.

Conclusion

Modern frameworks are re-learning the wisdom of the early web.

Server-side rendering + progressive enhancement = optimal user experience
