Web apps need speed. They need SEO.
SSR helps. Full hydration slows things down.
Use incremental hydration. Render HTML first. Load JS for specific parts only when needed.
Why this works:
- Faster Time to Interactive.
- Smaller JS bundles.
- Screen readers see content early.
How to do it:
- Set goals. Aim for First Contentful Paint under 1.5 seconds.
- Map interactive areas. Use data attributes to mark them.
- Build a dispatcher. Load JS when a user scrolls or clicks.
- Keep semantic HTML. Maintain ARIA labels.
Track your success:
- Measure FCP.
- Track TTI per widget.
- Watch for layout shifts.
Avoid these mistakes:
- Do not let server HTML and client state differ.
- Do not create too many hydration regions.
- Do not remove content during hydration.
