Discussion: Improving SSR hydration performance for complex components
Author: fbwe425Created Sep 6, 2026Updated Sep 6, 2026
Description
Vue 2 SSR hydration can be slow for components with deep nesting and complex reactive data. This affects initial page load performance.
Observation
Components with 50+ reactive properties and deep child trees show 200-400ms hydration delays.
Suggestion
Consider:
- Incremental hydration (hydrate visible components first)
- Selective hydration for interactive components only
- Lazy hydration for below-the-fold content
This would significantly improve Core Web Vitals scores for Vue 2 SSR applications.
