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:

  1. Incremental hydration (hydrate visible components first)
  2. Selective hydration for interactive components only
  3. Lazy hydration for below-the-fold content

This would significantly improve Core Web Vitals scores for Vue 2 SSR applications.
