DRAFT: Optimize Search Parameter Performance#

Final Destination: docs/router/framework/react/how-to/optimize-search-param-performance.md Progressive Series Position: Advanced Level (Power User Patterns) - Guide #7 Depends On: setup-basic-search-params.md, navigate-with-search-params.md Status: Ready for implementation - performance patterns available

Performance Issues with Functional Updates#

Problem: Complex functional updates cause unnecessary re-renders.

// ❌ Wrong - complex computation in render
<Link search={(prev) => {
  // Expensive computation on every render
  const result = expensiveCalculation(prev)
  return { ...prev, computed: result }
}}>
  Update
</Link>

// ✅ Correct - memoize or use callback
const updateSearch = useCallback((prev) => {
  const result = expensiveCalculation(prev)
  return { ...prev, computed: result }
}, [])

<Link search={updateSearch}>Update</Link>

Navigation During Render#

Problem: Calling navigate during component render causes infinite loops.

function ProblematicComponent() {
  const navigate = useNavigate()

  // ❌ Wrong - navigate during render
  if (someCondition) {
    navigate({ search: { redirect: true } })
  }

  return <div>Content</div>
}

function FixedComponent() {
  const navigate = useNavigate()

  // ✅ Correct - navigate in effect
  useEffect(() => {
    if (someCondition) {
      navigate({ search: { redirect: true } })
    }
  }, [someCondition, navigate])

  return <div>Content</div>
}
