Optimizing Form Performance
To keep large forms responsive with React Hook Form, focus on minimizing unnecessary re-renders. React Hook Form achieves high performance by using uncontrolled inputs, allowing the DOM to manage field values instead of storing them in React state.
To keep forms scalable and fast:
- Use uncontrolled components whenever possible;
- Use watch only for fields you truly need to observe, since it subscribes to value changes;
- Split large forms into smaller components using
FormProvideranduseFormContext; - Memoize expensive child components with
React.memo; - When performance is critical, prefer native inputs over heavily controlled UI library components.
Following these principles helps ensure forms remain responsive as they grow in size and complexity.
