React Forms with React Hook Form

bookOptimizing 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 FormProvider and useFormContext;
  • 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.
