5 Ways To Use React Hook Form Debounce

Quick Links :

When building complex web applications, handling user input efficiently is crucial. One way to achieve this is by implementing debouncing techniques. Debouncing ensures that your application doesn't overwhelm the server with frequent requests, especially when dealing with forms that need to validate data in real-time. React Hook Form is a popular library used for managing forms in React applications, and it offers a debouncing feature to handle this issue.

What is Debouncing?

Debouncing is a programming technique used to limit the rate at which a function can be called. It's commonly used in scenarios where you want to delay the execution of a function until a specified amount of time has passed since the last time it was invoked. This technique is particularly useful when dealing with events that occur rapidly, such as keypress events in a text input field.

Understanding React Hook Form

React Hook Form is a library that simplifies the process of managing forms in React applications. It provides a set of hooks and utilities that make it easy to handle form data, validation, and submission. The library is highly customizable and offers features like debouncing, which can be used to delay the execution of certain functions until a specified amount of time has passed.

5 Ways to Use React Hook Form Debounce

1. Debouncing Form Submission

Debouncing form submission is a great way to prevent multiple submissions from happening in quick succession. This can be achieved by wrapping the form submission handler in a debounced function.

import { useForm } from 'react-hook-form';
import { debounce } from 'lodash';

const DebouncedForm = () => {
  const { register, handleSubmit } = useForm();
  const debouncedSubmit = debounce(handleSubmit, 500);

  return (
    

      {/* form fields */}
    
  );
};

2. Debouncing Validation

Debouncing validation is useful when you want to delay the execution of validation rules until the user has stopped typing. This can be achieved by using the debounce option provided by React Hook Form.

import { useForm } from 'react-hook-form';

const DebouncedValidation = () => {
  const { register, handleSubmit } = useForm({
    mode: 'onChange',
    reValidateMode: 'onChange',
    debounce: {
      blur: 500,
    },
  });

  return (
    

      {/* form fields */}
    
  );
};

3. Debouncing API Calls

Debouncing API calls is useful when you want to delay the execution of API requests until the user has stopped typing. This can be achieved by wrapping the API call in a debounced function.

import { useForm } from 'react-hook-form';
import { debounce } from 'lodash';

const DebouncedAPI = () => {
  const { register, watch } = useForm();
  const debouncedAPI = debounce((value) => {
    // make API call
  }, 500);

  watch((value) => {
    debouncedAPI(value);
  });

  return (
    

      {/* form fields */}
    
  );
};

4. Debouncing Input Field Updates

Debouncing input field updates is useful when you want to delay the execution of input field updates until the user has stopped typing. This can be achieved by using the debounce option provided by React Hook Form.

import { useForm } from 'react-hook-form';

const DebouncedInput = () => {
  const { register, watch } = useForm({
    debounce: {
      onChange: 500,
    },
  });

  watch((value) => {
    // update input field
  });

  return (
    

      {/* form fields */}
    
  );
};

5. Debouncing Search Queries

Debouncing search queries is useful when you want to delay the execution of search queries until the user has stopped typing. This can be achieved by wrapping the search query in a debounced function.

import { useForm } from 'react-hook-form';
import { debounce } from 'lodash';

const DebouncedSearch = () => {
  const { register, watch } = useForm();
  const debouncedSearch = debounce((value) => {
    // make search query
  }, 500);

  watch((value) => {
    debouncedSearch(value);
  });

  return (
    

      {/* form fields */}
    
  );
};

By applying these debouncing techniques, you can significantly improve the performance and usability of your React applications that use forms.
