How to use the useDebounce hook for debouncing API requests in Next.js



Image not found!!

To use the useDebounce hook for debouncing API requests in a Next.js application, you'll need to follow these steps:

  1. Install the use-debounce library:
bash
npm install use-debounce
  1. Create a custom hook that uses the useDebounce hook and handles API requests:
jsx
// hooks/useDebouncedApiRequest.js
import { useState, useEffect } from 'react';
import useDebounce from 'use-debounce';

const useDebouncedApiRequest = (initialValue, delay) => {
  const [value, setValue] = useState(initialValue);
  const [debouncedValue] = useDebounce(value, delay);
  const [data, setData] = useState(null);
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchData = async () => {
      setLoading(true);
      setError(null);

      try {
        // Your API request logic here
        const response = await fetch(`https://api.example.com/search?q=${debouncedValue}`);
        const result = await response.json();
        setData(result);
      } catch (error) {
        setError(error);
      } finally {
        setLoading(false);
      }
    };

    // Execute the API request when the debounced value changes
    if (debouncedValue) {
      fetchData();
    }
  }, [debouncedValue]);

  return {
    value,
    setValue,
    data,
    loading,
    error,
  };
};

export default useDebouncedApiRequest;

In this example, the custom hook useDebouncedApiRequest takes an initial value and a delay as parameters. It uses the useDebounce hook to create a debounced value (debouncedValue). The hook also manages the API request state, including the data, loading state, and error.

  1. Use the custom hook in your Next.js component:
jsx
// pages/index.js
import { useState } from 'react';
import useDebouncedApiRequest from '../hooks/useDebouncedApiRequest';

const Home = () => {
  const [searchTerm, setSearchTerm] = useState('');
  const { value, setValue, data, loading, error } = useDebouncedApiRequest(searchTerm, 500);

  const handleInputChange = (e) => {
    setSearchTerm(e.target.value);
    setValue(e.target.value);
  };

  return (
    <div>
      <input type="text" value={searchTerm} onChange={handleInputChange} />
      {loading && <p>Loading...</p>}
      {error && <p>Error: {error.message}</p>}
      {data && (
        <ul>
          {data.results.map((result) => (
            <li key={result.id}>{result.name}</li>
          ))}
        </ul>
      )}
    </div>
  );
};

export default Home;

In this example, the Home component uses the useDebouncedApiRequest hook to handle the API request. It includes an input field for users to enter search terms, and the API request is triggered after a debounce period (500 milliseconds in this case). The loading state and error handling are also included in the component. Adjust the API request logic and UI rendering according to your specific requirements.
