Perform debounce in React.js

Question

How do you perform debounce in React.js?

I want to debounce the handleOnChange.

I tried with debounce(this.handleOnChange, 200) but it doesn\'t

Answer 1

FYI

Here is another PoC implementation:

• without any libraries (e.g. lodash) for debouncing
• using React Hooks API

I hope it helps :)

import React, { useState, useEffect, ChangeEvent } from 'react';

export default function DebouncedSearchBox({
  inputType,
  handleSearch,
  placeholder,
  debounceInterval,
}: {
  inputType?: string;
  handleSearch: (q: string) => void;
  placeholder: string;
  debounceInterval: number;
}) {
  const [query, setQuery] = useState('');
  const [timer, setTimer] = useState();

  useEffect(() => {
    if (timer) {
      clearTimeout(timer);
    }
    setTimer(setTimeout(() => {
      handleSearch(query);
    }, debounceInterval));
  }, [query]);

  const handleOnChange = (e: ChangeEvent): void => {
    setQuery(e.target.value);
  };

  return (
    
  );
}
