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

2019: Use the 'useCallback' react hook

After trying many different approaches, I found using useCallback to be the simplest and most efficient at solving the multiple calls problem of using debounce within an onChange event.

As per the Hooks API documentation,

useCallback returns a memorized version of the callback that only changes if one of the dependencies has changed.

Passing an empty array as a dependency makes sure the callback is called only once. Here's a simple implementation :

import React, { useCallback } from "react";
import { debounce } from "lodash";

const handler = useCallback(debounce(someFunction, 2000), []);

const onChange = (event) => {
    // perform any event related action here

    handler();
 };

Hope this helps!
