你必须使用useCallback，正如在这篇博客中提到的:

https://www.freecodecamp.org/news/debounce-and-throttle-in-react-with-hooks/

import React, { useCallback } from 'react';
import debounce from 'debounce'; // or another package

function App() {
    ...
    const debouncedSave = useCallback(
        debounce(x => foo(x), 1000),
        [], // will be created only once initially
    );
    ...
}

FYI

这是另一个PoC实现:

没有任何库(例如lodash)用于debound 使用React Hooks API

我希望它能帮助你:)

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<string>('');
  const [timer, setTimer] = useState<NodeJS.Timer | undefined>();

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

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

  return (
    <input
      type={inputType || 'text'}
      className="form-control"
      placeholder={placeholder}
      value={query}
      onChange={handleOnChange}
    />
  );
}

/**
 * Returns a function with the same signature of input `callback` (but without an output) that if called, smartly
 * executes the `callback` in a debounced way.<br>
 * There is no `delay` (to execute the `callback`) in the self-delayed tries (try = calling debounced callback). It
 * will defer **only** subsequent tries (that are earlier than a minimum timeout (`delay` ms) after the latest
 * execution). It also **cancels stale tries** (that have been obsoleted because of creation of newer tries during the
 * same timeout).<br>
 * The timeout won't be expanded! So **the subsequent execution won't be deferred more than `delay`**, at all.
 * @param {Function} callback
 * @param {number} [delay=167] Defaults to `167` that is equal to "10 frames at 60 Hz" (`10 * (1000 / 60) ~= 167 ms`)
 * @return {Function}
 */
export function smartDebounce (callback, delay = 167) {
  let minNextExecTime = 0
  let timeoutId

  function debounced (...args) {
    const now = new Date().getTime()
    if (now > minNextExecTime) { // execute immediately
      minNextExecTime = now + delay // there would be at least `delay` ms between ...
      callback.apply(this, args) // ... two consecutive executions
      return
    }
    // schedule the execution:
    clearTimeout(timeoutId) // unset possible previous scheduling
    timeoutId = setTimeout( // set new scheduling
      () => {
        minNextExecTime = now + delay // there would be at least `delay` ms between ...
        callback.apply(this, args) // ... two consecutive executions
      },
      minNextExecTime - now, // 0 <= timeout <= `delay` ... (`minNextExecTime` <= `now` + `delay`)
    )
  }

  debounced.clear = clearTimeout.bind(null, timeoutId)

  return debounced
}

/**
 * Like React's `useCallback`, but will {@link smartDebounce smartly debounce} future executions.
 * @param {Function} callback
 * @param {[]} deps
 * @param {number} [delay=167] - Defaults to `167` that is equal to "10 frames at 60 Hz" (`10 * (1000 / 60) ~= 167 ms`)
 */
export const useDebounced = (callback, deps, delay = 167) =>
  useMemo(() => smartDebounce(callback, delay), [...deps, delay])

这里已经有很多好的信息了，但为了简洁。这对我很有用……

import React, {Component} from 'react';
import _ from 'lodash';

class MyComponent extends Component{
      constructor(props){
        super(props);
        this.handleChange = _.debounce(this.handleChange.bind(this),700);
      }; 

看点:

import {useState} from "react";

const useDebounce = ({defaultTimeout = 250, defaultIdentifier = 'default'} = {}) => {

    const [identifiers, setIdentifiers] = useState({[defaultIdentifier]: null});

    return ({fn = null, identifier = defaultIdentifier, timeout = defaultTimeout} = {}) => {
        if (identifiers.hasOwnProperty(identifier)) clearTimeout(identifiers[identifier]);
        setIdentifiers({...identifiers, [identifier]: setTimeout(fn, timeout)});
    };
};

export default useDebounce;

并在任何地方使用它(在同一个文件中使用标识符以防止并发)，例如:

const debounce = useDebounce();

const handlerA = () => {
    debounce({fn: () => console.log('after 2000ms of last call with identifier A'), identifier: 'A', timeout: 2000});
};

const handlerB = () => {
    debounce({fn: () => console.log('after 1500ms of last call with identifier B'), identifier: 'B', timeout: 1500});
};

你也可以使用自己编写的mixin，就像这样:

var DebounceMixin = {
  debounce: function(func, time, immediate) {
    var timeout = this.debouncedTimeout;
    if (!timeout) {
      if (immediate) func();
      this.debouncedTimeout = setTimeout(function() {
        if (!immediate) func();
        this.debouncedTimeout = void 0;
      }.bind(this), time);
    }
  }
};

然后像这样在你的组件中使用它:

var MyComponent = React.createClass({
  mixins: [DebounceMixin],
  handleClick: function(e) {
    this.debounce(function() {
      this.setState({
        buttonClicked: true
      });
    }.bind(this), 500, true);
  },
  render: function() {
    return (
      <button onClick={this.handleClick}></button>
    );
  }
});
