I am trying to implement a search that makes a new query on each character change. After n milliseconds, I need to make a change to the object that stores some properties.
//user typing
const onInputChange = (e) => {
let searchInput = e.target.value;
useDebounce(
handleSearchPropsChange({
filter: {
searchInput,
dateRange: {
start,
end
}
}
}), 1000
);
}
The function I am using for the delayed call
import {debounce} from 'lodash';
import {useRef} from 'react';
export function useDebounce(callback = () => {}, time = 500) {
return useRef(debounce(callback, time)).current;
}
But I am getting the error:
Invalid hook call. Hooks can only be called inside of the body of a function component. This
could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
A example without lodash, just Hooks.
UseDebounce.js
import { useEffect, useCallback } from 'react';
export default function useDebounce(effect, dependencies, delay) {
const callback = useCallback(effect, dependencies);
useEffect(() => {
const timeout = setTimeout(callback, delay);
return () => clearTimeout(timeout);
}, [callback, delay]);
}
App.js
import React, { useState } from 'react';
import useDebounce from './useDebounce';
import data from './data';
export default function App() {
const [search, setSearch] = useState('');
const [filteredTitle, setFilteredTitle] = useState([]);
// DeBounce Function
useDebounce(() => {
setFilteredTitle(
data.filter((d) => d.title.toLowerCase().includes(search.toLowerCase()))
);
}, [data, search], 800
);
const handleSearch = (e) => setSearch(e.target.value);
return (
<>
<input
id="search"
type="text"
spellCheck="false"
placeholder="Search a Title"
value={search || ''}
onChange={handleSearch}
/>
<div>
{filteredTitle.map((f) => (
<p key={f.id}>{f.title}</p>
))}
</div>
</>
);
}
