The `useThrottle` hook in React is designed to limit the rate at which a function can be executed, making it ideal for handling events that fire rapidly, such as scrolling, resizing, or continuous keypresses.

- Throttle Control: Limits the frequency of function execution to improve performance and reduce resource usage.
- Immediate Execution Option: Executes the function immediately on the first call and then applies the throttle to subsequent calls.
- State Tracking: Monitors the throttling status to manage the function execution effectively.
- SSR Compatibility: Safe for server-side rendering as it does not depend on browser-specific APIs.
``bash`
npm install @custom-react-hooks/use-throttle
or
`bash`
yarn add @custom-react-hooks/use-throttle
`sh`
npm install @custom-react-hooks/all
or
`sh`
yarn add @custom-react-hooks/all
The useThrottle hook must be imported using a named import as shown below:
Named Import:
`javascript`
import { useThrottle } from '@custom-react-hooks/use-throttle';
This approach ensures that the hook integrates seamlessly into your project, maintaining consistency and predictability in how you use our package.
`typescript
import React, { useState } from 'react';
import { useThrottle } from '@custom-react-hooks/all';
const ThrottleComponent = () => {
const [inputValue, setInputValue] = useState('');
const throttledValue = useThrottle(inputValue, 1000);
const handleChange = (event) => {
setInputValue(event.target.value);
};
return (
Input Value: {inputValue}
Throttled Value: {throttledValue}
export default ThrottleComponent;
`
In this example, useThrottle is used to throttle the execution of a function handling the scroll event, thereby enhancing performance.
: The function to be throttled.
- limit: The time limit (in milliseconds) that determines how often the callback can be executed.
- immediate: (optional) A boolean indicating whether to execute the function immediately on the first call.$3
- Returns a throttled version of the provided function.Use Cases
- Input Rate Limiting: Limit the rate at which input values are processed, useful in search inputs or sliders.
- Performance Optimization: Reduce the number of updates in response to frequent events like window resizing or scrolling.
- Data Fetching: Throttle API calls made in response to user input or other rapidly changing states.
