useUpdateEffect Hook
The useUpdateEffect
hook is an enhanced version of React's useEffect
that is triggered only when dependencies update, skipping the effect on the component's initial mount. It's particularly useful for effects that need to run in response to specific changes after the initial rendering.
Features
- Skips Initial Render: Executes the effect only on updates, not during the initial component mount.
- Custom Cleanup Function: Similar to
useEffect
, it allows for a cleanup function to be returned from the effect. - Compatible with SSR: Designed to work seamlessly in server-side rendering environments.
Installation
Installing Specific Hook
npm install @custom-react-hooks/use-update-effect
or
yarn add @custom-react-hooks/use-update-effect
Installing Complete Package
npm install @custom-react-hooks/all
or
yarn add @custom-react-hooks/all
Importing the Hook
The useUpdateEffect
hook must be imported using a named import as shown below:
Named Import:
import { useUpdateEffect } from '@custom-react-hooks/use-update-effect';
This approach ensures that the hook integrates seamlessly into your project, maintaining consistency and predictability in how you use our package.
Usage
import React, { useState } from 'react';
import { useUpdateEffect } from '@custom-react-hooks/all';
const UpdateEffectComponent = () => {
const [count, setCount] = useState(0);
const [message, setMessage] = useState('');
useUpdateEffect(() => {
setMessage(`Effect ran at count: ${count}`);
}, [count]);
return (
<div>
<button onClick={() => setCount(c => c + 1)}>Increment</button>
<p>Count: {count}</p>
<p>{message}</p>
</div>
);
};
export default UpdateEffectComponent;
