To observe modifications in the Redux store within useEffect, you can use the 'useSelector' hook from the react-redux library. The useSelector hook allows you to select and retrieve a specific piece of state data from the Redux store.
Here's an example implementation:
import React, { useEffect } from 'react';
import { useSelector } from 'react-redux';
const MyComponent = () => {
const myStateData = useSelector(state => state.myStateData);
useEffect(() => {
// This callback will run every time 'myStateData' changes in the Redux store
console.log('myStateData has been updated:', myStateData);
}, [myStateData]);
return (
// Render your component as normal
);
}
export default MyComponent;
In this example, the useEffect hook takes an array with a single dependency - 'myStateData'. This means that the useEffect callback will only run when 'myStateData' changes in the Redux store.
You can modify the selector function to retrieve different pieces of state data as needed.
