``bash`
npm install react-flexible-star-rating
Alternatively, you can use yarn or pnpm:
#### Using yarn
`bash`
yarn add react-flexible-star-rating
#### Using pnpm
`bash`
pnpm add react-flexible-star-rating
#### Using a Callback Function to Handle Rating Changes
This example demonstrates how to handle rating changes using a custom callback function. The initial rating value starts at 0, and the rating is logged to the console each time the user clicks on a star. If the user clicks the same rating again, it resets to 0.
`tsx
import { StarRating } from 'react-flexible-star-rating';
function App() {
const handleRatingChange = (rating: number) => {
// Logs the new rating; resets to 0 if the same rating is clicked again
console.log(New rating: ${rating});
};
/*
⚠️ Note
To enable half-star ratings with an initial value of 0,
set the isHalfRatingEnabled prop to true.
Example usages:
`
*/
return
}
#### Using useState Hook with a Handler Function
This example demonstrates how to manage the rating value using the useState hook while also logging the rating changes to the console.
`tsx
import { useState } from 'react';
import { StarRating } from 'react-flexible-star-rating';
function App() {
const ratingValue = 3.5;
const [rating, setRating] = useState(ratingValue);
const handleRatingChange = (newRating: number) => {
console.log(New rating: ${newRating});
setRating(newRating);
};
/*
⚠️ Important Note: Proper Usage of initialRating
❌ Incorrect (Avoid this):
initialRating
- Binding to state can cause half-ratings to behave like integers.
✅ Correct (Use one of these approaches):
- Static value:
- Defined variable:
const ratingValue = 3.5;
...
This ensures proper half-rating functionality of the component.
*/
return
}
`
#### Using setState Function Directly
This example demonstrates how to manage the rating value using the useState hook without needing a separate handler function. The state is updated directly when the user selects a new rating.
`tsx
import { useState } from 'react';
import { StarRating } from 'react-flexible-star-rating';
function App() {
const ratingValue = 3.5;
const [rating, setRating] = useState(ratingValue);
return
}
`
⚠️ Important Note for Next.js Users
When using this component in Next.js applications, you must add the "use client" directive at the top of your component file. This is because the star rating component uses React hooks (useState, useCallback), which can only be used in client-side components.
#### Sample Usage in Next.js
`tsx
'use client'; // ⚠️ Required: do not forget this line
import { useState } from 'react';
import { StarRating } from 'react-flexible-star-rating';
export default function RatingComponent() {
const initialRatingValue = 2;
const [rating, setRating] = useState(initialRatingValue);
return (
Current Rating: {rating}
