Installation

npm install @keyvaluesystems/react-star-rating-summary

You’ll need to install React separately since it isn't included in the package.

Usage

React Star Rating Summary can be directly used in your project by just providing the ratings props like this:

import React, { useState } from 'react';
import RatingSummary from '@keyvaluesystems/react-star-rating-summary';

function App() {
  const ratingValues = {
    5: 100,
    4: 200,
    3: 300,
    2: 1000,
    1: 400
  };

  return (
    <RatingSummary
      ratings={ratingValues}
    />
  );
};

export default App;

The ratings prop expects an object with star rating-id as key (ideally 1, 2, 3, 4 and 5) and count of the respective ratings as the value, encapsulating the distribution of user feedback for different ratings.

Note: The total rating count will be calculated by the package and bar length for each rating will be considered with respect to total count.

        Count: (ratingId) => ({color: countColors[ratingId]})
      }}
