React JS is a powerful JavaScript library for building user interfaces, and it provides a flexible and efficient way to create reusable components. One common component in many web applications is a rating system, which allows users to provide feedback or rate certain items. In this article, we will explore how to create a rating component in ReactJS.

Prerequisite:

Steps to create React App and Install required modules

Step 1: You will start a new project using create-react-app command

npx create-react-app react-rating

Step 2: Now go to your react-rating folder by typing the given command in the terminal.

cd react-rating

Step 3: Install the dependencies required in this project by typing the given command in the terminal.

npm install --save styled-components
npm install --save react-icons

Now create the components folder in src then go to the components folder and create two files Rating.js and RatingStyles.js.

Project Structure: The file structure in the project will look like this.

Example: In this example, we will design a rating component, for that we will need to manipulate the App.js file and other created components file.

Rating.js

import React, { useState } from "react";
import { FaStar } from "react-icons/fa";
import { Container, Radio, Rating } from "./RatingStyles";
const Rate = () => {
    const [rate, setRate] = useState(0);
    return (
        <Container>
            {[...Array(5)].map((item, index) => {
                const givenRating = index + 1;
                return (
                    <label>
                        <Radio
                            type="radio"
                            value={givenRating}
                            onClick={() => {
                                setRate(givenRating);
                                alert(
                                    `Are you sure you want to give
                                    ${givenRating} stars ?`
                                );
                            }}
                        />
                        <Rating>
                            <FaStar
                                color={
                                    givenRating < rate || givenRating === rate
                                        ? "000"
                                        : "rgb(192,192,192)"
                                }
                            />
                        </Rating>
                    </label>
                );
            })}
        </Container>
    );
};
 
export default Rate;

                    

RatingStyles.js

import styled from 'styled-components';
 
export const Container = styled.div`
   display: flex;
   justify-content: center;
   align-items: center;
   min-height: 60vh;
   font-size: 60px;
`
export const Radio = styled.input`
   display: none;
`
export const Rating = styled.div`
   cursor: pointer;
`

                    

App.js

import './App.css';
import Rating from './components/Rating';
 
function App() {
    return (
        <Rating />
    );
}
 
export default App;

                    

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
