Build a Star Rating Component in Next.js

Sure, creating a custom Star Rating component in Next.js involves creating a reusable React component that allows users to rate something using stars. Let's create a simple Star Rating component from scratch. We'll use React state to manage the rating and handle user interactions.

Prerequisites:

Before we begin, ensure that you have Node.js and npm (Node Package Manager) installed on your system. Additionally, you should have NestJS CLI installed globally. You can install it with the following command:

Installation

1. Setting Up the Project:

2. Add TailwindCSS:

Initialize the tailwind.

3. Configure your tailwind.config.js file

4. Add Tailwind layers to the globals.css

5. Create a new folder named Rating in the components folder:

6. Create 5 new files for Rating and Star Components:

Rating.tsx
Rating.props.ts
Rating.module.css
Star.tsx
Star.props.ts

7. Let's begin with the Star Component:

Modify the Start.props.ts file:

Here we are extending the DetailedHTMLProps to provide the all necessary props as onClick, onMouseEnter, onMouseLeave, TabIndex, and other.

Modify Star.tsx

8. Next step: modify the Rating.props.ts file:

9. New let's create the Rating.tsx file:

Rating.module.css

Rating.props.ts

Rating.tsx

10. Use the Rating component in your app router. Open app/page.tsx and import and use the component:

We need also to provide the setRating function to the component.

11. Run your Next.js app:

Visit http://localhost:3000 in your browser, and you should see your custom Star Rating component.

This example is a simple representation of a star rating component. You can customize it further by adding styles, animations, and additional features based on your requirements.
