Next.js Building Shared Components

Introduction

Next.js is a popular React-based framework that allows developers to build static or server-side rendered applications. With Next.js, sharing UI components among different pages and applications becomes easy using built-in features like dynamic imports and server-side rendering. In this tutorial, we will explore building shared components and utilizing them across different pages or applications in Next.js.

Get Started

To get started with Next.js, ensure that you have Node.js and a code editor like VS Code installed on your computer. Here is a step-by-step guide to creating a new Next.js project and building shared components:

1. Install Next.js using the create-next-app command-line utility:

npx create-next-app my-app

2. Create a components folder in the src directory of your Next.js app. This folder will contain all your shared components. For example, let's create a simple Button component:

import React from 'react';

function Button(props) {
  return (
    <button className={props.className} onClick={props.onClick}>
      {props.title}
    </button>
  );
}

export default Button;

3. In your Next.js pages or components, import the shared component as follows:

import Button from '../components/Button';

function HomePage() {
  return (
    <div>
      <h1>Welcome to Next.js</h1>
      <Button title="Click me!" onClick={() => alert('Button clicked!')} />
    </div>
  );
}

export default HomePage;

4. That's it! You can now reuse the Button component across different pages and applications in your Next.js project.

Important Points

• Shared components in Next.js can be built as regular React components.
• When importing shared components, ensure that the path is relative to the file in which the component is being used.
• Shared components can be used across different pages and applications in your Next.js project, as long as they are in the same folder.

Summary

In this tutorial, we explored how to build shared components in Next.js. We created a simple Button component and reused it across a Next.js page. Don't forget to keep it simple by reusing components instead of duplicating code. This way, you can make your applications much more maintainable, scalable, and reusable.
