Lists are fundamental for displaying dynamic content in web applications. This guide will demonstrate how to implement lists effectively in a Next.js application, covering key concepts and providing step-by-step coding examples.
Prerequisites
Before starting, ensure you have:
- Basic knowledge of Next.js and React
- Node.js installed on your development environment
- A code editor and terminal ready
Steps for Implementing Lists in Next.js
Step 1: Setting Up Your Next.js Project
If you haven’t already set up a Next.js project, create one using:
npx create-next-app@latest nextjs-lists cd nextjs-lists
Step 2: Creating a Data Source
For this example, create a mock data source. You can use a JSON file or an API endpoint to fetch data.
data/products.json
[
{ "id": 1, "name": "Product 1", "price": 10 },
{ "id": 2, "name": "Product 2", "price": 20 },
{ "id": 3, "name": "Product 3", "price": 30 },
{ "id": 4, "name": "Product 4", "price": 40 },
{ "id": 5, "name": "Product 5", "price": 50 }
]
Step 3: Fetching and Rendering Data
Create a component to fetch and render the list of products.
components/ProductList.js
import React from 'react';
import products from '../data/products.json';
const ProductList = () => {
return (
<div>
<h2>Product List</h2>
<ul>
{products.map(product => (
<li key={product.id}>
{product.name} - ${product.price}
</li>
))}
</ul>
</div>
);
};
export default ProductList;
Step 4: Using the ProductList Component
Use the ProductList component in your Next.js pages to display the list of products.
pages/index.js
import Head from 'next/head';
import ProductList from '../components/ProductList';
export default function Home() {
return (
<div>
<Head>
<title>Next.js Lists Example</title>
<meta name="description" content="Implementing lists in Next.js for dynamic content display." />
<link rel="icon" href="/favicon.ico" />
</Head>
<main>
<ProductList />
</main>
</div>
);
}
Step 5: Styling Your List
Apply CSS styles or frameworks like Tailwind CSS to enhance the appearance of your list components.
Step 6: Running Your Next.js Application
Start your Next.js development server:
npm run dev
or
yarn dev
Open your browser and navigate to http://localhost:3000 to see your list of products rendered dynamically.
Conclusion
Implementing lists in Next.js allows you to display dynamic content efficiently. By following these steps, you can fetch and render data seamlessly, enhancing the user experience with organized and responsive list components in your Next.js applications.

Implementing Lists in Next.js – FAQs
Lists in Next.js are components used to dynamically render and display data in a structured format.
Create a reusable component that maps over data and renders each item in a list format using JSX.
Yes, you can fetch data from APIs or use local JSON files to populate lists in Next.js.
Pass data as props from parent components to the list component, ensuring dynamic content rendering.
Keys help React identify which items have changed, are added, or are removed. They should be unique among siblings.
