Mastering the Art of Headless Commerce with Next.js and Shopify

With the rise of ecommerce, it’s an excellent time to break into the world of headless commerce. By combining Next.js, Shopify, and modern web development principles, you can create an online store that not only effectively delivers your products but creates a seamless user experience, boosts conversion rates, and scales your business. In this tutorial, we'll explore the world of headless commerce, as well as how to build, integrate, customize, and optimize your ecommerce website using Next.js and Shopify.

What is Headless Commerce?

Headless commerce is an approach where the frontend (or the “head”) is decoupled from the backend ecommerce platform. This separation allows developers to create custom user interfaces using any frontend framework, while still benefiting from the powerful backend capabilities of an ecommerce platform like Shopify. This approach serves both to boost performance and to offer greater flexibility, enabling fast and efficient customization of your online store without compromising on features or security.

Why Next.js and Shopify?

Next.js is a popular, server-rendered React framework that helps developers build high-performance, dynamic web applications. When combined with Shopify – a leading ecommerce platform – you have a powerful stack that efficiently handles product management, shopping carts, checkout, and more. Lastly, Next.js simplifies integration with Shopify using API-driven architecture, which further streamlines performance and customization.

Getting Started with Next.js & Shopify

To begin, make sure you have Node.js and npm installed on your system. Next, follow these steps to create a new Next.js app:

npm create next-app my-shop
cd my-shop
npm run dev

To integrate Shopify with your new app, sign up for a Shopify account or create a new development store. Then, navigate to the "Manage Private Apps" section in your Shopify admin dashboard and create a new private app, which in turn will provide you with an API key and password.

Fetching Data from Shopify

First, install the 'isomorphic-fetch' and '@shopify/shopify-api' packages using npm:

npm install isomorphic-fetch @shopify/shopify-api

Next, create a new API client in the 'lib' folder of your Next.js application. Create a file called 'shopify.js' and add the following code to set up the API client:

import { createClient } from '@shopify/shopify-api';
const client = createClient({
  domain: process.env.SHOPIFY_DOMAIN,
  apiKey: process.env.SHOPIFY_API_KEY,
  password: process.env.SHOPIFY_API_PASSWORD,
export default client;

Note that the above code uses environment variables for your Shopify domain, API key, and password. Make sure you add these to your '.env.local' file in the root of your project directory.

Displaying Products with Next.js

With the Shopify API client set up, you can now fetch data to display in your Next.js application. Create a new file called 'products.js' inside the 'pages' folder, which will serve as the main page for your online store. Here's some example code to fetch and display products:

import React from 'react';
import shopifyClient from '../lib/shopify';

export async function getServerSideProps() {
  const products = await shopifyClient.product.fetchAll();
  return {
    props: {
      products: JSON.parse(JSON.stringify(products)),

const Products = ({ products }) => {
  return (
      <h2>Our Products</h2>
        { => (
          <li key={}>

export default Products;

Adding a Shopping Cart and Checkout

To create a shopping cart and handle checkout, you'll want to use Shopify’s Storefront API. The process involves developing a custom Shopify checkout experience using Next.js and React. You'll need to fetch, add, and update the cart before directing users to the checkout page.

First, install 'shopify-buy' package:

npm install shopify-buy

Next, create a shopping cart context by adding a new file called 'cart-context.js' inside the 'lib' folder. This will manage the cart state throughout the application. Then, wrap your '_app.js' file in a CartProvider component to make the cart state accessible throughout your application.


By combining Next.js and Shopify, you'll be well on your way to mastering the art of headless commerce. Remember to customize and optimize your ecommerce website further to deliver the best user experience possible. This approach will ultimately improve performance, enhance the scalability of your business, and boost conversion rates. Happy coding!
