Introducing NextShopKit: A Modern SDK for Headless Shopify Development with Next.js

1. Introduction

If you've ever tried building a custom Shopify storefront with Next.js, you know the potential is massive, but so is the pain. The freedom of a headless architecture means you're not shackled to rigid templates. But with great power comes great boilerplate.

From managing cart logic and fetching product data to handling metafields (especially custom ones), developers often find themselves tangled in a web of repetitive tasks. If you're a beginner, it can feel overwhelming. If you're experienced, it's just plain tedious.

You shouldn’t have to spend your weekend debugging cart states when you could be shipping features or enjoying a cold brew. That’s why we built NextShopKit: to take the grunt work out of building blazing-fast, modern ecommerce sites with Shopify and Next.js.

2. What is NextShopKit?

Copy link

NextShopKit is a lightweight, developer-friendly SDK designed specifically for Next.js applications. It brings you plug-and-play functions like getProduct, getProducts, createCart, and built-in support for metafields, all with zero configuration.

But it's more than just a function library:

• It comes with React Context for cart state management.

• It supports custom metafield types out of the box.

• It works seamlessly with SSR (Server Side Rendering) and ISR (Incremental Static Regeneration).

Let’s say you’re building a storefront over the weekend for a client launch. With NextShopKit, you can plug in your product data, enable a cart in minutes, and push live without touching the Storefront API directly.

3. Who Is It For?

Copy link

NextShopKit is for anyone building custom Shopify experiences using Next.js:

• Solo developers launching side projects or client sites

• Agencies delivering bespoke ecommerce solutions

• SaaS builders who need Shopify integration at scale

• Indie hackers chasing their next big idea

If you love writing clean, scalable code and hate reinventing the wheel, NextShopKit is for you.

4. Core Features

5. Quick Start

Copy link

🧱 Installation

Copy link

Install the SDK and configure your environment to start building your Shopify headless storefront with Next.js.

📦 Install the package

Copy link

Use your favorite package manager to add the SDK to your project:

1npm install @nextshopkit/sdk
2# or
3yarn add @nextshopkit/sdk
4# or
5pnpm add @nextshopkit/sdk

🌐 Shopify API Access

Copy link

In your .env.local, define the following variables:

1NEXT_PUBLIC_SHOPIFY_ACCESS_TOKEN=your-storefront-access-token
2NEXT_PUBLIC_SHOPIFY_STORE_DOMAIN=your-shop.myshopify.com

You can get the Storefront Access Token and Store Domain from your Shopify admin:

• Go to Apps > Develop Apps

• Create or use an existing private app

• Enable Storefront API access

• Copy the generated Access Token

🧠 Suggested Project Structure

Copy link

We recommend creating a centralized client for typed access and shared options. Create your Shopify SDK wrapper under:

lib/NextShopKit/client.ts

Example Setup

Copy link

1import {
2  createShopifyClient,
3  FetchProductResult,
4  FetchProductsResult,
5  GetCollectionOptions,
6  FetchCollectionResult,
7  GetProductOptions,
8} from "@nextshopkit/sdk";
9
10const client = createShopifyClient({
11  shop: process.env.NEXT_PUBLIC_SHOPIFY_STORE_DOMAIN!,
12  token: process.env.NEXT_PUBLIC_SHOPIFY_ACCESS_TOKEN!,
13  apiVersion: "2025-01",
14  enableMemoryCache: true,
15  defaultCacheTtl: 300,
16  enableVercelCache: true,
17  defaultRevalidate: 60,
18});
19
20export const getProduct = async (
21  args: GetProductOptions
22): Promise<FetchProductResult> => client.getProduct(args);
23
24export const getCollection = async (
25  args: GetCollectionOptions
26): Promise<FetchCollectionResult> => client.getCollection(args);
27
28export default client;

🛡️ API Security and Client Usage

Copy link

Certain features like cart context require client-side interaction, which means you will need to expose non-sensitive values via NEXT_PUBLIC_ environment variables.

To maintain security:

• Do not expose your Shopify access token directly.

• Only expose safe, non-sensitive values like store domain via NEXT_PUBLIC_SHOPIFY_STORE_DOMAIN.

• Use the SDK in:

  • Server components ("use server")

  • API routes

  • Route Handlers or app/api (App Router)

🚀 PRO Version (Coming Soon)

Copy link

The PRO version unlocks advanced features like:

• Metaobjects

• Blogs & Articles

• Product Recommendations

• Advanced Cart

• Localization

• Shopify Search

After purchase, you’ll receive a unique token to unlock PRO features via environment variable.
