1. Introduction

Shopify’s Storefront API allows developers to access product data programmatically. In this tutorial, we will fetch the top-selling products using Node.js and GraphQL, parse the data, and return it in a usable format.

2. Prerequisites

Before starting, ensure you have:

  • A Shopify store
  • Storefront API token
  • Node.js installed
  • Basic knowledge of JavaScript and Express
  • dotenv package installed


3. Setup Environment Variables

Create a .env file in your project root:

.env
bash
1SHOPIFY_DOMAIN=your-store-name.myshopify.com
2SHOPIFY_STOREFRONT_TOKEN=your_storefront_api_token

4. Install Dependencies

Install the necessary Node.js packages:

1npm install graphql-request dotenv

5. Initialize API Config

Create a config file to store API URL and tokens:

1import { request } from "graphql-request";
2import dotenv from "dotenv";
3dotenv.config();
4
5const SHOPIFY_DOMAIN = process.env.SHOPIFY_DOMAIN;
6const STOREFRONT_API_TOKEN = process.env.SHOPIFY_STOREFRONT_TOKEN;
7const API_URL = `https://${SHOPIFY_DOMAIN}/api/2025-01/graphql.json`;

6. Fetch Top-Selling Products

Use GraphQL to query the top-selling products:

1export const getTopSelling = async (req, res) => {
2  try {
3    const GET_TOP_SELLING = `
4      {
5        products(first: 4, sortKey: BEST_SELLING) {
6          edges {
7            node {
8              id
9              title
10              handle
11              featuredImage {
12                url
13              }
14              variants(first: 1) {
15                edges {
16                  node {
17                    price {
18                      amount
19                      currencyCode
20                    }
21                    compareAtPrice {
22                      amount
23                      currencyCode
24                    }
25                  }
26                }
27              }
28            }
29          }
30        }
31      }
32    `;
33
34    const data = await request(
35      API_URL,
36      GET_TOP_SELLING,
37      {},
38      { "X-Shopify-Storefront-Access-Token": STOREFRONT_API_TOKEN }
39    );
40
41    const products = data.products.edges.map((edge) => {
42      const node = edge.node;
43      const variant = node.variants.edges[0]?.node || {};
44      return {
45        id: node.id,
46        title: node.title,
47        handle: node.handle,
48        featuredImage: node.featuredImage,
49        price: variant.price || null,
50        compareAtPrice: variant.compareAtPrice || null,
51      };
52    });
53
54    res.json(products);
55  } catch (err) {
56    console.error("Top selling error:", err);
57    res.status(500).json({ error: "Failed to fetch top selling products" });
58  }
59};

7. Testing the Endpoint

Use Postman or Thunder Client:

1GET /api/top-selling

8. Conclusion

You have successfully implemented a Node.js endpoint to fetch Shopify top-selling products. You can now display this data on dashboards, homepages, or e-commerce frontends.
