This shift has created a massive opportunity for developers who understand Shopify’s Storefront API, Liquid templates, and modern frontend frameworks like React, Next.js, and Remix.

Whether you’re a beginner learning Shopify development or an experienced front-end developer looking to build high-performance custom stores, this guide explains everything you need to know about Shopify Storefront Development.

What Is the Shopify Storefront API?

The Shopify Storefront API lets developers build custom online stores using any framework they want. Unlike Shopify themes that rely on Liquid and the Online Store 2.0 editor, the Storefront API gives you full freedom over:

• UI

• Frontend structure

• Data fetching

• Performance

• Checkout integration

You can use the API to fetch products, collections, variants, cart information, and customer data, then render everything in your own custom frontend.

This is why many companies are now building headless Shopify stores using frameworks like:

• Next.js

• Remix

• Shopify Hydrogen

• React

• Vue

Why Headless Shopify Stores Are Growing in 2025

Headless commerce is one of the most searched Shopify topics this year. Brands prefer headless setups because they get:

1. Faster load speed

2. 100% custom UI

3. Better SEO control

4. Easy integration with apps and APIs

5. A smoother omnichannel experience

Shopify’s Storefront API makes headless development easier than ever. With features like product recommendations, GraphQL queries, and metafields, developers can build highly customized storefronts without touching Liquid.

Storefront API

Use for front-end tasks such as:

• Display products

• Show collections

• Add to cart

• Create cart

• Customer login/signup

• Headless checkout

Admin API

Use for back-end tasks like:

• Create products

• Manage inventory

For developers building custom storefronts, Storefront API is the main tool.
