Shopify Hydrogen · 2025

Gymshark-style headless Shopify storefront

A headless Shopify build that recreates the Gymshark shopping experience: hero-driven homepage, mega menu navigation, faceted product grids, live search, and a sliding cart. The frontend is powered by Hydrogen on top of the Shopify Storefront & Cart APIs, with React handling variant selection and cart updates without full page reloads.

Gymshark-style Hydrogen storefront homepage

Global navigation & mega menu

The header mirrors Gymshark’s layout: brand mark, primary collections (Women, Men, Accessories), and a large mega menu with featured content. On a Hydrogen build this becomes a server-driven layout, sourced from Shopify navigation and CMS-friendly metafields.

  • • Mega menu columns for Trending, Products, Accessories, and Collections.
  • • Featured promotional tiles on the right with full-bleed imagery.
  • • Navigation modelled in Shopify menus so marketers can adjust structure without touching code.

Product discovery: collections, filters & live search

Collection grid with quick-add

High-density product grid with hover states, colorways, sale pricing, and quick-add to cart. Perfect for shoppers who know exactly what they want.

Faceted filtering overlay

Slide-in filter panel for product type, fit, size, and more. In Hydrogen this is wired to the Storefront API so filters update the grid without a full page reload.

Product filter overlay

Instant search results

Search overlay that returns matching products as you type, with thumbnails and pricing. Ideal place to plug in Storefront search or Algolia for larger catalogs.

Cart drawer overview

A sliding cart that appears over any page. Shoppers can adjust quantities or jump straight into checkout from the drawer.

Product page with AJAX variant selection

The product page is built around a large image gallery and a tight purchase panel. Choosing a size or color updates the active variant instantly, with availability and pricing coming from Shopify. In the Hydrogen implementation, these state changes are handled entirely in React rather than via full Liquid page reloads.

  • • Multi-image gallery with thumbnails that sync with variant selection.
  • • React-powered variant picker that calls the Cart API to add the correct variant without a page refresh.
  • • Notes field, delivery & returns block, and quantity stepper to mirror a real DTC purchase flow.
  • • “Add to cart” pushes to the cart drawer and keeps the shopper on the product or collection page.
Cart and checkout summary

Cart summary & checkout progression

The cart page mirrors a full Gymshark-style funnel, including progress steps, order summary, and reassurance blocks about shipping and returns. In a Hydrogen setup this page is backed by the Shopify Cart API and redirects into the hosted checkout when the shopper is ready to pay.

  • • Cart line items fully in sync with the cart drawer and quick-add buttons.
  • • Progress indicator across Bag → Information → Shipping → Payment → Complete.
  • • Hooks for upsells, payment plans, and shipping thresholds using cart-level metafields or custom logic.

What I’m building

  • • Recreating Gymshark’s core UX in a headless setup: homepage hero blocks, mega menu, collection grids, and product detail pages.
  • • Implementing a React-based variant selector that talks to the Cart API, replacing traditional Liquid + form submissions.
  • • Building a faceted filtering system for collections using Storefront API queries and URL-based filter state.
  • • Wiring up live search, cart drawer, and cart page so all surfaces stay perfectly in sync.
  • • Preparing the project to plug into real Shopify data and deploy as a production-ready Hydrogen storefront.
