Shopify Hydrogen & GraphQL Storefront API Development | 2026

Launch your first Shopify Hydrogen app by configuring a new project in VSCode, installing dependencies with yarn, and running yarn dev to view localhost:3000 with a sign-in panel.

Create your first Shopify Hydrogen account by visiting shopify.com, starting for free, selecting your country/region, and signing up with Google or email.

Explore Remix routing with file-based paths, learn how the dollar sign denotes variables, optional parameters, and 404 handling, and review example routes like index.js, search.json, and account/[id].js.

Learn how Remix loader functions run on the server to fetch data before rendering, enabling data prefetching, safer server-side access to databases and APIs, and improved SEO and performance.

Explore client-side rendering in Remix apps, fetch and use loader data with useLoaderData, and implement dynamic routes and index pages to render personalized greetings.

Explore Remix's server side routing by implementing loader and action functions to handle get and post requests, returning JSON responses and testing with Postman.

Learn to create a standalone product item component in a Hydrogen and GraphQL storefront, pass product data and a key prop, and wire it into the app for reusable use.

Create a buy one, get one discount in the Shopify admin, then configure a gift product metafield (custom namespace) as a product variant for Hydrogen storefront integration.

Implement a gift product metafield in a Shopify hydrogen app using GraphQL by adding the meta field to product queries (namespace custom, key gift product) and updating related fragments.

Learn to automatically add a gift product to the cart using the cart form and server-side actions in Shopify Hydrogen.

Learn to automatically add a gift product to the cart by detecting the gift variant, reading the product variant ID, and pushing the gift item into the cart array.

Learn to automatically update gift and original product quantities in the Shopify Hydrogen cart by using the cart get and lines update actions, syncing increases and decreases.

Automate the removal of the gift product and the current item in a Shopify Hydrogen storefront by detecting input line IDs and removing the matching line IDs.

Learn to hide adjust buttons for free products by inspecting line parameters, checking cost and total amount, and conditionally rendering only the quantity when the item is free.

Learn how to replace a zero price with 'free' by editing the cart line price component in a Shopify Hydrogen storefront, using an isFree variable.

Learn what GraphQL is and how the storefront API, a headless storefront, fetches data to display products, build cards, manage cart objects, and work with Hydrogen or your own stack.

Learn how to use the storefront api with hydrogen apps by querying product data, including price range and total inventory, using code in visual studio code and the admin panel.

Learn how to use GraphQL playground on localhost to query shop data, fetch product names and price ranges, and explore fields and arguments via the Documentation Explorer.

Discover how to use variables in a GraphQL query for Shopify Hydrogen storefronts, including passing values with a dollar sign, defining variables in the query, and testing with different counts.

Learn to fetch multiple fields with a single GraphQL query, avoiding multiple rest api requests. Use handle arguments and variables to retrieve a specific product and preview results.

Learn how GraphQL fragments create reusable components and reduce repetitive query code by defining and reusing fragments like product with a price range and money values.

Learn to fetch cart details using a GraphQL query by obtaining the cart ID from browser storage, converting fragments to a get cart query, and testing the query in development.

Learn to display the campaign name for a free product by querying cart automatic discount allocations in GraphQL and showing the title and discount amount via the cart query fragment.

Learn to extract the campaign name from discount allocations and display it alongside the free product, using select options and conditional rendering for zero totals.

Show how to display price ranges in the search results by updating the product grid and integrating min and max variant prices with a money component.

Implement a min and max price filter in search by updating the search form and extending the GraphQL storefront query to use product filters with price min and max.

Learn to publish your application on vercel by signing up, linking GitHub, configuring environment variables, and deploying with a single deploy button.
