Shopify

Covers the full Shopify development stack: building apps with GraphQL and REST APIs, creating checkout and admin extensions, developing Liquid themes, and managing webhooks and billing. You'll find CLI workflows for spinning up projects, patterns for common tasks like product queries and checkout UI components, and guidance on when to build an app versus an extension versus a theme. The GraphQL examples are current (2025-01 API version) and the distinction between extension types is well laid out. Most useful if you're building merchant tools or customizing the checkout flow, less relevant if you're just querying the API from an external service.
