Shopify Development

This is your reference when building anything on Shopify: apps that integrate external services, extensions that customize checkout or admin UI, or themes using Liquid templates. It covers the routing logic (when to build an app vs extension vs theme), CLI commands for scaffolding and deployment, GraphQL query patterns validated against the 2026-01 API, and webhook configuration including the mandatory GDPR endpoints. The troubleshooting section is honest about common gotchas like rate limits and HMAC verification. If you're doing Shopify development beyond basic tweaks, you'll want the GraphQL examples and access scope reference handy. The routing guide alone saves you from building the wrong thing.

ROUTING: What to Build

IF user wants to customize checkout OR add admin UI OR create POS actions OR implement discount rules: → Build an Extension (see references/extensions.md)

IF user wants to customize storefront design OR modify product/collection pages: → Build a Theme (see references/themes.md)

IF user needs both backend logic AND storefront UI: → Build App + Theme Extension combination
