Learn. Build. Deploy.

Go from a clean machine to a working Shopify app — Ruby on Rails backend, Polaris UI, theme app extension, and a live deployment you can use in a real store.

Rails + Shopify APIs
  • Develop apps with familiar Rails tooling and conventions to build a CRUD app.
  • Use Shopify's Admin API and GraphQL API to keep your app synced with merchant stores.
UI That Feels Native
  • Use Polaris to create fast, responsive admin experiences that feel like Shopify itself.
  • Use the power of React to add dynamic forms using Polaris' components.
Deploy & Publish
  • Deploy your app to production via a hosted server (Fly.io).
  • Add Theme App Extensions to surface app functionality in storefronts.
