Build an embedded app with Rails, React, and Shopify App Bridge

This tutorial shows you how to build an embedded Shopify app with Rails 6 using the Shopify App gem, React, and Shopify App Bridge authentication.

The app uses session tokens to authenticate requests from the app frontend to the app backend. When you've completed this tutorial, any requests made to the protected /graphql endpoint of the app will be authenticated with an Authorization: Bearer <session-token> header.
