## Overview

This is a React Router template for an embedded Shopify app. A merchant enters through the login flow, then uses the authenticated app shell and its product-data demo; the demo creates a product, updates a variant, and upserts a metaobject through Shopify Admin GraphQL. The template also demonstrates additional app navigation and webhook handling for scope changes and uninstall cleanup. Session storage is configured through Prisma. Webhook and storage relationships are supported by the shown source; the additional page implementation was not sampled.

Main entry points: [`app/shopify.server.js`](https://github.com/mohd-owais-shah/for-practice-public/blob/main/app/shopify.server.js) (Shopify app services), [`app/routes/app._index.jsx`](https://github.com/mohd-owais-shah/for-practice-public/blob/main/app/routes/app._index.jsx) (Product demo action), [`app/routes/app.jsx`](https://github.com/mohd-owais-shah/for-practice-public/blob/main/app/routes/app.jsx) (Embedded app shell), [`app/db.server.js`](https://github.com/mohd-owais-shah/for-practice-public/blob/main/app/db.server.js) (Prisma client)
