First, run the development server:

npm run dev

Shopify won't allow non https apps even in development, use ngrok to setup a https tunnel to localhost like so:

ngrok http 3000

In the partner dashboard create an app, make note of the credentials and use the following as settings in app setup:

• App URL: https://{ngrok-url}
• Whitelisted Redirection URL(s): https://{ngrok-url}/auth/callback

To install the app on a Shopify shop construct a URL like the following:

https://{shop}.myshopify.com/admin/oauth/authorize?client_id={appKey}&scope={scopes}&redirect_uri={redirectUri}

• shop: The myshopify subdomain of the shop you wish to install on.
• appKey: Your app's API key, found in partner dashboard.
• scopes: Comma-separated list of scopes, e.g. read_products,read_customers
• redirectUri: Should be https://{appUrl}/auth/callback, this must also be added to Whitelisted Redirection URL(s) in partner dashboard for the app

The app requires some environment variables, when running locally it requires a .env file in the root of the project with the following:

• SESSION_PASSWORD: Password for encrypting sessions, must be at least 32 characters.
• GLOBAL_TOKEN_KEY: Key for the global token window object.
• SHOPIFY_APP_URL: The full URL of where the app is hosted.
• SHOPIFY_APP_KEY: Shopify App API key from partner dashboard.
• SHOPIFY_APP_SECRET: Shopify App API secret from partner dashboard.
• SHOPIFY_ADMIN_GRAPHQL_ENDPOINT: The admin GraphQL API endpoint to use in the proxy.
• FAUNA_DB_SECRET: Fauna db secret.
