What it is

Helps build custom apps directly on the Shopify platform.

Real use case example

"A founder, Sarah, wants a custom product recommendation feature on her Shopify store. She sets up the Shopify app in 5 minutes, imports her existing product catalog, and uses Ruby to create logic-based recommendations."

When to use it

•You're a Ruby developer looking to create a Shopify app
•You want to leverage the Shopify API to integrate your application with Shopify stores
•You need a robust and scalable solution for building Shopify apps with a large number of users

Ready-to-paste prompt

To retrieve a list of products from a Shopify store, use the following command: `ShopifyAPI::Product.find(:all, params: { limit: 10 })`

Heads up: Make sure you have a Shopify Partner account and a test store set up, as you'll need to configure your app's API credentials and test the integration with a real Shopify store
