ZID is my first foray into Shopify app development. I used the official Shopify Rails engine to get up and running quickly. After toying with a few ideas, I settled on making an app to find and delete products with 0 inventory. The use case is for vendors with large amounts of low-inventory products such as a used book store. And the result of this is zid.
Here are a few screenshots of it in action:
All pretty simple stuff. I used Bootstrap and DataTables on the front-end. The products are indexed in ElasticSearch for quick retrieval.
The app is currently being reviewed by Shopify, so I'll update this article when I have a link to it in the Shopify App Store.
