App has been rejected due to basic requirements

[Recan]

Hello Dev Community, I have been working on an app using the Shopify Node CLI. The app has rejected by the reviewer and I suspect performance is the cause, unfortunately I couldn't find out the exact cause maybe I'm on a bad track but I'm doing my best to review Shopify requirements.

I tested the performance using the boilerplate provided by Shopify but I don't think it will do.

 

Otherwise, is there a way to find out exactly what we're missing ( check list or something ).

Resources used while working:

• Requirements for public apps on Shopify
• Getting your app approved
• Guidelines and Resources for Getting Listed in the Shopify App Store
• Submission to the Shopify App Store
