`imports/api` vs `imports/utils` structure?

I am not clear about imports/api vs imports/utils structure?.
Could explain?

Can you expand on your question?

Technically speaking, there is no difference what so ever

I would like to create Select Opts data method to get customer collection info

<select name="customer">

It should place in api or utils?

It’s entirely up to you. Do whatever makes the most sense for you and your project

If you’re unsure, the Meteor guide suggests putting Collections and Methods in /api/ and not using utils at all

thanks again, I clear about this
