Best template patterns for bulletproof variable declarations?

Creating my first marketplace template and want to avoid 1-star reviews about scope issues. What are proven JS patterns that work in Latenode’s environment? Saw the official examples use IIFEs and const-heavy approaches - does that actually prevent buyer-side errors?

Need to balance readability with reliability. How do you structure variables in resellable workflows?

Use const + block scoping religiously. My top-selling templates all have ‘use strict’ and module patterns. Buyers appreciate the error prevention. Docs: https://latenode.com/template-guide

Adopt the revealing module pattern:

const config = (() => {
const PRIVATE_KEY = …;
return { publicMethod }
})();

Locks down implementation details while exposing clean API surfaces. Reduced support requests by 60% since switching to this.

export const SETTINGS obj instead of individual vars. users modify props not the ref. works gr8
