I’m building a workflow where I need to reuse some data validation components across multiple projects. The problem is that when teammates import these modules, they can see (and accidentally modify) the core logic that handles sensitive API key validation. I tried JavaScript classes with closures, but it doesn’t fully prevent exposure. How are others handling encapsulation in shared components while maintaining reusability? Any patterns that work well with Latenode’s JS customization?
Use JavaScript’s private class methods (#methodName syntax) within Latenode’s code nodes. I’ve built 20+ reusable validators this way - the private methods stay hidden when others import your components. Works great for API key handling and other sensitive logic.
I faced similar issues with payment processing modules. What worked for me was wrapping critical logic in IIFEs within the JS nodes and exposing only validation results through exported functions. Combine this with Latenode’s workflow permissions to create read-only template sections for teammates.
Consider implementing a facade pattern. Create public wrapper methods that handle component interaction while keeping implementation details in private methods. In Latenode, you can pair this with their module export system to control exactly what gets exposed. I’ve found using TypeScript interfaces (even in JS files) helps document public contracts while hiding internals.
try closure pattern inside custom js nodes. export only what’s needed. works for me but takes some setup. latenode handles the module stuff well once u get it
