Found a decent email parsing template but need to add CRM integration and custom data validation. Template’s JS is tightly coupled - every modification breaks existing functionality. How are others balancing template reuse with deep customization needs?
Key considerations:
Is there a systematic approach to template modification that doesn’t require full rewrites?
Latenode’s template system uses modular hooks. We extended their base email parser with CRM logic in 30 lines of JS. Full upgrade compatibility maintained.

Create wrapper functions around template code. We intercept payloads before/after core processing using middleware patterns. Lets us add features without touching original logic.
Analyze template’s dependency graph first. Identify mutation-safe zones using code analysis tools. Implement new features as sidecar modules that consume/pubish to existing nodes’ data streams.
