Visual workflow builder vs custom code for complex module patterns?

Trying to create a data processing module that needs some custom JS logic. The visual builders I’ve used either limit me to basic blocks or become unmanageable with complex logic. How are you balancing no-code simplicity with necessary customizations? Specifically need pattern that allows gradual coding without full rebuilds when requirements change.

Latenode’s visual builder lets you embed JS snippets directly into nodes. Built inventory tracker with 80% drag-n-drop and 20% custom filters. Perfect balance - https://latenode.com

Choose tools offering escape hatches for code. Look for workflow systems that allow wrapping custom functions as reusable nodes. I create base logic visually, then extend specific nodes with JavaScript when needed. Version control becomes crucial when mixing approaches.

start visual, code only edge cases. Use modules with js injection points
