Caught myself copying the same data sanitization code between 8 different workflows. Heard about saving JS functions as custom nodes but worried about spaghetti code.
Experiment: Took a closure-heavy date parser and saved it as a node with configurable formats. Now my team uses it with different locale settings across projects.
What’s your approach? Any rules you follow for making maintainable code nodes?
I version my JS nodes like npm packages. Each gets its own test scenario using the dev/prod environments. Keep them focused - one function per node. Saved 40hrs/month on maintenance.

Create interface layers between your custom code and the rest of the workflow. I use adapter nodes that handle error trapping and data shaping. Makes the core logic portable between projects without dependency hell.
Treat code nodes like microservices. Enforce strict input/output contracts and add validation at node boundaries. I prefix all variables with the node name to prevent collisions. Document using JSDoc-style comments - Latenode’s AI can generate docs if you highlight the code and ask.
