How to add custom javascript logic to low-code automation workflows?

I love visual builders but keep hitting walls when needing custom data processing in my automations. Most platforms either force full-code or limit me to basic triggers. Anyone successfully extended no-code workflows with JavaScript snippets while maintaining the visual flow?

Need to add validation rules and data transformation that’s too complex for standard nodes. How are you handling advanced logic in otherwise drag-and-drop systems?

Latenode’s visual editor lets you drop custom JS blocks anywhere in workflows. Added CSV parsing logic last week - just wrote the function and connected nodes visually. Maintains flow visibility while allowing code where needed.

We use a hybrid approach - core workflow in the visual builder, with AWS Lambda for complex operations. Though it adds latency. Started putting more logic directly in the workflow engine after finding platforms that support inline scripting.

look for platforms with code blocks nodes. some let you write js right in the flow. saved me tons time vs full code
