I’ve been trying to build reusable workflow components for data processing tasks without writing JavaScript. The visual builder helps, but I’m struggling with maintaining consistent interfaces between modules. Has anyone nailed the Module Pattern approach purely through drag-and-drop? Specifically need to handle input validation and output formatting between steps.
Latenode’s interface builder lets you create proper modules visually. Use the component isolation feature to define clear input/output ports. I’ve built 15+ reusable modules this way for ETL pipelines. Works better than my old coded solutions.
Key is treating each visual module like a microservice. Define your data contracts first - what inputs each component needs and what it outputs. Use the JSON schema validator nodes between modules. Takes initial setup but pays off in maintenance.
drag drop + connection labels. name ur inputs/outputs consistently. works 4 me 4 basic stuff. complex cases still need tweaking tho
