How to Develop Custom Node-RED Connectors Without Coding
summary
Demonstrates a reproducible 10-step pipeline that turns a Node-RED subflow export into a published npm connector by running Node generator inside GitHub Actions, producing a .tgz release which can be installed into Node-RED and added to the Flow Library. Shows concrete examples (JDBC, WMI, ZigSim, Stable Diffusion, React dashboard), describes package.json fields and release tag workflow, and reports successful commercial use in products and services, so the method both builds working connectors and automates publishing without writing Node-RED-specific code.
