From OpenJS World 2023: How to Develop Custom Node-RED Connectors without Coding – Kazuhito Yokoi
Talk from Kazuhito Yokoi, Software Engineer, Hitachi, Ltd. at OpenJS World 2023 in Vancouver, Canada, May 10-12.
To promote the use of cloud services or devices from Node-RED, companies can easily publish their original connectors to the Node-RED flow library. But creating custom connectors is a time-consuming task because it requires coding with Node-RED-specific development rules. To solve this situation, Hitachi developed the Node generator tool as one of the Node-RED projects under the OpenJS Foundation. This tool can convert to custom connectors from various sources like OpenAPI documents. Recently, this tool has supported generating custom connectors from subflow as a new source. Using the subflow functionality, all Node-RED users are able to create their original connectors from the existing Node-RED flow without coding. In this talk, Kazuhito shows how to use the tool and integrate it with GitHub Actions to release connectors to the public semi-automatically.
Kazuhito’s slide deck is available here.
