Procedures to develop Node-RED node from OpenAPI document
In this post, I will explain how to use the “Node generator” which makes it easy to create Node-RED nodes.
What is the Node generator?
After Hitachi research & development group released this tool as open-source software, it has been managed as the sub-project of the Node-RED project under the OpenJS Foundation (Linux Foundation). Currently, the Node-RED development community has enhanced the functionality of this tool in a cooperative way.
As of now, not only Hitachi but also Node-RED user companies like Cisco and IBM have used this tool to develop their original nodes as you can see on the following websites.
- Use case in Cisco: https://developer.cisco.com/meraki/meraki-dashboard-api-node-red-node/
- Use case in IBM US: https://developer.ibm.com/tutorials/use-node-red-node-generator-to-create-new-nodes-from-apis-and-services/
What is the OpenAPI document?
OpenAPI document is a standard format to describe the specification of the REST API.
The OpenAPI document contains information about the description of the REST API, HTTP methods about how to access the REST API in YAML or JSON format as above example.
Generating Node-RED node from OpenAPI document
From now on, I will try to generate the Node-RED node from the OpenAPI document. In the following procedures, I will use the OpenAPI document of the REST API which retrieves the location information of the International Space Station (ISS).
