I am happy to announce the release candidate of the official Node SDK:
It was a long journey, because the goal was to use code generation and many generators do not support all needed features. Therefore I was happy to find a new startup called fern: https://www.buildwithfern.com/
Their goal is to provide a workflow for multiple programming languages. Therefore Node is only the first step. The next SDK will be for Java, followed by python and the we will see what other platforms they come up with.
