Why can’t I find anything in Reference Overview | Docs about the actual functions? For example I would like to see documentation on getNodeParameter. When I go to the definition of this.getNodeParameter I just get a skeleton interface IExecuteFunctions.
No docs on core functionality other than JSDoc. The implementation for getNodeParameter is in core/src/NodeExecuteFunctions.ts. Go to Symbol leading to a type declaration in a /dist dir of another module is a side effect of this being a lerna monorepo.
That said, for regular node dev, there should be no need to delve into the implementation details.
