We've just updated the mydigitalstructure npm module and example app code to use the same methodologies as used in the browser js based mydigitalstructure library - see https://learn.mydigitalstructure.cloud.

So now the same code that you create for the browser can be more easily implemented as Node.js code;

ie using:

• .init() to initialise and log on using settings.json
• .add() & .invoke() to add & invoke code to the controller layer
• .set() & .get() to store data locally 
• .cloud.retrieve(), .cloud.save() etc to store data on mydigitalstructure.cloud

The example app code (with commenting) is @
