Since this package does not start with @types/, the types are not automatically included in your project. You need to add a reference to this package in your tsconfig.json:
The adapter opens a webserver for the ioBroker admin UI.
Base module for plugins for js-controller and adapters
Core module to be used in ioBroker adapters. Acts as the bridge to js-controller.
The Library contains the common utils for the ioBroker controller which can be used by db classes too, as they do not rely on the db (circular dependencies).
