Ding.js configuration

Ding.js configuration is composed of a JSON file that contains all information to setup the application.

  • mqtt: broker settings (for The Things Network)
  • data: an object that identifies the service of which the data will be received
    • entities: an array containing the keys that should be used from the payload_fields object.
  • metadata: an array containing the metadata entities that could be related with the nodes (using the dev_id)
    • Optionally some entities could be served as endpoints
