While running, a W3bstream node emits internal Event Messages when something relevant happens. A W3bstream event can be currently generated for one of the following reasons:
  • A data message is received on an HTTP API project endpoint
  • A data message is published on an MQTT project topic
  • A smart contract event is detected by a blockchain monitor
  • A certain blockchain height is detected by a chain height monitor
Once a W3bstream event is emitted, if a matching strategy is found for that event, it will be routed to the respective Project's applet that contains the destination handler function.
