Function: getDefaultNatsBridgeConfig() ​

getDefaultNatsBridgeConfig(): object

Defined in: natsbridge/src/getDefaultNatsBridgeConfig.ts:4

Returns ​

commandResponsePublishTwice ​

commandResponsePublishTwice: "always" | "eventOnly" | "eventAndError" | "never"

Indicates if a command response should be published a second time. If the command response gets published, it will be published to the regular topic pattern.

If set to never, subscription might not get messages they are expecting because of the timing.

If set to always, every command response is published. Because there might not be a consumer for every message, the broker will store the messages until the defaultMessageExpiryInterval is reached. This might result in a high resource consumption of the broker.

If set to eventOnly, only success responses which have a event name set, are published twice. There, we expect, that an event has at least one consumer subscription and the broker does not unnecessarily stores messages for a long time.
