Properties

expect

expect: Partial<{
    lastMsgID: string;
    lastSequence: number;
    lastSubjectSequence: number;
    streamName: string;
}>

Set of constraints that when specified are verified by the server. If the constraint(s) doesn't match, the server will reject the message. These settings allow you to implement deduplication and consistency strategies.

headers

headers: MsgHdrs

Headers associated with the message. You can create an instance of MsgHdrs with the headers() function.

msgID

msgID: string

A string identifier used to detect duplicate published messages. If the msgID is reused within the stream's duplicate_window, the message will be rejected by the stream, and the PubAck will mark it as a duplicate.

timeout

timeout: number

The number of milliseconds to wait for the PubAck
