Function extendStatus

Enriches a status object by appending request metadata, including its originating message ID and a resolved request state derived from the status contents.

This serves as a post-processing step after a status has been extracted from a message.

Returns

An operator that transforms each emitted status into an augmented status object.

Example

source$.pipe(
  extendStatus({ statusKey: 'deviceInfo', messageId: 'req-123' })
).subscribe(status => {
  console.log(status.messageId);
  console.log(status.request); // e.g. "pending", "succeeded", "failed"
});
