API reference › @evolu/common › Task › AbortError
Defined in: packages/common/src/Task.ts:537
Error returned when a Task is aborted via AbortSignal.
This is structured-concurrency control flow, not a domain error. It plays a role similar to an interrupt: in most code, propagate it unchanged or ignore it when cleanup is already handled by the runtime.
The reason field is unknown by design — use typed errors for business
logic. If you need to inspect the reason, use type guards like
RaceLostError.is(reason).
When a piece of logic must continue once started, wrap it with
unabortable. That prevents ordinary mid-flight interruption, but it
does not erase AbortError from the type because the Task can still be
rejected before it starts, for example on an already-stopped Run. In
those cases, abort usually indicates a lifecycle bug, so use
assertNotAborted if you want to fail fast.
