Built-in middleware that wraps each mutation in an OTel-shaped span. Span name is cart.mutation.<kind>; attributes include the mutation kind and (when present) idempotency key. The resolved cart id is added after the inner call resolves; exceptions are recorded and rethrown.

Signature

function tracing(opts: { tracer: ITracer }): CartMiddleware;

Parameters

Returns

A that pipes mutations through a span.

Example

const kernel = createCart({
  adapter,
  middleware: [tracing({ tracer: openTelemetryTracer })],
});
