TransformStream creates a readable/writable pair with processing logic in between. The transform() function executes on write, not on read. Processing of the transform happens eagerly as data arrives, regardless of whether any consumer is ready. This causes unnecessary work when consumers are slow, and the backpressure signaling between the two sides has gaps that can cause unbounded buffering under load. The expectation in the spec is that the producer of the data being transformed is paying attention to the writer.ready signal on the writable side of the transform but quite often producers just simply ignore it.

The series of Command objects generated by the pipeline is then run by an interpreter using runEffect(checkoutFlow(cartSummary)). Because our business logic consists of pure functions that interact with the world only through data, we can record those interactions simply by adding a few hooks for services like OpenTelemetry. And if we can record them, we can replay them deterministically. Best of all, there’s no need to mock a single database or external service.
