When designing a new PureScript library, I need to decide whether to expose both Effect and Aff interfaces or to bet on a future unified effect monad. The Effect type tracks synchronous side effects through a phantom effect row, while Aff layers asynchronous, cancellable computations on top of that foundation. Today the language keeps these monads distinct,
Managing Side Effects in Retry Logic When implementing retry mechanisms within the Aff monad for external API integrations, ensuring that network failures do not result in duplicate writes is a critical design requirement. While PureScript provides the necessary primitives for asynchronous delays and recursive loops to handle exponential backoff, the coordin
Concurrency in the Aff Monad PureScript manages asynchronous operations through the Aff monad, which leverages the JavaScript event loop to handle non-blocking I/O. While primitives like parallel and race allow multiple computations to initiate concurrently, the underlying execution remains single-threaded. Resource Contention and Scheduling When deploying a
