Throwing Custom Errors from Effects: Simplifying Error Handling
Is there a simple way to throw a custom error on failure from an effect
?
I
'm extracting a util to a standalone lib and the user is not expected to know about Effect
, so I tried letting
runSync
runSync
, throw but I realised it converts the error to a string and the error metadata is hidden behind a
Cause
Cause
, which is not great
.
