10 Errors
| (require koyo/error) | package: koyo-lib |
This module exposes an error handling middleware that displays stack traces in the browser in a prettier way than the default web server error handler:
procedure
((wrap-errors debug?) handler) → (-> request? can-be-response?)
debug? : boolean? handler : (-> request? can-be-response?)
Wraps handler such that, when debug? is
#t, unhandled exceptions are caught, logged to standard
error using error-display-handler and formatted for display
in the web browser like in the screenshot above.
parameter
→ (-> request? can-be-response?) (current-production-error-page page) → void? page : (-> request? can-be-response?)
This parameter holds the procedure that is used to render error
pages when the debug? parameter passed to
wrap-errors is #f.
The default implementation is completely unstyled and simply states that an error occurred and the user should try again later.
