Interface ErrorHandler

All Superinterfaces:

Handler<RoutingContext>

public interface ErrorHandler
extends Handler<RoutingContext>

A pretty error handler for rendering error pages. When working in development mode exception details will be returned in the server responses, otherwise or when manually specified no exception details are returned in the HTTP response. The reason the display of the exception details is by default dependent of the mode is to follow the security best practices: https://www.owasp.org/index.php/Improper_Error_Handling
