io.vertx.reactivex.ext.web.handler

## Class ErrorHandler

- java.lang.Object
- - io.vertx.reactivex.ext.web.handler.ErrorHandler

- All Implemented Interfaces:
    Handler<RoutingContext>

      public class ErrorHandler
      extends Object
      implements 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

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.
