# Middleware Abstract class that needs to be implemented when creating a new middleware piece. The class provides access to the Vertx object and by default is not marked as a error handler middleware. If there is a need to create a new error handler middleware the isErrorHandler method should be overridden to return true. The current list of Middleware is: * [BasicAuth](middleware/BasicAuth.html), * [BodyParser](middleware/BodyParser.html), * [BridgeSecureHandler](middleware/BridgeSecureHandler.html), * [Compress](middleware/Compress.html), * [CookieParser](middleware/CookieParser.html), * [Csrf](middleware/Csrf.html), * [ErrorHandler](middleware/ErrorHandler.html), * [Favicon](middleware/Favicon.html), * [Limit](middleware/Limit.html), * [Logger](middleware/Logger.html), * [MethodOverride](middleware/MethodOverride.html), * [RequestProxy](middleware/RequestProxy.html), * [ResponseTime](middleware/ResponseTime.html), * [Router](middleware/Router.html), * [Session](middleware/Session.html), * [Static](middleware/Static.html), * [Timeout](middleware/Timeout.html), * [Vhost](middleware/Vhost.html). Using the extras project you get the following extra Middleware: * [JsonRestRouter].
