## Exception Handling
-By default Grape does not catch all unexpected exceptions. This means that the web server will handle the error and render the default error page as a result. It is possible to trap all exceptions by setting `rescue_all_errors true` instead. You may change the error format to JSON by using `error_format :json` and set the default error status to 200 with `default_error_status 200`. You may also include the complete backtrace of the exception with `rescue_with_backtrace true` either as text (for the :txt format) or as a :backtrace field in the json (for the :json format).
+Grape can be told to rescue certain (or all) exceptions in your
+application and instead display them in text or json form. To do this,
+you simply use the `rescue_from` method inside your API declaration:
class Twitter::API < Grape::API
- rescue_all_errors true
- rescue_with_backtrace true
- error_format :json
- default_error_status 200
-
- # api methods
+ rescue_from ArgumentError, NotImplementedError # :all for all errors
end
