module Roda::RodaPlugins::ErrorHandler
The error_handler plugin adds an error handler to the routing, so that if routing the request raises an error, a nice error message page can be returned to the user.
You can provide the error handler as a block to the plugin:
plugin :error_handler do |e| "Oh No!" end
Or later via the error
class method:
plugin :error_handler error do |e| "Oh No!" end
In both cases, the exception instance is passed into the block, and the block can return the request body via a string.
If an exception is raised, the response status will be set to 500 before executing the error handler. The error handler can change the response status if necessary.
