Module: Roda::RodaPlugins::ErrorHandler

Defined in:
lib/roda/plugins/error_handler.rb

Overview

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.
