Roda 3.87.0 Released

[jeremyevans]

Roda 3.87.0 has been released!

New Features

• A host_routing plugin has been added, for easier routing based on
  the request host. Example:

    plugin :host_routing do |hosts|
      hosts.to :api, "api.example.com", "api2.example.com"
      hosts.default :www
    end
  
    route do |r|
      r.api do
        # requests to api.example.com or api2.example.com
      end
  
      r.www do
        # requests to other domains
      end
    end

  The plugin also adds request predicate methods:

    route do |r|
      r.api? # true if the request is to api.example.com or api2.example.com
      r.www? # true for request for other domains
    end

  If the :scope_predicates plugin option is given, these predicate
  methods are also supported directly in block scope (no "r.").

  For more advanced cases, such as prefix matches on the host, the
  hosts.default method accepts a block. In this case, you should
  also call hosts.register to notify the plugin about what hosts
  the block could return:

    plugin :host_routing do |hosts|
      hosts.register :api
      hosts.default :www do |host|
        :api if host.end_with?(".api.example.com")
      end
    end

Other Improvements

• In the custom_block_results plugin, if the block passed to
  handle_block_result returns an object that is not a String,
  nil, or false, Roda no longer attempts to write it to the response
  body. Doing so is undesirable and would be a violation of the rack
  spec.

• Minor performance improvements have been made to the header_matchers
  plugin.
