NAME

       Web::Dispatch::HTTPMethods - Helpers to make RESTFul Dispatchers Easier

SYNOPSIS

	   package MyApp:WithHTTPMethods;

	   use Web::Simple;
	   use Web::Dispatch::HTTPMethods;

	   sub as_text {
	     [200, ['Content-Type' => 'text/plain'],
	       [$_[0]->{REQUEST_METHOD}, $_[0]->{REQUEST_URI}] ]
	   }

	   sub dispatch_request {
	     sub (/get) {
	       GET { as_text(pop) }
	     },
	     sub (/get-head) {
	       GET { as_text(pop) }
	       HEAD { [204,[],[]] },
	     },
	     sub (/get-post-put) {
	       GET { as_text(pop) }  ## NOTE: no commas separating http methods
	       POST { as_text(pop) }
	       PUT { as_text(pop) }
	     },
	   }

DESCRIPTION

       Exports the most commonly used HTTP methods as subroutine helps into your Web::Simple based application.  Additionally adds an automatic
       HTTP code 405 "Method Not Allow" if none of the HTTP methods match for a given dispatch and also adds a dispatch rule for "HEAD" if no
       "HEAD" exists but a "GET" does (in which case the "HEAD" returns the "GET" dispatch with an empty body.)

       We also add at the end of the chain support for the OPTIONS method (if you do not add one yourself.  This defaults to http 200 ok + Allows
       http headers.

       Also we try to set correct HTTP headers such as "Allows" as makes sense based on your dispatch chain.

       The following dispatch chains are basically the same:

	   sub dispatch_request {
	     sub (/get-http-methods) {
	       GET { [200, ['Content-Type' => 'text/plain'], ['Hello World']] }
	     },
	     sub(/get-classic) {
	       sub (GET) { [200, ['Content-Type' => 'text/plain'], ['Hello World']] },
	       sub (HEAD)  { [200, ['Content-Type' => 'text/plain'], []] },
	       sub (OPTIONS)  {
		 [200, ['Content-Type' => 'text/plain', Allows=>'GET,HEAD,OPTIONS'], []];
	       },
	       sub () {
		 [405, ['Content-Type' => 'text/plain', Allows=>'GET,HEAD,OPTIONS'],
		  ['Method Not Allowed']]
	       },
	     }
	   }

       The idea here is less boilerplate to distract the reader from the main point of the code and also to encapsulate some best practices.

       NOTE You currently cannot mix http method style and prototype sub style in the same scope, as in the following example:

	   sub dispatch_request {
	     sub (/get-head) {
	       GET { ... }
	       sub (HEAD) { ... }
	     },
	   }

       If you try this our code will notice and issue a "die".	If you have a good use case please bring it to the authors.

   EXPORTS
       This automatically exports the following subroutines:

	   GET
	   PUT
	   POST
	   HEAD
	   DELETE
	   OPTIONS
