NAME

Web::API::Mapper - Web::API::Mapper is an API (Application Programming Interface) convergence class for mapping/dispatching API to web frameworks.

SYNOPSIS

my $m = Web::API::Mapper->new(  '/foo' => {
                post => [
                    '/bar/(\d+)' => sub { my $args = shift;  return $1;  }
                ]
                get =>  [ 
                    ....
                ]
            })->mount( ... );
my $ret = $m->post->dispatch( '/foo/bar' , { ... args ... } );
my $ret = $m->get->dispatch(  '/foo/bar' );
my $ret = $m->dispatch( '/foo/bar' , { args ... } );

$m->post->mount( '/foo' , [ '/subpath/to' => sub {  ....  } ]);
$m->mount( '/fb' => {  post => [  ... ] , get => [  ... ] }  )->mount( ... );

DESCRIPTION

Web::API::Mapper is an API (Application Programming Interface) convergence class for mapping/dispatching API to web frameworks.

This module is for reducing class coupling of web services on web frameworks.

Web frameworks are always changing, and one day you will need to migrate your code to the latest web framework. If your code heavily depends on your framework, it's pretty hard to migrate and it takes time.

by using Web::API::Mapper you can simply seperate service application and framework. you can simply mount these api service like Twitter ... etc, and dispatch paths to these services.

Web::API::Mapper is using Path::Dispatcher for dispatching.

TODO

Provide service classes for mounting.

Provide mounter for web frameworks.

ROUTE SPEC

API Provider can provide a route hash reference for dispatching rules.

post => [ '/path/to/(\d+)' => sub { } , ... ]

get => [ '/path/to/(\d+)' => sub { } , ... ]

fallback => sub { }

ACCESSORS

route

post

is a Web::API::Mapper::RuleSet object.

get

is a Web::API::Mapper::RuleSet object.

fallback

is a CodeRef, fallback handler.

FUNCTIONS

mount

dispatch

EXAMPLE

package Twitter::API;

sub route { {
    post => [
        '/timeline/add/' => sub { my $args = shift;  .... },
        '/timeline/remove/' => sub { ... },
    ],
    get => [
        '/timeline/get/(\w+)' => sub {  my $args = shift;  .... return $1 },
    ],
} }

package main;

# This will add rule path to /twitter/timeline/add/  ... etc
my $m = Web::API::Mapper->new( '/twitter' => Twitter::API->route );
$m->mount(  '/basepath' , {  post => [  ... ] } );
$m->post->mount( '/basepath' , [  ...  ]  );
$m->dispatch( '/path/to' , { args ... } );
