DESCRIPTION

    Mojolicious::Plugin::REST adds various helpers for REST
    <http://en.wikipedia.org/wiki/Representational_state_transfer>ful CRUD
    <http://en.wikipedia.org/wiki/Create,_read,_update_and_delete>
    operations via HTTP to the app.

    As much as possible, it tries to follow RESTful API Design
    <https://blog.apigee.com/detail/restful_api_design> principles from
    Apigee.

    This module is inspired from Mojolicious::Plugin::RESTRoutes.

MOJOLICIOUS HELPERS

 rest_routes

    rest_routes shourtcut can be used to easily add RESTful routes for a
    resource. For example,

            $routes->rest_routes( name => 'User' );
            
            # Installs following routes (if $r->namespaces == ['My::App']) :-
            #+-------------+----------------+---------------------------------+
            #| HTTP Method |      URL       |              Route              |
            #+-------------+----------------+---------------------------------+
            #| GET         | /users         | My::App::User::read_all_users() |
            #| POST        | /users         | My::App::User::create_user()    |
            #| GET         | /users/:userid | My::App::User::read_user()      |
            #| PUT         | /users/:userid | My::App::User:update_user()     |
            #| DELETE      | /users/:userid | My::App::User:delete_user()     |
            #+-------------+----------------+---------------------------------+

    The target controller has to implement the following methods:

      * read_all_users

      * create_user

      * read_user

      * update_user

      * delete_user

MOJOLICIOUS HOOKS

    This module installs an before_render application hook, which gurantees
    JSON output in non dev mode.

OPTIONS

    Following options can be used to control route creation:

    name

      The name of the resource, e.g. 'User'. This name will be used to
      build the route URL as well as the controller name.

    readonly

      If true, no create, update or delete routes will be created.

    controller

      By default, resource name will be converted to CamelCase controller
      name. You can change it by providing controller name.

      If customized, this option needs a full namespace of the controller
      class.

    under

      This option can be used for associations. For Example:

          # Mojolicious
          $self->routes->rest_routes( name => 'Feature', under => 'User' );
          
          # Installs following routes (if $r->namespaces == ['My::App']) :-
              # +-------------+-------------------------------------------+-----------------------------------------+
              # | HTTP Method |                    URL                    |                  Route                  |
              # +-------------+-------------------------------------------+-----------------------------------------+
              # | GET         | /api/v1/users/:userid/features            | My::App::User::read_all_user_features() |
              # | POST        | /api/v1/users/:userid/features            | My::App::User::create_user_feature()    |
              # | GET         | /api/v1/users/:userid/features/:featureid | My::App::User::read_user_feature()      |
              # | PUT         | /api/v1/users/:userid/features/:featureid | My::App::User::update_user_feature()    |
              # | DELETE      | /api/v1/users/:userid/features/:featureid | My::App::User::delete_user_feature()    |
              # +-------------+-------------------------------------------+-----------------------------------------+

PLUGIN OPTIONS

    prefix

      If present, this option will be added before every route created.
      e.g.

          # Mojolicious
          $app->plugin(REST => { prefix => 'api' });
      
          # Installs following routes:
              # +-------------+--------------------+---------------------------------+
              # | HTTP Method |        URL         |              Route              |
              # +-------------+--------------------+---------------------------------+
              # | GET         | /api/users         | My::App::User::read_all_users() |
              # | POST        | /api/users         | My::App::User::create_user()    |
              # | GET         | /api/users/:userid | My::App::User::read_user()      |
          # ...

    version

      If present, api version given will be added before every route
      created (but after prefix). e.g.

              # Mojolicious
          $app->plugin(REST => { version => 'v1' });
      
          # Installs following routes:
              # +-------------+-------------------+---------------------------------+
              # | HTTP Method |        URL        |              Route              |
              # +-------------+-------------------+---------------------------------+
              # | GET         | /v1/users         | My::App::User::read_all_users() |
              # | POST        | /v1/users         | My::App::User::create_user()    |
              # | GET         | /v1/users/:userid | My::App::User::read_user()      |
          # ...

      And if both prefix and version are present

          # Mojolicious
          $app->plugin(REST => { prefix => 'api', version => 'v1' });
      
          # Installs following routes:
              # +-------------+-----------------------+---------------------------------+
              # | HTTP Method |          URL          |              Route              |
              # +-------------+-----------------------+---------------------------------+
              # | GET         | /api/v1/users         | My::App::User::read_all_users() |
              # | POST        | /api/v1/users         | My::App::User::create_user()    |
              # | GET         | /api/v1/users/:userid | My::App::User::read_user()      |
          # ...

    http2crud

      If present, given HTTP to CRUD mapping will be used to determine
      method names. Default mapping:

              get     ->  read
              post    ->  create
              put     ->  update
              delete  ->  delete
              get_col ->  read_all  # deaviates over best practices, 
                                    # but makes it simple to distinguish method names for
                                    # single resource vs for collection
