DESCRIPTION

Mojolicious::Plugin::REST adds various helpers for RESTful CRUD operations via HTTP to the app.

As much as possible, it tries to follow 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
