REST route for Nette Framework

Route automatically maps CRUD to Presenters and actions in the defined module. And creates parameters which are accessible in Presenter.

• format
• id (autodetected)
• associations (an array with associations)
• data (raw data from the request)
• query (an array of items from the query string)

Format detection:

Variable $format is detected from HTTP header Accept. If header is not present Route tries to detect format from the URL (.../foo.json). If no format is in the URL Route use a default format json.

Installation:

The best way to install Nette-RestRoute is using Composer:

$ composer require nexendrie/rest-route

Usage:

<?php
use Nexendrie\RestRoute\RestRoute;

// $router is an instance of Nette\Application\Routers\RouteList  

// No parameters needed. Presenter name will be generated.
$router[] = new RestRoute;

// With module.
$router[] = new RestRoute('Api');

// With module and XML as a default format.
$router[] = new RestRoute('Api', 'xml');

// With URL module versioning
$router[] = (new RestRoute())
    ->useURLModuleVersioning(
        '/v[0-9\.]+/',     // Regex for URL version
        [                  // URL fragment to module mapping
          NULL => 'V1',    // Default version module is V1
          'v1' => 'V1',    // /v1 to module V1
          'v2' => 'V2'     // /v2 to module V2
        ]
    );

First parameter is a name of the module where the route will send a Request. URL prefix will be generated. See examples.

Examples:

NULL      => /<generated presenter name>
'Api'     => /api/<generated presenter name>
'My:Api'  => /my/api/<generated presenter name>
...

Second parameter is default format. By default the default format is json. RestRoute support only 2 formats:

• json (default)
• xml

Examples

Read all:

URL: /api/users → \ApiModule\UsersPresenter::actionReadAll
HTTP HEADER Accept: application/json
Method: GET
Request body: Empty
Params:

format = json
associations = array(0)
data = ""
query = array(0)

Flag readAll was dropped and Route automatically generate action readAll if no Resource ID was not found in the URL.

URL versioning:

RestRoute provides you with option to version your API in URL. Each version is represented by separate module in your application.

First, you define regexp which is used to detect if the version parameter is present in URL. It must be in the begging of the path. Then, you define version to module mapping. NULL key stands for default module, if version parameter doesn't get detected.

<?php
use Nexendrie\RestRoute\RestRoute;

$router = new \Nette\Application\Routers\RouteList();
...
$router[] = (new RestRoute('Api')) // Optional module
    ->useURLModuleVersioning(
        RestRoute::MODULE_VERSION_PATH_PREFIX_PATTERN,     // Regex for URL version
        [                  // URL fragment to module mapping
          NULL => 'V1',    // Default version module is V1
          'v1' => 'V1',    // /v1 to module V1
          'v2' => 'V2'     // /v2 to module V2
        ]
    );

RestRoute will now map your requests to presenters like this (URL -> Presenter):

/api/foo        ->  Api:V1:Foo
/api/v1/foo     ->  Api:V1:Foo
/api/v2/foo     ->  Api:V2:Foo

File uploads:

RestRoute reads standard PHP input and data puts to $data param in action. This is fit for one file upload or upload with chunks because it is a RAW data.

For multiple file upload RestRoute just set files when creates \Nette\Application\Request. In presenter just inject \Nette\Application\Request service and use these files.

<?php
class FooPresenter {
  /** @var \Nette\Application\Request @inject */
  public $request;

  public function actionCreate () {
    $files = $this->request->getFiles();
  }
}
