NelmioApiDocBundle

, _(*1)

The NelmioApiDocBundle bundle allows you to generate a decent documentation for your APIs., _(*2)

Important: This bundle is developed in sync with symfony's repository. For Symfony 2.0.x, you need to use the 1.* version of the bundle., _(*3)

Installation

Add this bundle to your composer.json file:, _(*4)

{
    "require": {
        "nelmio/api-doc-bundle": "dev-master"
    }
}

// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new Nelmio\ApiDocBundle\NelmioApiDocBundle(),
    );
}

Import the routing definition in routing.yml:, _(*6)

# app/config/routing.yml
NelmioApiDocBundle:
    resource: "@NelmioApiDocBundle/Resources/config/routing.yml"
    prefix:   /api/doc

Enable the bundle's configuration in app/config/config.yml:, _(*7)

# app/config/config.yml
nelmio_api_doc: ~

Usage

The main problem with documentation is to keep it up to date. That's why the NelmioApiDocBundle uses introspection a lot. Thanks to an annotation, it's really easy to document an API method., _(*8)

The ApiDoc() annotation

The bundle provides an ApiDoc() annotation for your controllers:, _(*9)

``` php <?php, _(*10)

namespace Your\Namespace;, _(*11)

use Nelmio\ApiDocBundle\Annotation\ApiDoc;, _(*12)

class YourController extends Controller { /** * This the documentation description of your method, it will appear * on a specific pane. It will read all the text until the first * annotation. * * @ApiDoc( * resource=true, * description="This is a description of your API method", * filters={ * {"name"="a-filter", "dataType"="integer"}, * {"name"="another-filter", "dataType"="string", "pattern"="(foo|bar) ASC|DESC"} * } * ) */ public function getAction() { }, _(*13)

/**
 * @ApiDoc(
 *  description="Create a new Object",
 *  input="Your\Namespace\Form\Type\YourType",
 *  output="Your\Namespace\Class"
 * )
 */
public function postAction()
{
}

/**
 * @ApiDoc(
 *  description="Returns a collection of Object",
 *  requirements={
 *      {
 *          "name"="limit",
 *          "dataType"="integer",
 *          "requirement"="\d+",
 *          "description"="how many objects to return"
 *      }
 *  },
 *  parameters={
 *      {"name"="categoryId", "dataType"="integer", "required"=true, "description"="category id"}
 *  }
 * )
 */
public function cgetAction($id)
{
}

}, _(*14)


The following properties are available:

* `section`: allow to group resources

* `resource`: whether the method describes a main resource or not (default: `false`);

* `description`: a description of the API method;

* `deprecated`: allow to set method as deprecated (default: `false`);

* `filters`: an array of filters;

* `requirements`: an array of requirements;

* `parameters`: an array of parameters;

* `input`: the input type associated to the method (currently this supports Form Types, classes with JMS Serializer
 metadata, and classes with Validation component metadata) useful for POST|PUT methods, either as FQCN or as form type
 (if it is registered in the form factory in the container).

* `output`: the output type associated with the response.  Specified and parsed the same way as `input`.

* `statusCodes`: an array of HTTP status codes and a description of when that status is returned; Example:

``` php
<?php

class YourController
{
    /**
     * @ApiDoc(
     *     statusCodes={
     *         200="Returned when successful",
     *         403="Returned when the user is not authorized to say hello",
     *         404={
     *           "Returned when the user is not found",
     *           "Returned when somehting else is not found"
     *         }
     *     }
     * )
     */
    public function myFunction()
    {
        // ...
    }
}

Each filter has to define a name parameter, but other parameters are free. Filters are often optional parameters, and you can document them as you want, but keep in mind to be consistent for the whole documentation., _(*15)

If you set input, then the bundle automatically extracts parameters based on the given type, and determines for each parameter its data type, and if it's required or not., _(*16)

For classes parsed with JMS metadata, description will be taken from the properties doc comment, if available., _(*17)

For Form Types, you can add an extra option named description on each field:, _(*18)

``` php <?php, _(*19)

class YourType extends AbstractType { /** * {@inheritdoc} */ public function buildForm(FormBuilder $builder, array $options) { $builder->add('note', null, array( 'description' => 'this is a note', ));, _(*20)

    // ...
}

}, _(*21)


The bundle will also get information from the routing definition (`requirements`, `pattern`, etc), so to get the
best out of it you should define strict _method requirements etc.

### Other bundle annotations ###

Also bundle will get information from the other annotations:

* @FOS\RestBundle\Controller\Annotations\RequestParam - use as `parameters`

* @FOS\RestBundle\Controller\Annotations\QueryParam - use as `requirements` (when strict parameter is true), `filters` (when strict is false)

* @JMS\SecurityExtraBundle\Annotation\Secure - set `authentification` to true

* @Sensio\Bundle\FrameworkExtraBundle\Configuration\Cache - set `cache`

### PHPDoc ###

Route functions marked as @deprecated will be set method as deprecation in documentation.

#### JMS Serializer features ####

The bundle has support for some of the JMS Serializer features and use these extra information in the generated documentation.

##### Group Exclusion Strategy #####

If your classes use [JMS Group Exclusion Strategy](http://jmsyst.com/libs/serializer/master/cookbook/exclusion_strategies#creating-different-views-of-your-objects),
you can specify which groups to use when generating the documentation by using this syntax :

 ```
 input={
     "class"="Acme\Bundle\Entity\User",
     "groups"={"update", "public"}
 }
 ```

 In this case the groups 'update' and 'public' are used.

 This feature also works for the `output` property.

##### Versioning Objects #####

If your `output` classes use [versioning capabilities of JMS Serializer](http://jmsyst.com/libs/serializer/master/cookbook/exclusion_strategies#versioning-objects),
the versioning information will be automatically used when generating the documentation.

#### Form Types features ####

If you use `FormFactoryInterface::createdNamed('', 'your_form_type'`, then by default the documentation will use
the form type name as the prefix (`your_form_type[param]` ... instead of just `param`).

You can specify which prefix to use with the `name` key:

input = { "class" = "your_form_type", "name" = "" } ```, _(*22)

Documentation on-the-fly

By calling an URL with the parameter ?_doc=1, you will get the corresponding documentation if available., _(*23)

Web Interface

You can browse the whole documentation at: http://example.org/api/doc., _(*24)

, _(*25)

, _(*26)

Command

A command is provided in order to dump the documentation in json, markdown, or html., _(*27)

php app/console api:doc:dump [--format="..."]

The --format option allows to choose the format (default is: markdown)., _(*28)

For example to generate a static version of your documentation you can use:, _(*29)

php app/console api:doc:dump --format=html > api.html

By default, the generated HTML will add the sandbox feature if you didn't disable it in the configuration. If you want to generate a static version of your documentation without sandbox, use the --no-sandbox option., _(*30)

Configuration

You can specify your own API name:, _(*31)

# app/config/config.yml
nelmio_api_doc:
    name: My API

This bundle provides a sandbox mode in order to test API methods. You can configure this sandbox using the following parameters:, _(*32)

# app/config/config.yml
nelmio_api_doc:
    sandbox:
        authentication: # default null, if set, the value of the api key is read from the query string and appended to every sandbox api call
            name: access_token
            delivery: query # query or http_basic are supported
            custom_endpoint: true # default false, if true, your user will be able to specify its own endpoint
        enabled:  true # default: true, you can set this parameter to `false` to disable the sandbox
        endpoint: http://sandbox.example.com/ # default: /app_dev.php, use this parameter to define which URL to call through the sandbox
        accept_type: application/json # default null, if set, the value is automatically populated as the Accept header
        body_format: form # default form, determines whether to send x-www-form-urlencoded data or json-encoded data in sandbox requests
        request_format:
            method: format_param # default format_param, alternately accept_header, decides how to request the response format
            default_format: json # default json, alternately xml, determines which content format to request back by default

The bundle provides a way to register multiple input parsers. The first parser that can handle the specified input is used, so you can configure their priorities via container tags. Here's an example parser service registration:, _(*33)

#app/config/config.yml
services:
    mybundle.api_doc.extractor.custom_parser:
        class: MyBundle\Parser\CustomDocParser
        tags:
            - { name: nelmio_api_doc.extractor.parser, priority: 2 }

You can also define your own motd content (above methods list). All you have to do is add to configuration:, _(*34)

#app/config/config.yml
nelmio_api_doc:
    # ...
    motd:
        template: AcmeApiBundle::Components/motd.html.twig

Using Your Own Annotations

If you have developed your own project-related annotations, and you want to parse them to populate the ApiDoc, you can provide custom handlers as services. You just have to implement the Nelmio\ApiDocBundle\Extractor\HandlerInterface and tag it as nelmio_api_doc.extractor.handler:, _(*35)

# app/config/config.yml
services:
    mybundle.api_doc.extractor.my_annotation_handler:
        class: MyBundle\AnnotationHandler\MyAnnotationHandler
        tags:
            - { name: nelmio_api_doc.extractor.handler }

Look at the built-in Handlers., _(*36)

Credits

The design is heavily inspired by the swagger-ui project. Some icons from the Glyphicons library are used to render the documentation., _(*37)
