Laravel API Documentation Generator

Automatically generate your API documentation from your existing Laravel routes. Take a look at the example documentation.

php artisan api:gen --routePrefix="settings/api/*"

Installation

Require this package with composer using the following command:

$ composer require mpociot/laravel-apidoc-generator

Go to your config/app.php and add the service provider:

Mpociot\ApiDoc\ApiDocGeneratorServiceProvider::class,

Usage

To generate your API documentation, use the api:generate artisan command.

$ php artisan api:generate --routePrefix="api/v1/*"

This command will scan your applications routes for the URIs matching api/v1/* and will parse these controller methods and form requests.

Available command options:

Option	Description
output	The output path used for the generated documentation. Default: public/docs
routePrefix	The route prefix to use for generation - * can be used as a wildcard
routes	The route names to use for generation - Required if no routePrefix is provided
middleware	The middlewares to use for generation
noResponseCalls	Disable API response calls
noPostmanCollection	Disable Postman collection creation
actAsUserId	The user ID to use for authenticated API response calls
router	The router to use, when processing the route files (can be Laravel or Dingo - defaults to Laravel)
bindings	List of route bindings that should be replaced when trying to retrieve route results. Syntax format: `binding_one,id
force	Force the re-generation of existing/modified API routes
header	Custom HTTP headers to add to the example requests. Separate the header name and value with ":". For example: --header 'Authorization: CustomToken'

Publish rule descriptions for customisation or translation.

By default, this package returns the descriptions in english. You can publish the packages language files, to customise and translate the documentation output.

$ php artisan vendor:publish

After the files are published you can customise or translate the descriptions in the language you want by renaming the en folder and editing the files in public/vendor/apidoc/resources/lang.

How does it work?

This package uses these resources to generate the API documentation:

Controller doc block

This package uses the HTTP controller doc blocks to create a table of contents and show descriptions for your API methods.

/**
 * This is the short description
 *
 * This can be an optional longer description of your API call, used within the documentation.
 *
 */
 public function foo()

Result:

Form request validation rules

To display a list of valid parameters, your API methods accepts, this package uses Laravels Form Requests Validation.

public function rules()
{
    return [
        'title' => 'required|max:255',
        'body' => 'required',
        'type' => 'in:foo,bar',
        'thumbnail' => 'required_if:type,foo|image',
    ];
}

Result:

API responses

If your API route accepts a GET method, this package tries to call the API route with all middleware disabled to fetch an example API response.

If your API needs an authenticated user, you can use the actAsUserId option to specify a user ID that will be used for making these API calls:

$ php artisan api:generate --routePrefix="api/*" --actAsUserId=1

If you don't want to automatically perform API response calls, use the noResponseCalls option.

$ php artisan api:generate --routePrefix="api/*" --noResponseCalls

Note: The example API responses work best with seeded data.

Postman collections

The generator automatically creates a Postman collection file, which you can import to use within your Postman App for even simpler API testing and usage.

If you don't want to create a Postman collection, use the --noPostmanCollection option, when generating the API documentation.

Modify the generated documentation

If you want to modify the content of your generated documentation, go ahead and edit the generated index.md file. The default location of this file is: public/docs/source/index.md.

After editing the markdown file, use the api:update command to rebuild your documentation as a static HTML file.

$ php artisan api:update

As an optional parameter, you can use --location to tell the update command where your documentation can be found.

Skip single routes

If you want to skip a single route from a list of routes that match a given prefix, you can use the @hideFromAPIDocumentation tag on the Controller method you do not want to document.

Further modification

This package uses Documentarian to generate the API documentation. If you want to modify the CSS files of your documentation, or simply want to learn more about what is possible, take a look at the Documentarian guide.
