Usage

Laravel Auto Swagger Docs works based on recommended practices by Laravel. It will parse your routes and generate a path object for each one. If you inject Form Request classes in your controller's actions as request validation, it will also generate the parameters for each request that has them. For the parameters, it will take into account wether the request is a GET/HEAD/DELETE or a POST/PUT/PATCH request and make its best guess as to the type of parameter object it should generate. It will also generate the path parameters if your route contains them. Finally, this package will also scan any documentation you have in your action methods and add it as summary and description to that path, along with any appropriate annotations such as @deprecated.

One thing to note is this library leans on being explicit. It will choose to include keys even if they have a default. For example it chooses to say a route has a deprecated value of false rather than leaving it out. I believe this makes reading the documentation easier by not leaving important information out. The file can be easily cleaned up afterwards if the user chooses to leave out the defaults.

Command line

Generating the swagger documentation is easy, simply run php artisan swagger:generate in your project root. The output of the command will be stored in your storage path linked in config file.

If you wish to generate docs for a subset of your routes, you can pass a filter using --filter, for example: php artisan swagger:generate --filter="/api"

You can also configure your swagger.php file to always generate schema when accessing Swagger UI or just by adding this line in your .env: SWAGGER_GENERATE_ALWAYS=true

By default, laravel-swagger prints out the documentation in json format, if you want it in YAML format you can override the format using the --format flag. Make sure to have the yaml extension installed if you choose to do so.

Format options are:

• json
• yaml

Annotations syntax

The annotations are written in the PHPDoc block of your controller methods. The syntax is as follows:

The syntax is basically a JSON inside a comment block. Just be aware to follow strictly the JSON syntax.

Rules

• The key: value pairs must be separated by a column :
• The key: value pairs must be always in the same line. If you want a longer description, you can write it in the comment itself that this description will be used as the description of the route. You can see the example in the @Request() decorator.
• When you need to use an array, you can use the square brackets [] to define it as in JSON.

@Request() decorator

You can have only one @Request() decorator.

@Response() decorator

You can have multiple @Response decorators

• The code property is required and must be the first in property
• You can use the optional description property to describe your response
• You can use the optional ref property to refer a Model or a custom Schema, you can also add an [] in the final of the Schema name to refer an array of that Schema or use the full Schema path inside, finally you can use a schema builder

[!NOTE] You can see all available schema builder or create your own schema builder, explore swagger.schema_builders config for more information

Custom Validators

These validators are made purely for visual purposes, however, some of them can actually do validation. But where to insert it? You can simply insert it in the rules array in your Form Request class like a normal Laravel validation.

swagger_default

It sets the default value for the parameter in the documentation

swagger_example

It sets the example value for the parameter in the documentation

[!NOTE] The difference between swagger_default and swagger_example is that swagger_default will inform to the user that this value is the default value for this parameter inside the application. swagger_example will just illustrate an example of how the parameter should be filled.

swagger_description

It sets the description for the parameter in the documentation

swagger_min

swagger_max
