OpenAPI PHP Attributes Generator

This CLI Tool is able to generate an OpenApi JSON file description according to PHP attributes contained in your files.

⚠️ Missing something ?

Just open an issue saying what's missing ! Feel free to open a PR but we recommend opening an issue beforehand.

Where to start ?

1 - Install the package openapi-php-attributes-generator with composer.

composer require uderline/openapi-php-attributes

2 - Describe your API by following this documentation: https://uderline.github.io/openapi-php-attributes/

3 - Generate the JSON file:

php ./vendor/bin/opag /src/files/project openapi.json

A new file called openapi.json has been generated !

Example

#[Controller]
class Controller {
    #[
        GET("/path/{id}", ["Tag1", "Tag2"], "Description of the method"),
        Property(Type::STRING, "prop1", description: "Property description", enum: BackedEnum::class),
        Property(Type::INT, "prop2", example: 1),
        Property(Type::BOOLEAN, "prop3"),
        Property(Type::REF, "prop4", ref: RefSchema::class)
        Response(ref: SchemaName::class, description: "Response description")
    ]
    public function get(#[Parameter("Parameter description")] int $id): JsonResponse {
        // ...
    }
}

enum BackedEnum: string
{
    case VAL1: "val1";
    case VAL2: "val2";
}

#[
    Schema,
    Property(Type::STRING, "Property 1"),
    Property(Type::INT, "Property 2"),
]
class RefSchema
{
    public string $property1;
    public int $property2;
}
