RESTful API Doc using SLIM and SWAGGER?

I think you are looking for this project: zircote/swagger-php

Here you'll find how to generate the doc on user request to a URL.

Basically you have to annotate your code with the Swagger Annotations, then create another route in Slim with a code similar to this:

<?phpuse Swagger\Swagger;$swagger = new Swagger('/project/root/top_level');header("Content-Type: application/json")echo $swagger->getResource('/pet', array('output' => 'json'));

And it will generate the Swagger API docs on the fly for you.

A short update to the answer of adosaiguas:

When using Slim Framework 4.0 and zircote/swagger-phpone can provide an api endpoint providing the swagger / OpenAPI 3.0 json description using the following code:

use function OpenApi\scan; /** * @OA\Get( *     path="/openapi", *     tags={"documentation"}, *     summary="OpenAPI JSON File that describes the API", *     @OA\Response(response="200", description="OpenAPI Description File"), * ) */$app->get('/openapi', function ($request, $response, $args) {    $swagger = scan('--PATH TO PROJECT ROOT--');    $response->getBody()->write(json_encode($swagger));    return $response->withHeader('Content-Type', 'application/json');});
