Membrane-Laravel

Integrates Membrane-core with Laravel.

About

Middleware that validates the raw user input from incoming HTTP requests against your OpenAPI spec.
Adds a Membrane\Result\Result onto your Illuminate\Contracts\Container\Container.
The Result object contains the cleaned up data and additional details in the case of invalid requests.

Setup

Installation

Require the membrane/laravel package in your composer.json and update your dependencies:

composer require membrane/laravel

Configuration

The defaults are set in config/membrane.php.
To publish a copy to your own config, use the following:

php artisan vendor:publish --tag="membrane"

API Spec File

This is the absolute filepath of your OpenAPI.

By default, it looks for <your-project-directory>/api/openapi.yaml.

Validation Error Response Code

Set 'validation_error_response_code' to the integer value of the default http status code for invalid results.

Validation Error Response Type

Set 'validation_error_response_type' to the string value of the default response type for API problems.

API Problem Response Types

Within the 'api_problem_response_types' array: Set integer http status code => string response type pairs.
These are more specific and will override the default value set by 'validation_error_response_type'

Usage

Requests

The \Membrane\Laravel\Middleware\RequestValidation middleware will validate or invalidate incoming requests and let you decide how to react. You can follow it with your own custom middleware or with one of the following built-in options to produce an error response:

Responses

Any response middleware MUST follow the RequestValidation middleware as it requires the result object being added to your container.
These middlewares will check whether the request has passed or failed validation.
Invalid requests will return an appropriate response detailing the reasons the request was invalid.

Your response can be in one of the following formats.

Flat Json

\Membrane\Laravel\Middleware\ResponseJsonFlat

{
    "errors":{
        "pet->id":["must be an integer"],
        "pet":["name is a required field"]
    },
    "title":"Request payload failed validation",
    "type":"about:blank",
    "status":400
}

Nested Json

\Membrane\Laravel\Middleware\ResponseJsonNested

{
    "errors":{
        "errors":[],
        "fields":{
            "pet":{
                "errors":[
                    "name is a required field"
                ],
                "fields":{
                    "id":{
                        "errors":[
                            "must be an integer"
                        ],
                        "fields":[]
                    }
                }
            }
        }
    },
    "title":"Request payload failed validation",
    "type":"about:blank",
    "status":400
}

Global Usage

To use any of the above middlewares on all routes, go into your app/Http/Kernel.php and add them to your middleware array.

For example:

protected $middleware = [
  \Membrane\Laravel\Middleware\RequestValidation::class,
  \Membrane\Laravel\Middleware\ResponseJsonFlat::class
  // ...
];
