README

All in one solution for exception for JSON REST APIs on Laravel and Lumen.

About

The goal of this package is to provide you with a set of most common exceptions that may be needed while developing JSON REST API. It also:

• Handles exceptions output.
• Handles exceptions report to logs.
• Overwrites default Validator to make validation errors more verbose.
• Has a FormRequest that to handle validation errors and pass them to ApiExceptions layer.

Installation

PHP 5.4+ or HHVM 3.3+, Composer and Laravel 5.1+ are required.

To get the latest version of Laravel Laravel-API-Debugger, simply add the following line to the require block of your composer.json file.

For Laravel 5.1

"lanin/laravel-api-exceptions": "^0.1.0"

For Laravel 5.3

"lanin/laravel-api-exceptions": "^1.0.0"

You'll then need to run composer install or composer update to download it and have the autoloader updated.

Once Laravel-API-Exceptions is installed, if you're using Laravel 5.1, 5.2, 5.3, and 5.4, you need to register the service provider. Open up config/app.php and add the following to the providers key.

Lanin\Laravel\ApiExceptions\ApiExceptionsServiceProvider::class,

If you're using Laravel 5.5, you don't need to add anything in config/app.php. It will use package auto discovery feature in Laravel 5.5.

Exceptions

Every ApiException can be thrown as a normal exception and they will be automatically serialized to JSON with corresponding HTTP status, if user wants json:

{
    "id": "not_found",
    "message": "Requested object not found."
}

This object will be also populated with trace info, when APP_DEBUG is true.

Also it can have meta attribute when there is additional info. For example for validation errors:

{
	"id": "validation_failed",
	"message": "Validation failed.",
	"meta": {
		"errors": {
			"tags": [{
				"rule": "max.array",
				"message": "The tags may not have more than 10 items.",
				"parameters": ["10"]
			}]
		}
	}
}

For ValidationApiException, meta attribute has errors object that contains validations errors. Every attribute of this object is a name of a request parameter to validate to and value is an array of errors with description.

Customization

You can customize errors APU response by overriding formatApiResponse method in your ExceptionsHandler.

For example if you want to put everything under error attribute, you can do it like this:

/**
 * Format error message for API response.
 *
 * @param  ApiException  $exception
 * @return mixed
 */
protected function formatApiResponse(ApiException $exception)
{
    return [
        'error' => $exception->toArray(),
    ];
}

Handler

Extend your default exceptions handler with:

• \Lanin\Laravel\ApiExceptions\LaravelExceptionHandler for Laravel
• \Lanin\Laravel\ApiExceptions\LumenExceptionHandler for Lumen

And remove everything else. Example:

<?php

namespace App\Exceptions;

use Lanin\Laravel\ApiExceptions\LaravelExceptionHandler;

class Handler extends LaravelExceptionHandler
{

}

FormRequest

To use FormRequest extend all your Request classes with \Lanin\Laravel\ApiExceptions\Support\Request. It will automatically support validation errors and pass them to the output.

It also has a very handy helper method validatedOnly() that returns from request only those items that are registered in rules method.
