Download the PHP package jenky/hades without Composer

Hades

Dealing with errors when building an API can be a pain. Instead of manually building error responses you can simply throw an exception and the Hades will handle the response for you.

Installation

You may use Composer to install this package into your Laravel project:

After installing Hades, add the trait HandlesExceptionResponse to your app/Exceptions/Handler and Hades will automatically catches the thrown exception and will convert it into its JSON representation.

Configuration

Generic Error Response Format

By default all thrown exceptions will be transformed to the following format:

The debug information only available when application is not in production environment and debug mode is on.

Example:

Any keys that aren't replaced with corresponding values will be removed from the final response.

If you would like to use different error format for your application, you should call the Hades::errorFormat() method in the boot method of your App\Providers\AppServiceProvider class:

Formatting Exception Response

Customizing Exception Response

Sometimes you can't control how exception is thrown such as exception from Laravel framework or other third party packages. Laravel 8 introduces Renderable exception, however you need to build the response manually which might lead to inconsistent error format.

Hades allows you to register custom closures to replace all the values in the response format. You may accomplish this via the catch method of your app\Exceptions\Handler, Laravel will deduce what type of exception the closure renders by examining the type-hint of the closure:

Prior to Laravel 8, register had not been available in the app\Exceptions\Handler yet. However you can implement the method yourself:

If you don't want to modify the exception handler, you may wish to register the exception callback in your service provider. Typically, you should call this method from the boot method of your application's App\Providers\AppServiceProvider class:

Content negotiation

Forcing the JSON Response

By default, Laravel expects the request should contains header Accept with the MIME type application/json or custom MIME with json format such as application/vnd.myapp.v1+json in order to return JSON response. Otherwise your may get redirected to login page if the credentials are invalid or missing/passing invalid authorization token.

While this is a good design practice, sometimes you may wish to attach the header to request automatically, such as using Laravel as pure API backend. To do this, you should call the Hades::forceJsonOutput() method within the boot method of your App\Providers\AppServiceProvider.

Hades will add the header Accept: application/json to all incoming API requests. If you want to use custom MIME type, you may use the withMimeType to specify the MIME type:

Identify API Requests

In order to force the response to return JSON output, Hades needs to identify the incoming request so it doesn't add the Accept header on your normal HTML pages.

By default, all your API routes defined in routes/api.php have /api URI prefix automatically applied. Hades will inspects the incoming request URI and determines it's URI matches the /api prefix.

To customize this behavior, you may pass the closure to Hades::forceJsonOutput() to instruct Hades how to identify the incoming request:
