Laravel API Exceptions

A small library of reusable API exception classes for Laravel apps. Each exception implements Responsable, so throwing one returns a JSON error response with an appropriate HTTP status code.

Requirements

• PHP ^8.2
• Laravel 11.x, 12.x or 13.x

Install

composer require hatchyu/laravel-api-exceptions

The service provider is auto-discovered by Laravel.

Usage

use Hatchyu\ApiExceptions\Http\BadRequestException;

// Returns a 400 JSON response:
// { "error": { "message": "Invalid payload." } }
throw new BadRequestException('Invalid payload.');

If you omit a message, a default is generated from the class name, for example BadRequestException becomes "Bad request.".

Factory Helpers Some domain exceptions expose convenient factory methods for consistent messages:

use Hatchyu\ApiExceptions\General\FileTooLargeException;
use Hatchyu\ApiExceptions\General\FileUploadException;
use Hatchyu\ApiExceptions\General\UnsupportedFileTypeException;
use Hatchyu\ApiExceptions\Model\ModelNotFoundException;
use Hatchyu\ApiExceptions\Model\ModelCreateException;
use Hatchyu\ApiExceptions\Model\ModelUpdateException;
use Hatchyu\ApiExceptions\Model\ModelDeleteException;

throw FileTooLargeException::for('invoice.pdf');
throw FileUploadException::for('invoice.pdf');
throw UnsupportedFileTypeException::forFile('invoice.pdf', 'application/pdf');
throw ModelNotFoundException::forModel(Customer::class, 3);
throw ModelCreateException::forModel(Customer::class, 'Email already exists');
throw ModelUpdateException::forModel($customer);
throw ModelDeleteException::forModel($customer, 'Customer has active orders');

// Non-"id" primary keys are resolved automatically from the model instance.
// Example output: "Failed to update Order (order_id: ORD-1001)."
throw ModelUpdateException::forModel($order);

Note: DocumentUploadException is deprecated in favor of FileUploadException.
