README

A lightweight Laravel package that provides standardized JSON response handling and HTTP status code constants for modern API development.

Features

• ResponseHelperTrait: Unified interface for success and error responses with consistent JSON formatting
• ApiCodes: Comprehensive HTTP status code constants (1xx, 2xx, 3xx, 4xx, 5xx)
• JSON Response Builder Integration: Built on top of the marcin-orlowski/response-builder package for flexible response construction
• Type-safe Status Codes: Named constants for all standard HTTP status codes (e.g., ApiCodes::OK, ApiCodes::NOT_FOUND)
• Flexible Data & Messaging: Support for custom data, error objects, and messages in responses

Installation

1. Via Composer (when package is published):

   composer require redoy/core-module

2. Local Development:

   # Clone or link the package into packages/Redoy/CoreModule
   composer dump-autoload

3. Register Service Provider (Auto-registered, but manual if needed):

   php artisan package:discover

4. Publish Package Assets (Configuration & Language Files):

   php artisan vendor:publish --provider="Redoy\CoreModule\Providers\CoreModuleServiceProvider"

   This will publish:

   • Configuration: config/core.php, config/response_builder.php
   • Language Files: resources/lang/en/api.php, resources/lang/bn/api.php

5. Optional - Publish Only Configuration:

   php artisan vendor:publish --provider="Redoy\CoreModule\Providers\CoreModuleServiceProvider" --tag="config"

6. Optional - Publish Only Language Files:

   php artisan vendor:publish --provider="Redoy\CoreModule\Providers\CoreModuleServiceProvider" --tag="lang"

Quick Start

Using ResponseHelperTrait

Add the trait to any class (Controller, Service, etc.):

<?php
namespace App\Http\Controllers;

use Redoy\CoreModule\Traits\ResponseHelperTrait;
use Redoy\CoreModule\Constants\ApiCodes;

class UserController extends Controller
{
    use ResponseHelperTrait;

    public function index()
    {
        $users = User::all();
        return $this->successResponse($users, ApiCodes::OK, 'Users retrieved successfully');
    }

    public function store(Request $request)
    {
        $user = User::create($request->validated());
        return $this->successResponse($user, ApiCodes::CREATED, 'User created successfully');
    }

    public function destroy($id)
    {
        try {
            User::findOrFail($id)->delete();
            return $this->successResponse(null, ApiCodes::NO_CONTENT, 'User deleted');
        } catch (\Exception $e) {
            return $this->errorResponse(
                ['error' => 'User not found'],
                ApiCodes::NOT_FOUND,
                'Failed to delete user'
            );
        }
    }
}

Using ApiCodes

Reference any HTTP status code via named constants:

use Redoy\CoreModule\Constants\ApiCodes;

// 2xx Success codes
ApiCodes::OK;                      // 200
ApiCodes::CREATED;                 // 201
ApiCodes::ACCEPTED;                // 202
ApiCodes::NO_CONTENT;              // 204

// 4xx Client error codes
ApiCodes::BAD_REQUEST;             // 400
ApiCodes::UNAUTHORIZED;            // 401
ApiCodes::FORBIDDEN;               // 403
ApiCodes::NOT_FOUND;               // 404
ApiCodes::UNPROCESSABLE_ENTITY;    // 422

// 5xx Server error codes
ApiCodes::INTERNAL_SERVER_ERROR;   // 500
ApiCodes::SERVICE_UNAVAILABLE;     // 503

// View all codes as array
ApiCodes::HTTP_STATUS_CODES;       // Array of all status codes

• JSON-Driven Tests: 20 comprehensive test cases covering:
  • Valid success and error responses

Overall: 35 tests with 129 assertions, all passing ✓

Common Response Patterns

Success Response

return $this->successResponse($data, ApiCodes::OK, 'Operation successful');

Error Response

return $this->errorResponse($errors, ApiCodes::BAD_REQUEST, 'Validation failed');

No Content (204)

return $this->successResponse(null, ApiCodes::NO_CONTENT, 'Deleted');

Created Resource (201)

return $this->successResponse($resource, ApiCodes::CREATED, 'Resource created');
