README

A lightweight Laravel package for standardized JSON API responses, validation, and error logging.
Perfect for building clean, consistent REST APIs without repeating boilerplate code.

☕ Support Me

If you find this package helpful, consider supporting my work:

🚀 Features

• ✅ Consistent JSON responses (success, error, validationError)
• ✅ Built-in validation helpers with structured error output
• ✅ Automatic error logging with unique trace_id for easier debugging
• ✅ Extensible BaseController and BaseException
• ✅ Publishable traits and base classes for full customization
• ✅ Configuration publishing for easy overrides

📦 Installation

Require the package via Composer:

composer require xetreon/jsonresponse

Publish the config file to customize defaults:

php artisan vendor:publish --tag=config

🧩 Usage Example

Here’s how you can use Xetreon\JsonResponse\Controllers\BaseController in your controllers.

use Xetreon\JsonResponse\Controllers\BaseController;
use Illuminate\Http\Request;
use App\Models\User;

class UserController extends BaseController
{
    public function index(Request $request)
    {
        $users = User::query();

        // fetchFromQuery automatically applies:
        // - status filtering (status[])
        // - sorting (sort_by & sort_order)
        // - pagination (per_page)
        return $this->fetchFromQuery($users, $request->all());
    }

    public function show($id)
    {
        return $this->fetchById(User::query(), $id, 'User not found');
    }
}

📥 Sample Request JSON

{
  "status": ["active", "pending"],  // Filter results by status (uses whereIn)
  "sort_by": "created_at",          // Sort field
  "sort_order": "DESC",             // Sorting direction (ASC or DESC)
  "per_page": 15                    // Pagination size
}

🖥 Example cURL Request

curl --location 'https://your-app.test/api/users' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data '{
    "status": ["active", "pending"],
    "sort_by": "created_at",
    "sort_order": "DESC",
    "per_page": 15
}'

⚡ Direct Usage of Response Methods

You can use the built-in response helper methods in your controllers for quick and consistent JSON responses.

✅ Success Response

return $this->success(true, ['foo' => 'bar'], 'Operation successful');

return $this->error(false, [], 'Something went wrong', 500);

🛡️ Validation Helper

Use the built-in validate() method for consistent request validation and error responses.

Example Usage

$result = $this->validate($request->all(), [
    'email' => 'required|email',
    'password' => 'required|min:8',
]);

if (!$result['result']) {
    return $this->validationError($result);
}

🛠 Publishing Base Classes and Traits

You can publish the BaseController and BaseException into your application for customization.

🎛 Publish Classes

php artisan vendor:publish --tag=classes

🎛 Publishing Traits

php artisan vendor:publish --tag=xetreon-jsonresponse-traits

📝 Using the LoggerTrait

The LoggerTrait provides an easy way to log info, warning, and error messages with consistent formatting and automatic file/line code references.

1️⃣ Importing & Using the Trait

use Xetreon\JsonResponse\Traits\LoggerTrait;

class OrderService
{
    use LoggerTrait;

    public function processOrder($order)
    {
        // Log an informational message
        $this->createLog('Starting order processing', ['order_id' => $order->id]);

        try {
            // Your order processing logic...
        } catch (\Throwable $e) {
            // Log an error with context
            $this->createErrorLog('Order processing failed', [
                'order_id' => $order->id,
                'exception' => $e->getMessage()
            ]);
        }
    }
}

2️⃣ Available Methods

Parameter Details:

• $message → A short, human-readable message.
• $context → Additional data to log (automatically JSON-encoded).
• $trace → (Optional) Stack trace depth — 1 for current method, 2 for caller, etc.

3️⃣ Output Example (Log File)

When logging using LoggerTrait, you get standardized log entries:

[2025-09-14 15:30:12] local.INFO: APP_COMMON - Starting order processing {"order_id":123}
[2025-09-14 15:30:13] local.ERROR: APP_COMMON - Order processing failed {"order_id":123,"exception":"Insufficient stock"}

4️⃣ Customizing the Log Channel

You can configure which channel LoggerTrait writes to by editing config/xetreon-jsonresponse.php:

'log_channel' => env('XETREON_JSON_LOG_CHANNEL', config('logging.default')),

Or overwrite via .env

XETREON_JSON_LOG_CHANNEL=stack

5️⃣ Using Class Codes

You can map specific files to short class codes for more meaningful log identifiers.

Example Configuration (config/xetreon-jsonresponse.php)

'classcode' => [
    'app/Services/OrderService.php' => 'ORD',
    'app/Http/Controllers/UserController.php' => 'USR',
],

✅ Example Log Output

[2025-09-14 15:30:12] local.INFO: ORD:123 - Starting order processing {"order_id":123}

Here you will get the controller code : line number in the log.

✅ Why Use LoggerTrait?

• Consistent: Ensures the same log format across the entire application.
• Traceable: Automatically adds file name and line number to every log entry.
• Configurable: Lets you choose the log channel per environment.
• Structured: Always logs with JSON-encoded context for easy parsing and analysis.

⚠️ Exception Usage

You can throw a BaseException anywhere in your application code to return a standardized JSON error response.

💻 Example

use Xetreon\JsonResponse\Exceptions\BaseException;

throw new BaseException('Something went wrong', 500, ['context' => 'extra-data']);

📤 Example JSON Response

{
  "result": false,
  "data": {
    "context": "extra-data"
  },
  "message": "Something went wrong",
  "status_code": 500,
  "error": {
    "type": "BaseException",
    "file": "app/Services/OrderService.php",
    "line": 42,
    "time": "2025-09-14 16:00:00",
    "code": "APP_COMMON"
  }
}

✅ Highlights

• file & line – Useful in local/dev environments (hidden in production for security).
• code – Class code or module identifier for quick filtering in logs.
• time – Exact timestamp when the exception was thrown.

⚠️ Extending BaseException

You can create custom exceptions that extend BaseException for different error scenarios.

💻 Example

<?php

namespace App\Exceptions;

use Xetreon\JsonResponse\Exceptions\BaseException;

class AuthException extends BaseException
{
    public function __construct(string $message = 'Unable to Authenticate User', int $code = 401)
    {
        parent::__construct($message, $code);
    }
}

📤 Example Usage

use App\Exceptions\AuthException;

throw new AuthException();

⚠️ Adding Extra Data

You can pass extra data to the exception for better debugging and context.

💻 Example

throw new AuthException('Token is invalid', 401, [
    'token' => $request->bearerToken(),
    'ip' => $request->ip()
]);

4️⃣ Class Codes (Optional)

You can define file-specific codes in config/xetreon-jsonresponse.php to make error codes more meaningful:

'classcode' => [
    'app/Exceptions/AuthException.php' => 'AUTH',
    'app/Services/OrderService.php' => 'ORD'
],

Now your error JSON will include:

"code": "AUTH:23"

Where 23 is the line number where the exception occurred.

✅ Benefits

• 🔥 Consistent error format — no more HTML errors in API responses.
• 🧠 Developer-friendly — automatically adds trace_id, file, line, and time.
• 🛠 Extensible — easily create your own custom exception classes.
• 📊 Debuggable — logs all exceptions automatically for post-mortem analysis.
