Laravel Selective Response

Automatic API resource filtering based on model select() queries with optional Scramble documentation support.

Features

• Automatic Filtering: Automatically filters API resource responses based on select() queries
• Zero Breaking Changes: Just change your resource parent class - no code changes needed
• Scramble Integration: Optional extension that updates API documentation to show only selected fields
• Flexible Configuration: Enable/disable globally or per-resource
• Always-Include Fields: Support for fields that should always be included
• Relationship Support: Works seamlessly with whenLoaded() pattern

Installation

composer require mustafafares/laravel-selective-response

Publish the configuration file:

php artisan vendor:publish --tag=selective-response-config

Quick Start

1. Update Your Resources

Change your resources to extend BaseApiResource instead of JsonResource:

<?php

namespace App\Http\Resources;

use MustafaFares\SelectiveResponse\Http\Resources\BaseApiResource;

class UserResource extends BaseApiResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'phone' => $this->phone,
            'address' => $this->address,
        ];
    }
}

2. Use in Controllers

<?php

namespace App\Http\Controllers\Api;

use App\Http\Resources\UserResource;
use App\Models\User;

class UserController extends Controller
{
    // Full response - returns all fields
    public function show($id)
    {
        $user = User::findOrFail($id);
        return new UserResource($user);
    }

    // Selective response - returns only selected fields
    public function summary($id)
    {
        $user = User::select('id', 'name', 'email')->findOrFail($id);
        return new UserResource($user);
        // Returns: {id, name, email} ✨
    }
}

That's it! The filtering happens automatically.

Usage Examples

Basic Usage

// Resource (no changes needed!)
class UserResource extends BaseApiResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'phone' => $this->phone,
        ];
    }
}

// Controller - Full response
$user = User::find($id);
return new UserResource($user);
// Returns: {id, name, email, phone}

// Controller - Selective response
$user = User::select('id', 'name')->find($id);
return new UserResource($user);
// Returns: {id, name}  ✨ Automatic!

Always Include Fields

class UserResource extends BaseApiResource
{
    protected $alwaysInclude = ['id'];

    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
        ];
    }
}

// Even with select('name'), 'id' is always included
User::select('name')->find($id);
// Returns: {id, name}

Disable Filtering

// Option 1: In resource class
class AdminResource extends BaseApiResource
{
    protected $useSelectiveResponse = false;
}

// Option 2: In controller
return (new UserResource($user))->withoutSelectiveFiltering();

With Relationships

class UserResource extends BaseApiResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'posts' => PostResource::collection($this->whenLoaded('posts')),
        ];
    }
}

// Load relationship
User::select('id', 'name')->with('posts')->find($id);
// Returns: {id, name, posts: [...]}

Dynamic Always-Include

public function summary($id)
{
    $user = User::select('name')->findOrFail($id);
    return (new UserResource($user))
        ->alwaysInclude(['id', 'created_at']);
}

Scramble Extension

The package includes an optional extension for Scramble that automatically detects select() calls in your controllers and updates the API documentation to show only selected fields.

Setup

1. Install Scramble (if not already installed):

composer require dedoc/scramble

2. Install PHP Parser (required for the extension):

composer require nikic/php-parser

3. Publish Scramble config (if not already done):

php artisan vendor:publish --tag=scramble-config

4. Register the extension in config/scramble.php:

<?php

return [
    // ... other config ...

    'extensions' => [
        \MustafaFares\SelectiveResponse\Extensions\SelectiveResponseExtension::class,
    ],
];

How It Works

The extension uses PHP Parser to analyze your controller methods and find select() calls. It then filters the OpenAPI schema to show only the selected fields in the documentation.

Before Extension:

// Controller
$user = User::select('id', 'name', 'email')->findOrFail($id);
return new UserResource($user);

// Scramble docs show: {id, name, email, phone, address, ...} ❌

After Extension:

// Same controller code
$user = User::select('id', 'name', 'email')->findOrFail($id);
return new UserResource($user);

// Scramble docs show: {id, name, email} ✅

Disable Scramble Extension

You can disable the Scramble extension in the config:

// config/selective-response.php
'scramble' => [
    'enabled' => false,
],

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=selective-response-config

Available Options

<?php

return [
    // Enable/disable selective filtering globally
    'enabled' => env('SELECTIVE_RESPONSE_ENABLED', true),

    // Fields that should always be included globally
    'always_include' => [
        // 'id',
    ],

    // Scramble extension configuration
    'scramble' => [
        'enabled' => env('SELECTIVE_RESPONSE_SCRAMBLE_ENABLED', true),

        'always_include_in_docs' => [
            // 'id',
        ],
    ],
];

Common Patterns

List Endpoint (Efficient)

public function index()
{
    $users = User::select('id', 'name', 'email')
        ->paginate(20);
    return UserResource::collection($users);
}

Detail Endpoint (Full Data)

public function show($id)
{
    $user = User::with('posts', 'role')->findOrFail($id);
    return new UserResource($user);
}

Search with Dynamic Fields

public function search(Request $request)
{
    $fields = explode(',', $request->input('fields', 'id,name,email'));
    $users = User::select($fields)
        ->where('name', 'like', "%{$request->q}%")
        ->get();
    return UserResource::collection($users);
}

Force Full Response

public function adminView($id)
{
    $user = User::select('id')->findOrFail($id);
    return (new UserResource($user))->withoutSelectiveFiltering();
}

Advanced Features

Custom Always-Include Logic

class UserResource extends BaseApiResource
{
    protected function shouldIncludeKey(string $key, $value): bool
    {
        // Always include timestamps
        if (in_array($key, ['created_at', 'updated_at'])) {
            return true;
        }

        return parent::shouldIncludeKey($key, $value);
    }
}

Conditional Computed Fields

public function toArray($request)
{
    return [
        'id' => $this->id,
        'name' => $this->name,
        'full_name' => $this->whenAttributeLoaded('name', 
            $this->first_name . ' ' . $this->last_name
        ),
    ];
}

Testing

use MustafaFares\SelectiveResponse\Http\Resources\BaseApiResource;
use Tests\TestCase;
use App\Models\User;

class SelectiveResponseTest extends TestCase
{
    public function test_selective_response()
    {
        $user = User::factory()->create();
        $selected = User::select('id', 'name')->find($user->id);
        $resource = new UserResource($selected);
        $data = $resource->toArray(request());

        $this->assertArrayHasKey('id', $data);
        $this->assertArrayHasKey('name', $data);
        $this->assertArrayNotHasKey('email', $data);
    }
}

Troubleshooting

Issue: All fields still returned

Solution: Verify you're extending BaseApiResource, not JsonResource

Issue: Relationships not working

Solution: Use $this->whenLoaded() for relationships

Issue: Computed fields missing

Solution: Use $this->whenAttributeLoaded() for computed fields

Issue: Need specific field always

Solution: Add to protected $alwaysInclude = ['field']; in your resource

Issue: Scramble extension not working

Solutions:

1. Clear config cache: php artisan config:clear
2. Verify extension is in config/scramble.php
3. Check PHP Parser is installed: composer show nikic/php-parser
4. Ensure Scramble is installed: composer show dedoc/scramble

Performance Benefits

| Endpoint | Without Select | With Select | Improvement | |----------|---------------|-------------|-------------| | User list | 50 KB | 10 KB | 80% smaller | | Search | 100 KB | 20 KB | 80% smaller | | Summary | 2 KB | 0.5 KB | 75% smaller |

Result: Faster APIs, lower bandwidth costs, better UX!

Migration Guide

From JsonResource to BaseApiResource

1. Change the parent class:

// Before
class UserResource extends JsonResource

// After
class UserResource extends BaseApiResource

2. Add the import:

use MustafaFares\SelectiveResponse\Http\Resources\BaseApiResource;

3. That's it! Your toArray() method works exactly the same.

Requirements

• PHP 8.1+
• Laravel 10.0+, 11.0+, or 12.0+
• (Optional) Scramble 1.0+ for documentation extension
• (Optional) PHP Parser 5.0+ for Scramble extension
