Shield Laravel Package

Getting Started

Start by confirming the package is installable in your Laravel version. artesaos/shield last shipped in 2016, so check its composer.json constraints before adding it to a real application. Use a scratch app or disposable branch first.

Minimal steps:

composer require artesaos/shield

# Publish config and migrations. Confirm the provider class from the package source.
php artisan vendor:publish --provider="Artesaos\Shield\ShieldServiceProvider"

php artisan migrate

Add the package trait to your authenticatable model:

use Artesaos\Shield\Traits\HasRoles; // verify exact namespace in vendor/artesaos/shield

class User extends Authenticatable
{
    use HasRoles;
}

Where to look first:

1. config/shield.php — table names, model bindings, guard behaviour.
2. database/migrations/ — role/permission pivot tables and foreign keys.
3. src/ShieldServiceProvider.php — facade alias, middleware aliases, Blade directives, bindings.
4. The facade class and traits — confirm actual method names; the README may be thinner than the source.

First use case: protect an admin route with a role.

// Seeder or tinker
$admin = Shield::createRole('admin');          // verify method name
$admin->givePermission('manage-users');        // verify method name

$user->assignRole('admin');                    // verify method name

Register the middleware alias if the package does not do it automatically:

// app/Http/Kernel.php
protected $routeMiddleware = [
    // ...
    'role' => \Artesaos\Shield\Middleware\RoleMiddleware::class,
    'permission' => \Artesaos\Shield\Middleware\PermissionMiddleware::class,
];

Route::group(['middleware' => ['role:admin']], function () {
    Route::get('/admin', AdminController::class . '@index');
});

Implementation Patterns

Treat roles as coarse job functions and permissions as fine-grained abilities. Seed both deterministically so every environment has the same canonical names.

// database/seeders/ShieldSeeder.php
Shield::createRole('admin');
Shield::createRole('editor');

Shield::createPermission('manage-users');
Shield::createPermission('edit-posts');
Shield::createPermission('publish-posts');

Shield::role('admin')->givePermission('manage-users');
Shield::role('editor')->givePermission('edit-posts');

Use the package API rather than direct pivot-table writes so caches and events stay consistent.

Assign roles through the user model:

$user->assignRole('editor');
$user->removeRole('editor');

Check access at the right layer:

// Route-level: middleware
Route::middleware('permission:edit-posts')->group(function () {
    Route::put('/posts/{post}', [PostController::class, 'update']);
});

// Controller-level: explicit authorization
public function update(Request $request, Post $post)
{
    abort_unless($request->user()->hasPermission('edit-posts'), 403);
    // ...
}

// Blade: presentation only
@role('admin')
    <a href="/admin">Admin</a>
@endrole

@permission('edit-posts')
    <a href="{{ route('posts.edit', $post) }}">Edit</a>
@endpermission

If the package registers permissions as gates, you can use Laravel’s native authorization:

// AuthServiceProvider
Gate::define('edit-posts', function ($user) {
    return $user->hasPermission('edit-posts');
});

// Controller
$this->authorize('edit-posts');

// Blade
@can('edit-posts')
    ...
@endcan

For policies, keep the package check inside the policy method so authorization remains centralised:

public function update(User $user, Post $post)
{
    return $user->hasPermission('edit-posts')
        && $post->author_id === $user->id;
}

Add a super-admin bypass once, not in every policy:

Gate::before(function ($user) {
    return $user->hasRole('super-admin') ? true : null;
});

Use eager loading when listing many users or rendering a permission-heavy page:

$users = User::with('roles.permissions')->paginate();

For route groups, prefer middleware over scattered checks:

Route::middleware(['auth', 'role:admin|super-admin'])->group(function () {
    // admin area
});

Gotchas and Tips

• Age is the main risk. The package’s last release was 2016. It likely targets Laravel 5.x and older PHP versions. Do not assume it works on Laravel 9/10/11 or PHP 8.x without checking composer.json and running the migration and middleware paths end to end.
• Unmaintained authorization code is security-sensitive. Auditing roles and permissions is not like auditing a view helper. If the package is abandoned, prefer Laravel’s Gate/Policy system or an actively maintained alternative such as spatie/laravel-permission.
• Confirm the actual API before writing seeders. The package description promises a fluent API, Blade directives, and middleware, but the exact method names and directive syntax must be read from src/. Do not copy examples blindly.
• Publish migrations before running them. Check for table-name collisions with existing roles, permissions, or pivot tables. Rename tables in config and migrations if needed.
• Check the down() path. If the package owns tables, you need a safe rollback plan. Foreign-key constraints on pivot tables should be deliberate, especially for role deletion.
• Guard mismatch. Roles and permissions are often tied to the default guard. If you use multiple guards (admin, api), verify that checks use the correct user and guard. A passing $user->hasRole() on the web guard does not automatically authorize an API guard user.
• Permission caching can go stale. If the package caches roles or permissions, changing a role may not take effect until the cache is cleared. In long-running workers such as Octane, request-scoped state and caches need explicit review.
• N+1 queries in loops. $user->hasPermission() inside a Blade loop or API resource can query repeatedly. Eager load roles.permissions and cache per-request results if the package does not.
• Blade directives are not enforcement. @role and @permission hide UI; they do not protect routes or actions. Always enforce with middleware, authorize(), or a policy.
• Facade and helper collisions. A global Shield alias or helper function can collide with your own code. Rename the alias in config/app.php if necessary.
• Direct DB writes bypass package behaviour. Updating pivot tables manually may skip cache invalidation or events. Use the package’s assignment methods.
• Config cache. After changing config/shield.php, run php artisan config:clear. If the package reads config during boot, a cached config can mask changes.
• Debugging checks. Dump $user->roles, the exact permission string, and the guard. Permission names are case- and whitespace-sensitive. Verify middleware aliases with php artisan route:list.
• Testing. Use RefreshDatabase, seed the roles and permissions your test needs, and assert both the happy path and the 403 path. Test middleware and policy paths separately.
• Extension points. The description mentions configurable tables and models. If you need custom behaviour, publish the config, bind your own Role/Permission models, and extend the package models rather than editing vendor files. Keep the integration surface narrow so replacing the package later is feasible.
