Stop Copy-Pasting Code! Learn How to Use Traits in Laravel the Right Way
July 1, 2025🚫 Stop Copy-Pasting Code!
Ever duplicated slug logic or logging across multiple models? Laravel's Traits got your back.
1. What’s a Trait?
A Trait is a snippet of reusable methods you can “mix into” any class.
trait Sluggable {
public function createSlug(string $text): string {
return \Illuminate\Support\Str::slug($text, '-');
}
}2. How to create one
Use Artisan:
php artisan make:trait Traits/SluggableThis creates app/Traits/Sluggable.php with the code above.
3. Use it in a model
namespace App\Models;
use App\Traits\Sluggable;
use Illuminate\Database\Eloquent\Model;
class Product extends Model {
use Sluggable;
protected static function booted() {
static::creating(fn($p) => $p->slug = $p->createSlug($p->name));
}
}4. When to use Traits
- ✅ Shared logic across many classes
- ✅ You want DRY code without complex inheritance
5. Real-world examples
HasUuid– auto-fill UUID on modelsLogsActivity– track user actionsApiResponse– uniform JSON responses
6. When not to use Traits
- ❌ Complex logic needing DI
- ❌ Too many unrelated methods grouped
- ❌ Only used by a single class
- ❌ Core business logic – better in Services
Conclusion
Traits are a powerful tool for reusable, maintainable code—if used wisely. Next time you're about to copy-paste, ask: can I make this a Trait?
