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/Sluggable

This 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 models
LogsActivity – track user actions
ApiResponse – 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?
