What is Laravel observer pattern and how is it implemented?

Updated May 16, 2026

Short answer

Observers listen to Eloquent model events like create, update, and delete.

Deep explanation

Laravel observers allow separation of model event logic into dedicated classes. They listen to lifecycle events such as creating, created, updating, and deleted. This keeps models clean and improves maintainability.

Real-world example

Used to automatically send emails after user registration.
