Simple Difference Between Events and Observers
Observers are basically predefined events that happen only on Eloquent Models (creating a record, updating a record, deleting, etc). Events are generic, aren’t predefined, and can be used anywhere, not just in models.
01 Why Observers Used in Laravel?
An observer watches for specific things that happen within eloquent such as saving, saved, deleting, deleted (there are more but you should get the point). Observers specifically bound to a model.
02 Why Events Used in Laravel?
Events are actions that are driven by whatever the programmer wants. If you want to fire an event when somebody loads a page, you can do that. Events can also be a queue and ran via Laravel’s cron job.
The programmer can define Events effectively. Events give you the ability to handle actions that you would not want a user to wait for (an example being the purchase of podcasts).
