Event handlers play a big role in Sitecore to intercept events being executed. When any event is raised, it executes multiple event handlers sequentially, which is the same that a pipeline does with its processors. We can create our own event handler to apply custom logic to events such as an item getting created, saved, published, or deleted, and many others.
Consider a case where our application pulls a new press release from external resources. It creates and saves a news item in Sitecore, which should get published immediately without delay. Otherwise, consider a case where we have to export the details to an external data source immediately. In this recipe, you will learn how to intercept events to publish an item after it is saved.
