Represents different stages in a page’s lifecycle. Used to determine when a navigation or page load operation is considered complete.

Definition

enum LifecycleEvent {
  DOM_CONTENT_LOADED
  LOAD
  NETWORK_IDLE
  COMMIT
}

​
Values

​
DOM_CONTENT_LOADED

Wait until the `DOMContentLoaded` event is fired. This means the HTML has been fully loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading.

​
LOAD

Wait until the `load` event is fired. This typically means the page and all its dependent resources (stylesheets, images) have finished loading.

​
NETWORK_IDLE

Wait until there are no more than 0-2 network connections for at least 500 ms. This is often the most reliable way to ensure a page is fully loaded and ready for interaction.

​
COMMIT

Wait until a navigation commits. This is useful for tracking navigations that might not reach `DOMContentLoaded` or `load` states, for example, when navigating to a PDF or a file download.
