Page
A session created when attaching to a target of type Page.
The subset of domains available for this target type is not strictly defined by the protocol. The subset provided in this interface is guaranteed to work on this target type. However, some domains might be missing in this interface while being effectively supported by the target. If this is the case, you can use the unsafe function to access all domains.
As a subinterface of PageTarget, it inherits the generated domain properties that match the latest Chrome DevToolsProtocol definitions. As such, it is not stable for inheritance, as new properties can be added without major version bump when the protocol changes. It is however safe to use all non-experimental and non-deprecated domains defined here. The experimental and deprecation cycles of the protocol are reflected in this interface with the same guarantees.
Properties
(undocumented in the protocol definition)
(undocumented in the protocol definition)
Audits domain allows investigation of page violations and possible improvements.
Defines events for background web platform features.
The Browser domain defines methods and events for browser managing.
(undocumented in the protocol definition)
This domain exposes CSS read/write operations. All CSS objects (stylesheets, rules, and styles) have an associated id used in subsequent operations on the related object. Each object type has a specific id structure, and those are not interchangeable between objects of different kinds. CSS objects can be loaded using the get*ForNode() calls (which accept a DOM node id). A client can also keep track of stylesheets via the styleSheetAdded/styleSheetRemoved events and subsequently load the required stylesheet contents using the getStyleSheet[Text]() methods.
(undocumented in the protocol definition)
Debugger domain exposes JavaScript debugging capabilities. It allows setting and removing breakpoints, stepping through execution, exploring stack traces, etc.
(undocumented in the protocol definition)
(undocumented in the protocol definition)
This domain exposes DOM read/write operations. Each DOM Node is represented with its mirror object that has an id. This id can be used to get additional information on the Node, resolve it into the JavaScript object wrapper, etc. It is important that client receives DOM events only for the nodes that are known to the client. Backend keeps track of the nodes that were sent to the client and never sends the same node twice. It is client's responsibility to collect information about the nodes that were sent to the client. Note that iframe owner elements will return corresponding document elements as their child nodes.
DOM debugging allows setting breakpoints on particular DOM operations and events. JavaScript execution will stop on these operations as if there was a regular breakpoint set.
This domain facilitates obtaining document snapshots with DOM, layout, and style information.
Query and modify DOM storage.
This domain emulates different environments for the page.
This domain allows interacting with the FedCM dialog.
A domain for letting clients substitute browser's network layer with client code.
This domain provides experimental commands only supported in headless mode.

Info about this session and its underlying target.
Network domain allows tracking network activities of the page. It exposes information about http, file, data and other requests and responses, their headers, bodies, timing, etc.
This domain provides various functionality related to drawing atop the inspected page.
Actions and events related to the inspected page belong to the page domain.
The parent browser session that created this target session.

(undocumented in the protocol definition)
Runtime domain exposes JavaScript runtime by means of remote evaluation and mirror objects. Evaluation results are returned as mirror object that expose object type, string representation and unique identifier that can be used for further object reference. Original objects are maintained in memory unless they are either explicitly released or are released along with the other objects in their object group.
This domain is deprecated.
Security
(undocumented in the protocol definition)
(undocumented in the protocol definition)
The SystemInfo domain defines methods and events for querying low-level system information.
Supports additional targets discovery and allows to attach to them.
(undocumented in the protocol definition)
This domain allows configuring virtual authenticators to test the WebAuthn API.
Functions
Adapts this ChildSession to a AuctionWorkletSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a PageSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a ServiceWorkerSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a SharedStorageWorkletSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a SharedWorkerSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a WebContentsSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a WorkerSession. If the attached target is not of a compatible type, this function throws an exception.
Adapts this ChildSession to a WorkletSession. If the attached target is not of a compatible type, this function throws an exception.
Finds page targets that were opened by this page.
Finds a DOM element via the given selector, and simulates a click event on it based on its padding box. The current tab doesn't need to be focused.
Closes the underlying web socket connection, effectively closing every session based on the same web socket connection.
Navigates the current page to the provided url, and suspends until the configured completion events are fired. By default, this function suspends until the GotoCompletionEvent.Load event is fired.
Gives access to all domains of the protocol, regardless of the type of this session.
