DevToolsClient Properties

Accessibility

Animation

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.

CacheStorage

Capture the current SynchronizationContext so continuation executes on the original calling thread. If Current is null for ExecuteDevToolsMethodAsync(String, IDictionaryString, Object) then the continuation will be run on the CEF UI Thread (by default this is not the same as the WPF/WinForms UI Thread).

A domain for interacting with Cast, Presentation API, and Remote Playback API functionalities.

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.

Database

Debugger domain exposes JavaScript debugging capabilities. It allows setting and removing breakpoints, stepping through execution, exploring stack traces, etc.

DeviceAccess

DeviceOrientation

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.<p>Note that `iframe` owner elements will return corresponding document elements as their child nodes.</p>

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.

EventBreakpoints permits setting breakpoints on particular operations and events in targets that run JavaScript but do not have a DOM. JavaScript execution will stop on these operations as if there was a regular breakpoint set.

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.

HeapProfiler

IndexedDB

Input

Inspector

Input/Output operations for streams produced by DevTools.

LayerTree

Provides access to log entries.

This domain allows detailed inspection of media elements

Memory

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.

Performance

Reporting of performance timeline events, as specified in https://w3c.github.io/performance-timeline/#dom-performanceobserver.

Preload

Profiler

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.

Security

ServiceWorker

Storage

When not null provided SynchronizationContext will be used to run the contination. Defaults to null Setting this property will change CaptureSyncContext to false.

The SystemInfo domain defines methods and events for querying low-level system information.

Supports additional targets discovery and allows to attach to them.

The Tethering domain defines methods and events for browser port binding.

Tracing

This domain allows inspection of Web Audio API. https://webaudio.github.io/web-audio-api/

This domain allows configuring virtual authenticators to test the WebAuthn API.
