accessibility

animation

applicationCache

audits

Audits domain allows investigation of page violations and possible improvements.

backgroundService

Defines events for background web platform features.

browser

The Browser domain defines methods and events for browser managing.

cacheStorage

cast

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

console

This domain is deprecated - use Runtime or Log instead.

css

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

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

deviceOrientation

dom

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.

domDebugger

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.

domSnapshot

This domain facilitates obtaining document snapshots with DOM, layout, and style information.

domStorage

Query and modify DOM storage.

emulation

performance

performanceTimeline

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

profiler

runtime

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.

schema

This domain is deprecated.

security

Security

serviceWorker

storage
