Modules

• accessibility
• animation
• audits
  Audits domain allows investigation of page violations and possible improvements.
• autofill
  Defines commands and events for Autofill.
• background_service
  Defines events for background web platform features.
• bluetooth_emulation

• browser
  The Browser domain defines methods and events for browser managing.
• cache_storage
• cast
  A domain for interacting with Cast, Presentation API, and Remote Playback API functionalities.
• 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
• device_access
• device_orientation
• 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.
• dom_debugger
  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.
• dom_snapshot
  This domain facilitates obtaining document snapshots with DOM, layout, and style information.
• dom_storage
  Query and modify DOM storage.
• emulation
  This domain emulates different environments for the page.
