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_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.
