Module cdp::emulation

This domain emulates different environments for the page.

Emulation

Commands

• Emulation.setDeviceMetricsOverride

  Overrides the values of device screen dimensions (window.screen.width, window.screen.height, window.innerWidth, window.innerHeight, and "device-width"/"device-height"-related CSS media query results).

• Emulation.clearDeviceMetricsOverride

  Clears the overriden device metrics.

• Emulation.resetPageScaleFactor Experimental

  Requests that page scale factor is reset to initial values.

• Emulation.setPageScaleFactor Experimental

  Sets a specified page scale factor.

• Emulation.setVisibleSize Experimental [Deprecated]

  Resizes the frame/viewport of the page. Note that this does not affect the frame's container (e.g. browser window). Can be used to produce screenshots of the specified size. Not supported on Android.

• Emulation.setScriptExecutionDisabled Experimental

  Switches script execution in the page.

• Emulation.setGeolocationOverride Experimental

  Overrides the Geolocation Position or Error. Omitting any of the parameters emulates position unavailable.

• Emulation.clearGeolocationOverride Experimental

  Clears the overriden Geolocation Position and Error.

• Emulation.setTouchEmulationEnabled

  Enables touch on platforms which do not support them.

• Emulation.setEmitTouchEventsForMouse Experimental

• Emulation.setEmulatedMedia

  Emulates the given media for CSS media queries.

• Emulation.setCPUThrottlingRate Experimental

  Enables CPU throttling to emulate slow CPUs.

• Emulation.canEmulate Experimental

  Tells whether emulation is supported.

• Emulation.setVirtualTimePolicy Experimental

  Turns on virtual time for all frames (replacing real-time with a synthetic time source) and sets the current virtual time policy. Note this supersedes any previous time budget.

• Emulation.setDefaultBackgroundColorOverride Experimental

  Sets or clears an override of the default background color of the frame. This override is used if the content does not specify one.

Events

• Emulation.virtualTimeBudgetExpired Experimental

  Notification sent after the virtual time budget for the current VirtualTimePolicy has run out.

• Emulation.virtualTimePaused Experimental

  Notification sent after the virtual time has paused.

Types

• ScreenOrientation

  Screen orientation.

• VirtualTimePolicy Experimental

  advance: If the scheduler runs out of immediate work, the virtual time base may fast forward to allow the next delayed task (if any) to run; pause: The virtual time base may not advance; pauseIfNetworkFetchesPending: The virtual time base may not advance if there are any pending resource fetches.
