The orientation property in the Progressive Web Application (PWA) manifest dictates the default orientation that the web application will be displayed in. The allowed values are:
portrait-primary: The orientation is in the primary portrait mode.
landscape-primary: The orientation is in the primary landscape mode.
portrait: Either of the portrait orientations.
landscape: Either of the landscape orientations.
any: Any orientation.
Setting the orientation helps ensure that the PWA looks good and functions well on mobile devices.
Example:
/config/packages/pwa.yaml
pwa:manifest:enabled:trueorientation:"landscape"
With the above manifest configuration, the application will default to landscape orientation when launched from a device's home screen.
