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.


        enabled: true
        orientation: "landscape"

With the above manifest configuration, the application will default to landscape orientation when launched from a device's home screen.
