// Due north is rotated 180 degrees, pointing to the bottom of the view
view.rotation = 180;

// Due north is rotated 270 degrees, pointing to the left side of the view
view.rotation = 270;

// Due north is rotated 0 degrees, pointing to the top of the view (the default)
view.rotation = 0; // 360 or multiple of 360 (e.g. 720) works here as well.

// Disables map rotation
view.constraints = {
  rotationEnabled: false
};
