I think it is this:

export function eulerToQuaternion(roll: number, pitch: number, yaw: number): Quaternion {
  const sr = Math.sin(roll * 0.5);
  const cr = Math.cos(roll * 0.5);
  const sp = Math.sin(pitch * 0.5);
  const cp = Math.cos(pitch * 0.5);
  const sy = Math.sin(yaw * 0.5);
  const cy = Math.cos(yaw * 0.5);

  const w = cr * cp * cy - sr * sp * sy;
  const x = cr * sp * cy + sr * cp * cy;
  const y = cr * sp * cy - sr * cp * sy;
  const z = cr * cp * sy + sr * sp * cy;

  return { x, y, z, w };
}
