To enable wake lock:

NOTE: This function call must be wrapped in a user input event handler e.g. a mouse or touch handler

// Enable wake lock.
// (must be wrapped in a user input event handler e.g. a mouse or touch handler)
document.addEventListener(
  'click',
  function enableNoSleep() {
    document.removeEventListener('click', enableNoSleep, false);
    noSleep.enable();
  },
  false,
);

To disable wake lock:

// Disable wake lock at some point in the future.
// (does not need to be wrapped in any user input event handler)
noSleep.disable();
