Shouldn't it be:

const globalStorage = root.customStorage || {setItem: () => {},
  getItem: () => {},
  removeItem: () => {},
  clear: () => {}
};

this will allow overriding the global object and defining your own. Thoughts?

What would customStorage be?

Are you assuming this would be on the global object when used in a node environment? If so maybe it could be set as a property for use in server node apps. I'm not sure this library would be used on the server.

This would help in defining custom methods(get, set, etc.) when localStorage is not present(in case of incognito mode and cookies disabled scenario). It will help there.

localStorage is available in incognito. I'm not quite sure what scenario you are suggesting can you specify a browser etc.

@softvar any final thoughts?

setItem: () => {},
getItem: () => {},
removeItem: () => {},
clear: () => {}

Can we please also set the storage type on window?

this.ls = root[root.storageType || 'localStorage'] || globalStorage;

root in this context is the window, the aim was to stop the library breaking when used in ssr enabled applications.

I'm not aware of storageType as a window property

I think I may not provided enough context to the PR, sorry. I've had an issue with SSR in react this is my current work around when using SecureLS:

const getSecureLS = () => {
  if (typeof window !== 'undefined') {
    return new SecureLS({});
  }
  return {
    set: () => ({}),
    get: () => ({}),
    remove: () => ({}),
  };
};

this.init();
};
