Since this is an Open source project and people should be able to clone and might use the app for their own personalized link, I think it's better to have the domain used in whole application more dynamic.
For example currently we are hosting on https://ristek.link
but if someone wants to serve it in his own domain https://link.myownweb.com we can make it easier and dynamic for self-customizing.

we can change all static domain like this with ${window.location.host} so it can be dynamically read the host domain where application served.
