This webapplication was part of an exam project of mine. It might not be in a 'finished' state, as many more features may be added. As of right now, it works and you can use it (i.e. for learning for exams or practicing your memory skills).
npm ci
npm start
HOST=server_name
and fill in a temporary private key below -----BEGIN OPENSSH PRIVATE KEY-----
.
You can then run it by typing ./expose-http
in the console.
