EUS-web is the current frontend of EUS, my public screenshot server.
EUS-web requires an installation of EUS to work, see the EUS Setup guide for more details. Once EUS is installed drop EUS-web's files into the EUS/files folder and it should show on the server.
EUS-web makes use of the EUS API and therefore can not be used without EUS. The endpoints EUS-web makes use of are /api/get-stats and api/get-info
Along with making a new html file you will also need to add an entry to the buttons array in navbarHelper.js. When navbarHelper is initialised on a page you can define what page it is, this is used for highlighting which page you are on in the navbar.
For example the home page's initialiser looks like this
<script>
// Page initialiser
navbar("Home");
fetchStatsFromAPI();
</script>
