This is a project cloned from CoreUI, a free admin template based on the most populars js frameworks, see details below.
CoreUI is based on Bootstrap 4 and offers 6 versions: HTML5 AJAX, HTML5 Static, AngularJS, Angular 2+, React.js & Vue.js.
This version uses VueJS dist, and it was modified to work with my another project [OAuth2 With Spring Boot] (https://github.com/fabiogodoy/spring-boot-oauth2)
Here we have a form to create new users using OAuth2 architecture, and also a form for authentication.
Another important note is tha all routes are secure, except login, so if you try to access a protected resource you will be redirect to login page.
It is just a PoC but I think that could be useful.
