This is an example Vue.js application developed with Spring Boot

+

This file is rendered by a Spring built-in default controller for index.html (/) using + Spring's built-in + Thymeleaf templating engine. + Although we don't need it per se, we customized the information passed to this + view from thymeleaf by adding a controller method for "/" route to demonstrate how to pass information from + Thymeleaf to this page. + The combination of template engine and frontend framework like Vue can make this a powerful approach to build + more complex applications while leveraging the benefits of a framework like Vue.js. + You can use thymeleaf features too but this project focuses mainly on using Vue.js on the + frontend as the framework and makes minimal use of Thymeleaf. + Also we don't use any routing and multiple components in this example, so what you see is technically a + Single Page Application (SPA) without any routes configured. +
