Choose the UI That Matches Your Endpoints

Your UI path follows the backend architecture selected in Java Spring Hacks.

GitHub Pages with /api/*

A separate JavaScript frontend calls the REST API and renders its JSON response. Keep the backend URL in config.js.

const response = await fetch(`${javaURI}/api/data`);
const data = await response.json();

The /api/* endpoints use SecurityConfig.java with Order(1). CORS must allow the GitHub Pages origin.

Thymeleaf with /mvc/*

Thymeleaf templates are served by Spring and submit same-origin HTML forms to /mvc/*. The MVC filter chain is MvcSecurityConfig.java with Order(2) and uses session and CSRF protection.

Do not combine the endpoint patterns for this assignment: fetch JSON from /api/*, or render templates and submit forms through /mvc/*.
