7 Open‑Source Projects to Master Front‑End/Back‑End Separation in Java

Front‑end/back‑end separation is increasingly adopted by companies; even if your organization hasn't switched, learning this architecture is essential to stay competitive.

The concept is simple: the back‑end provides APIs while the front‑end displays data. Developers accustomed to monolithic development often carry old habits into a separated architecture, resulting in suboptimal products. Below are several open‑source projects that help you quickly master the stack.
