Transitioning from Spring to Spruce

Spring is a framework for creating complex, enterprise-level applications in Java. It provides a wide range of functionalities, from dependency injection to security, and much more. Spruce, on the other hand, is a TypeScript-based framework designed for building scalable web applications. This guide will help Spring developers understand how to transition to Spruce.
