8. Mini Project
8. 2 . Backend
Spring Boot is a tool that facilitates the rapid and easy development of Java-based web applications. Built on top of the
Spring Framework, Spring Boot automates many configuration tasks required for starting and configuring projects, thereby
enhancing productivity. When discussing it comprehensively, it can be structured into key aspects: history and evolution, core
features, internal operational mechanisms, as well as use cases and ecosystem.
Here's a detailed list of the topics
