    Sakura Boot

    Sakura Boot

    Framework on top of spring-boot that helps create back-ends

    This framework, built on top of Spring Boot, is designed to speed up the development of robust backends. It ensures adherence to best practices while allowing a high degree of customization. The framework is structured using a modular architecture, making it easy to add or remove features based on the project’s specific needs. While Spring Boot speeds up the development process, developers still require extensive knowledge, must ensure adherence to best practices, and often write repetitive code for each project. First, the name Sakura Boot is named to reflect its foundation on Spring Boot, while "Sakura" symbolizing the brief cherry blossoms season in Japan, this highlights the framework’s focus on rapid and efficient backend development.
