In a simple Spring Boot application, dependencies play a significant role in occupying a large space in the application, with some dependencies containing hundreds of thousands of lines of code. Analyzing the dependency tree reveals that even a small number of dependencies can have a substantial impact on the overall size and complexity of the application. To mitigate this issue, it is essential to implement a robust Java dependency management strategy, including tools like Snyk for vulnerability scanning and detection, to ensure the maintainability, scalability, predictability, and safety of the application. By taking care of dependencies, developers can reduce the risk of security vulnerabilities and improve the overall quality of their codebase.
