Code Once, Use Everywhere: Building Shared Libraries for Multiple Projects

Vadzim Prudnikau - Apotek 1

Developers who have worked on shared libraries know that maintaining them can quickly become a headache, often leading to bugs or bottlenecks across projects.

• What should go into a shared library?
• How do you keep it small and easy to maintain?
• How do you update it without breaking everything?

These and other questions arose when I built a shared Java library that supports integration with Spring Boot across multiple projects in my company. In this talk, I’ll show how I addressed these challenges and developed a solution that has worked successfully for over three years. I’ll walk you through the structure and code so you can see exactly how it’s done and avoid common mistakes.

By the end, you’ll have actionable insights to start building or improving your own shared libraries that support Spring Boot.

Join my talk to discover practical solutions you can apply to your projects right away, whether you’re just starting or looking to enhance an existing shared codebase.

I look forward to seeing you at my talk!
