Shared code starts with good intentions: stop copying the same tracing setup, validation rules, or test helpers into every service. Then, six months later, you have a mystery JAR that pulls in half of Spring, overrides application beans, and requires a Slack message to configure.

The problem is not sharing code. The problem is treating a shared library as a bucket of reusable classes instead of a product with consumers, compatibility promises, and a sensible onboarding path.

In this post we'll look at:

• A module layout that keeps framework code contained — core code stays portable while Spring Boot integration stays convenient
• Starters and auto-configuration that help instead of hijack — useful defaults with clear escape hatches
• Configuration and test support as part of the public API — discoverable properties and reusable conventions
• Documentation and releases that scale to more than one project — fewer archaeology sessions and safer upgrades

In this guide, we'll walk through setting up a robust testing environment for your React application using Vitest and React Testing Library. This combination provides a modern, fast, and efficient way to test your React components.
