ddd-by-examples/library

This system is a library management service that handles the full lifecycle of book lending, including checkouts, holds, and overdue tracking. It provides a RESTful API for managing patron profiles, placing or canceling holds, and viewing current checkouts. The architecture enforces clean boundaries between domain models, application logic, and infrastructure, supported by comprehensive integration and unit tests.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 31 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 98d7004b5a — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
