2020–2023 · expansion of sample applications

This period focused on significantly expanding the repository's collection of reference implementations, introducing diverse examples for GraphQL, microservices, CQRS, Sequelize, Prisma, HTTP, file uploads, and MongoDB transactions. Each new sample application was accompanied by comprehensive unit and end-to-end tests to ensure reliability. Additionally, tooling was enhanced with automated migration scripts for the Nx monorepo structure and Husky hooks for code quality enforcement.

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 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 47ab935278 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
