vardius/go-api-boilerplate

This system is a microservices-based authentication and user management platform, comprising separate services for handling OAuth2 client credentials, access tokens, and user registration via email and social providers. It features a React web application for user interaction and a Go backend that supports pluggable persistence backends (MySQL, MongoDB, or in-memory) with event-sourced repositories. The architecture exposes HTTP and gRPC interfaces for all services, supported by shared infrastructure for event buses, middleware, and Kubernetes deployment.

How it got here

2017–2019 · Service extraction and infrastructure modernization

The project underwent a major architectural shift, extracting the authentication and user services into independent, containerized components with dedicated gRPC and HTTP interfaces. This period focused on modernizing the build and CI/CD pipelines, replacing legacy in-memory and DynamoDB storage with robust MySQL and MongoDB persistence, and introducing structured error handling and event-sourced repositories for improved reliability and scalability.

48 changes

2020 · Full-stack architecture and persistence layer

This period focused on establishing a complete full-stack architecture, introducing a React-based web client alongside a robust Go backend. Significant work was done to implement configurable persistence backends (MySQL, MongoDB, SQLite) and comprehensive middleware for HTTP, gRPC, and authentication, while also adding event-driven messaging capabilities.

22 changes

2021 · Persistence and infrastructure modernization

This period focused on modernizing the system's data layer by introducing MongoDB persistence for authentication and user services, alongside in-memory alternatives for testing. Concurrently, the infrastructure was refactored to use Terraform and Helm, standardizing the deployment of microservices on Kubernetes.

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 3 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 1fb92f6f5a — 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.
