Go Backend Clean Architecture is a project template for building backend services in Go that demonstrates clean architecture principles with Gin, MongoDB, JWT authentication, testing, and Docker.
The project addresses the challenge of structuring Go backend applications following clean architecture patterns. It organizes code into distinct layers—Router, Controller, Usecase, Repository, and Domain—that separate concerns and make applications easier to maintain and test. This layered approach ensures that business logic remains independent of frameworks and external dependencies, allowing developers to swap implementations without affecting core functionality.
Developers should adopt this template if they are building REST APIs in Go and want a reference implementation of clean architecture practices. It works well for projects that require JWT-based authentication, MongoDB integration, and containerized deployment. The template includes working examples of testing patterns and configuration management, making it suitable for teams that prioritize code quality and maintainability from the start.
The project demonstrates consistent engagement with its audience through accompanying blog posts that explain architectural decisions, JWT implementation, configuration management with Viper, testing approaches using Testify and Mockery, and database design considerations. The maintainer actively maintains the repository as an educational resource and reference implementation, with documentation that supports developers learning clean architecture principles in Go.
