Software Architecture in Golang: Maintainability using Linting, Code Coverage and CI

Welcome to another Software Architecture in Go video, in today's episode we are discussing Maintainability.

We are defining Maintainability as a way to measure success in our project, we refer to the book "Building Evolutionary Architectures" to determine what makes sense after using Github Action, golanci-lint and codecov.

In this episode I cover Maintainability using Continuous Integration in Go, to indicate a way to measure our changes; using Continuous Integration and adding automatic checks, like unit tests, linters and code coverage allows us as maintainers of our projects to keep track of possible deviations when making changes.

It's important to define a few rules around our projects, specifically conventions regarding the code, a great tool for doing that is "golangci-lint", please refer to the ones I choose for this project for some examples.

Tools used:

* Github Actions: https://github.com/features/actions
* golangci-lint: https://github.com/golangci/golangci-lint
* CodeCov: https://app.codecov.io/gh/MarioCarrion/todo-api-microservice-example
* Dependabot: https://docs.github.com/en/code-security/supply-chain-security/keeping-your-dependencies-updated-automatically/about-dependabot-version-updates
