We like to see:

• dependencies injection
• unit testing (with dependency mocking)
• defensive programming

Optional:

• simplicity
• more Makefile rules that make sense
• run inside container

• golang 1.17+
• echo (https://github.com/labstack/echo)
• swagger (github.com/deepmap/oapi-codegen, we write docs, we generate handlers...)
• docker
• testing (github.com/stretchr/testify)
• mockery (github.com/vektra/mockery)
