Golang Clean Architecture V2

I have started to journey with my backend developer career for 1 year and 8 months. I have learned a success or a mistake in my coding skills.

Thus, In this article, I’m going to walk you through the topic of how to implement clean architecture in Golang and connect PostgreSQL with GORM using Docker.

It’s not just the clean architecture but I’m trying to apply the SOLID principle also.
