Go is amazing for backend development 
But to build production grade applications, there is a lot of efforts and boilerplate to put in place if you’d like to build a backend using Golang, or even to explore this ecosystem, you can check Yokai on GitHub.
=> GitHub - ankorstore/yokai: Simple, modular, and observable Go framework for backend applications..
It has a strong focus on observability (built in logs, traces and metrics instrumentations), on testing and extensibility.
There is ready to use app templates and tutorials you can find in the documentation (link in readme) to kick start your HTTP, gRPC or even worker applications. And you can also find there ready to run demo applications to see it in action.
Feel free to ask any questions, and I hope this will help you in your backend journey
