A Go example

You'll need go 1.23 at least.

There's a Makefile, so you can do:

$ make clean
$ make test
$ make
$ make run

If you run:

go install golang.org/x/tools/cmd/goimports@latest
go install github.com/daixiang0/gci@latest
go install mvdan.cc/gofumpt@latest

then you can do make fmt to format all the source files.

If you go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest, you can also do make lint to get a linting / critique of all the source files (lint runs fmt first, so you need to have installed the packages above as well).

Note that the Makefile is for development, it's not used after the code is built.

Structure

the entry points go under cmd/, with a matching target in the Makefile
the factory constructs all the singletons that actually do things (e.g. listeners, models, clients, business logic objects)
the config handles all configuration for the entire application
