Diagrams. Loads and loads of diagrams. One for each use-case.
Then I’d have one diagram to draw out dependencies between each service at the broadest level. Although depending on how messy your architecture is it can be very difficult to read, in my experience.
As a bit of low-hanging fruit, you may be able to reduce the length of the diffs in an MR by marking generated files with -diff in a .gitattributes file. This is at least supported by GitLab (not sure about others): https://git-scm.com/docs/gitattributes#_marking_files_as_binary
To be honest, it doesn’t seem that bad. With clean architecture, you are going to end up with extra types and mappers. I would argue that what you have isn’t coupled, because a change in one place doesn’t have unexpected side effects elsewhere.
I haven’t used Goa or Gorm. Writing SQL by hand gets old quick so I get why you’d use Gorm - just less code to write in the end. I’ve used sqlc as it’s more a library than a framework, and it’s fine, but it can’t fulfill every use case. Goa looks too opinionated for me, on the face of it.
I’ve used wire. It takes some understanding but it’s definitely a lot to understand just to add a dependency. At work we’ve got our own template for doing dependency injection and although I was skeptical at first it strikes a really good balance between being understandable and abstracting away DI. If this is your pain point, I’d consider going back to basics and get rid of the framework.
If you decide to go with a framework like Laravel, Rails or Next.js and build everything around the framework, you will deliver quickly at first, but you won’t have type safety and it particular point it will stop scaling because these frameworks have no consideration for clean architecture. You won’t necessarily be better off.
If you wanted to do both front and backend development TypeScript + JS/Node would make the most sense, no? I say this as someone who works with and enjoys working with Go almost every day, but there’s only so much time to learn new stuff.
More or less. Either Excalidraw for your quick and dirty diagrams or I’ve used PlantUML + C4 Plug-in for your larger, more long lived diagrams with some success.
