do VS wire

How does this compare with https://github.com/samber/do ?

Last week I posted here about a new library that I released called hooks that was generally well-received. I've since built out an example application using hooks and do (excellent library for dependency-injection) to not only highlight use-cases for hooks but also to demonstrate the larger idea/concept I had for using hooks to build modular monoliths with Go that I wanted to share and perhaps start a discussion about.

It's not, but I've been thinking about it. I may experiment with it in a different branch of a different repo. I'm not sure if everyone would want hooks included or baked in to Pagoda, but I do think it would be a very good fit. I recently worked on and published an application example using hooks and do (for DI) to emphasize a fully modular architecture: https://github.com/mikestefanello/hooks-example. That highlights the vision I had for the overall approach with hooks, and I think it came out quite nice. I'd really like feedback on that, so if you have any, please let me know.

We use https://github.com/google/wire for every bigger project, take a look at it, it beautifully solves initialisation and also gives you a guideline on how to do it.

Im by no means a "purist" in such things, I love my magic and QoL-features/libs, but havent seen something that is so easy to use in go, that I immediately wanted to add it. And to be fair, I only looked closely at https://github.com/google/wire , others I have just skipped - and I will be looking into uber-fx as mentioned in the other comment.

If you have such a complex and deep dependency graph, and you don't want to manually maintain it, you could use some DI library to handle that for you. Something like https://github.com/google/wire for small-medium size stuff, or https://github.com/uber-go/fx for larger scale, more enterprise projects.

Try https://github.com/google/wire. Compile time generated like dagger 2 in java.

Most people probably do it by hand (I do). But otherwise, probably https://github.com/google/wire is the most popular, maybe followed by https://github.com/uber-go/fx.

For larger object graphs do you roll everything by hand or encourage something like https://github.com/google/wire

The other thing is that I'm lazy, so I don't construct all dependencies in main.go manually but use wire to generate the construction of my dependency tree.

This guy fucks. Modular monoliths is the way. The service initialization/wiring part could be simplified (given a bigger project ofc) using something like https://github.com/google/wire. But everything else... *chef kiss* beautiful.
