wild-workouts-go-ddd-exampl VS wire

Take a look at: https://github.com/ThreeDotsLabs/wild-workouts-go-ddd-exampl...

(I’m one of the authors.)

This project shows how to apply more complex patterns popular in business applications while staying true to the Go ideas, and not copying them blindly from Java.

In the Go community, you’ll often hear people say „just keep things simple” beats all patterns and is all you need. This may be true if you write a CLI tool or a small library, but if you have a team maintaining a big application, some patterns are super helpful.

Hey HackerNews!

One o the most common problems in IT projects is the problem of out-of-date documentation or lack of documentation. Architecture diagrams are an essential part of it.

C4 Model is trying to help with that by providing a tool that helps to standardize a way to create clear architecture diagrams on multiple levels.

But having a standard practice to follow is not enough to have this documentation up-to-date. Because of that, Krzysztof from my team created a script that can make these diagrams directly from the code.

Unfortunetly we can't share our company code. Fortunately, we have Wild Workouts DDD example that is a perfect use case to show the power of that tool: https://github.com/ThreeDotsLabs/wild-workouts-go-ddd-exampl....

The linked article describes all the needed steps to create these diagrams. Feel free to play with it and try to add it to your project.

If you want to know more about Wild Workouts DDD example, they are already 14 articles that describe the project in detail: https://threedots.tech/series/modern-business-software-in-go....

Here is example code and blog series for a step-by-step DDD-based refactoring of an existing app. Don't know if they are the same as what's used in the book, but found them quite interesting.

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.
