go-structure-examples VS fx

I have a question, I am trying out hexagonal architecture for one of my projects trying to follow this repository example and I ran into a slight problem.

Just fyi, that repo is NOT considered standard, and in fact, is often advised against. The structure of your code should depend on its complexity and how interoperable with other projects you need/would like it to be. I suggest watching this talk on structuring your code and taking a look at this companion repo to decide which will be the best way to structure your code, depending on your needs

Kat Zien's excellent talk, presentation and code samples can be found here.

Thanks for the video, I'll take a look at it. And I checked the repo, I liked how the new is structured: https://github.com/katzien/go-structure-examples/tree/master/new

So here’s where I normally tell people to start off: check out this video and this repo in regards to the main 6 ways of architecting your Go applications.

Watch this and give this repo a look.

Am I completely fumbling it by approaching this the wrong way & if so what should I do differently? I have searched a few repos like this which redefines the same entity in multiple places which I feel is a violation of some sort, and this which the author had to resort to moving some files outside to overcome a circular dependency (see comments inside their handling.go file).

Really surprised I haven’t seen katzien/go-structure-example and her GopherCon 2018 talk about structuring your Go projects mentioned yet

Let's agree to leave the MVC model for OO languages. A better architecture would be something like katzien/go-structure-examples

I found fx(https://github.com/uber-go/fx) to be a super simple yet versatile tool to design my application around.

All the advice in the article is still helpful, but it takes the "how do I make sure X is initialized when Y needs it" part completely out of the equation and reduces it from an N*M problem to an N problem, ie I only have to worry about how to initialize individual pieces, not about how to synchronize initialization between them.

I've used quite a few dependency injection libraries in various languages over the years (and implemented a couple myself) and the simplicity and versatility of fx makes it my favorite so far.

Some of the features: - ✅ Using Vertical Slice Architecture as a high level architecture - ✅ Using Event Driven Architecture on top of RabbitMQ Message Broker with a custom [Event Bus](pkg/messaging/bus/) - ✅ Using Event Sourcing in Audit Based services like [Orders Service](services/orders/) - ✅ Using CQRS Pattern and Mediator Patternon top of Go-MediatR library - ✅ Using Dependency Injection and Inversion of Controlon top of uber-go/fx library - ✅ Using RESTFul api with Echo framework and using swagger with swaggo/swag library - ✅ Using Postgres and EventStoreDB to write databases with fully supports transactions(ACID) - ✅ Using MongoDB and Elastic Search for read databases (NOSQL) - ✅ Using OpenTelemetry for collection Distributed Tracing with using Jaeger and Zipkin - ✅ Using OpenTelemetry for collection Metrics with using Prometheus and Grafana - ✅ Using Unit Test for testing small units with mocking dependent classes and using Mockery for mocking dependencies - ✅ Using End2End Test and Integration Test for testing features with all of their real dependeinces using docker containers (cleanup tests) and testcontainers-go library

any take on https://github.com/uber-go/fx?

I’m not sure of much that can do all of that - maybe it’s a use case for https://github.com/uber-go/fx

If I still find myself stuck/waiting, I switch over to studying more about our team's main language Go. Currently looking around at Fx ( https://github.com/uber-go/fx ). Which is interesting, though I doubt we'll actually migrate anything for it, but might make a neat lunch and learn topic.

Hello gophers, I am using https://github.com/uber-go/fx and https://github.com/rs/zerolog for logging.

Also, I like to use Uber FX for my DI stuff. You can check it out here:https://github.com/uber-go/fx

I only have private and work repos... But I use Uber fx. https://github.com/uber-go/fx

Spring Boot is notable for its dependency injection / inversion of control. The closest Go has to this is Uber's Fx which also includes some lifecycle management.

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.
