fx VS golang-standards/project-layout

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.

cmd: here where we will leave the main.go that starts our app.

The name of the repo is really and intentionally misleading. rsc filled an issue there to point this out, but the repo maintainer just disabled issues altogether so now no one can see it.

Even when it would not have such parasitic name, many seasoned Go programmers, me included, consider the self-proclaimed "Standard Go project Layout" as the opposite of what is good and advisable.

Unfortunately, the name just works, so it is being recommended all over the Internet since its inception.

Your comment makes it look as if you're saying you hate the Go development team, but it seems that isn't the case.

I get a little of what you're saying, I wouldn't say I hate anyone, but I strongly dislike how a lot of projects are organized. I think a lot stems from https://github.com/golang-standards/project-layout , which pretended to be standard and was so (ab)used one of the creators opened an issue about it. If you look at the actual Go src, it's much, much cleaner.

So you don't get blind sided for self proclaimed "standards" that are not

I am writing a project that has two components: a CLI and a library. I've organised the project as follows (as per organisation instructions):

Familiarity with the standard Golang project structure, which you can find here.

I've been learning how to build web applications using different frameworks and languages for a while now, such as Laravel with its MVC architecture and Node.js following the 'Hapi.js Way'. As I'm trying to create a new portfolio project using Go, I found myself contemplating over the ideal project structure. I wanted something that not only aligns with the standard Go project layout, but also makes the code both easy to write and understand. That's when I stumbled upon the concept of Hexagonal Architecture, as showcased in Netflix's engineering blog. The idea of seamlessly swapping infrastructures with minimal code changes fascinated me, and I decided to implement it in my new project.
