fx VS wild-workouts-go-ddd-exampl

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

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.

I've been looking into fx by Uber. Looks pretty cool, but I haven't had the chance to do anything more than a hello, world with it.

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.
