You might have heard about it before: Most of the time it doesn't make any sense to write software from scratch. Instead, existing software should be refactored – especially when there's no one who understands anymore what exactly some piece of code actually does. Refactoring refers to changing the internal structures of code without diminishing its funtcionality. What is the best way to achieve this goal, especially in large applications?
RabbitMQ is an open source message broker, useful in almost any technology stack. It's built in Erlang and has a reputation for being a robust and reliable technology.

The two greatest foes of every software developer are a) uncertainty and b) complexity. Over the years, we have invented many tools and methods to fight them. But eventually, we realized that uncertainty cannot be defeated and instead we learned to embrace it with ever shorter feedback cycles, "agile" methods, continuous integration, devops and Test-Driven Development.
The term dependency injection refers to a technique whereby the dependencies of one object are supplied – or injected – by another object. Instead of letting the client (the object that needs those dependencies) build or find the dependencies, the dependencies would be passed to the object. That’s the whole meaning of dependency injection – actually, a pretty simple concept. But let's have a deeper look.
