Summary
What is event sourcing
Event sourcing is a development pattern to solve audit problems and make our application more easily maintainable. It is described as:
A way to capture all changes to an application state as a sequence of events.
There's not much jabber about it right now, however this pattern first emerged in one of Martin Fowler's articles in 2005, for some reason it's been forgotten ever since.
I'm not describing it all here, however I have a series of related material (in portuguese) so you can study it for yourself.

Running the application
This app uses Docker Compose as runner, it'll build and set all your containers, you just need to run docker-compose up in the root directory.
