Application developed in Golang language.

Concept used for business development is DDD.

Pattern implementations to solve typical and repetitive problems.

Integrated SonarCloud in CI/CD pipeline is being used to review automated clean code checks.

Getting Started

Required
    - Golang

Features

Project Structure

Domain is the core of the application, it contains the business rules and the entities that represent the business.

aggregate root - root of the aggregate
entity - object with identity
factory - object that creates other objects
repository - object that manages the persistence of entities
service - object that implements business rules
value object - object that does not have identity

Application is the layer that connects the domain with the external world, it is responsible for receiving requests and returning responses.

api - is the layer that receives requests and returns responses
service - is the layer that implements the business rules

Infrastructure is the layer that connects the application with the external world, it is responsible for receiving requests and returning responses.

cache - is a cache that stores data in a structured format
database - is a database that stores data in a structured format
logger - is a log aggregator that collects logs from different sources and stores them in a central location
metrics - is a monitoring tool that collects metrics from different sources and stores them in a central location
tracing - is a tool that collects traces from different sources and stores them in a central location

DDD Domain Drive Design

This project uses a lot of the ideas introduced by Eric Evans in his book Domain Driven Design, which is a great book that I recommend to anyone who wants to learn more about the subject.

Strategic Design

Contributing

For major changes, open a problem first to discuss what you would like to change.

Codification

Attention, do not write, change or delete anything in the code from the main branch (default), for any new functionality you must create a new branch

To create a new branch run the command git checkout -b <branch-name>
- To switch from one branch to another existing in your local repository run git checkout <branch-name> without -b
Once you have finished coding on the new branch, push it to GitHub with the command git push -u origin <branch-name>
- After this step, open a pull-request for the main branch and wait for the Admin to analyze and merge the pull-request
