Requirements

Software	Version
Go	1.21.X

Install Go

Windows

choco install golang

Debian based

apt install golang-go

Mac OS X

brew install go

Other installation methods: Download Golang

Start

1. Clone this project

2. Configure your environment variables ".env" file, you can use the ".env.example" file as a guide

3. Execute the following command to download the dependencies

   go mod tidy

4. For run the project execute the following command

   go run cmd/<service-name>/main.go

5. Happy hacking :D

Start with docker

1. Install docker v24.0.2 how to install?

2. Install docker compose v2.18.1 how to install?

3. Clone this project

4. Copy environment configuration

   cp .env.example .env

5. Execute the project with the following command

   docker-compose up -d

6. Run mongodb seeders. Note: this command will execute the seeders in a default mongo db called app

   make mongodb-seeders

   if you want to customize the mongo db name (if you change MONGO_DATABASE in .env file), you can use the following command

   make mongodb-seeders MONGO_DATABASE=<your-db-name>

7. For next steps see Trying the service (only for docker)

Trying the service (only for docker)

with makefile

make testing-service

expected output

============================================================
Creating new order...

{"id":"6560ec6df49b452dade3e61e","first_name":"John","last_name":"Doe","sub_example":{"sub_example_id":123,"sub_example_name":"subExampleName"}}
============================================================
Searching order from seeder

{"id":"656045095ff16ef1a00fd4ef","first_name":"John","last_name":"Doe","sub_example":{"sub_example_id":123,"sub_example_name":"subExampleName"}}
============================================================

Or step by step

Create Example Order

curl --location --request POST '127.0.0.1:8080/api/v1/order/create'

Retrieve Example Order

curl --location '127.0.0.1:8080/api/v1/order/656045095ff16ef1a00fd4ef'

Built with

Domain

The domain layer encapsulates the application's business logic, integrating data entities and ports that abstract this logic.

Implementation

The implementation layer is responsible for executing the specific technical details and interactions of an application. It implements everything defined in the ports and utilizes the entities. Dependency injection is used in this layer to facilitate the use of other services and repositories, thereby realizing the concepts defined in the domain layer through concrete implementations and interfacing with external systems and managing data flow.

Infrastructure

The architecture layer in software design provides the structural blueprint for the application. It outlines how various components such as the domain, implementation, and presentation layers interact and are organized. This layer focuses on aspects like scalability, maintainability, and technology stack, ensuring that the application's overall structure supports its requirements and goals.
