DDD Technical Architecture Patterns: Golang

A Simple Implementation of DDD Technical Architecture Patterns in Go.

Modular Version: https://github.com/d3ta-go

Diagram v 0.2.2

Components

A. Interface Layer (Composite Interface)

1. REST API - using Echo Framework

B. Modules:

1. Geolocation - using CRUD Architecture Pattern (GORM)
2. Authentication - using DDD Layered Architecture (GORM)
3. Email - using DDD Layered Architecture (GORM, SMTP)
4. Covid19 - using DDD Layered Architecture (Adapters -> Connectors)

C. Common System Libraries:

1. Configuration - using yaml
2. Identity & Securities - using JWT, Casbin (RBAC)
3. Email Sender - using SMTP

D. Others

1. Migrations - using GORM

E. Databases

1. MySQL (tested)
2. PostgreSQL (untested)
3. SQLServer (untested)
4. SQLite3 (untested)

F. Providers (Connectors)

1. data.covid19.go.id (Official Covid19 Website - Indonesia)
2. covid19.who.it (Official Covid19 Website - WHO)

G. Persistent Caches

1. Session/Token/JWT Cache (Redis, File, DB, etc) [tested: Redis]
2. Indexer/Search Cache (ElasticSearch)

H. Messaging [to-do]

I. Logs [to-do]

Development

1. Clone

$ git clone https://github.com/muharihar/d3ta-go.git

2. Setup

a. copy `conf/config-sample.yaml` to `conf/config.yaml`

b. setup your dependencies/requirements (e.g: database, redis, smtp, etc.)

3. Development

$ cd d3ta-go
$ go run main.go db migrate
$ go run main.go server restapi

4. Build

$ cd d3ta-go
$ go build
$ ./d3ta-go db migrate
$ ./d3ta-go server restapi

5. Distribution [to-do]

$ cd d3ta-go
$ sh dist.sh

Pic: REST Server is running!
