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

b. setup your dependencies/requirements (e.g: database, redis, smtp, etc.)
  1. Development
$ cd d3ta-go
$ go run main.go db migrate
$ go run main.go server restapi
  1. Build
$ cd d3ta-go
$ go build
$ ./d3ta-go db migrate
$ ./d3ta-go server restapi
  1. Distribution [to-do]
