MicroService Interface/Presentation App: Email GraphQL API

As a part of Simple Implementation of Modular DDD Technical Architecture Patterns in Go.

Diagram v 0.2.2-Modular

Components

A. Interface Layer (MicroService)

1. Microservice: Email GraphQL API [ d3ta-go/ms-email-graphql-api ]

B. DDD Modules:

1. Email - using DDD Layered Architecture (Contract, GORM, SMTP) [ d3ta-go/ddd-mod-email ]

C. Common System Libraries [ d3ta-go/system ]:

1. Configuration - using yaml
2. Identity & Securities - using JWT, Casbin (RBAC)
3. Initializer
4. Email Sender - using SMTP
5. Handler
6. Migrations
7. Utils

D. Databases

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

E. Persistent Caches

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

F. Messaging [to-do]

G. Logs [to-do]

Development

1. Clone

$ git clone https://github.com/d3ta-go/ms-email-graphql-api.git

2. Setup

a. copy `conf/config-sample.yaml` to `conf/config.yaml`
b. copy `conf/data/test-data-sample.yaml` to `conf/data/test-data.yaml`
c. setup your dependencies/requirements (e.g: database, redis, smtp, etc.)

3. Runing on Development Stage

$ cd ms-email-graphql-api
$ go run main.go db migrate
$ go run main.go server graphqlapi

4. Build

$ cd ms-email-graphql-api
$ go build
$ ./ms-email-graphql-api db migrate
$ ./ms-email-graphql-api server graphqlapi

5. Distribution (binary)

Binary distribution (OS/arch):

• darwin/amd64
• linux/amd64
• linux/386
• windows/amd64
• windows/386

$ cd ms-email-graphql-api
$ sh build.dist.sh
$ platform: [choose from OS/arch list, for example: darwin/amd64]
$ cd dist/[OS-arch]/
$ ./ms-email-graphql-api db migrate
$ ./ms-email-graphql-api server graphqlapi
