Implementation of Asynchronous and Queue Subscriptions on NATS using Golang with Uncle Bob Clean Arch

Go Nats

Overview

NATS is an open source, lightweight, high-performance cloud native infrastructure messaging system. It implements a highly scalable and elegant publish-subscribe (pub/sub) distribution model. The performant nature of NATS make it an ideal base for building modern, reliable, scalable cloud native distributed systems.

Implemented with clean architecture by Uncle Bob in folder structure. Hopefully make you easier to implement this message broker.

So basically, this app was build using:

• Golang
• Nats

Prerequisite

• Install go v1.11 or above to use go modules
• Make vendored copy of depedencies

      go mod vendor

• Copy app.config.sample yml into decided environment. For example:

        bash run.sh
