NATSY

An example project for learning how to use nats-server and async event patterns from Go services.

Overview

Project contains two small Go services: Api-Producer & Consumer. This repo is for learning purposes and to help us establish working norms when using this technology.

Api-Producer

Exposes API endpoints that cause async events to be created

• POST /products

  • Creates event on subject
  • price.created

• GET /ping

  • Creates event on subjects
  • ping.db.status
  • ping.api.status
  • ping.redis.status

• API Request and Event models are clearly separated.

• Higher level EventEnvelope captures lower level subject specific data

Consumer

Simulates long running consumer for messages. Trying to show power and importance of subject naming through ping example Subscribed to subjects:

• ping.*.status
• price.created

Processes top level EventEnvelope before switching on subject to parse underlying data.

Simulates a DB connection with a map

• TODO add API to access keys
