Events

Toy application displaying the power of docker-compose and modular web application design.

Service	Description
Web	Nginx proxy for Front and Api
Api	HTTP API that allows listing existing events
Front	React/Webpack/Node app for HTML interface
Worker	Listens on "events" Rabbit exchange and saves incomming events into a database

Setup

Create events database table:

docker-compose up db &
docker-compose exec db su -c 'createdb events' postgres

This is the most dubious part. Maybe it could be done programaticaly?

Start the app:

docker-compose up

Publish an event:

docker-compose exec worker publish '{ "event": "yohohoho!" }'

List API actions:

$ curl localhost:3000

{ "supported_actions": ["GET /events"] }

List events:

$ curl localhost:3000

[{"id": 1, "description": {"event":"hello"}]
