Patternfly-Chat

Patternfly-Chat is a real time chat application that allows realtime communication for groups and individuals.

It features an architecture comprised of a frontend, a cache micro service, a redis cache, and an instance of a keycloak server.

The authentication side is leveraged by Keycloak and which makes management of client applications, users, and assignment of permissions and roles extremely simple. Management of application concurrency is handled by the cache micro service which relies on composite key and streaming features of redis.

The frontend communicates directly to keycloak server and the cache.

The frontend is React and the Cache is Node with es6 mods.

Build Cache Service

docker build -t cacheservice:chatapp . docker build -t frontend:chatapp .

Backend API
