Introduction

MessagingApp is a real-time messaging service built with Node.js, Mongodb, Express.js, Socket.IO, TypeScript and unit tested with Mocha and Chai.

Key features:

• Persistance messages in MongoDB
• Real-time message sending using WebSockets (Socket.IO)
• Scalable architecture with future ability to scale horizontally

Installation

 yarn

Docker

This project has ready to test docker-compose configs. There are two docker-compose and Dockerfiles, one for production and the other for development with hot reload and debug ability.

First, you'll need to copy .env.template and rename it to .env

It should look something like the following, for a Docker environment:

APP_PORT=8000                        # Exposed port for node.js server app
APP_HOST=localhost                   # localhost is ok on docker


# Config for MongoDB
MONGO_DB_NAME = "messagingDb"
MONGO_USER = "messagingDbUser"
MONGO_PASSWORD = "some-secret-pass"
MONGO_HOST = "mongodbserver"         # If you changed MONGO_HOST, remember to change it on docker-compose.yml also.
MONGO_PORT=27017

After setting .env, you are ready to run the backend services:

docker-compose up -d                                      # For production
# or
docker-compose -f ./docker-compose.dev.yml up -d          # For develpment and debugging
