Socket Server

• Redis
• Typescript

Basics

Dependency installation

• node 14.17.2
• npm 6.14.13
• Then you can run npm install to finally install packages.

Running the whole service locally

To run a complete local service using docker compose, run:

1. npm run build
2. docker-compose up
3. npm run start:server1
