Tic-Tac-Toe game with load balancer, state manager and websockets

Overview

This project is written without using any frontend and backend libraries such as React.js or Express or whatever. This is done intentionally to show that is not that hard to write a backend on pure Node. Same goes with frontend, but, frankly speaking, I would rather use something like React. Webpack config was probably the hardest task for me. Additionally I haven't used classes syntax, just for fun.

Technologies and tools

• JavaScript - main programming language
• Node.js - runtime for application
• PostgreSQL - main database for storing user data
• Redis - as a database for storing game session data
• Nginx - load balancer
• Docker - containerization tool
• Docker Compose - used to run two instances of main app and separate database all with one command
• Webpack - to bundle client code
• HTML/CSS - for styling and layout of webpages

Steps to run project

1. Clone repository
2. Cd into project directory
