This is a simple chat messenger using Node.js and Typescript as the server backend. The web sockets were handled with the socket.io library. PostgreSQL was used to save messages and keep up with chat room data like the amount of people in a room, who is specifically in the room, etc. This was a simple personal project that I wanted to do.
Docker was used in this project as a learning experience. I wanted to learn containerization by using Docker and Docker Compose.
Before running the container, check that the variables in the .env file are the same in the docker-compose.yml
DB_USERNAME="postgres"
DB_PASSWORD="postgres"
DB_DATABASE="messenger"
DB_URL="db"
DB_PORT=5432
PORT=8080
After verifying the .env and docker-compose.yml files, run the command:
docker-compose up -d
and wait a few seconds for the containers to download and run.
From there, just connect to the website which should be located on localhost:${your_env_port}.

- Javascript/HTML/CSS
- Socket.io library
- PostgreSQL
- Docker
- Docker Compose
- Yarn
There are two tables used for the PostgreSQL database. The schema looks something like this:
- Altering the sessionStorage can possibly cause issues since that's how the username is being saved
- Encrypt text for privacy reasons
