Free Games Notifier for Discord

A Discord bot that will notify your server when free games on storefronts like Steam or Epic Games come out.

This bot depends on free-games-crawler and site support depends on that service.

For more information, please visit the official documentation site.

Usage

In order to use this project you'll need the following:

• Redis
• Doker (Recommended) or Node.js (At least version 20)

With Docker (Recommended)

Create a docker-compose.yml file with the following:

services:
  bot:
    image: ghcr.io/moonstar-x/discord-free-games-notifier:latest
    restart: unless-stopped
    depends_on:
      - redis
      - postgres
    environment:
      DISCORD_TOKEN: YOUR_DISCORD_TOKEN_HERE
      DISCORD_SHARING_ENABLED: false
      DISCORD_SHADING_COUNT: auto
      DISCORD_PRESENCE_INTERVAL: 30000
      REDIS_URI: redis://redis:6379
      POSTGRES_HOST: postgres
      POSTGRES_PORT: 5432
      POSTGRES_DATABASE: free-games
      POSTGRES_USER: discord
      POSTGRES_PASSWORD: SOMETHING_SECRET
  
  crawler:
    image: ghcr.io/moonstar-x/free-games-crawler:latest
    restart: unless-stopped
    depends_on:
      - redis
    environment:
      REDIS_URI: redis://redis:6379

  redis:
    image: redis:7.4-rc2-alpine
    restart: unless-stopped
    command: redis-server --save 60 1 --loglevel warning
    volumes:
      - ./redis:/data

  postgres:
    image: postgres:15-alpine
    restart: unless-stopped
    volumes:
      - ./postgres:/var/lib/postgresql/data
    environment:
      POSTGRES_DB: free-games
      POSTGRES_USER: discord
      POSTGRES_PASSWORD: SOMETHING_SECRET

Make sure to replace SOMETHING_SECRET with a password for your database and YOUR_DISCORD_TOKEN_HERE with your bot's token.

And start it up:

docker compose up -d

Once you have it, you should deploy the commands. To do this, run:

docker compose run bot npm run deploy:prod

With Node.js

Make sure to have at least Node.js 20.
