Quickstart

Prerequisites

• Python 3.11 or higher
• pip (Python package manager)

Step 1: Create Project Directory

mkdir my-game
cd my-game

Step 2: Create Virtual Environment

# Windows
python -m venv .venv
.\.venv\Scripts\Activate

# macOS/Linux
python3 -m venv .venv
source .venv/bin/activate

Step 3: Install Daemons Engine

pip install daemons-engine

Step 4: Initialize Your Game

daemons init <new_game>

This creates:

• world_data/ YAML content (rooms, NPCs, items)
• config.py Server configuration
• main.py Application entry point
• alembic.ini Database migration config
• alembic/ Migration scripts

Step 5: Set Up Database

cd <new_game>
daemons db upgrade

Step 6: Run the Server

From /<new_game>...

# Development (auto-reload on code changes)
daemons run --reload

# Production (requires JWT secret key)
daemons run --production

The --production flag enables security hardening:

• Requires JWT_SECRET_KEY environment variable
• Enforces JWT issuer/audience validation
• Runs without auto-reload

If JWT_SECRET_KEY is not set, you'll be prompted to generate one.

You should see:

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Application startup complete.

Step 7: Connect a Client

Option A: Reference Client

pip install flet
daemons client

Option B: Build Your Own

Connect via WebSocket to ws://127.0.0.1:8000/ws/game/auth.

Test Credentials:

• Username: testplayer1 / Password: testpass1
• Username: testplayer2 / Password: testpass2
