pip install -e .[dev]
```
4. **Set up environment configuration:**
```bash
cp .env.template .env
# Edit .env with your specific configuration
```
5. **Start Redis (if not running):**
```bash
# On Ubuntu/Debian:
sudo systemctl start redis-server
# On macOS with Homebrew:
brew services start redis
# Using Docker:
docker run -d -p 6379:6379 redis:alpine
```
## Development Workflow
### Code Quality Checks
```bash
# Format code
black src/ tests/
isort src/ tests/
# Lint code
ruff check src/ tests/
# Type checking
mypy src/
# Run all quality checks
black src/ tests/ && isort src/ tests/ && ruff check src/ tests/ && mypy src/
```
### Testing
```bash
# Run tests
pytest
# Run tests with coverage
pytest --cov=random_access --cov-report=html
# Run specific test file
pytest tests/test_security.py
```
### Running the Application
```bash
# Development server with auto-reload
random-access-server
# Or with uvicorn directly
uvicorn random_access.main:app --reload --host 0.0.0.0 --port 8000
```
### Building the Package
```bash
# Build source and wheel distributions
python -m build
# Install from local build
pip install dist/random_access-*.whl
```
## IDE Configuration
### VS Code

# Random Access
This is a work-in-progess, all will be revealed soon™!

**The backend API that powers Hack Club's Random Access You Ship, We Ship program.**
Random Access is a Hack Club You Ship, We Ship (YSWS) program, specifically focused on high school students building games that share items between them. This API makes cross-game item sharing possible, letting players carry their earned items between different games and creating a shared gaming universe where progress transcends individual games.
**Complete your game with Random Access integration and earn a high-quality game controller!**
## For Game Developers
Whether you're building your first game or you're an experienced developer, integrating with Random Access gets you a **game controller** when you complete your project! This API makes it easy to add cross-game item sharing to your game and qualify for the YSWS reward.
## How It Works for Players
1. **Earn items** in any participating game (weapons, skins, achievements, etc.)
2. **Items are saved** to your cross-game inventory automatically
3. **Use items** in other participating games - your progress follows you
4. **Discover new games** through the shared item ecosystem
## Getting Started (Game Developers)
### 1. Use the Hosted API
No setup required! The Random Access API is hosted at **https://random-access.hackclub.com** - just start making requests.
🔗 **Live API Documentation**: https://random-access.hackclub.com/docs
### 2. Authenticate Your Game
```javascript
// Example: Getting a session token for your game
const response = await fetch('https://random-access.hackclub.com/auth/login', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
username: 'player123',
// ... auth details
})
});
const { token } = await response.json();
```
### 3. Give Players Items
```javascript
// Example: Player earned a "Fire Sword" in your game
await fetch('https://random-access.hackclub.com/items', {
method: 'POST',
headers: {
'Authorization': `Bearer ${token}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
name: 'Fire Sword',
type: 'weapon',
rarity: 'epic',
game_source: 'your-game-name'
})
});
```
### 4. Let Players Use Items from Other Games
```javascript
// Example: Get all items this player has earned across all games
const items = await fetch('https://random-access.hackclub.com/items', {
headers: { 'Authorization': `Bearer ${token}` }
}).then(r => r.json());
// Now player can use their "Magic Shield" from another game!
items.forEach(item => {
if (item.type === 'shield') {
// Add to player's inventory in your game
}
});
```
## Game Integration Examples
### Unity (C#)
```csharp
// Give player an item
var item = new { name = "Lightning Bolt", type = "spell", rarity = "rare" };
var json = JsonConvert.SerializeObject(item);
var content = new StringContent(json, Encoding.UTF8, "application/json");
await httpClient.PostAsync("https://random-access.hackclub.com/items", content);
```
### Godot (GDScript)
```gdscript
# Get player's items from all games
var http_request = HTTPRequest.new()
add_child(http_request)
http_request.request("https://random-access.hackclub.com/items", headers)
```
### Web Games (JavaScript)
```javascript
// Works with any web framework - React, Vue, vanilla JS, etc.
const playerItems = await fetch('https://random-access.hackclub.com/items', {
headers: { 'Authorization': `Bearer ${token}` }
}).then(r => r.json());
```
### Python Games (pygame, etc.)
```python
import requests
# Perfect for game jams and quick prototypes
response = requests.get('https://random-access.hackclub.com/items', headers=headers)
items = response.json()
```
## What Players Experience
Each game interprets shared items in ways that fit their gameplay - weapons stay weapons, armor stays armor, but players get to carry their achievements across the entire ecosystem.
## API Overview
🔗 **Live API Docs**: https://random-access.hackclub.com/docs
- **`/auth/*`** - Player login/logout and session management
- **`/items/*`** - Create, read, update items that players earn
- **`/users/*`** - Player profiles and cross-game statistics
- **`/system/*`** - Health checks and status monitoring
The API is RESTful, returns JSON, and includes detailed examples for every endpoint.
## Built for Real Games
- **Fast**: Redis caching means your game gets instant responses
- **Reliable**: Built-in rate limiting prevents abuse and ensures fair play
- **Secure**: Player data is protected with proper authentication
- **Scalable**: Handles multiple games and thousands of players
- **Cross-Platform**: Works with web games, mobile apps, desktop games, etc.
## Contributing to the Ecosystem
Show off what you built with the Random Access program:
1. **Share Your Game**: Let the community see what you created!
2. **Help Other Developers**: Answer questions and share tips
3. **Suggest Item Types**: What kinds of items would be cool to share between games?
4. **Test the API**: Report any issues you find while building
## About the Random Access You Ship, We Ship Program
Random Access is one of Hack Club's You Ship, We Ship (YSWS) programs, specifically designed for high school students building interconnected games. **Ship a completed game that integrates with this API and earn a game controller!**
This API provides the technical foundation you need to focus on making an awesome game instead of worrying about backend infrastructure. The cross-game item sharing functionality is already built - you just need to integrate it into your game to qualify for the reward.
## Contributing to the API
