Environment Configuration

Create environment files for each component:

# Whisky API

Solana Configuration

# Set Solana to devnet for development
solana config set --url devnet

# Create a new keypair for testing
solana-keygen new --outfile ~/.config/solana/devnet.json

# Set the keypair as default
solana config set --keypair ~/.config/solana/devnet.json

# Request airdrop for testing
solana airdrop 2

Smart Contract Development

Anchor Program

anchor test

Program Configuration

// Anchor.toml configuration
[features]
seeds = false
skip-lint = false

[programs.devnet]
whisky = "YOUR_PROGRAM_ID"

[registry]
url = "https://api.apr.dev"

[provider]
cluster = "devnet"
wallet = "~/.config/solana/devnet.json"

Development Workflow

1. Local Development

# Start all services locally
npm run dev:all

# Or start individual services
npm run dev:api
npm run dev:explorer
npm run dev:sdk

2. Testing

# Run all tests
npm run test:all

# Run specific test suites
npm run test:unit
npm run test:integration
npm run test:e2e

3. Code Quality

# Run linting
npm run lint

# Run type checking
npm run type-check

# Run formatting
npm run format

Debugging

Smart Contract Debugging

// Enable debug logging
const DEBUG = process.env.NODE_ENV === 'development';

if (DEBUG) {
  console.log('Transaction:', transaction);
  console.log('Accounts:', accounts);
  console.log('Instruction data:', instructionData);
}

API Debugging

// Enable API debug mode
const api = new WhiskyAPI({
  baseUrl: 'http://localhost:3000',
  apiKey: 'your-api-key',
  debug: true
});

Frontend Debugging

// Enable React DevTools
import { WhiskyProvider } from '@whisky-gaming/ui';

<WhiskyProvider debug={true}>
  <YourApp />
</WhiskyProvider>

Performance Optimization

Database Optimization

-- Create indexes for frequently queried fields
CREATE INDEX idx_games_pool ON games(pool_address);
CREATE INDEX idx_games_player ON games(player_address);
CREATE INDEX idx_games_time ON games(timestamp);

Caching Strategy

// Redis caching for API responses
import Redis from 'ioredis';

const redis = new Redis({
  host: 'localhost',
  port: 6379
});

async function getCachedData(key: string) {
  const cached = await redis.get(key);
  if (cached) {
    return JSON.parse(cached);
  }
  
  const data = await fetchData(key);
  await redis.set(key, JSON.stringify(data), 'EX', 300);
  return data;
}

Bundle Optimization

// Tree shaking for smaller bundles
import { WhiskySDK } from '@whisky-gaming/core';
// Instead of importing the entire package

// Use dynamic imports for code splitting
const WhiskyProvider = lazy(() => import('@whisky-gaming/ui').then(module => ({ default: module.WhiskyProvider })));

Security Best Practices

Input Validation

// Validate all user inputs
function validateGameParams(params: GameParams): boolean {
  if (params.wager <= 0) return false;
  if (params.bet.length === 0) return false;
  if (params.bet.some(weight => weight <= 0)) return false;
  return true;
}

Error Handling

// Comprehensive error handling
try {
  const result = await sdk.playGame(gameParams);
} catch (error) {
  if (error instanceof WhiskyError) {
    // Handle protocol-specific errors
    handleWhiskyError(error);
  } else if (error instanceof SolanaError) {
    // Handle Solana-specific errors
    handleSolanaError(error);
  } else {
    // Handle unexpected errors
    console.error('Unexpected error:', error);
  }
}

Transaction Safety

// Always simulate transactions before sending
const transaction = await sdk.buildPlayGameTransaction(gameParams);
const simulation = await connection.simulateTransaction(transaction);

if (simulation.value.err) {
  throw new Error(`Transaction simulation failed: ${simulation.value.err}`);
}

const signature = await sdk.sendTransaction(transaction);

Monitoring & Logging

Application Logging

// Structured logging
import winston from 'winston';

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'error.log', level: 'error' }),
    new winston.transports.File({ filename: 'combined.log' })
  ]
});

logger.info('Game started', {
  player: playerAddress,
  wager: wagerAmount,
  pool: poolAddress
});

Performance Monitoring

// Monitor API response times
const startTime = Date.now();
const response = await api.getStats();
const responseTime = Date.now() - startTime;

logger.info('API response time', {
  endpoint: '/stats',
  responseTime,
  status: response.status
});

Error Tracking

// Track errors with context
try {
  await sdk.playGame(gameParams);
} catch (error) {
  logger.error('Game failed', {
    error: error.message,
    player: playerAddress,
    wager: wagerAmount,
    pool: poolAddress,
    timestamp: new Date().toISOString()
  });
}

Deployment

# Run staging tests
npm run test:staging

# Monitor staging environment
npm run monitor:staging

Production Deployment

# Deploy to production
npm run deploy:production

# Run production tests
npm run test:production

# Monitor production environment
npm run monitor:production

CI/CD Pipeline

# GitHub Actions workflow
name: Deploy

on:
  push:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with:
          node-version: '16'
      - run: npm ci
      - run: npm test
      - run: npm run lint

  deploy:
    needs: test
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: npm run deploy:production

Troubleshooting

Common Issues

Build Failures

# Clear node_modules and reinstall
rm -rf node_modules package-lock.json
npm install

# Clear cache
npm cache clean --force

Test Failures

# Run tests with verbose output
npm test -- --verbose

# Run specific test file
npm test -- --testNamePattern="Game Flow"

Deployment Issues

# Check environment variables
echo $NODE_ENV
echo $DATABASE_URL
echo $API_KEY

# Check logs
npm run logs
