🎯 Best Practices - TuskLang for C# - "Production Excellence"

Master the art of TuskLang in production - From code quality to operational excellence!

Best practices are the foundation of successful TuskLang implementations. Learn the patterns, strategies, and techniques that separate good configurations from great ones in production environments.

🎯 Best Practices Philosophy

"We Don't Bow to Any King"

- Code quality - Clean, maintainable, and readable configurations - Security first - Protect sensitive data and prevent vulnerabilities - Performance optimization - Efficient and scalable configurations - Operational excellence - Monitoring, logging, and troubleshooting - Team collaboration - Consistent patterns and shared knowledge

Why Best Practices Matter?

- Maintainability - Easy to understand and modify configurations - Security - Protect against data breaches and vulnerabilities - Performance - Optimize for speed and resource efficiency - Reliability - Reduce errors and improve system stability - Scalability - Handle growth and increased load

📝 Configuration Best Practices

1. Structure and Organization

Good: Well-organized configuration structure


Global variables at the top

$app_name: "TuskLangApp"
$version: "1.0.0"
$environment: @env("APP_ENV", "development")
Application configuration

[app]
name: $app_name
version: $version
environment: $environment
debug: @if($environment != "production", true, false)
Database configuration

[database]
primary {
    host: @env("DB_PRIMARY_HOST", "localhost")
    port: @env("DB_PRIMARY_PORT", "5432")
    name: @env("DB_PRIMARY_NAME", "tuskapp")
    user: @env("DB_PRIMARY_USER", "postgres")
    password: @env.secure("DB_PRIMARY_PASSWORD")
    ssl: @if($environment == "production", true, false)
}
Feature flags

[features]
cache_enabled: true
ml_enabled: @if($environment == "production", true, false)
debug_mode: @if($environment != "production", true, false)
Bad: Poorly organized configuration

[app]
name: "TuskLangApp"
version: "1.0.0"
debug: true
[database]
host: "localhost"
port: 5432
name: "tuskapp"
user: "postgres"
password: "secret"  # Hard-coded password!
[features]
cache_enabled: true
ml_enabled: false
debug_mode: true

2. Environment-Specific Configuration

Good: Environment-aware configuration

$environment: @env("APP_ENV", "development")
[server]
host: @if($environment == "production", "0.0.0.0", "localhost")
port: @if($environment == "production", 80, 8080)
ssl: @if($environment == "production", true, false)
[logging]
level: @if($environment == "production", "error", "debug")
format: @if($environment == "production", "json", "text")
file: @if($environment == "production", "/var/log/app.log", "console")
[security]
ssl_required: @if($environment == "production", true, false)
cors_origins: @if($environment == "production", ["https://myapp.com"], ["*"])

3. Security Best Practices

Good: Secure configuration practices

[security]

Use secure environment variables for sensitive data

database_password: @env.secure("DB_PASSWORD")
api_key: @env.secure("API_KEY")
jwt_secret: @env.secure("JWT_SECRET")
Encrypt sensitive configuration values

connection_string: @encrypt("${user}:${password}@${host}", "AES-256-GCM")
session_secret: @encrypt($session_secret_raw, "ChaCha20-Poly1305")
Validate required configuration

required_fields: @validate.required(["api_key", "database_password", "jwt_secret"])
// Good: Secure configuration service
public class SecureConfigurationService
{
    private readonly TuskLang _parser;
    private readonly IEncryptionProvider _encryptionProvider;
    private readonly IValidationProvider _validationProvider;
    
    public SecureConfigurationService(string masterKey)
    {
        _parser = new TuskLang();
        _encryptionProvider = new TuskEncryptionProvider(masterKey);
        _validationProvider = new TuskValidationProvider();
        
        _parser.SetEncryptionProvider(_encryptionProvider);
        _parser.SetValidationProvider(_validationProvider);
    }
    
    public async Task<Dictionary<string, object>> GetSecureConfigurationAsync(string filePath)
    {
        // Validate configuration before parsing
        if (!_parser.Validate(filePath))
        {
            throw new InvalidOperationException("Configuration validation failed");
        }
        
        // Parse configuration
        var config = _parser.ParseFile(filePath);
        
        // Validate required fields
        var requiredFields = config["security"]["required_fields"] as List<string>;
        foreach (var field in requiredFields)
        {
            if (string.IsNullOrEmpty(Environment.GetEnvironmentVariable(field)))
            {
                throw new InvalidOperationException($"Required environment variable {field} is not set");
            }
        }
        
        return config;
    }
}

4. Performance Optimization

Good: Performance-optimized configuration

[performance]

Cache expensive operations

expensive_query: @cache("5m", @query("SELECT COUNT(*) FROM large_table"))
api_response: @cache("30s", @http("GET", "https://api.example.com/data"))
Adaptive caching based on load

adaptive_cache: @cache(@if(@metrics("cpu_usage", 0) > 80, "30s", "5m"), @query("SELECT * FROM heavy_table"))
Batch operations for efficiency

batch_queries: @query.batch([
    "SELECT COUNT(*) FROM users",
    "SELECT COUNT(*) FROM orders",
    "SELECT COUNT(*) FROM products"
])
Connection pooling

database_pool {
    max_open_conns: @if($environment == "production", 100, 20)
    max_idle_conns: @if($environment == "production", 50, 10)
    conn_max_lifetime: "5m"
}
// Good: Performance-optimized service
public class OptimizedConfigurationService
{
    private readonly TuskLang _parser;
    private readonly ICacheProvider _cacheProvider;
    private readonly IDatabaseAdapter _databaseAdapter;
    
    public OptimizedConfigurationService()
    {
        _parser = new TuskLang();
        
        // Multi-layer caching
        _cacheProvider = new MultiLayerCacheProvider(new ICacheProvider[]
        {
            new MemoryCacheProvider(),           // L1: In-memory cache
            new RedisCacheProvider(new RedisConfig
            {
                Host = "localhost",
                Port = 6379
            }),                                  // L2: Redis cache
            new DatabaseCacheProvider()          // L3: Database cache
        });
        
        // Optimized database adapter
        _databaseAdapter = new PostgreSQLAdapter(new PostgreSQLConfig
        {
            Host = "localhost",
            Database = "myapp"
        }, new PoolConfig
        {
            MaxOpenConns = 100,
            MaxIdleConns = 50,
            ConnMaxLifetime = 300000,
            ConnMaxIdleTime = 60000
        });
        
        _parser.SetCacheProvider(_cacheProvider);
        _parser.SetDatabaseAdapter(_databaseAdapter);
    }
    
    public async Task<Dictionary<string, object>> GetOptimizedConfigurationAsync(string filePath)
    {
        // Preload frequently accessed data
        await PreloadCacheAsync();
        
        // Parse with optimizations
        return _parser.ParseFile(filePath);
    }
    
    private async Task PreloadCacheAsync()
    {
        var preloadTasks = new[]
        {
            PreloadUserCountAsync(),
            PreloadActiveUsersAsync(),
            PreloadSystemMetricsAsync()
        };
        
        await Task.WhenAll(preloadTasks);
    }
}

🔒 Security Best Practices

1. Secrets Management

// Good: Secure secrets management

{
    private readonly IKeyVaultClient _keyVaultClient;
    private readonly ILogger<SecureSecretsService> _logger;
    
    public SecureSecretsService(IKeyVaultClient keyVaultClient, ILogger<SecureSecretsService> logger)

2. Input Validation
