🚀 Best Practices

1. Security Implementation

// ✅ Good: Comprehensive security implementation
String goodSecurity = """
    secure_config: {
        api_key: @env.secure("API_KEY")
            .encrypt("AES-256-GCM")
            .validate(key -> key.length() >= 32, "API key too short")
            .rate_limit("100/minute")
    }
    """;

// ❌ Bad: Inadequate security String badSecurity = """ secure_config: { api_key: @env("API_KEY") } """;

2. Input Validation

// ✅ Good: Comprehensive input validation
String goodValidation = """
    user_input: @env("USER_INPUT")
        .sanitize_input()
        .validate(input -> input.length() < 1000, "Input too long")

        .escape_html()
    """;

// ❌ Bad: No input validation String badValidation = """ user_input: @env("USER_INPUT") """;

3. Rate Limiting

// ✅ Good: Appropriate rate limiting
String goodRateLimiting = """
    api_operation: @query.secure("SELECT * FROM users")
        .validate_sql()
        .rate_limit("100/minute")
        .sanitize_input()
    """;

// ❌ Bad: No rate limiting String badRateLimiting = """ api_operation: @query("SELECT * FROM users") """;
