API Directives in TuskLang - Bash Guide

🔌 Revolutionary API Configuration

API directives in TuskLang transform your configuration files into intelligent API gateways. No more separate API documentation or complex routing configurations - everything lives in your TuskLang configuration with dynamic endpoints, automatic validation, and intelligent response handling.

> "We don't bow to any king" - TuskLang API directives break free from traditional API framework constraints and bring modern API capabilities to your Bash applications.

🚀 Core API Directives

Basic API Setup

#api: /api/v1                 # API base path
#api-version: 1.0             # API version
#api-docs: /docs              # API documentation endpoint
#api-spec: openapi            # API specification format
#api-auth: jwt                # API authentication method
#api-rate-limit: 100/min      # API rate limiting

Advanced API Configuration

#api-cors: "*"                # API CORS policy
#api-timeout: 30              # API request timeout
#api-cache: redis             # API response caching
#api-logging: true            # API request logging
#api-metrics: true            # API metrics collection
#api-validation: true         # Request/response validation

🚨 Troubleshooting API Directives

Common Issues and Solutions

1. Authentication Failures

Debug authentication issues
debug_authentication() {
    local headers="$1"
    
    echo "Debugging authentication..."
    echo "Headers: $headers"
    echo "Auth method: $API_AUTH_METHOD"
    
    case "$API_AUTH_METHOD" in
        "jwt")
            local auth_header=$(echo "$headers" | grep -i "authorization:")
            echo "Auth header: $auth_header"
            
            if [[ -n "$auth_header" ]]; then
                local token="${auth_header#Bearer }"
                echo "Token: ${token:0:20}..."
                
                # Decode JWT header
                IFS='.' read -r header payload signature <<< "$token"
                local decoded_header=$(echo "$header" | tr '_-' '/+' | base64 -d 2>/dev/null)
                echo "JWT header: $decoded_header"
            fi
            ;;
        "api-key")
            local api_key=$(echo "$headers" | grep -i "x-api-key:" | cut -d' ' -f2-)
            echo "API key: ${api_key:0:10}..."
            ;;
    esac
}

2. Rate Limiting Issues

Debug rate limiting
debug_rate_limiting() {
    local client_id="$1"
    
    echo "Debugging rate limiting..."
    echo "Client ID: $client_id"
    echo "Rate limit: $API_RATE_LIMIT"
    
    local current_count=$(get_api_request_count "$client_id")
    echo "Current count: $current_count"
    
    local cache_key="api_rate_limit:$client_id"
    echo "Cache key: $cache_key"
    
    # Check cache directly
    local cached_value=$(get_cache_value "$cache_key")
    echo "Cached value: $cached_value"
}

3. Validation Errors

Debug validation issues
debug_validation() {
    local method="$1"
    local path="$2"
    local body="$3"
    
    echo "Debugging validation..."
    echo "Method: $method"
    echo "Path: $path"
    echo "Body: $body"
    
    # Validate JSON format
    if [[ -n "$body" ]]; then
        if echo "$body" | jq . >/dev/null 2>&1; then
            echo "JSON format: Valid"
        else
            echo "JSON format: Invalid"
            echo "JSON error: $(echo "$body" | jq . 2>&1)"
        fi
    fi
    
    # Check path format
    if [[ "$path" =~ ^/[a-zA-Z0-9/_-]*$ ]]; then
        echo "Path format: Valid"
    else
        echo "Path format: Invalid"
    fi
}

🔒 Security Best Practices

API Security Checklist

Security validation
validate_api_security() {
    echo "Validating API security configuration..."
    
    # Check authentication
    if [[ "$API_AUTH_METHOD" != "none" ]]; then
        echo "✓ Authentication enabled: $API_AUTH_METHOD"
    else
        echo "⚠ No authentication configured"
    fi
    
    # Check rate limiting
    if [[ -n "$API_RATE_LIMIT" ]]; then
        echo "✓ Rate limiting configured: $API_RATE_LIMIT"
    else
        echo "⚠ Rate limiting not configured"
    fi
    
    # Check CORS policy
    if [[ "$api_cors" != "*" ]]; then
        echo "✓ CORS restricted: $api_cors"
    else
        echo "⚠ CORS set to '*' - consider restricting"
    fi
    
    # Check request validation
    if [[ "$api_validation" == "true" ]]; then
        echo "✓ Request validation enabled"
    else
        echo "⚠ Request validation not enabled"
    fi
    
    # Check HTTPS
    if [[ "$ssl_enabled" == "true" ]]; then
        echo "✓ HTTPS enabled"
    else
        echo "⚠ HTTPS not enabled - consider for production"
    fi
}

📈 Performance Optimization Tips

API Performance Checklist

Performance validation
validate_api_performance() {
    echo "Validating API performance configuration..."
    
    # Check caching
    if [[ -n "$api_cache" ]]; then
        echo "✓ Response caching enabled: $api_cache"
    else
        echo "⚠ Response caching not configured"
    fi
    
    # Check timeout
    if [[ -n "$api_timeout" ]]; then
        echo "✓ Request timeout configured: ${api_timeout}s"
    else
        echo "⚠ Request timeout not configured"
    fi
    
    # Check metrics
    if [[ "$api_metrics" == "true" ]]; then
        echo "✓ Metrics collection enabled"
    else
        echo "⚠ Metrics collection not enabled"
    fi
    
    # Check logging
    if [[ "$api_logging" == "true" ]]; then
        echo "✓ Request logging enabled"
    else
        echo "⚠ Request logging not enabled"
    fi
}
