Enhance CDN Middleware: Robust Path Validation and Rate Limiting

Description

Summary of Work

This pull request introduces a comprehensive enhancement to our CDN middleware, focusing on improving security, flexibility, and reliability of file serving and request management.

Key Objectives:

• Implement secure and dynamic CDN path validation
• Create flexible rate limiting middleware
• Improve overall system resilience and configurability

The changes address critical infrastructure needs by providing:

• Robust file path security mechanisms
• Configurable rate limiting strategies
• Dynamic directory management
• Enhanced error handling and logging capabilities

These improvements will help prevent potential security vulnerabilities while providing administrators with greater control over CDN file serving and request management.

Changes Made

Architectural Improvements:

• Enhanced CDN configuration with dynamic path handling
• Implemented flexible rate limiting middleware
• Added comprehensive path validation mechanisms

Security Enhancements:

• Prevent directory traversal attacks
• Dynamically create and validate file paths
• Implement configurable rate limiting controls

Configuration Updates:

• Added support for custom CDN directory configuration
• Enabled dynamic directory creation
• Improved error handling and logging mechanisms

Dependency Management:

• Updated package.json with required dependencies
• Added TypeScript type definitions
• Ensured compatibility with existing test frameworks

Tests and Verification

Test Coverage Improvements:

• Verified CDN path validation across multiple scenarios
• Implemented tests for nested and dynamic directory handling
• Created mock rate limiting middleware for consistent testing
• Ensured comprehensive path security validation
• Added error handling test cases

Verification Steps:

• Ran full test suite across all middleware components
• Validated path validation logic
• Confirmed rate limiting middleware structure
• Checked directory creation and management functionality
