Enhance Cryptocurrency Data Service: Robust Caching, Validation, and API Improvements

Description

Summary of Work

This pull request consolidates multiple improvements to our cryptocurrency data service, focusing on enhancing reliability, performance, and maintainability.

Key Objectives:

• Implement a more robust and flexible caching mechanism
• Strengthen input validation for cryptocurrency-related endpoints
• Improve error handling and middleware capabilities
• Enhance overall system resilience and data integrity

The changes aim to create a more scalable and secure cryptocurrency price tracking service, with particular emphasis on modular design and comprehensive validation strategies.

Changes Made

Architectural Improvements:

• Implemented singleton CacheService with enhanced configuration options
• Created centralized input validation middleware
• Added comprehensive error handling mechanisms

Caching Enhancements:

• Developed type-safe cache configuration interface
• Implemented flexible cache initialization with default and custom settings
• Added cache statistics and management methods

Validation Improvements:

• Created robust input validation for cryptocurrency-related endpoints
• Implemented comprehensive coin data validation
• Added support for flexible parameter checking with meaningful error responses

Middleware Developments:

• Enhanced route-level input validation
• Improved error handling and response generation
• Created reusable validation utilities

Tests and Verification

Test Coverage Improvements:

• Added unit tests for cache service configuration
• Implemented comprehensive input validation test suite
• Verified error handling and edge case scenarios
• Expanded mock data to support more diverse testing scenarios

Verification Steps:

• Manually tested all validation middleware
• Confirmed cache service behaves correctly under various configurations
• Validated error responses and input sanitization
• Ensured compatibility with existing system components
