Enhance Middleware, Query Building, and Cryptocurrency Data Management

Description

Summary of Work

This pull request consolidates improvements across several critical components of our application, focusing on robustness, type safety, and comprehensive validation.

Key Objectives:

• Improve input validation and error handling
• Enhance type-safe query building for product searches
• Standardize cryptocurrency price data management
• Strengthen middleware validation mechanisms

The changes introduce more reliable validation strategies, improve type checking, and provide more consistent error handling across different application modules. These improvements will lead to more predictable and maintainable code, reducing potential runtime errors and improving overall system reliability.

Changes Made

Middleware and Validation Enhancements:

• Implemented comprehensive input validation for cryptocurrency-related endpoints
• Added type-safe validation logic for coin price, list, and details queries
• Enhanced error handling with clear, informative error messages

Query Builder Improvements:

• Refactored product search query builder with improved type safety
• Added support for more flexible price range filtering
• Ensured consistent query generation across different search scenarios

Data Management:

• Created standardized mock cryptocurrency price data structure
• Implemented robust data validation for cryptocurrency price information
• Improved type definitions for price-related interfaces

Tests and Verification

Test Coverage Improvements:

• Added comprehensive test suites for input validation middleware
• Created detailed tests for cryptocurrency price data validation
• Implemented thorough test cases for query builder functionality
• Ensured type safety and correct behavior across different input scenarios

Verification Steps:

• Validated all middleware validation scenarios
• Tested edge cases in query building and price data management
• Confirmed consistent error handling and type checking
• Verified that all tests pass across different modules
