Enhance Error Handling and File Access Middleware for CDN File Service

Description

Summary of Work

Overview

This pull request consolidates improvements to our CDN file service's error handling and access control mechanisms, focusing on robust error management, improved security, and enhanced developer experience.

Motivation

As our file service grows, we need a more sophisticated approach to:

• Provide clear and secure error responses
• Implement comprehensive file access controls
• Create a standardized error handling framework
• Improve system reliability and debugging capabilities

Key Benefits

• Centralized error response utility
• Granular file access permission checks
• Standardized error logging
• Improved security through explicit error handling
• Enhanced type safety with TypeScript

Changes Made

Error Handling Improvements:

• Implemented custom FileAccessError for precise file access error tracking
• Created centralized error response utility with standardized error types
• Added comprehensive error logging mechanism

File Access Security:

• Developed checkFileAccess utility for safe file permission validation
• Enhanced middleware to handle various file-related error scenarios
• Implemented granular error responses for different access violation types

Architectural Enhancements:

• Integrated TypeScript for improved type checking
• Created modular error handling utilities
• Established consistent error response patterns across the service

Tests and Verification

Test Coverage Verification:

• Added comprehensive unit tests for error response utilities
• Implemented test cases for file access permission scenarios
• Verified error handling middleware functionality
• Tested various error type responses and logging mechanisms
• Ensured robust error handling across different access scenarios

Test Scenarios Covered:

• File access permission checks
• Error response generation
• Error type mapping
• Logging utility functionality
• Edge case error handling
