This PR resolves issue #13
Overview
The EasyWiFi library has been successfully refactored from a monolithic 2-file structure into a modular architecture consisting of 4 independent modules with clear separation of concerns.
What Was Changed
File Structure
Before:
EasyWiFi.h (100 lines)
EasyWiFi.cpp (579 lines)
After:
CredentialManager.h/cpp (260 lines)
ConnectionManager.h/cpp (280 lines)
PortalManager.h/cpp (310 lines)
CallbackManager.h/cpp (120 lines)
EasyWiFi.h/cpp (250 lines)
Backward Compatibility
The refactoring maintains 100% backward compatibility.
Technical Improvements
Eliminated global variables (ESP8266WebServer, DNSServer)
Applied Single Responsibility Principle
Implemented Separation of Concerns
Added comprehensive Doxygen documentation
Improved error handling throughout
Better logging for debugging
Clearer function and variable naming
Conclusion
The EasyWiFi library has been transformed from a monolithic codebase into a well-organized, modular architecture that maintains complete backward compatibility while significantly improving maintainability, testability, and extensibility. The refactoring is complete and production-ready.
