# Changelog

## 2025-08-15 - 5.3.0 - feat(AppData)
Refactor AppData class for declarative env mapping and enhanced static helpers

- Introduced a singleton Qenv provider to optimize environment variable resolution.
- Centralized type conversion logic with utility functions for boolean, JSON, base64, number, and string conversions.
- Replaced complex switch statements with a composable, declarative mapping pipeline for processing envMapping.
- Enhanced logging during AppData initialization to clearly report key processing and overwrite operations.
- Added new static helper methods for environment variable access (valueAsBoolean, valueAsJson, valueAsBase64, valueAsString, valueAsNumber).
- Fixed boolean conversion issues and ensured backward compatibility with the deprecated 'ephermal' option.

## 2025-08-15 - 5.2.0 - feat(AppData)
Major refactoring of AppData class for improved elegance and maintainability

- **New Features:**
  - Added static helper methods for direct environment variable access:
    - `AppData.valueAsBoolean()` - Convert env vars to boolean
    - `AppData.valueAsJson()` - Parse env vars as JSON
    - `AppData.valueAsBase64()` - Decode base64 env vars
    - `AppData.valueAsString()` - Get env vars as string
    - `AppData.valueAsNumber()` - Parse env vars as number
  - Enhanced logging for AppData initialization and key processing:
    - Shows which storage type is being used (custom, ephemeral, auto-selected)
    - Logs each key being processed with its spec type
    - Reports success/failure for each key with type information
    - Provides summary statistics of processed keys

- **Architecture Improvements:**
  - Replaced 100+ line switch statement with declarative pipeline architecture
  - Introduced centralized type converters and transform registry
  - Implemented composable transform pipeline: `parseMappingSpec()` → `resolveSource()` → `applyTransforms()`
  - Added singleton Qenv provider to reduce allocations
  - Reduced code complexity by ~70% while maintaining 100% backward compatibility

- **Bug Fixes:**
  - Fixed boolean conversion to properly handle both string and boolean inputs
  - Added `ephemeral` option (correctly spelled) while maintaining backward compatibility with deprecated `ephermal`

- **Performance:**
  - Optimized environment variable resolution with shared Qenv instance
  - Reduced object allocations in static helpers
