- Introduced a debugging environment configuration in app.js, allowing for dynamic API endpoint selection based on the environment. - Implemented lazy loading for chapter parts in chapters.js, improving performance by only fetching necessary data. - Updated UI elements in chapters.wxml to reflect changes in chapter loading and added loading indicators. - Enhanced error handling and data management for chapter retrieval, ensuring a smoother user experience. - Added functionality for switching API environments in settings.js, visible only in development mode.
