## Phase Research: Setup & Foundation ### Standard Stack - React.js for component-based UI development - Tailwind CSS for styling and responsive design - LocalStorage API for data persistence - HTML5 Drag and Drop API for task reorganization ### Architecture Patterns - Component-based architecture with reusable calendar components - State management for tasks and calendar navigation - Modular design allowing for future phase extensions ### Don't Hand-Roll - Do not implement custom calendar rendering logic - use proven libraries - Do not create custom drag and drop implementation - use established APIs - Do not build custom data persistence layer - leverage localStorage ### Common Pitfalls - Forgetting to handle edge cases in date calculations - Improper state management leading to UI inconsistencies - Not accounting for time zones in date handling - Overcomplicating the UI too early in development ### Code Examples - Basic React component structure for calendar views - localStorage usage patterns for task persistence - Event delegation for handling drag and drop operations
