Journal

A comprehensive set of React Native components for building journal and questionnaire interfaces in healthcare applications. The Journal module provides keyboard-aware forms, question-answer flows, and display components for past entries.

Key Features​

  • Keyboard-Aware Interface: Built with react-native-keyboard-controller for optimal mobile input experience
  • Compound Components: Flexible architecture using compound component patterns for customization
  • Healthcare-Focused: Designed for medical questionnaires, patient journaling, and health tracking
  • Material Design 3: Seamless integration with theming system for consistent visual design
  • Form Management: Input components optimized for text-based responses and multiline content

Components​

  • Answer - Interactive form container for journal entry creation
  • PastJournalCard - Display component for showing completed journal entries
  • TodayQuestionCard - Interactive card for displaying daily questions

Architecture​

The Journal module follows the compound component pattern, where each main component (Answer, PastJournalCard, TodayQuestionCard) serves as a container with specialized sub-components. This architecture provides:

  • Flexibility: Mix and match sub-components as needed
  • Consistency: Shared theming and styling across all components
  • Customization: Override styles while maintaining design system compliance
  • Type Safety: Full TypeScript support with proper prop definitions

Dependencies​

  • react-native-keyboard-controller - Keyboard-aware scrolling and toolbar
  • react-native-paper - Material Design components and theming
  • expo-linear-gradient - Gradient backgrounds for visual appeal
  • date-fns - Date formatting utilities (commonly used in examples)

Performance Considerations​

  • Keyboard Management: Automatic keyboard handling prevents input field obstruction
  • Scroll Optimization: KeyboardAwareScrollView provides smooth scrolling behavior
  • Memory Efficiency: Lightweight components with minimal overhead
  • Theme Integration: Efficient theme consumption without unnecessary re-renders
