The Touch Stay analytics dashboard allows property owners to view guest engagement metrics alongside weather data for their digital guidebooks. The current implementation has evolved organically as new data sources were added, resulting in a complex, monolithic component with significant prop drilling and mixed concerns.
The WeatherDashboard.vue component has grown, handling API calls, data transformation, visualization rendering, date filtering, and export functionality. This has led to maintenance challenges, performance issues with unnecessary re-renders, and difficulty in adding new metrics or visualization types.
Your task is to refactor this component to improve maintainability, performance, and extensibility while preserving all existing functionality.
- Split the monolithic component into smaller, focused components with clear responsibilities
- Extract data fetching and transformation logic into composables
- Eliminate prop drilling by implementing a more efficient state management approach
- Improve performance by optimizing rendering and preventing unnecessary re-renders
- Convert from Options API to Composition API with
<script setup>syntax - Ensure proper TypeScript typing throughout the refactored code
- Maintain all existing functionality and visual appearance
You've been assigned to refactor the analytics dashboard component as part of a larger initiative to improve code quality and maintainability across the Touch Stay codebase. The current implementation works but has become difficult to extend and maintain as new analytics features are requested.
The product team needs to add several new metrics and visualization types in the coming sprints, so your refactoring should make it easy to add new metrics without modifying existing code (following the Open/Closed Principle).
-
How did you decide which parts of the component to extract into separate components or composables? What principles guided your decision-making process?
-
Explain your approach to state management in the refactored solution. What are the trade-offs between using Pinia, provide/inject, or composables for sharing state in this specific case?
-
How would your refactored architecture support adding new visualization types or metrics without modifying existing code? What patterns did you implement to ensure extensibility?
-
The original component mixes UI concerns with data fetching and transformation. How does your refactoring improve separation of concerns, and what benefits does this bring to testing and maintenance?
-
What performance optimizations did you implement in your refactored solution? How would you measure the performance impact of your changes?
