Ticket: Dynamic Card Components with Live Data Integration #32
Description
Ticket: Dynamic Card Components with Live Data Integration
Feature Summary:
Implement dynamic card components for displaying live data, such as portfolio information, weather updates, crypto prices, and stock prices. Each card will fetch and display real-time data, with automatic updates, and be styled for optimal user interaction. The components should work seamlessly with Vercel’s serverless functions and support periodic updates for live streaming data.
User Stories:

Acceptance Criteria:
• Displays total portfolio value, individual asset balances, and USD values.
• Real-time data is fetched and displayed (e.g., portfolio data from Debank).
• Data updates automatically every minute.
• Card is styled with a clean design, using icons and tooltips.
Story Points: 5
- Weather Card with Live Updates
User Story:

• Weather data is fetched every 10 minutes from an external weather API.
• The card includes weather icons and relevant colors for better user experience.
Story Points: 8
- Crypto Price Card with Live Streaming Data
User Story:
As a user,
I want to see a crypto price card that displays live prices, 24-hour change percentages, and market data for popular cryptocurrencies (e.g., Bitcoin, Ethereum),
so that I can track the current market status of my investments.
Acceptance Criteria:
• Displays real-time prices for selected cryptocurrencies (e.g., Bitcoin, Ethereum).
• Includes 24-hour price change percentage, market cap, and volume.
• Card automatically updates every 5 seconds.
• The design includes currency symbols, percentages, and visual indicators for trends.
Story Points: 8
- Stock Price Card with Live Streaming Data
User Story:
As a user,
I want to see a stock price card that displays real-time stock prices, percentage changes, market cap, and trading volume for selected stocks,
so that I can track the current performance of my stock portfolio.
Acceptance Criteria:
• Displays latest stock prices, 24-hour change percentage, market cap, and volume.
• Data updates every 5 seconds.
• Includes stock tickers, percentages, and icons for quick reference.
Story Points: 5
- Notifications Card for Alerts and Updates
User Story:
As a user,
I want to see a notification card that alerts me about important updates, such as price alerts, new messages, or relevant changes,
so that I can stay informed and take action when needed.
Acceptance Criteria:
• Displays real-time alerts such as price changes, new messages, or other relevant notifications.
• Notifications are dynamically updated based on events (e.g., price triggers or new data).
• Card supports dismissing or clearing notifications.
Story Points: 3
Tasks:
1. Design Card Components:
• Create reusable and responsive card components for displaying data (using CSS Flexbox/Grid).
• Ensure cards are styled with icons, graphs, and dynamic data representations.
• Implement loading states and smooth animations for real-time updates.
2. Integrate Live Data Fetching:
• Implement API routes (e.g., for portfolio data, weather, crypto prices, stock data) using Vercel serverless functions.
• Set up automatic data fetching at regular intervals (e.g., every 5 seconds for crypto, every 10 minutes for weather).
• Implement caching with Vercel KV or Redis to reduce API load.
3. Handle Real-Time Data Updates:
• Implement live updates via periodic fetching or WebSockets.
• Display real-time price changes, stock price movements, and weather data.
4. Testing & Validation:
• Test the cards for responsiveness and performance across devices.
• Validate data fetching from external APIs and ensure proper error handling.
• Test real-time data updates and ensure data accuracy.
5. Deployment & Monitoring:
• Deploy to Vercel and monitor performance (including API load times, update intervals, and card rendering speed).
• Ensure error logging and failure recovery mechanisms are in place.
Dependencies:
• External APIs for portfolio (Debank), weather (OpenWeatherMap), crypto prices (CoinGecko or CoinMarketCap), and stock prices (Alpha Vantage or Yahoo Finance).
• Vercel serverless functions for fetching live data and caching.
Estimated Total Story Points: 29
This single ticket includes the necessary steps to implement the dynamic card components, which fetch and display real-time data from various APIs, with live streaming and automatic updates, ensuring a smooth and engaging user experience.
