🚀 Getting Started

This project is a static web application and does not require a complex build process. You can run it with any local web server.

Prerequisites

To run the application with live data, you will need a free API key from Alpha Vantage.

1. Alpha Vantage API Key: Get a free key from Alpha Vantage.

The app will function in a robust offline "fallback mode" with simulated data if a key is not provided.

Installation & Configuration

1. Clone the repository:

   git clone https://github.com/your-username/robo-advisor-super-app.git
   cd robo-advisor-super-app

2. Configure API Key:

   • Open the process.env.js file in the root directory.
   • Replace the placeholder value for ALPHAVANTAGE_API_KEY with your actual key.

   // process.env.js
   
   // Replace with your Alpha Vantage API Key
   export const ALPHAVANTAGE_API_KEY = 'YOUR_ALPHAVANTAGE_API_KEY_HERE';

3. Run the application: Use a simple local server to host the files. A popular choice is the Live Server extension for Visual Studio Code.

   • Install the extension.
   • Right-click index.html and select "Open with Live Server".

The application should now be running in your browser!

🏛️ Architecture & Key Concepts

Service-Oriented Architecture

The application logic is cleanly separated into a services directory, abstracting away the data-fetching from the UI components.

• financialDataService.ts: The data hub of the app. It handles all API calls to Alpha Vantage and the SEC for fetching market data.
• fallbackData.ts: This service provides realistic, simulated data for every API call in the application. It is used automatically if an API key is not provided, ensuring a seamless user experience for demos and development.
• cacheService.ts: A simple in-memory cache with a Time-to-Live (TTL) reduces redundant API calls for data that doesn't change frequently (e.g., news, stock analysis), improving performance and saving API quota.

Data Flow & Polling

The app stays up-to-date with a smart polling mechanism initiated in App.tsx which fetches prices more frequently for the user's active portfolio (every 30 seconds) than for their watchlist (every 2 minutes).
