Vendor Integration Guide

Adding New Vendors

1. Create Vendor Adapter

Create a new file in src/vendors/YourVendor.js:

import { BaseVendorAdapter } from '../core/BaseVendorAdapter';

class YourVendor extends BaseVendorAdapter {
  constructor(config = {}) {
    super('Your Vendor Name', config);
  }

  getCapabilities() {
    return {
      marketData: true,      // Can fetch market data
      orderManagement: false, // Cannot place orders
      portfolio: true,       // Can get portfolio data
      analytics: false,      // No analytics
      realtime: true         // Supports real-time data
    };
  }

  async connect() {
    // Your connection logic
    this.isConnected = true;
    return { success: true };
  }

  async getMarketData(symbol) {
    // Your market data implementation
    return {
      success: true,
      data: { symbol, price: 100, change: 5 }
    };
  }

  // Implement other methods as needed
}

export default YourVendor;

2. Register Vendor

In src/App.jsx, add your vendor:

import YourVendor from './vendors/YourVendor';

// In useEffect
VendorManager.registerVendor('yourVendorId', new YourVendor());

3. Vendor Capabilities

The UI automatically adapts based on vendor capabilities:

  • Tabs only show if vendor supports the feature
  • Error boundaries prevent crashes
  • Graceful fallbacks for missing features

4. API Integration

Each vendor can have completely different:

  • API endpoints
  • Authentication methods
  • Data formats
  • Available features

The BaseVendorAdapter provides error handling and standardized interface.

Architecture Benefits

  • Fault Isolation: Vendor failures don't crash the UI
  • Dynamic Capabilities: UI adapts to vendor features
  • Easy Extension: Add vendors without changing core UI
  • Consistent Interface: All vendors use same base methods
  • Error Recovery: Built-in retry mechanisms
