🏗️ Architecture Overview​

NeuroLink uses a Factory Pattern architecture that provides:

Core Components​

graph TD
    A[NeuroLink SDK] --> B[Provider Factory]
    B --> C[BaseProvider]
    C --> D[OpenAI Provider]
    C --> E[Google AI Provider]
    C --> F[Anthropic Provider]
    C --> G[Other Providers]

    A --> H[MCP System]
    H --> I[Built-in Tools]
    H --> J[Custom Tools]
    H --> K[External Servers]

    A --> L[Analytics System]
    A --> M[Evaluation System]
    A --> N[Streaming System]

Design Principles​

  • Unified Interface: All providers implement the same AIProvider interface
  • Type Safety: Full TypeScript support with strict typing
  • Extensibility: Easy to add new providers and tools
  • Performance: Optimized for production use
  • Reliability: Comprehensive error handling and fallbacks

🧪 Testing Philosophy​

NeuroLink uses a multi-layered testing approach:

Test Categories​

  1. Unit Tests - Individual component testing
  2. Integration Tests - Provider and tool interaction
  3. End-to-End Tests - Complete workflow validation
  4. Performance Tests - Speed and resource usage
  5. Regression Tests - Prevent breaking changes
