Core Features

​

🔐 Authentication & Security

import { Suada } from '@suada/node';

const suada = new Suada({
  apiKey: process.env.SUADA_API_KEY,
  privacyMode: true  // Optional enhanced security
});

​

🤖 LangChain Integration

import { Suada } from '@suada/node';
import { AgentExecutor, createOpenAIFunctionsAgent } from 'langchain/agents';
import { ChatOpenAI } from 'langchain/chat_models/openai';

const suada = new Suada({
  apiKey: process.env.SUADA_API_KEY
});

const suadaTool = suada.createTool({
  name: 'business_analyst',
  description: 'Use this tool for business insights'
});

const agent = await createOpenAIFunctionsAgent({
  llm: new ChatOpenAI({ temperature: 0 }),
  tools: [suadaTool]
});

const executor = AgentExecutor.fromAgentAndTools({
  agent,
  tools: [suadaTool]
});

​

💬 Chat Interface

interface SuadaResponse {
    // Main response text
    answer: string;
    
    // Optional fields
    thoughts?: string;
    actions?: Array<{
        tool: string;
        toolInput: string;
        log: string;
    }>;
    followUpQuestion?: string;
    reasoning?: string;
    sources?: string[];
    conversationId?: string;
    timestamp: number;
}

​

👤 User Context Management

const suada = new Suada({
  apiKey: process.env.SUADA_API_KEY,
  passthroughMode: true
});

const response = await suada.chat({
  message: "What's our performance?",
  externalUserIdentifier: "user-123"
});

​

Getting Started

1. Choose Your SDK
   • Node.js: Modern JavaScript/TypeScript applications and web backends
   • Python: Data science, AI/ML, or Python web applications
2. Installation
   Copy

   # Node.js
   npm install @suada/node langchain
   
   # Python
   pip install suada langchain
   

3. Configure Environment
   Copy

   # .env file
   SUADA_API_KEY=your-api-key
   OPENAI_API_KEY=your-openai-key  # Required for LangChain integration
   

4. Initialize Client
   • Follow SDK-specific initialization
   • Configure optional features
   • Set up error handling
   • Initialize LangChain tools if needed
5. Make Your First Request
   • Send a test message
   • Handle the response
   • Implement error handling

​

Best Practices

​

Security

• Store API keys in environment variables
• Enable privacy mode for sensitive data
• Implement proper error handling

• Monitor agent performance

​

Performance

• Reuse SDK and agent instances
• Implement appropriate timeouts
• Handle rate limits gracefully
• Use async/await where available

​

Development

• Use type checking tools
• Write comprehensive tests
• Follow SDK-specific conventions
• Keep dependencies updated

​
