Advanced Usage

Installation & Setup

Get started with Lumen in your project quickly and easily.

NPM Installation

npm install lumen-ai

Basic Setup

import { Lumen } from 'lumen-ai';

const lumen = new Lumen({
    apiKey: 'your-api-key',
    environment: 'production'
});

Basic Configuration

Configure Lumen for your specific needs with our flexible configuration options.

Configuration Options

const config = {
    apiKey: 'your-api-key',
    environment: 'production',
    timeout: 30000,
    retries: 3,
    models: ['gpt-4', 'stable-diffusion'],
    logging: true
}

const lumen = new Lumen(config);

Authentication

Secure your Lumen API requests with proper authentication.

API Key Authentication

// Using API key in headers
const headers = {
    'Authorization': 'Bearer your-api-key',
    'Content-Type': 'application/json'
};

// Or using the SDK
const lumen = new Lumen({
    apiKey: process.env.LUMEN_API_KEY
});

First API Call

Make your first API call with Lumen.

Simple Text Analysis

// Basic sentiment analysis
const result = await lumen.analyze({
    text: "This is a sample text",
    type: "sentiment"
});

console.log(result.sentiment);

Architecture Overview

Understanding Lumen's architecture and core components.

System Components

const lumen = new Lumen({
    components: {
        nlp: true,        // Natural Language Processing
        vision: true,     // Computer Vision
        audio: true,      // Audio Processing
        inference: true   // Model Inference
    }
});

Data Flow

Lumen uses a streamlined data flow architecture:

  • Input Processing
  • Model Selection
  • Inference Engine
  • Output Formatting

Data Models

Core data structures and models used in Lumen.

Basic Data Types

interface LumenInput {
    text?: string;
    image?: Buffer;
    audio?: Buffer;
    metadata?: Record;
}

interface LumenOutput {
    result: any;
    confidence: number;
    timing: {
        start: number;
        end: number;
        duration: number;
    };
}

Model Configuration

const modelConfig = {
    type: 'classification',
    architecture: 'transformer',
    parameters: {
        layers: 12,
        heads: 8,
        hiddenSize: 768
    }
};

Error Handling

Comprehensive guide to handling errors in Lumen.

Error Types

try {
    const result = await lumen.process(input);
} catch (error) {
    if (error instanceof LumenValidationError) {
        // Handle validation errors
    } else if (error instanceof LumenAPIError) {
        // Handle API errors
    } else if (error instanceof LumenTimeoutError) {
        // Handle timeout errors
    }
}

Custom Error Handlers

lumen.onError((error, context) => {
    logger.error({
        message: error.message,
        code: error.code,
        context: context
    });
    
    // Implement fallback behavior
    return fallbackHandler(error);
});

Best Practices

Recommended patterns and practices for Lumen applications.

Performance Optimization

// Use batch processing for multiple inputs
const results = await lumen.batchProcess({
    inputs: [input1, input2, input3],
    options: {
        concurrency: 3,
        timeout: 30000
    }
});

// Implement caching for frequent requests
const cache = new LumenCache({
    ttl: 3600,
    maxSize: 1000
});

Resource Management

// Properly initialize and cleanup resources
const lumen = new Lumen();

process.on('SIGTERM', async () => {
    await lumen.shutdown();
    process.exit(0);
});

// Use connection pooling
lumen.setConnectionPool({
    min: 5,
    max: 20,
    idleTimeoutMillis: 30000
});

Rate Limit Rules

// Rate Limit Headers
X-RateLimit-Limit: 1000

// Handling Rate Limits
try {
    const response = await lumen.api.call({
        endpoint: '/analyze',
        method: 'POST',
        data: {
            text: "Sample text for analysis"
        }
    });
} catch (error) {
    if (error.code === 429) {
        const resetTime = error.headers['X-RateLimit-Reset'];
        await wait(resetTime);
        // Retry request
    }
}

API Versioning

API version management and compatibility.

Version Selection

const ridge = new Ridge({
    apiVersion: 'v1',
    compatibility: {
        minVersion: 'v1',
        maxVersion: 'v2'
    }

    }
    
    if (error instanceof ValidationError) {
        return handleValidation(error, context);
    }
    
    // Log to monitoring service
    monitoring.logError({
        error,
        context,
        severity: 'high'
    });
    
    return fallbackResponse(error);
