Quick Start

Basic HTTP Requests

Experience the elegance of Uniqhtt's intuitive API designed for both simplicity and power:

import uniqhtt from 'uniqhtt';

// Effortless GET request with automatic response parsing
const response = await uniqhtt.get<User[]>('https://api.example.com/users');
console.log(response.data); // Fully typed response data

// Streamlined JSON POST with intelligent content-type handling
const user = await uniqhtt.postJson<User>('https://api.example.com/users', {
  name: 'John Doe',
  email: 'john@example.com',
  preferences: { theme: 'dark', notifications: true }
});

// Form-encoded POST with automatic serialization
const loginResult = await uniqhtt.postForm<AuthResponse>('https://api.example.com/login', {
  username: 'john',
  password: 'secret',
  rememberMe: true
});

console.log(`Welcome ${loginResult.data.user.name}!`);

File Downloads

Uniqhtt's file download capabilities provide enterprise-grade performance with comprehensive progress tracking and metadata extraction:

import { DownloadResponse } from 'uniqhtt';

// Direct-to-disk streaming download with automatic directory creation
const downloadResult: DownloadResponse<null> = await uniqhtt.download(
  'https://example.com/large-dataset.zip',
  './downloads/dataset.zip'
);

const downloadResult2: DownloadResponse<null> = await uniqhtt.post('https://example.com/large-dataset.zip', {},
        {saveTo: './downloads/dataset.zip'}
);

console.log(`✅ Download completed successfully:`);
console.log(`   File: ${downloadResult.fileName}`);
console.log(`   Size: ${downloadResult.size}`);
console.log(`   Speed: ${downloadResult.downloadSpeed}`);
console.log(`   Duration: ${downloadResult.totalTime}`);

// Alternative syntax for file downloads with full response access
const fileResponse = await uniqhtt.get<null>('https://example.com/report.pdf', {
  saveTo: './reports/monthly-report.pdf'
});

Core Features

Cookie Management

Uniqhtt's cookie management system represents a sophisticated approach to session handling, providing seamless persistence and intelligent domain management across complex web interactions:

import { Uniqhtt, Cookie, SerializedCookie } from 'uniqhtt';

const client = new Uniqhtt();

// Programmatic cookie creation with comprehensive attribute support
const sessionCookie = new Cookie({
  key: 'session_token',
  value: 'eyJhbGciOiJIUzI1NiIs...',
  domain: '.example.com',
  path: '/',
  secure: true,
  httpOnly: true,
  sameSite: 'strict',
  expires: new Date(Date.now() + 24 * 60 * 60 * 1000) // 24 hours
});

client.setCookies([sessionCookie]);

// Bulk cookie import from various formats
const netscapeCookies = `
# Netscape HTTP Cookie File
.example.com	TRUE	/	TRUE	${Date.now() + 86400000}	auth_token	abc123
.example.com	TRUE	/api	FALSE	0	api_key	xyz789
`;
client.setCookies(netscapeCookies);

// Automatic cookie persistence across requests
const dashboardData = await client.get<DashboardData>('https://example.com/dashboard');
const apiResponse = await client.post<ApiResult>('https://example.com/api/data', payload);

// Advanced cookie introspection and management
const currentCookies = client.getCookies();
console.log('Cookie String:', currentCookies.string);        // HTTP Cookie header format
console.log('Netscape Format:', currentCookies.netscape);    // For browser import/export
console.log('Serialized:', currentCookies.serialized);      // For JSON storage

Proxy Configuration

Uniqhtt's proxy infrastructure supports enterprise networking environments with comprehensive protocol support and intelligent failover mechanisms:

import { Uniqhtt, IProxy } from 'uniqhtt';

// Advanced SOCKS5 proxy configuration with authentication
const socksProxy: IProxy = {
  protocol: 'socks5',
  host: '127.0.0.1',
  port: 9050,
  username: 'proxy_user',
  password: 'secure_password',
  keepAlive: true,
  timeout: 30000,
  maxSockets: 10
};

const client = new Uniqhtt({ proxy: socksProxy });

// Corporate HTTP proxy with custom configuration
const corporateProxy: IProxy = {
  protocol: 'https',
  host: 'proxy.corporate.com',
  port: 8080,
  username: 'employee_id',
  password: 'access_token',
  rejectUnauthorized: false, // For internal certificates
  keepAliveMsecs: 60000
};

// All requests automatically route through configured proxy
const externalData = await client.get<ExternalApiResponse>('https://api.external.com/data');
console.log('Request routed through proxy:', externalData.status);

Request Queue & Rate Limiting

The integrated queue management system provides sophisticated traffic control, ensuring respectful interaction with target servers while maximizing throughput efficiency:

import { Uniqhtt, queueOptions } from 'uniqhtt';

// Enterprise-grade queue configuration for high-throughput scenarios
const queueConfig: queueOptions = {
  concurrency: 5,           // Maximum simultaneous requests
  interval: 1000,           // Time window in milliseconds  
  intervalCap: 2,           // Requests allowed per interval
  timeout: 30000,           // Individual request timeout
  throwOnTimeout: true,     // Fail fast on queue timeout
  autoStart: true           // Begin processing immediately
};

const client = new Uniqhtt({
  queueOptions: {
    enable: true,
    options: queueConfig
  }
});

// Bulk operations automatically respect queue constraints
const endpoints: string[] = [
  'https://api.example.com/users',
  'https://api.example.com/products', 
  'https://api.example.com/orders',
  // ... hundreds more URLs
];

const results = await Promise.all(
  endpoints.map((url, index) => 
    client.get<ApiResponse>(`${url}?page=${index}`)
  )
); // Automatically throttled to queue specifications

console.log(`Processed ${results.length} requests with optimal rate limiting`);

Retry Logic

Uniqhtt's retry framework implements intelligent failure recovery with adaptive backoff strategies and conditional retry logic:

import { UniqhttResponse, UniqhttError } from 'uniqhtt';

// Sophisticated retry configuration with exponential backoff
const resilientResponse = await uniqhtt.get<CriticalData>('https://unreliable-api.com/critical-data', {
  retry: {
    maxRetries: 5,
    retryDelay: 1000,        // Initial delay: 1 second
    incrementDelay: true     // Exponential backoff: 1s, 2s, 4s, 8s, 16s
  },
  timeout: 10000
});

console.log('Data retrieved successfully:', resilientResponse.data);

Multipart Form Data

Advanced multipart handling with comprehensive file upload support and intelligent content-type detection:

import { FormData, UniqhttResponse } from 'uniqhtt';
import { readFileSync } from 'fs';

// Comprehensive multipart form construction
const formData = new FormData();
formData.append('document', readFileSync('./contract.pdf'), {
  filename: 'contract-v2.pdf',
  contentType: 'application/pdf'
});
formData.append('metadata', JSON.stringify({
  title: 'Service Agreement',
  version: '2.1',
  confidential: true
}), { contentType: 'application/json' });
formData.append('signature', 'John Doe');
formData.append('timestamp', new Date().toISOString());

// Streamlined multipart upload with progress tracking
const uploadResult = await uniqhtt.postMultipart<UploadResponse>(
  'https://api.example.com/documents/upload',
  formData,
  {
    timeout: 120000, // Extended timeout for large files
    headers: {
      'X-Upload-Session': 'session_12345',
      'X-Client-Version': '1.0.0'
    }
  }
);

console.log(`Document uploaded: ${uploadResult.data.documentId}`);

Web Crawler

Uniqhtt's integrated crawler represents a production-ready web automation platform, featuring intelligent DOM manipulation, advanced caching strategies, and event-driven data extraction architecture.

Basic Crawling

The crawler provides an elegant, declarative approach to web data extraction with automatic queue management and intelligent content processing:

import uniqhtt from 'uniqhtt';

// Configure enterprise crawler with comprehensive options
const crawler = uniqhtt.crawler({
  crawlerOptions: {
    queueOptions: { concurrency: 3 },
    baseUrl: 'https://ecommerce.example.com',
    enableCache: true,
    cacheTTL: 1000 * 60 * 60, // 1 hour cache
    timeout: 15000,
    maxRetryAttempts: 3,
    retryDelay: 2000,
    headers: {
      'User-Agent': 'Uniqhtt-Crawler/1.0 (+https://company.com/bot)',
      'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'
    }
  }
});

// Event-driven data extraction with intelligent selectors
crawler
  .onSelection<HTMLAnchorElement>('a[href*="/products/"]', (productLink) => {
    const productUrl = productLink.getAttribute('href');
    if (productUrl) {
      crawler.visit(productUrl); // Queues for processing
    }
  })
  .onSelection<HTMLElement>('.product-title', (titleElement) => {
    console.log('Product Found:', titleElement.textContent?.trim());
  })
  .onSelection<HTMLElement>('.price', (priceElement) => {
    const price = priceElement.textContent?.match(/\$(\d+\.?\d*)/)?.[1];
    if (price) {
      console.log('Price:', parseFloat(price));
    }
  })
  .onJsonData<ProductData>((apiData) => {
    // Handle JSON API responses within pages
    console.log('API Data:', apiData.products.length, 'products loaded');
  });

// Initiate crawling process (synchronous queue addition)
crawler.visit('/catalog');
crawler.visit('/featured-products');
crawler.visit('/new-arrivals');

// Wait for all queued operations to complete (asynchronous)
await crawler.waitForAll(); // Wait for all queued requests
console.log('✅ Crawling completed successfully');

Dual HTTP Client Architecture

Advanced crawler configuration supporting differentiated handling of internal and external requests:

// Primary crawler for main domain with proxy routing
const advancedCrawler = uniqhtt.crawler({
  crawlerOptions: {
    queueOptions: { concurrency: 4 },
    baseUrl: 'https://main-site.com',
    socksProxies: [
      {
        protocol: 'socks5',
        host: '127.0.0.1',
        port: 9050
      }
    ],
    retryOnProxyError: true,
    enableCache: true,
    debug: true
  },
  
  // Secondary client for external domain handling
  crawler2Options: {
    timeout: 8000,
    useProxy: false,           // Bypass proxy for external requests
    concurrency: 2,            // Lower concurrency for external sites
    respectQueueOption: true,  // Honor queue settings
    maxRetryAttempts: 1        // Reduced retries for external resources
  }
});

// Intelligent request routing based on domain
advancedCrawler
  .onSelection<HTMLAnchorElement>('a[href]', (link) => {
    const href = link.getAttribute('href');
    if (!href) return;
    
    const url = new URL(href, 'https://main-site.com');
    
    if (url.hostname === 'main-site.com') {
      // Internal links use primary client (with proxy)
      crawler.visit(url.pathname);
    } else {
      // External links use secondary client (direct connection)
      crawler.visit2(url.href);
    }
  });

crawler.visit('/');
await crawler.waitForAll(); // Wait for all queued requests

Event-Driven Data Extraction

Comprehensive event system for sophisticated data extraction and processing workflows:

interface ProductData {
  id: string;
  name: string;
  price: number;
  availability: boolean;
}

const dataCrawler = uniqhtt.crawler({
  crawlerOptions: {
    queueOptions: { concurrency: 5 },
    baseUrl: 'https://api-driven-site.com',
    enableCache: true
  }
});

// Multiple event handlers for comprehensive data capture
dataCrawler
  .onDocument((document) => {
    // Full document processing
    const title = document.querySelector('title')?.textContent;
    console.log('Page Title:', title);
  })
  .onResponse<string>((response) => {
    // Access to full HTTP response
    console.log(`Response: ${response.status} - ${response.finalUrl}`);
    console.log(`Content-Type: ${response.contentType}`);
  })
  .onJsonData<ProductData[]>((jsonData) => {
    // Automatic JSON parsing and type safety
    jsonData.forEach(product => {
      console.log(`Product: ${product.name} - $${product.price}`);
    });
  })
  .onRawData((buffer) => {
    // Raw response data access for custom processing
    console.log(`Received ${buffer.length} bytes`);
  })
  .onAnchor((anchor) => {
    // Specialized anchor element handling
    const href = anchor.href;
    const text = anchor.textContent;
    console.log(`Link: ${text} -> ${href}`);
  })
  .onAttribute('data-product-id', (productId) => {
    // Extract specific attributes across all elements
    console.log('Product ID found:', productId);
  });

dataCrawler.visit('/products');
await dataCrawler.waitForAll(); // Wait for all queued requests

Configuration

Global Configuration

Establish consistent behavior across all requests with comprehensive global settings:

import { Uniqhtt } from 'uniqhtt';

const client = new Uniqhtt({
  baseURL: 'https://api.enterprise.com/v2',
  timeout: 30000,
  
  headers: {
    'User-Agent': 'Enterprise-App/2.1.0',
    'Authorization': 'Bearer eyJhbGciOiJIUzI1NiIs...',
    'X-API-Version': '2.1',
    'X-Client-ID': 'app_12345'
  },
  
  // Browser behavior simulation
  mimicBrowser: true,
  
  // Global retry policy
  retry: {
    maxRetries: 3,
    retryDelay: 1500,
    incrementDelay: true
  },
  
  // Advanced networking options
  rejectUnauthorized: true,
  useSecureContext: true,
  
  // Cookie management
  enableCookieJar: true,
  
  // Queue configuration for all requests
  queueOptions: {
    enable: true,
    options: {
      concurrency: 10,
      interval: 500,
      intervalCap: 5
    }
  }
});

Per-Request Configuration

Fine-tune individual requests with granular control over behavior and processing:

import { UniqhttResponse } from 'uniqhtt';

const customResponse = await uniqhtt.get<ApiData>('https://api.example.com/sensitive-data', {
  headers: { 
    'X-Request-ID': crypto.randomUUID(),
    'X-Priority': 'high'
  },
  
  timeout: 5000,
  maxRedirects: 3,
  
  // Custom response validation
  validateStatus: (status: number): boolean => {
    return status >= 200 && status < 300;
  },
  
  // Redirect handling with custom logic
  onRedirect: ({ url, status, sameDomain, method }) => {
    console.log(`Redirecting to: ${url.href} (${status})`);
    
    if (!sameDomain) {
      console.warn('Cross-domain redirect detected');
      return { 
        redirect: false,
        message: 'Cross-domain redirects not allowed'
      };
    }
    
    return { 
      redirect: true,
      method: status === 303 ? 'GET' : method,
      withoutBody: status === 303
    };
  },
  
  // Custom error recovery
  retry: {
    maxRetries: 2,
    retryDelay: 1000,
    incrementDelay: false
  }
});

TypeScript Support

Uniqhtt's TypeScript integration provides comprehensive type safety with intelligent inference and generic support:

import uniqhtt, { 
  UniqhttResponse, 
  UniqhttError, 
  HttpConfig,
  DownloadResponse 
} from 'uniqhtt';

// Define API response interfaces
interface User {
  id: number;
  name: string;
  email: string;
  profile: {
    avatar_url: string;
    preferences: Record<string, any>;
  };
}

interface ApiError {
  error: string;
  code: number;
  details?: string[];
}

// Fully typed request with comprehensive error handling
async function fetchUserData(userId: number): Promise<User> {
  try {
    const response: UniqhttResponse<User> = await uniqhtt.get<User>(
      `https://api.example.com/users/${userId}`,
      {
        headers: {
          'Accept': 'application/json',
          'X-Request-ID': crypto.randomUUID()
        },
        timeout: 10000
      } as HttpConfig
    );
    
    // Full type safety on response properties
    console.log(`User: ${response.data.name}`);
    console.log(`Status: ${response.status}`);
    console.log(`Content-Type: ${response.contentType}`);
    console.log(`Final URL: ${response.finalUrl}`);
    
    return response.data;
    
  } catch (error) {
    if (error instanceof UniqhttError) {
      // Typed error handling
      const errorData = error.response.data as ApiError;
      console.error(`API Error: ${errorData.error} (${errorData.code})`);
      console.error(`Status: ${error.response.status}`);
      console.error(`URL: ${error.response.finalUrl}`);
    }
    throw error;
  }
}

// Generic utility for typed API calls
async function apiCall<T, E = ApiError>(
  endpoint: string,
  options?: HttpConfig
): Promise<T> {
  const response = await uniqhtt.get<T>(endpoint, options);
  return response.data;
}

// Usage with full type inference
const users = await apiCall<User[]>('/users');
const settings = await apiCall<AppSettings>('/settings');

Environment Detection

Uniqhtt automatically adapts to different runtime environments while maintaining consistent API behavior:

// Node.js environment - Full feature set including file system operations
import uniqhtt from 'uniqhtt/nodejs';
import { UniqhttNode } from 'uniqhtt';

const nodeClient = new UniqhttNode({
  useCurl: true,  // Enable cURL backend for advanced features
  httpAgent: customHttpAgent,
  httpsAgent: customHttpsAgent
});

// Edge environment - Optimized for serverless and edge computing
import uniqhtt from 'uniqhtt/edge';
import { UniqhttEdge } from 'uniqhtt';

const edgeClient = new UniqhttEdge({
  timeout: 5000,  // Shorter timeouts for edge environments
  maxRedirects: 3
});

// Automatic detection (recommended) - Chooses optimal implementation
import uniqhtt, { Uniqhtt } from 'uniqhtt';

// Runtime detection happens automatically
const response = await uniqhtt.get('https://api.example.com/data');

Error Handling

Comprehensive error management with detailed context and intelligent recovery strategies:

import { UniqhttError, UniqhttResponse } from 'uniqhtt';

async function robustApiCall<T>(url: string): Promise<T> {
  try {
    const response = await uniqhtt.get<T>(url, {
      retry: {
        maxRetries: 3,
        retryDelay: 1000,
        incrementDelay: true
      },
      timeout: 15000
    });
    
    return response.data;
    
  } catch (error) {
    if (error instanceof UniqhttError) {
      // Comprehensive error context
      const errorInfo = {
        message: error.message,
        code: error.code,
        status: error.response.status,
        statusText: error.response.statusText,
        url: error.response.finalUrl,
        headers: error.response.headers,
        data: error.response.data
      };
      
      console.error('Request failed:', errorInfo);
      
      // Conditional error handling based on status
      switch (error.response.status) {
        case 401:
          console.error('Authentication required');
          // Trigger re-authentication flow
          break;
        case 403:
          console.error('Access forbidden');
          // Handle authorization failure
          break;
        case 429:
          console.error('Rate limit exceeded');
          // Implement backoff strategy
          break;
        case 500:
        case 502:
        case 503:
        case 504:
          console.error('Server error - retry may succeed');
          // Server errors might be temporary
          break;
        default:
          console.error('Unexpected error');
      }
    } else {
      // Handle non-Uniqhtt errors
      console.error('Unknown error:', error);
    }
    
    throw error;
  }
}
