Code Examples

Puppeteer + Chrome DevTools Protocol

Connect to Nox Core via Chrome DevTools Protocol for full browser control.

Basic Setup

// 1. Launch Nox Core with remote debugging
// Add flag: --remote-debugging-port=9222

const puppeteer = require('puppeteer-core');

const browser = await puppeteer.connect({
  browserWSEndpoint: 'ws://localhost:9222',
  defaultViewport: null
});

const page = await browser.newPage();
await page.goto('https://example.com');

Advanced Features

// Advanced profile management
const profileId = 'your-profile-id';

// Get all available targets
const targets = await browser.targets();
const pageTarget = targets.find(t => t.type() === 'page');

// Execute CDP commands
const client = await page.target().createCDPSession();

// Set custom user agent
await client.send('Network.setUserAgentOverride', {
  userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
});

// Block specific resources
await client.send('Network.setBlockedURLs', {
  urls: ['*.analytics.com', '*.tracking.js']
});

Automation Patterns

// Automation best practices
const delay = ms => new Promise(resolve => setTimeout(resolve, ms));

// Human-like typing
async function humanType(page, selector, text) {
  for (const char of text) {
    await page.type(selector, char, { delay: Math.random() * 100 + 50 });
  }
}

// Random mouse movements
async function randomMove(page) {
  await page.mouse.move(
    Math.random() * 800 + 100,
    Math.random() * 600 + 100
  );
}

// Use in your script
await randomMove(page);
await humanType(page, '#username', 'john_doe');
await delay(Math.random() * 500 + 200);
await humanType(page, '#password', 'secret123');

Best Practices

Avoid Detection

Use realistic delays between actions (200-1000ms)
Randomize mouse movements and click positions
Vary viewport sizes and user agents
Clear cookies and storage between sessions

Performance

Reuse browser instances when possible
Use headless mode for better performance
Block unnecessary resources
Implement connection pooling

Proxy Management

Rotate proxies every 10-20 requests
Match proxy location with profile timezone
Test proxy quality before use
Use residential/ISP proxies for sensitive sites

Error Handling

Implement retry logic with exponential backoff
Take screenshots on failure
Log all actions for debugging
Handle CAPTCHAs gracefully

RPA Engine Examples

Login Automation

Automate login flows with 2FA support

// Nox Core RPA - Login Flow
{
  "steps": [
    { "action": "navigate", "url": "https://example.com/login" },
    { "action": "wait", "selector": "#username", "timeout": 5000 },
    { "action": "type", "selector": "#username", "value": "{{USERNAME}}" },
    { "action": "type", "selector": "#password", "value": "{{PASSWORD}}" },
    { "action": "click", "selector": "#login-btn" },
    { "action": "wait", "selector": ".dashboard", "timeout": 10000 },
    { "action": "extract", "selector": ".user-name", "variable": "loggedUser" }
  ]
}

Data Extraction

Extract data from multiple pages

// Nox Core RPA - Data Extraction
{
  "steps": [
    { "action": "navigate", "url": "{{PRODUCT_URL}}" },
    { "action": "wait", "selector": ".product-title" },
    { "action": "extract", "selector": ".product-title", "variable": "title" },
    { "action": "extract", "selector": ".price", "variable": "price" },
    { "action": "extract", "selector": ".availability", "variable": "stock" },
    { "action": "screenshot", "name": "product_{{timestamp}}" },
    { "action": "webhook", "url": "{{API_ENDPOINT}}", "data": ["title", "price", "stock"] }
  ]
}

Form Submission

Automate complex form submissions

// Nox Core RPA - Form Submission
{
  "steps": [
    { "action": "navigate", "url": "https://example.com/form" },
    { "action": "select", "selector": "#country", "value": "{{COUNTRY}}" },
    { "action": "type", "selector": "#fullname", "value": "{{FULLNAME}}" },
    { "action": "type", "selector": "#email", "value": "{{EMAIL}}" },
    { "action": "click", "selector": "#terms-checkbox" },
    { "action": "click", "selector": "#submit-btn" },
    { "action": "wait", "selector": ".success-message", "timeout": 15000 },
    { "action": "condition", "if": ".error", "then": [{ "action": "log", "message": "Submission failed" }] }
  ]
}
