$ npm i @rpidanny/odysseys

Usage

Here's a basic example to get you started:

import { Quill } from '@rpidanny/quill'
import { Odysseus } from '@rpidanny/odysseus'

// Configuration object
const config: IConfig = {
  headless: false, // Runs browser in non-headless mode
  delay: 5000, // Wait for 5 seconds after page loads
  retry: 5, // Retry fetching content up to 5 times
  waitOnCaptcha: true, // Wait for user action when captcha is detected
}

// Optional logger
const logger = new Quill()

// Create an instance of Odysseus
const odysseus = new Odysseus(config, logger)

// Initialize odysseus
await odysseus.init()

async function fetchContent(url: string, delay: number) {
  try {
    const content = await odysseus.getContent(url, delay)
    console.log(content)
  } catch (error) {
    console.error('Failed to fetch content:', error)
  }
}

// Each fetchContent opens a new tab so can be run concurrently
await Promise.all([
  fetchContent('https://www.tiktok.com/explore', 6_000),
  fetchContent('https://www.tiktok.com/explore', 6_000),
  fetchContent('https://www.tiktok.com/explore', 6_000),
])

await odysseus.close()
