Vanilla JS Scraper
No credit card required
Scrape the web using familiar JavaScript methods! Crawls websites using raw HTTP requests, parses the HTML with the JSDOM package, and extracts data from the pages using Node.js code. Supports both recursive crawling and lists of URLs. This actor is a non jQuery alternative to CheerioScraper.
You can access the Vanilla JS Scraper programmatically from your own JavaScript applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in Integrations settings in Apify Console.
1import { ApifyClient } from 'apify-client';

3// Initialize the ApifyClient with your Apify API token
4// Replace the '<YOUR_API_TOKEN>' with your token
