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.

The code examples below show how to run the Actor and get its results. To run the code, you need to have an Apify account. Replace <YOUR_API_TOKEN> in the code with your API token, which you can find under Settings > Integrations in Apify Console. Learn mode
