Web scraping using javascript

Question

I want to make a site (with HTML, CSS and Javascript) which will scrape data from other sites. I want to use javascript in order to accomplish that. Which is the best way to do it? I would like to avoid using Node.js or some other framework.

Answer 1

If you are getting cors error just use cors anywhere.

For dom parsing use DomParser

Example:

fetch(`https://cors-anywhere.herokuapp.com/${url}`)
.then(response => response.text())
.then(html => {
 const parser = new DOMParser()
 const dom = parser.parseFromString(htmlContent, 'text/html')
 // now you can select elements like for normal node
 dom.querySelector('div')
})

Do you have any other problems?

• gepa: Konrad thanks for the answer. So are you against of Node.js usage for this purpose?
• Konrad: I'm not against. But hosting a node.js server isn't as simple as hosting a webpage.
