This is a fantastic video from Smitha Milli, which will help you get started with web scraping using Node.js.

Also, there are a few interesting projects that might need to check out in the future.

1. Nokogiri in Ruby

2. Request and Cheerio in Node.js

3. pjscrape Javascript (using PhantomJS and jQuery)

I also modified her code a little bit and pushed my own code to my github account. It will save the raw html along with other interesting attributes to a plain file in json format. And people can extract the part they want in the future.
