HTML and the Web

Downloading a web page

Ruby makes downloading a web page straightforward with libraries like net/http and gems like open-uri.

To parse HTML in Ruby, install the ‘Nokogiri’ gem with gem install nokogiri.

Ruby makes it pretty easy to send HTTP requests.

To send an HTTP request with basic authentication, you’ll typically use the Net::HTTP module in Ruby.
