title: How to get temperature value on javascript (serverside)?
body: <p>I was looking to use a weather API (like yahoo's) and make my javascript code able to return the temperature given a city.
  My app runs on rivescript (built on javascript and node).</p>
  
  <p>Researching I only found ways to do it locally on json, or by using html and css as well, but I just want a simple javascript code that returns a value with the temperature.</p>
  
  <p>Thanks</p>
