title: Iron-signal alternate in Polymer 2?
body: <p>I have been using iron-signals almost everywhere in my application. </p>
  
  <p>Now I was upgrading my polymer 1 application to polymer 2 and I found that <code>&lt;iron-signals&gt;</code> is not used anymore. </p>
  
  <p>What is the alternate path to achieve the same. I basically want to pass data between different pages in my web app. </p>
