title: How to access url params in sapper outside of preload function?
body: <p>In Sapper, AFAIK from documentation. The only way to access URL params are through <code>preload()</code> function, from which params are available inside <code>params</code> object.</p>
  
  <p>The thing is that I want to access these params ouside of <code>preload()</code> function. From an eagle eye view of documentation. I don't / can't see the solution to my problem / requirement.</p>
  
  <p>I have tried setting a property for url param inside <code>data()</code>. But it seems <code>preload()</code> has no access to <code>data</code> whether getting wise or setting wise. <em>It is not meant for those things.</em></p>
