title: react firebase - filtering firebase fetched items by user uid value
body: <p>In my react app i fetch a list of items from Firebase to show in a listview.</p>
  
  <pre><code>    this.fb = new Firebase(rootUrl + 'items/');
      this.bindAsObject(this.fb, 'items');
      this.fb.on('value', this.handleDataLoaded);
  </code></pre>
  
  <p>Each item has a value of a uid for a user who posted it. </p>
  
  <p>I use <code>authData.uid</code> in the app to get the logged in users uid.</p>
  
  <p>How can i go about filtering the list to show only the projects by that user?</p>
