Slow performance rendering in client templating engine (Rivets.js)

Question

I'm rendering an array of of about 1000 objects. The html bindings are very heavy (see below). It's taking about 5 seconds to rivets.bind().

Any suggestions on improving performance? I don't think I can afford to bind in chunks as I'm using a pagination/sorting library in conjuction that needs the entire array in order to sort/paginate.

Here is my HTML for each object (tracks):

<div rv-each-track="tracks" class="track-row row has-hover" rv-download-url="track.direct_path.download_path" rv-api-key="track.track.apikey" rv-media-url="track.direct_path.audio" rv-track-title="track.track.name" rv-wave-data="track.direct_path.wave_default" rv-wave-progress-data="track.direct_path.wave_progress">
<div class="mobile-margin">

        <div class="hover-title"><a href="#" class="track-link">{track.track.name}</a><span rv-class="track.track.staff_pick | staffPickClass" data-toggle="tooltip" data-original-title="Staff Pick"></span></div>

Answer 1

I've come to the the conclusion that yes, there are minor performance improvements that I could potentially implement for binding 1000+ (large html) objects to the DOM using Rivets. However, the root issue is the fact that I'm trying to bind 1000+ rivets into the DOM at once and that is going to be inherently slow using any technique (I've tested with React, jQuery, Rivets, etc...).

The solution to this problem is to simply find another way. I've chosen to pre-render the html on the server and serve it up through an API response. This cut the page load time down from ~5s to ~1s.
