Declarative enhancement for HTML: simple, composable, lean. TwinSpark transfers lots of the common logic from JS into a few declarative HTML attributes. This leads to good interactive sites with little JS and more manageable code.

TwinSpark is a battle-tested technology used for years on websites with 100k+ daily active users.

Explanation: click on an a element (which is enhanced with a ts-req attribute) issues an XHR request to a server. Then replaces the element with response from a server, and calls ts-req-after, which is an action.

  <div>I'm just hanging out here</div>
Update me
I'm just hanging out here
