Tempo is a JSON rendering engine with a light footprint (4kb) for easily designing data templates using pure HTML.

The engine enables us to separate HTML – JavaScript completely and also simplifies dealing with AJAX content.

It also has support for nested and conditional templates (boolean and value-based).

Normally, there is always a chance that data templates being visible before rendered by the browser. To prevent this, you can hide them via CSS and Tempo will smartly remove any inline rules after it is completely rendered.

Tempo doesn't depend on any other library and degrades gracefully if JavaScript is not enabled.

There is a simple Twitter-related demo that shows how powerful it can be.
