Bars is a lightweight high performance HTML aware templating engine. Bars emits DOM rather than DOM-strings, this means the DOM state is preserved even if data updates happen. Bars can also emit DOM-strings for backend templating if desired. This way one can use Bars for both static content generation and dynamic web application views.
