I'm using assemble with grunt to build handlebars templates, but I've got some areas that I don't want to be compiled, so that they can be rendered afterwards in the browser.
Are there any special tags/helpers that can do that ?
You can escape the handlebars so they're excluded during the assemble build, then use them in the frontend...
{{! rendered by assemble }}
<h1>{{foo}}</h1>
\{{! rendered on the browser }}
<h2>\{{bar}}</h2>
