node.js and Handlebars: HTML compiled is escaped

问题

Im using handlebars in a node aplication, and I have trouble.

This is the template index.html

{{CONTENT}}

This is the code

var fs = require("fs");
var handlebars = require("handlebars");

var data = {
    CONTENT: "<b>Hello world!</b>"
};

var templateFile = fs.readFileSync('./index.html', 'utf8');
var template = handlebars.compile( templateFile );
var html = template(data);

The problem is that the tags <B> are escaped to <B>

How can I avoid this?

From handlebarsjs.com :

Handlebars HTML-escapes values returned by a {{expression}}. If you don't want Handlebars to escape a value, use the "triple-stash".

<div class="entry">
  <h1>{{title}}</h1>
  <div class="body">
    {{{body}}}
  </div>
</div>

with this context:

{
  title: "All about <p> Tags",
  body: "<p>This is a post about &lt;p&gt; tags</p>"
}

results in:

<div class="entry">
  <h1>All About &lt;p&gt; Tags</h1>
  <div class="body">
    <p>This is a post about &lt;p&gt; tags</p>
  </div>
</div>

However from my point of view it may defeat the purpose of having a template separated than you're js file.

If you use precompile then use noEscape option:

handlebars.precompile(content, {noEscape: true})

You'd want to use the 'triple stash' in your template:

{{{CONTENT}}}
