Handlebars: disable some content based on the url - node.js

Question

I have a basical layout with a sidebar. I want to hide the sidebar when I am on /users/profile. How can I do it using the if helper? Is there a way to get the current file name?
Here is the code:
<div class="wrapper">
{{#if user}}
<nav id="sidebar">
<div class="sidebar-header">
<h3>Options</h3>
</div>
<ul class="list-unstyled components">
<li class="active">
<h1>
Home
</h1>
</li>
<li>
<h1>
Chat
</h1>
</li>
<li>
<h1>
About us
</h1>
</li>
</ul>
</nav>
{{else}}
{{/if}}
With the current code if a user is logged in the sidebar is showed , otherwise it is hidden. I want the same behaviour also if I am on users/profile.

Your routing is handled by Node.js. Somewhere in your Node.js you probably have instructions on what to do when the user opens /users/chatlist or /users/search, e.g. you select which template to render. Once you know the request is for route /users/profile, you use a JSON payload for your handlebars to properly render the page. You can customize that payload as you wish, including adding some helper fields. For example it may look like:
{
user: { ... },
sidebar: {
visible: false
}
}
Then inside your template, you may use it for a conditional check, like:
{{#if sidebar.visible}}
<nav id="sidebar">
...
</nav>
{{/if}}
