Handlebars syntax

Here's a short guide to Handlebars syntax. For more information, consult the official Handlebars documentation.


You refer to variables like this:

{{ variable_name }}

If the variable is an object with properties of its own, you can refer to them like so:

{{ person.firstName }}

This is how you refer to a specific index of an array:

{{ people.[0] }}


You can use Handlebars comments in your files. Commented out sections won't show up in the final rendered output.

{{! This comment will not show up in the output}}

If the content you want to comment out contains }} or other Handlebars tokens, you need to use different comment style:

{{!-- This comment may contain mustaches like }} --}}


Here's an example of if-condition:

{{#if some_variable}}
this will be included in the output

Iterating over collections

This is how you iterate over a collection of items:

{{#each securityGroupIds}}
- {{this}}

Escaping expressions

If you don't want to process a Handlebars expressio, you can escape it by prefixing it with an escape character \ like so:

\{{my expression to escape}}
