Handlebars syntax#

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

Variables#

You refer to variables like this:

1{{ variable_name }}

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

1{{ person.firstName }}

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

1{{ people.[0] }}

Comments#

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

1{{! 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:

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

If-conditions#

Here's an example of if-condition:

1{{#if some_variable}}
2  this will be included in the output
3{{/if}}

Iterating over collections#

This is how you iterate over a collection of items:

1{{#each securityGroupIds}}
2  - {{this}}
3{{/each}}

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:

1\{{my expression to escape}}
