Handlebars Helpers

If

Conditionally renders content based on truthy values during Handlebars substitution. Useful for optional message sections, prompts, payload fields, and template output.

Important
This helper can only be used to evaluate the truthiness of a variable, this means you cannot use any comparison operators like ==, ===, !=, !==, >, <, >=, <=.
You also can't do any arithmetic operations or any other expressions.

Use comparison helpers such as eq when you need to compare values inside an if, or if-eq when you want the comparison and conditional block combined.

# Example: Basic IF Conditional Rendering

This example shows how to conditionally render a block of text based on the value of a variable.

Example definition:

        {{#if stub.data.is_admin}}
Hello Admin
{{/if}}"


      

If the is_admin variable is true, the output will be:

        Hello Admin

      

If the is_admin variable is false, the output will be empty.

# Example: IF-ELSE Conditional Rendering

This example shows how to conditionally render a block of text based on the value of a variable.

Example definition:

        {{#if stub.data.is_admin}}
Hello Admin
{{else}}
Hello User
{{/if}}"


      

If the is_admin variable is true, the output will be:

        Hello Admin

      

If the is_admin variable is false, the output will be:

        Hello User

      

# Example ERROR

!This cannot be done!

ERROR

        {{#if stub.data.name == "John"}}
Hello Admin
{{else}}
Hello User
{{/if}}"


      

This will throw an error on the _create action when a new stub is created.
