Templates are used to convert raw synchronization data to components. Templates are defined in JSON extended with support for parameters, loops and conditions.

Handlebars syntax

StackState template files are using handlebars - a content that is placed between double curly brackets {{ some content }}. Below example shows a few handlebars used by a component template:

[{
  "_type": "Component",
  "checks": [],
  "streams": [],
  "labels": [],
  "name": "{{ name }}",
  "description": "{{ description }}",
  "type" : {{ componentTypeId }},
  "layer": {{ layerId }},
  "domain": {{ domainId }},
  "environments": [{{ environmentId }}]
}]

StackState extends on that concept and allows to include different types of content within handlebars inside .stj files:

• you can include a script (Groovy): {{ include "path/to/script.groovy" }}

• you can include an icon: {{ include "path/to/icon.png" "base64" }}

• you can include a template: {{ include "path/to/template.handlebars" }}
