====== Native Engine - Json Template ======

===== Template =====
A ''Json'' template is a [[docs:templating:native|native template]]:
  * that is a valid [[docs:resource:json|Json]] text document
  * that may contain variables in the form ''${name}'' in its properties key and/or value.
  * that will respect the tree structure (There is no need to add extra processing logic such as loop)
  * that produces a [[docs:resource:json|json data resource]].




===== Howto =====
[[howto:templating:create_json_from_tabular_data]]


===== Example:  catalog of item =====

The variable name should match the name of a column of the [[docs:flow:source|source]].

<code javascript>
{
  "${group}": {
    "${item_code}": {
      "price": "${price}",
      "description": "${description}"
    }
  }
}
</code>
where:
  * ''group'', ''item_code'', ''price'' and ''description'' (from ''${group}}'', ''${item_code}'', ''${price}'' and ''${description}'') are the column names of the [[docs:flow:source|source]].
