<script type="text/x-red" data-help-name="template">
<p>Sets a property based on the provided template.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt>msg <span class="property-type">object</span></dt>
<dd>A msg object containing information to populate the template.</dd>
<dt class="optional">template <span class="property-type">string</span></dt>
<dd>A template to be populated from msg.payload. If not configured in the edit panel,
this can be set as a property of msg.</dd>
</dl>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>msg <span class="property-type">object</span></dt>
<dd>a msg with a property set by populating the configured template with properties from the incoming msg.</dd>
</dl>
<h3>Details</h3>
<p>By default this uses the <i><a href="http://mustache.github.io/mustache.5.html" target="_blank">mustache</a></i>
format, but this can be switched off if required.</p>
<p>For example, when a template of:
<pre>Hello {{payload.name}}. Today is {{date}}</pre>
<p>receives a message containing:
<pre>{
date: "Monday"
payload: {
name: "Fred"
}
}</pre>
<p>The resulting property will be:
<pre>Hello Fred. Today is Monday</pre>
<p>It is possible to use a property from the flow context or global context. Just use <code>{{flow.name}}</code> or
<code>{{global.name}}</code>, or for persistable store <code>store</code> use <code>{{flow[store].name}}</code> or
<code>{{global[store].name}}</code>.
<p><b>Note: </b>By default, <i>mustache</i> will escape any non-alphanumeric or HTML entities in the values it substitutes.
To prevent this, use <code>{{{triple}}}</code> braces.
