How To Avoid Meteor Helpers Run Multiple Times
In my template I have this HTML:
Solution 1:
The card helper is executed several times since card is present in evaluated template code more than once.
A pattern to avoid duplicate calls in scenarios like the one you're facing is to use #with:
{{#with card}}
<input id="name" type="text" value="{{name}}">
<input id="prefix" type="text" value="{{prefix}}">
<input id="phone" type="tel" value="{{phone}}">
{{/with}}
This will call card once and then run the nested code in the context of its result.
