How to correctly pass a parameter from Vue to Pug
I did something like this:

<template lang="pug">

    - var newDesign = isNewDesign; // isNewDesign - это параметр из data

        p test: #{newDesign} // тут ничего не выводит, получается "test: "


</template>

Is it possible to pass this parameter somehow or not?

Answer 1

And what's the difference whether you have pug or not pug? Everything is as usual:
p test: {{ isNewDesign }}
