After attempting to dynamically toggle the className based on computed property and encountering issues in Pug, I found that manually setting 'true' to a className was the solution. Even after trying to reassign the computed property to a Pug variable, it still did not work.
In contrast, using pure HTML allowed for classes to dynamically toggle correctly.
Pug:
main#app.container
- var isPinkDefinitely = isPink ? 'pink' : 'gray';
div.section(
v-bind:class=[
'custom-section',
{
'custom-section--pink': isPink
}
]
v-bind:style=[
{
'background-color': isPinkDefinitely
}
]
) {{ isPink }}
form(@submit.prevent="addItem")
label.label Add another
div.field.has-addons
div.control
input.input(required, autofocus, v-model="newItem", placeholder="Remake this in React")
button(type="submit").button.is-info
i.fa.fa-plus
span Add
transition(name="slide")
div(v-show="items.length > 0")
hr
ul
transition-group(name="slide")
li(v-for="(item, index) in items", :key="item.id")
button(@click="removeItem(index)").button.is-danger
i.fa.fa-trash
span(v-text="item.desc")
hr
span(v-text="'Total: ' + items.length")
JS:
new Vue({
el: '#app',
data: {
items: [
{id: 1, desc: "Lorem"},
{id: 2, desc: "Ipsum"},
{id: 3, desc: "Dolor"},
],
newItem: '',
},
computed: {
isPink() {
return true;
}
},
methods: {
addItem () {
const id = this.items.length + 1
this.items.push({id, desc: this.newItem})
this.newItem = ''
},
removeItem (index) {
this.items.splice(index, 1)
},
},
})

UPD: SO the basically solution was to just write all classes in one line inside just an object. see solution of @aykut
