Turbolinks + Vue.jsPascal Laliberté
Starting small Depth
WHAT I VALUE
Turbolinks Vue.js
WHICH IS WHY I’M ATTRACTED TO THESE TWO TECHNOLOGIES
Turbolinks
A PAGE HAS A BODY
AND A HEAD
<head>
A PAGE HAS A BODY
<head>
Replaces the body
with the new content
<head>
WITH TURBOLINKS, CLICKING A LINK…

Merges the head

It keeps a Cache of snapshotsFor Back operations, etc

WHICH MAKES PAGE TRANSITIONS(AND PAGE RESTORES)
SUPER QUICK

AS AN EXAMPLE, LET’S TAKE A FORM FIELD
<div class=“purchase-form”> <input v-model=“quantity”>
AS AN EXAMPLE, LET’S TAKE A FORM FIELDAS PART OF A PURCHASE FORM…
new Vue({ el: “.purchase-form”, data: { }
quantity: null
})
<div class=“purchase-form”> <input v-model=“quantity”>
WHEN WE SETUP THE VUE INSTANCE, WE SET THE MODEL
new Vue({ el: “.purchase-form”, data: { }
quantity: 2
}
2
<div class=“purchase-form”> <input v-model=“quantity”>
})
AS THE FORM FIELD’S VALUE CHANGES, SO DOES THE VALUE IN THE MODEL
new Vue({ el: “.purchase-form”, data: { }
quantity: 23
}
23
<div class=“purchase-form”> <input v-model=“quantity”>
})
AS THE FORM FIELD’S VALUE CHANGES, SO DOES THE VALUE IN THE MODEL
AND VICE VERSA
, price: 25 }
new Vue({ el: “.purchase-form”, data: {
quantity: 23
})
23
WE CAN ADD OTHER PROPERTIES TO THE MODEL
, price: 25 }
new Vue({ el: “.purchase-form”, data: {
quantity: 23
})
23 , computed: { total () { return this.quantity * this.price } }
AND COMPUTED PROPERTIES TOO, WHICH UPDATE ON THE FLY
, price: 25 }
new Vue({ el: “.purchase-form”, data: {
quantity: 23
})
23
methods events components
, computed: { total () { return this.quantity * this.price } }
YOU CAN ALSO DEFINE
<map-popover :lat=“lat” :long=“long” :zoom=“zoom” ></map-popover>
DEFINING SUB-COMPONENTS MAKES VUE SCALABLE

YOU CAN GO ALL OUT AND BUILD A SPA…
Approachable
SmallFast
DelightfulScalable
BUT VUE’S BEST QUALITIES ARE THAT IT IS
Now available: Vue.js 2.0
IF YOU WANT
mostly server-generated content
in places: more front-end reactivity
Turbolinks + Vuejs
mostly jQuery / Vanilla js, Unobtrusive JS
<head>
Replaces the body

<head>
WITH TURBOLINKS, CLICKING A LINK…
Merges the head
It keeps a Cache of snapshotsFor Back operations, etc
THE PROBLEM MERGING THEM TOGETHER IS THE BODY REPLACEMENT
CAUSES VUE INSTANCES TO LOSE REACTIVITY ON RESTORES
Turbolinks + Vuejs
new Vue({ el: “.purchase-form”, data: { }
quantity: 23
}
23
REACTIVITY = DOM EVENTS, OBSERVERS
DESTROYED WHEN CLONING THE BODY FOR THE RESTORE CACHE
FOR THE SOLUTION LET’S LOOK AT THE TIMELINE OF EVENTS
