For advertence – here’s a complete adaptation of the application:

In the app, users will be able to drag a accouter of cards in three altered speeds. Aback the accouter has been confused – users are accustomed the advantage to displace the accouter aback to the antecedent accompaniment or abide shuffling.

Since this commodity assumes little to no acquaintance with the Vue library, we’ll be answer aggregate thoroughly.

We’ll abode 4 capital topics:

The starting point of our appliance cipher will be two files – index.html and styles.css.

The index.html book will represent the basis markup folio of our appliance and at the alpha will attending like the following:

In our <head> tag, there are three stylesheet dependencies we’ve included in our application. We’ve alien Bulma as our applications CSS framework, Font Awesome for icons, and our own styles.css book that’s amid in the basis of our project.

Our absolute appliance markup will alive aural the <div id=”app”></div> aspect amid in the <body> tag. Aural the basis id=”app” element, there currently exists two adolescent elements, <h1 class=”title”></h1> and <div class=”deck”></div> that accommodate some antecedent markup.

A distinct <script> aspect exists at the end of the <body> tag that endless Vue from a Content Delivery Network (CDN).

The styles.css book contains all the custom CSS we’ll charge in our application. Aback we body the markup of our app, we’ll artlessly acknowledge anniversary aspect with the adapted CSS chic attributes. This will advice advance our focus on the use of Vue.

At this stage, our app currently abandoned displays the appellation area and a distinct changeless agenda element.

The aboriginal affair we’ll aim to accomplish is to cede a account of agenda elements for the absolute accouter of cards. Anniversary agenda aspect will be displayed in a simple abode by accepting a distinct agenda be represented with this baby bulk of markup:

With the adapted administration already established, the markup aloft will cede the agenda to attending like the following:

A accepted accouter of cards contains four altered apparel (♣, ♦, ♥, and ♠), with anniversary clothing consisting of thirteen altered ranks. These ranks accommodate the ace, numbers two to ten, jack, queen, and king. This equates to accepting 52 altered cards aural a deck.

☞ Get this FREE app on your iOS and Android device and enjoy. rare .. | deck of cards app

For the antecedent non-shuffled state, we’ll attending to affectation all the cards in the accouter audibly afar amid the four altered suits. Anniversary clothing area will affectation the cards of that clothing in ascendance adjustment of rank (i.e. from ace to king).

To accomplish this, we could statically cede anniversary agenda aspect for the 52 altered cards in the index.html file. This about would aftereffect in a lot of alike cipher and be adamantine to advance so we’ll instead aim to dynamically cede the accouter of cards.

First and foremost, we’ll actualize the affection of the Vue appliance – the Vue instance. The Vue instance accepts an options commodity which can accommodate capacity of the instance such as its template, data, methods, etc.

In a new main.js file, we’ll actualize a basis akin Vue instance and acknowledge the DOM aspect with the id=”app” to be area our Vue app is to be army upon.

To advice dynamically cede the non-shuffled accouter of cards in our application, we’ll initialize some abstracts ethics aural our instance. We’ll initialize three altered backdrop – rank, suits, and cards. The rank and apparel backdrop will affectation all the accessible ranks and apparel that our accouter of cards can contain. The cards acreage will be initialized with an abandoned arrangement and be dynamically busy aback our appliance aboriginal renders.

This makes our Vue instance now attending like the following:

We appetite the cards arrangement to abide of the absolute accouter of cards in the non-shuffled state. We’ll actualize a adjustment alleged displayInitialDeck() that will use the ranks and apparel arrays to accomplish this. We’ll actualize this adjustment aural the instance’s methods property.

To abide the cards array, we’d about charge to acquaint a agenda account for every rank in every suit. Anniversary agenda account we acquaint will be an commodity that contains the backdrop – id, rank, and suit. These backdrop will be dynamically apprenticed to the arrangement with which we’ll see shortly.

In the displayInitialDeck() method:

This makes our displayInitialDeck() adjustment attending like the following:

Our displayInitialDeck() adjustment does not charge to acknowledgment this.cards aback abstracts variables are acknowledging by absence (when this.cards changes – the appearance re-renders).

We’ll about charge displayInitialDeck() to run aback our appliance gets created at the actual beginning. As a result, we’ll run the adjustment in the instance’s created() lifecycle angle which is the adjustment that runs aback an instance or basic gets created for the actual aboriginal time.

Now aback our appliance gets created, the cards abstracts acreage will be busy with all 52 cards in an ordered format. We can now accept our HTML arrangement be able to affectation these cards. Aback we aim to cede a account of elements based on abstracts source, we’ll use Vue’s built-in v-for directive.

In our index.html file, we’ll acknowledge a v-for charge on the markup associated with creating a agenda aspect (i.e. the <div class=”card”></div> element).

The v-for charge requires the syntax of account in the items arrangement that’s actuality common over. We’ll acknowledge the account with an alias of agenda as the account that’s actuality iterated. For anniversary agenda item, we’ll bind the ethics of the agenda rank and clothing on to the element. This now updates our index.html book to the following:

There’s a few things to agenda here.

Though the codicillary chic bounden we’ve set up aloft works well, we can accomplish it a little easier to read. Instead of accepting our agenda chic argumentation defined on the arrangement alone, we can acquaint a abstracts acreage to advice us. We’ll acquaint a suitColor commodity in our instance’s abstracts acreage like so:

In our rendered agenda account elements, we can now specify our codicillary chic bounden artlessly with :class=”suitColor[card.suit]”:

Now, aback we run our appliance – we’ll be displayed with the absolute accouter in the antecedent non confused state!

Here’s a active appliance at this actual moment:

With our accouter now actuality initialized in our app, we can abode how we aim to actually drag the deck. We’ll authorize our own adjustment to accomplish this.

Our agenda elements are actuality rendered from the items in the cards array. A able drag will entail the reordering of the elements in the arrangement in a accidental manner. Reordering elements in an arrangement is simple, but to do so in a accidental abode requires some thought.

Though there are abounding means to adjure a shuffle, not all do it in an able and accidental manner. A accepted and reliable adjustment generally accepted to conduct a accidental drag is the Fisher-Yates algorithm (or additionally accepted as the Knuth algorithm).

Though we won’t go into too abundant detail, we’ll highlight how to assemble a Fisher-Yates shuffle. First, we’ll actualize a adjustment amenable in accomplishing this, alleged shuffleDeck():

We’ll body out the shuffleDeck() adjustment footfall by footfall afore announcement how the absolute adjustment will be laid out.

The Fisher-Yates algorithm involves looping through and ambiguity anniversary aspect in a abstracts array. To begin, we’ll actualize a for bend that loops through every account in the cards array. We’ll activate the bend by ambience the iterator to this.cards.length — 1, again cutback by one up to the point it hits 0.

The drag will aboriginal absorb acrimonious a accidental aspect in the arrangement to shuffle. This can be accomplished by free a accidental cardinal amid 0 and the common arrangement breadth with Math.floor(Math.random() * i). This would about accord us a basis amid 0 and the actual breadth of the arrangement we appetite to shuffle. We’ll accredit this accidental cardinal to a capricious alleged randomIndex:

We’ll again attending to get the agenda account in the arrangement that’s currently actuality common over (i.e. the accepted agenda item) and bandy that accepted agenda account with the account retrieved from the randomIndex. To be able to anon bandy amid two elements:

Traditionally, we could accomplish this by accomplishing article like:

When it comes to re-rendering the appliance UI with the new changes, the aloft won’t work. This is because Vue cannot aces up the changes fabricated aback we anon set the amount of an arrangement account or adapt its length. To be able to anon amend the amount of an arrangement abstracts item, we’ll charge to use the Vue.set() method.

Vue.set() takes three arguments – 1) the arrangement actuality updated, 2) the key of the basis that is to be updated, and 3) the new value. For example, we can amend the aboriginal account in the apparel arrangement with a 🦆 like so:

In our shuffleDeck() method, we’ll use Vue.set() alert to bandy the advised elements. This makes the completed shuffleDeck() adjustment attending like the following:

The aboriginal Vue.set() adjustment sets the amount of the agenda account in the accepted basis to be according to the account for the randomIndex. The additional Vue.set() adjustment sets the amount of the arrangement account of the randomIndex to be according to the acting variable.

And that’s it! We can now actualize the alarm to activity that will run the shuffleDeck() adjustment aback clicked.

We’ll acquaint the on to adjure a drag anon aloft the accouter of cards. In our HTML markup, we’ll abode this on aspect aural a <div class=”main-ons”></div> element:

We’ve declared a bang accident adviser on the on aspect with @click=”shuffleDeck” which sets a bang accident abettor to alarm the shuffleDeck() adjustment aback triggered. Aback we bang this Drag on, our accouter of cards will now drag in-place!

Awesome! With every click, we can apprehension that every distinct agenda in the accouter changes. Though the cards are actuality re-ordered, the re-rendering that occurs with every drag happens instantaneously. For us to be able to beam how the cards are alteration places, we can use Vue Transitions to see how the elements are actuality re-ordered.

Here’s our active appliance at this moment in time:

Vue provides altered means for us to acquaint transitions, such as transitions for a distinct node, transitions for assorted nodes area abandoned 1 is actuality rendered at a time, and transitions for a account of elements. Our accouter of cards uses the v-for charge to cede a account of agenda items, so we’ll attending to administer a Account Move Alteration to breathing the changes in position of anniversary agenda item.

To accomplish this, we’ll change the <div class=”decks”></div> aspect to instead be a transition-group aspect that acts as adhesive to the v-for account (i.e. the accouter of cards). As we acknowledge the transition-group, we’ll bind a alteration name of shuffleSpeed (with :name=”shuffleSpeed”) and accompaniment that the alteration accumulation should be rendered as a div aspect (with tag=”div”):

In our Vue instance, we’ll acknowledge a shuffleSpeed abstracts acreage and set a cord amount of shuffleMedium. With this, we’ll be able to ascendancy the acceleration of transitions with which we’ll see shortly.

When the appliance loads, the transition-group that wraps the accouter of cards will accept a name aspect amount of shuffleMedium. Based on the name of the transition, Vue will automatically admit if any CSS transitions/animations accept been specified. Aback we aim to adjure a alteration for the movement of items in the list; Vue will attending for a defined CSS alteration forth the curve of shuffleMedium-move (where shuffleMedium is the name accustomed to our alteration group).

In the styles.css stylesheet provided in our app, there currently already exists three classes (shuffleSlow-move, shuffleMedium-move, and shuffleFast-move) anniversary amenable in applying a CSS transition. Anniversary of these classes accept the aforementioned blazon but a altered alteration duration.

With our CSS transitions already added, our agenda elements will now alteration appropriately amid locations aback a drag is invoked!

How air-conditioned is that! Let’s now attending to accord the user the best to behest how fast or apathetic they’d appetite the ambiguity to booty place.

The transition-group aspect initially has its name set to a shuffleSpeed abstracts amount (which is initialized with shuffleMedium). To acquiesce the user to change the alteration speed, we about would charge to acquiesce the user to change the amount of shuffleSpeed.

First affair we’ll do is cede three ons that are labelled Slow, Medium, and Fast. We’ll abode these ons aural a <div class=”speed-ons”></div> element, amid anon aloft the ‘Shuffle’ on.

In anniversary alien on, we’ve defined a codicillary chic bounden to conditionally add a .is-light chic depending on the amount of shuffleSpeed. .is-light is a Bulma chic that adds a blah accomplishments to the on. We’ve artlessly set our conditionals to accompaniment that the .is-light chic should be added to the non-active ons.

In anniversary on aspect additionally exists a bang accident adviser that sets the shuffleSpeed acreage to the actual advised acceleration (e.g. beat on ‘Slow’ sets shuffleSpeed to shuffleSlow). With our altered CSS transitions already prepared, we’ll now be able to ascendancy the acceleration of shuffling.

Since anniversary acceleration on aspect is actual agnate to one another, we can abate the alliteration in our HTML markup. To advice us, we’ll acquaint an arrangement labelled shuffleTypes in our Vue instance that contains anniversary accessible blazon of shuffle:

In our HTML markup, we can use the v-for charge to bend through anniversary accessible drag blazon and bind the agnate information:

This makes our markup a little cleaner and achieves the aforementioned result.

We’ve about completed our app! The aftermost few things we’ll add is a ‘Reset’ on to acquiesce the user to displace a confused accouter aback to its aboriginal state, and a adverse to calculation the cardinal of shuffles conducted.

For the adeptness to displace the accouter aback to its antecedent state, we’ll acquaint a ‘Reset’ on alongside the ‘Shuffle’ on.

In the anew added ‘Reset’ on, we’ve declared v-if=”isDeckShuffled” on the element. v-if is a charge that conditionally renders an aspect based on the truthiness of the account specified. In this case, we’re advertence that the ‘Reset’ on should abandoned be apparent aback the isDeckShuffled abstracts acreage is true. We’ll use this abstracts acreage to abandoned cede the ‘Reset’ on aback the accouter has been confused (i.e. aback the accouter is not in the antecedent state).

We’ll acquaint the isDeckShuffled acreage in our instance abstracts accumulating and initialize it with a amount of false. At the end of the shuffleDeck() method, we’ll set the amount of isDeckShuffled to accurate to acknowledge that our accouter of cards has been shuffled. In the displayInitialDeck() method, we’ll displace the isDeckShuffled acreage aback to apocryphal aback in this accompaniment the accouter isn’t confused any longer.

We’ll now be able to displace a confused accouter aback to its antecedent state. The aftermost affair we’ll add is a adverse that counts the cardinal of after shuffles the user makes.

Let’s acquaint a shuffleCount abstracts acreage amenable in tracking the cardinal of after shuffles. We’ll initialize this abstracts amount with 0. Aback a drag is conducted (i.e. shuffleDeck() is called), we’ll accession shuffleCount by 1. Aback the accouter is displace aback to its antecedent accompaniment (i.e. displayInitialDeck() is called), we’ll set the amount of shuffleCount aback to 0.

With these changes, our Vue instance in its absoluteness will now attending like the following:

We’ll now add a <div class=”count-section”></div> aspect at the alpha of our markup. This aspect will be actually positioned to the top appropriate bend of our UI, and will bind the amount of shuffleCount by specifying: # of Shuffles: {{ shuffleCount }}.

Our appliance UI (i.e. the <div id=”app”></div> element) in its absoluteness will be:

Our appliance is now complete! With the contempo changes made, we’ll be able to clue the cardinal of after shuffles a user makes and accept the adeptness to displace a confused accouter aback to its antecedent state.

Here’s the complete application:

Without acclamation CSS styling, we absolved through architecture a UI that allows us to drag a accouter of cards, with the advice of the Fisher-Yates shuffle.

The absolute app, forth with anniversary adaptation of the app as we congenital it through this tutorial can additionally be begin on Github at the awesome-fullstack-tutorials repo:
