AlpineJS

Beautifully integrate your client-side JavaScript and CBWIRE using AlpineJS.

Many page interactions don't warrant a full server roundtrip, such as toggling a modal or a hidden element. In these instances, we recommend using .

AlpineJS allows you to add JavaScript behavior directly into your markup in a declarative way. If you are familiar with VueJS, Alpine should feel similar.

Installation

<head>
    <script src="//unpkg.com/alpinejs" defer></script>
    <!-- The "defer" attribute is important to ensure Alpine waits for CBWIRE to load first. -->
</head>

Templates

Below is an example of using to toggle a list on the page.

<div>
    <div x-data="{ open: false }">
        <button @click="open = true">Show More...</button>
 
        <ul x-show="open" @click.away="open = false">
            <li><button wire:click="archive">Archive</button></li>
            <li><button wire:click="delete">Delete</button></li>
        </ul>
    </div>
</div>

You need CBWIRE v2.3.6 or greater to use entangle.

CBWIRE has a powerful entangle() method that allows you to "entangle" a CBWIRE and AlpineJS data property. With entanglement, both client-side and server-side properties are instantly synchronized, regardless of whether the value was changed server-side in CFML or client-side using JavaScript.

This provides data model binding both client-side and server-side.

// wires/Counter.cfc
component extends="cbwire.models.Component" {

    data = {
        "counter": 0
    };

    function increment() {
        data.counter += 1;
    }
}

And now, our template:

<!--- views/wires/counter.cfm --->
<cfoutput>
    <div x-data="{ counter: #entangle( 'counter' )# }">
        <div>CBWIRE value: #args.counter#</div>
        <div>AlpineJS value: <span x-html="counter"></span></div>
        
        <button
            wire:click="increment"
            type="button">Increment with CBWIRE</button>
        
        <button
            @click="counter += 1"
            type="button">Increment with AlpineJS</button>
    </div>
</cfoutput>

We define an AlpineJS property named counter and then call the built-in CBWIRE method entangle(), passing it the name of the server-side data property we want to bind with.

<div x-data="{ counter: #entangle( 'counter' )# }">

Next, we are incrementing our Counter in two separate ways:

<button wire:click="increment" type="button">Increment with CBWIRE</button>
<button @click="counter += 1" type="button">Increment with AlpineJS</button>

Updating CBWIRE server-side on every AlpineJS property change is optional. You can also delay the server-side updates until the next CBWIRE request that goes out by chaining a .defer modifier like so.

<div x-data="{ counter: #entangle( 'counter' )#.defer }">

You need CBWIRE v2.3.6 or greater to use entangle.

This provides data model binding both client-side and server-side.

Consider this simple Counter :

// wires/Counter.cfc
component extends="cbwire.models.Component" {

    data = {
        "counter": 0
    };

    function increment() {
        data.counter += 1;
    }
}

And now, our template:

<!--- views/wires/counter.cfm --->
<cfoutput>
    <div x-data="{ counter: #entangle( 'counter' )# }">
        <div>CBWIRE value: #args.counter#</div>
        <div>AlpineJS value: <span x-html="counter"></span></div>
        
        <button
            wire:click="increment"
            type="button">Increment with CBWIRE</button>
        
        <button
            @click="counter += 1"
            type="button">Increment with AlpineJS</button>
    </div>
</cfoutput>

We define an AlpineJS property named counter and then call the built-in CBWIRE method entangle(), passing it the name of the server-side data property we want to bind with.

<div x-data="{ counter: #entangle( 'counter' )# }">

Next, we are incrementing our Counter in two separate ways:

Incrementing the counter by calling the increment using CBWIRE
Incrementing the AlpineJS property counter value in JavaScript, triggering an immediate update to the server and re-rendering of the Counter .

<button wire:click="increment" type="button">Increment with CBWIRE</button>
<button @click="counter += 1" type="button">Increment with AlpineJS</button>

<div x-data="{ counter: #entangle( 'counter' )#.defer }">
