Alpine vs Aurelia 2: A Comprehensive Comparison

This website is powered by ItGalaxy.io

In the world of frontend development, Alpine.js and Aurelia 2 represent two different philosophies for building web applications. While Alpine.js is a lightweight framework that brings reactivity directly to your HTML, Aurelia 2 offers a powerful, convention-based approach with modern features. Let’s explore their differences and use cases.

Core Concepts

Alpine.js and Aurelia 2 take fundamentally different approaches to building web applications:

  • Alpine.js enhances existing HTML with directives, making it perfect for adding interactivity to traditional server-rendered applications
  • Aurelia 2 uses a convention-based approach with powerful templating and dependency injection

Reactivity and State Management

State Declaration

Both frameworks offer different ways to declare and manage state:

Alpine’s Approach

<h1 x-data="{ name: 'John' }" x-text="name"></h1>

Alpine.js uses a simple directive-based approach with x-data for state management.

Aurelia 2’s Approach

// name.ts
export class NameCustomElement {
  name = "John";
}

// name.html
<h1>Hello ${name}</h1>;

Aurelia 2 uses class-based components with automatic data binding.

State Updates

Alpine’s Approach

<h1 x-data="{ name: 'John' }" x-init="name = 'Jane'" x-text="name"></h1>

Aurelia 2’s Approach

// name.ts
export class NameCustomElement {
  name = "John";

  constructor() {
    this.name = "Jane";
  }
}

// name.html
<h1>Hello ${name}</h1>;

Computed Properties

Alpine’s Approach

<h1
  x-data="{
  count : 10,
  get doubleCount() { return this.count * 2 }
}"
  x-text="doubleCount"
></h1>

Aurelia 2’s Approach

// double-count.ts
export class DoubleCountCustomElement {
  count = 10;

  get doubleCount() {
    return this.count * 2;
  }
}

// double-count.html
<div>${doubleCount}</div>;

DOM Manipulation

List Rendering

Alpine’s Approach

<ul x-data="{ colors: ['red', 'green', 'blue'] }">
  <template x-for="color in colors">
    <li x-text="color"></li>
  </template>
</ul>

Aurelia 2’s Approach

// colors.ts
export class ColorsCustomElement {
  colors = ['red', 'green', 'blue'];
}

// colors.html
<ul>
  <li repeat.for="color of colors">${color}</li>
</ul>

Conditional Rendering

Alpine’s Approach

<div
  x-data="{
  TRAFFIC_LIGHTS: ['red', 'orange', 'green'],
  lightIndex: 0,
  get light() { return this.TRAFFIC_LIGHTS[this.lightIndex] },
  nextLight() {
    this.lightIndex = (this.lightIndex + 1) % this.TRAFFIC_LIGHTS.length;
  }
}"
>
  <button x-on:click="nextLight">Next light</button>
  <p>Light is: <span x-text="light"></span></p>
  <p>
    You must
    <span x-show="light === 'red'">STOP</span>
    <span x-show="light === 'orange'">SLOW DOWN</span>
    <span x-show="light === 'green'">GO</span>
  </p>
</div>

Aurelia 2’s Approach

// traffic-light.ts
export class TrafficLightCustomElement {
  TRAFFIC_LIGHTS = ['red', 'orange', 'green'];
  lightIndex = 0;

  get light() {
    return this.TRAFFIC_LIGHTS[this.lightIndex];
  }

  nextLight() {
    this.lightIndex = (this.lightIndex + 1) % this.TRAFFIC_LIGHTS.length;
  }
}

// traffic-light.html
<button click.trigger="nextLight()">Next light</button>
<p>Light is: ${light}</p>
<p switch.bind="light">
  You must
  <span case="red">STOP</span>
  <span case="orange">SLOW DOWN</span>
  <span case="green">GO</span>
</p>

Event Handling

Click Events

Alpine’s Approach

<div x-data="{ count: 0 }">
  <p>Counter: <span x-text="count"></span></p>
  <button x-on:click="count++">+1</button>
</div>

Aurelia 2’s Approach

// counter.ts
export class CounterCustomElement {
  count = 0;

  incrementCount() {
    this.count++;
  }
}

// counter.html
<p>Counter: ${count}</p>
<button click.trigger="incrementCount()">+1</button>

Form Handling

Text Input

Alpine’s Approach

<div x-data="{ text: 'Hello World' }">
  <p x-text="text"></p>
  <input x-model="text" />
</div>

Aurelia 2’s Approach

// input-hello.ts
export class InputHelloCustomElement {
  text = 'Hello World';
}

// input-hello.html
<p>${text}</p>
<input value.bind="text" />

Lifecycle Management

Component Mounting

Alpine’s Approach

<p
  x-data="{ pageTitle: '' }"
  x-init="$nextTick(() => { pageTitle = document.title })"
>
  Page title: <span x-text="pageTitle"></span>
</p>

Aurelia 2’s Approach

// page-title.ts
export class PageTitleCustomElement {
  pageTitle = "";

  attached() {
    this.pageTitle = document.title;
  }
}

// page-title.html
<p>Page title is: ${pageTitle}</p>;

Performance and Bundle Size
