This website is powered by ItGalaxy.io

In the world of frontend development, Vue 2 and Aurelia 2 represent two different approaches to building web applications. While Vue 2 is a mature framework with a rich ecosystem, Aurelia 2 offers a modern, standards-compliant approach with powerful data binding capabilities. Let’s explore their differences and use cases.

Core Concepts

Vue 2 and Aurelia 2 take fundamentally different approaches to building web applications:

  • Vue 2 uses a progressive framework approach with a virtual DOM and component-based architecture
  • Aurelia 2 emphasizes standards compliance and convention over configuration with powerful data binding

Reactivity and State Management

State Declaration

Both frameworks offer different ways to declare and manage state:

Vue 2’s Approach

<script>
export default {
  data() {
    return {
      name: "John",
    };
  },
};
</script>

<template>
  <h1>Hello {{ name }}</h1>
</template>

Vue 2 uses a component-based approach with a data function.

Aurelia 2’s Approach

<!-- name.html -->
<h1>Hello ${name}</h1>

<!-- name.ts -->
export class NameCustomElement { name = 'John'; }

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

State Updates

Vue 2

<script>
export default {
  data() {
    return {
      name: "John",
    };
  },
  created() {
    this.name = "Jane";
  },
};
</script>

<template>
  <h1>Hello {{ name }}</h1>
</template>

Aurelia 2

<!-- name.html -->
<h1>Hello ${name}</h1>

<!-- name.ts -->
export class NameCustomElement { name = 'John'; constructor() { this.name =
'Jane'; } }

Computed Values

Vue 2

<script>
export default {
  data() {
    return {
      count: 10,
    };
  },
  computed: {
    doubleCount() {
      return this.count * 2;
    },
  },
};
</script>

<template>
  <div>{{ doubleCount }}</div>
</template>

Aurelia 2

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

<!-- double-count.ts -->
export class DoubleCountCustomElement { count = 10; get doubleCount() { return
this.count * 2; } }

DOM Manipulation

List Rendering

Vue 2

<script>
export default {
  data() {
    return {
      colors: ["red", "green", "blue"],
    };
  },
};
</script>

<template>
  <ul>
    <li v-for="color in colors" :key="color">
      {{ color }}
    </li>
  </ul>
</template>

Aurelia 2

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

<!-- colors.ts -->
export class ColorsCustomElement { colors = ['red', 'green', 'blue']; }

Conditional Rendering

Vue 2

<script>
export default {
  data() {
    return {
      TRAFFIC_LIGHTS: ["red", "orange", "green"],
      lightIndex: 0,
    };
  },
  computed: {
    light() {
      return this.TRAFFIC_LIGHTS[this.lightIndex];
    },
  },
  methods: {
    nextLight() {
      this.lightIndex = (this.lightIndex + 1) % this.TRAFFIC_LIGHTS.length;
    },
  },
};
</script>

<template>
  <div>
    <button @click="nextLight">Next light</button>
    <p>Light is: {{ light }}</p>
    <p>
      You must
      <span v-if="light === 'red'">STOP</span>
      <span v-else-if="light === 'orange'">SLOW DOWN</span>
      <span v-else-if="light === 'green'">GO</span>
    </p>
  </div>
</template>

Aurelia 2

<!-- 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>

<!-- 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; } }

Form Handling

Text Input

Vue 2

<script>
export default {
  data() {
    return {
      text: "Hello World",
    };
  },
};
</script>

<template>
  <div>
    <p>{{ text }}</p>
    <input v-model="text" />
  </div>
</template>

Aurelia 2

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

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

Select Input

Vue 2

<script>
export default {
  data() {
    return {
      selectedColorId: 2,
      colors: [
        { id: 1, text: "red" },
        { id: 2, text: "blue" },
        { id: 3, text: "green" },
        { id: 4, text: "gray", isDisabled: true },
      ],
    };
  },
};
</script>

<template>
  <select v-model="selectedColorId">
    <option
      v-for="color in colors"
      :key="color.id"
      :value="color.id"
      :disabled="color.isDisabled"
    >
      {{ color.text }}
    </option>
  </select>
</template>

Aurelia 2

<!-- color-select.html -->
<select value.bind="selectedColorId">
  <option value="">Select A Color</option>
  <option
    repeat.for="color of colors"
    value.bind="color.id"
    disabled.bind="color.isDisabled"
  >
    ${color.text}
  </option>
</select>

<!-- color-select.ts -->
export class ColorSelectCustomElement { selectedColorId = 2; colors = [ { id: 1,
text: 'red' }, { id: 2, text: 'blue' }, { id: 3, text: 'green' }, { id: 4, text:
'gray', isDisabled: true } ]; }

Component Composition

Props

Vue 2

<script>
import UserProfile from "./UserProfile.vue";

export default {
  components: {
    UserProfile,
  },
};
</script>

<template>
  <UserProfile
    name="John"
    :age="20"
    :favorite-colors="['green', 'blue', 'red']"
    is-available
  />
</template>

Aurelia 2

<!-- app.html -->
<user-profile
  name.bind="name"
  age.bind="age"
  favourite-colors.bind="colors"
  is-available.bind="available"
></user-profile>

<!-- app.ts -->
export class AppCustomElement { name = 'John'; age = 20; colors = ['green',
'blue', 'red']; available = true; }
