Ember Polaris vs Qwik: A Comprehensive Comparison

This website is powered by ItGalaxy.io

In the world of frontend development, Ember Polaris and Qwik represent two different philosophies for building web applications. While Ember Polaris brings modern features to the Ember ecosystem with Glimmer components and strict-mode JavaScript, Qwik offers a revolutionary approach with resumability and instant load times. Let’s explore their differences and use cases.

Core Concepts

Ember Polaris and Qwik take fundamentally different approaches to building web applications:

• Ember Polaris uses a modern, class-based component model with Glimmer templates and strict-mode JavaScript
• Qwik uses resumability and fine-grained lazy loading to achieve instant load times and optimal performance

Reactivity and State Management

State Declaration

Both frameworks offer different ways to declare and manage state:

Ember Polaris’s Approach

// name.gjs
import Component from "@glimmer/component";

export default class NameComponent extends Component {
  name = "John";

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

Ember Polaris uses class-based components with template syntax.

Qwik’s Approach

// Name.tsx
import { component$, useSignal } from "@builder.io/qwik";

export const Name = component$(() => {
  const name = useSignal("John");

  return <h1>Hello {name.value}</h1>;
});

Qwik uses signals and components with fine-grained reactivity.

State Updates

Ember Polaris’s Approach

// name.gjs
import Component from "@glimmer/component";
import { tracked } from "@glimmer/tracking";

export default class CounterComponent extends Component {
  @tracked name = "John";

  constructor(owner, args) {
    super(owner, args);
    this.name = "Jane";
  }

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

Qwik’s Approach

// Name.tsx
import { component$, useTask$, useSignal } from "@builder.io/qwik";

export const Name = component$(() => {
  const name = useSignal("John");

  useTask$(() => {
    name.value = "Jane";
  });

  return <h1>Hello {name.value}</h1>;
});

Computed Properties

Ember Polaris’s Approach

// double-count.gjs
import Component, { tracked } from "@glimmer/component";

export default class DoubleCount extends Component {
  @tracked count = 10;

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

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

Qwik’s Approach

// DoubleCount.tsx
import { component$, useSignal, useComputed$ } from "@builder.io/qwik";

export const DoubleCount = component$(() => {
  const count = useSignal(10);
  const doubleCount = useComputed$(() => count.value * 2);

  return <div>{doubleCount.value}</div>;
});

DOM Manipulation

List Rendering

Ember Polaris’s Approach

// colors.gjs
const colors = ["red", "green", "blue"];

<template>
  <ul>
    {{#each colors as |color|}}
      <li>{{color}}</li>
    {{/each}}
  </ul>
</template>

Qwik’s Approach

// Colors.tsx
import { component$ } from "@builder.io/qwik";

export const Colors = component$(() => {
  const colors = ["red", "green", "blue"];
  return (
    <ul>
      {colors.map((color) => (
        <li key={color}>{color}</li>
      ))}
    </ul>
  );
});

Event Handling

Ember Polaris’s Approach

// counter.gjs
import Component from "@glimmer/component";
import { tracked } from "@glimmer/tracking";
import { on } from "@ember/modifier";

export default class Counter extends Component {
  @tracked count = 0;

  incrementCount = () => this.count++;

  <template>
    <p>Counter: {{this.count}}</p>
    <button {{on "click" this.incrementCount}}>+1</button>
  </template>
}

Qwik’s Approach

// Counter.tsx
import { component$, useSignal, $ } from "@builder.io/qwik";

export const Counter = component$(() => {
  const count = useSignal(0);

  const incrementCount = $(() => {
    count.value++;
  });

  return (
    <>
      <p>Counter: {count.value}</p>
      <button onClick$={incrementCount}>Increment</button>
    </>
  );
});

Form Handling

Text Input

Ember Polaris’s Approach

// input-hello.gjs
import Component from "@glimmer/component";
import { tracked } from "@glimmer/tracking";
import { on } from '@ember/modifier';

export default class InputHello extends Component {
  @tracked text = "Hello World";

  handleInput = (event) => (this.text = event.target.value);

  <template>
    <p>{{this.text}}</p>
    <input value={{this.text}} {{on "input" this.handleInput}} />
  </template>
}

Qwik’s Approach

// InputHello.tsx
import { component$, useSignal } from "@builder.io/qwik";

const InputHello = component$(() => {
  const text = useSignal("");

  return (
    <>
      <p>{text.value}</p>
      <input bind:value={text} />
    </>
  );
});

Lifecycle Management

Component Mounting

Ember Polaris’s Approach

// page-title.gjs
const pageTitle = () => document.title;

<template>
  <p>Page title is: {{(pageTitle)}}</p>
</template>

Qwik’s Approach

// PageTitle.tsx
import { component$, useVisibleTask$, useStore } from "@builder.io/qwik";

export const App = component$(() => {
  const store = useStore({
    pageTitle: "",
  });

  useVisibleTask$(() => {
    store.pageTitle = document.title;
  });

  return <p>Page title: {store.pageTitle}</p>;
});
