ember.js

Pros of React

• Simpler learning curve and easier to get started
• More flexible and can be used for various types of applications
• Larger ecosystem and community support

Cons of React

• Requires additional libraries for full-featured applications
• Less opinionated, which can lead to inconsistent code patterns
• More frequent breaking changes between major versions

Code Comparison

React component:

function Welcome(props) {
  return <h1>Hello, {props.name}</h1>;
}

Ember component:

import Component from '@glimmer/component';

export default class Welcome extends Component {
  <template>
    <h1>Hello, {{@name}}</h1>
  </template>
}

Both frameworks use component-based architecture, but React uses JSX for templating within JavaScript, while Ember uses a separate template syntax. React's approach is more flexible but can lead to mixing of concerns, whereas Ember's structure enforces a clearer separation between logic and presentation.

React's simplicity and flexibility have contributed to its wider adoption, but Ember's conventions and built-in features can lead to more consistent and maintainable code in large applications. The choice between the two often depends on project requirements and team preferences.

Pros of Vue

• Smaller learning curve and easier to get started
• More flexible and less opinionated, allowing for gradual adoption
• Lighter weight with better performance for smaller applications

Cons of Vue

• Less comprehensive ecosystem and tooling compared to Ember
• Fewer built-in conventions, requiring more decision-making for larger projects
• Less suitable for complex, large-scale applications out of the box

Code Comparison

Vue component:

<template>
  <div>{{ message }}</div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello Vue!'
    }
  }
}
</script>

Ember component:

import Component from '@glimmer/component';

export default class HelloComponent extends Component {
  message = 'Hello Ember!';
}

<div>{{this.message}}</div>

Vue uses a single-file component structure, combining template, script, and style in one file. Ember separates the JavaScript and template into different files, following a more structured approach. Vue's syntax is generally more concise, while Ember's conventions provide a more standardized structure for larger applications.

Pros of Angular

• More comprehensive framework with built-in features like dependency injection and TypeScript support
• Larger community and ecosystem, with more third-party libraries and resources
• Better performance for large-scale applications due to its architecture and change detection mechanism

Cons of Angular

• Steeper learning curve, especially for developers new to TypeScript
• More complex setup and configuration compared to Ember's convention-over-configuration approach
• Larger bundle size, which can impact initial load times for applications

Code Comparison

Angular component:

@Component({
  selector: 'app-example',
  template: '<h1>{{title}}</h1>'
})
export class ExampleComponent {
  title = 'Hello, Angular!';
}

Ember component:

import Component from '@glimmer/component';

export default class ExampleComponent extends Component {
  title = 'Hello, Ember!';
}

<h1>{{this.title}}</h1>

Both frameworks use component-based architectures, but Angular combines the template and logic in a single file using TypeScript, while Ember separates them into JavaScript and Handlebars files. Angular's approach may be more concise for small components, but Ember's separation can improve maintainability for larger components.

Pros of Svelte

• Smaller bundle size and faster runtime performance
• Simpler learning curve with less boilerplate code
• Compile-time approach, resulting in less work for the browser

Cons of Svelte

• Smaller ecosystem and community compared to Ember
• Fewer built-in features and conventions
• Less suitable for large, complex applications

Code Comparison

Svelte component:

<script>
  let count = 0;
  function increment() {
    count += 1;
  }
</script>

<button on:click={increment}>
  Clicks: {count}
</button>

Ember component:

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { action } from '@ember/object';

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

  @action
  increment() {
    this.count += 1;
  }
}

<button {{on "click" this.increment}}>
  Clicks: {{this.count}}
</button>

Svelte's syntax is more concise and requires less setup, while Ember follows a more structured approach with decorators and separate template files.

Pros of Alpine

• Lightweight and minimal, with a small learning curve
• Easy to integrate into existing projects without a full rewrite
• Doesn't require a build step, making it simple to use in any environment

Cons of Alpine

• Limited ecosystem and fewer advanced features compared to Ember
• Less suitable for large, complex applications
• Lacks built-in routing and state management solutions

Code Comparison

Ember.js component:

import Component from '@glimmer/component';
import { action } from '@ember/object';

export default class Counter extends Component {
  count = 0;

  @action
  increment() {
    this.count++;
  }
}

Alpine.js component:

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

Alpine provides a more concise, HTML-centric approach, while Ember offers a more structured, JavaScript-based component system. Alpine's simplicity makes it easier to get started, but Ember's architecture is better suited for larger applications with complex state management and routing needs.

Pros of Preact

• Lightweight and fast: Preact has a much smaller bundle size (3KB) compared to Ember's larger footprint
• Simple API: Easier to learn and use, especially for developers familiar with React
• Better performance: Faster rendering and updates due to its minimal architecture

Cons of Preact

• Less comprehensive: Lacks built-in features and conventions that Ember provides out-of-the-box
• Smaller ecosystem: Fewer plugins, addons, and community resources compared to Ember's mature ecosystem
• Limited built-in tooling: Requires additional setup for routing, state management, and other features

Code Comparison

Preact component:

import { h, Component } from 'preact';

class Greeting extends Component {
  render({ name }) {
    return <h1>Hello, {name}!</h1>;
  }
}

Ember component:

import Component from '@ember/component';
import { computed } from '@ember/object';

export default Component.extend({
  greeting: computed('name', function() {
    return `Hello, ${this.get('name')}!`;
  })
});
