Pros of Vue

• More mature and stable ecosystem with extensive documentation
• Wider adoption and community support
• Includes both Options API and Composition API, offering flexibility

Cons of Vue

• Larger bundle size due to inclusion of both APIs
• Steeper learning curve for beginners due to multiple ways of doing things
• Slower release cycle for new features

Code Comparison

Vue (Options API):

export default {
  data() {
    return { count: 0 }
  },
  methods: {
    increment() {
      this.count++
    }
  }
}

Composition API:

import { ref } from 'vue'

export default {
  setup() {
    const count = ref(0)
    const increment = () => count.value++
    return { count, increment }
  }
}

Key Differences

• Composition API focuses on composable functions, while Vue core includes both APIs
• Composition API allows for better code organization and reusability
• Vue core provides a more complete framework experience out of the box

Use Cases

• Choose Vue for full-featured applications with diverse requirements
• Opt for Composition API when building complex, logic-heavy components or when migrating from Vue 2 to Vue 3

Community and Support

• Vue has a larger community and more third-party libraries
• Composition API is gaining traction, especially among experienced Vue developers

Pros of Angular

• Full-featured framework with built-in tools for routing, forms, and HTTP requests
• Dependency injection system for better modularity and testability
• TypeScript support out of the box, providing strong typing and improved tooling

Cons of Angular

• Steeper learning curve due to its comprehensive nature and unique concepts
• Larger bundle size compared to Vue's Composition API
• More opinionated structure, which may limit flexibility in some cases

Code Comparison

Angular component:

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

Vue Composition API:

import { ref } from 'vue';

export default {
  setup() {
    const title = ref('Hello Vue');
    return { title };
  }
}

Summary

Angular is a comprehensive framework offering a full suite of tools and features, while Vue's Composition API focuses on providing a flexible and lightweight approach to building components. Angular's structure and tooling can be beneficial for large-scale applications, but it comes with a steeper learning curve. The Composition API offers a more intuitive and less opinionated way to organize component logic, making it easier to adopt and use in various project sizes.

Pros of Svelte

• Smaller bundle sizes due to compile-time optimization
• Simpler syntax with less boilerplate code
• Built-in state management without additional libraries

Cons of Svelte

• Smaller ecosystem and community compared to Vue
• Less flexibility for complex applications
• Limited tooling and IDE support

Code Comparison

Svelte component:

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

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

Vue Composition API component:

<template>
  <button @click="increment">
    Clicks: {{ count }}
  </button>
</template>

<script>
import { ref } from 'vue'

export default {
  setup() {
    const count = ref(0)
    const increment = () => {
      count.value++
    }
    return { count, increment }
  }
}
</script>

Svelte offers a more concise syntax, with reactive variables and event handling built into the language. The Vue Composition API provides a more explicit approach to reactivity and component logic organization, which can be beneficial for larger applications.

Pros of Preact

• Smaller bundle size and faster performance
• Closer to vanilla JavaScript, with a simpler API
• Compatible with many React libraries and components

Cons of Preact

• Smaller ecosystem and community compared to Vue
• Less comprehensive documentation and learning resources
• Fewer built-in features and tools for complex applications

Code Comparison

Preact:

import { h, render } from 'preact';

function App() {
  return <h1>Hello, World!</h1>;
}

render(<App />, document.body);

Composition API:

<script setup>
import { h } from 'vue'

const App = () => h('h1', 'Hello, World!')
</script>

<template>
  <App />
</template>

Key Differences

• Preact uses a more React-like syntax, while Composition API is Vue-specific
• Preact has a smaller learning curve for developers familiar with React
• Composition API offers more flexibility in organizing component logic
• Preact focuses on simplicity and performance, while Composition API aims to enhance Vue's reactivity system

Use Cases

• Preact: Lightweight applications, progressive enhancement, performance-critical projects
• Composition API: Complex Vue applications, large-scale projects, when leveraging Vue's ecosystem

Pros of Solid

• Smaller bundle size and better performance due to its compilation approach
• No virtual DOM, resulting in faster rendering and updates
• Fine-grained reactivity without the need for hooks or lifecycle methods

Cons of Solid

• Smaller ecosystem and community compared to Vue
• Steeper learning curve for developers familiar with traditional frameworks
• Less mature tooling and documentation

Code Comparison

Solid:

import { createSignal } from "solid-js";

function Counter() {
  const [count, setCount] = createSignal(0);
  return <button onClick={() => setCount(count() + 1)}>{count()}</button>;
}

Vue Composition API:

<script setup>
import { ref } from 'vue'

const count = ref(0)
</script>

<template>
  <button @click="count++">{{ count }}</button>
</template>

Both examples demonstrate a simple counter component, showcasing the different approaches to reactivity and state management in Solid and Vue Composition API. Solid uses signals and fine-grained reactivity, while Vue Composition API utilizes ref for reactive state.
