Raw Blame History

Component Party 🎉

Web component JS frameworks quick overview by their syntax and features

Website: https://component-party.pages.dev

Why ?

Many JS developers don't have a good overview of every existing JS framework with their own syntax and features. How do we solve this ? Developers love having framework overview by examples. It's a quick introduction before going deeper.

Roadmap

Add Angular support
Add SolidJS support
Add Preact support
Add Alpine support
Website (built with Astro)
Add React support
Add Svelte support
Add Vue 3 support

Contributing

This site is built with Astro. Site content is written in Markdown format located in content. For simple edits, you can directly edit the file on GitHub and generate a Pull Request.

For local development, pnpm is preferred as package manager:

pnpm i
pnpm run dev

This project requires Node.js to be v14.0.0 or higher, because we use new JavaScript features in our code, such as optional chaining.

Reactivity

Declare state

Svelte

<script>
	let name = 'John';
	console.log(name); // John
</script>

React

import { useState } from 'react';

export default function Name() {
	const [name] = useState('John');
	console.log(name); // John
}

Vue 3

<script setup>
import { ref } from 'vue';
const name = ref('John');
console.log(name.value); // John
</script>

Angular

import { Component, Input } from '@angular/core';

@Component({
	selector: 'app-name',
})
export class NameComponent {
	@Input() name: string = 'John';

	constructor() {
		console.log(this.name);
	}
}

Update state

Svelte

<script>
	let name = 'John';
	name = 'Jane';
	console.log(name); // Jane
</script>

React

import { useState } from 'react';

export default function Name() {
	const [name, setName] = useState('John');
	setName('Jane');

	console.log(name); // Jane
}

Vue 3

<script setup>
import { ref } from 'vue';
const name = ref('John');
name.value = 'Jane';
console.log(name.value); // Jane
</script>

Angular

import { Component, Input } from '@angular/core';

@Component({
	selector: 'app-name',
})
export class NameComponent {
	@Input() name: string = 'John';

	constructor() {
		this.name = 'Jane';
		console.log(this.name);
	}
}

Computed state

Svelte

<script>
	let count = 10;
	$: doubleCount = count * 2;
	console.log(doubleCount); // 20
</script>

React

import { useState, useMemo } from 'react';

export default function DoubleCount() {
	const [count] = useState(10);
	const doubleCount = useMemo(() => count * 2, [count]);
	console.log(doubleCount); // 20
	return <div />;
}

Vue 3

<script setup>
import { ref, computed } from 'vue';
const count = ref(10);
const doubleCount = computed(() => count.value * 2);
console.log(doubleCount.value); // 20
</script>

<template>
  <div />
</template>

Angular

import { Component, OnInit, Input, Pipe, PipeTransform, ChangeDetectionStrategy } from '@angular/core';

@Pipe({
	name: 'double',
})
export class DoubleCountPipe implements PipeTransform {
	transform(value: number): number {
		return value * 2;
	}
}

@Component({
	selector: 'app-doublecount',
	template: ' <div></div>',
	changeDetection: ChangeDetectionStrategy.OnPush,
})
export class DoublecountComponent implements OnInit {
	@Input() count: number = 10;

	constructor() {}
}

Templating

Minimal template

Svelte

<h1>Hello world</h1>

React

export default function HelloWorld() {
	return <h1>Hello world</h1>;
}

Vue 3

<template>
  <h1>Hello world</h1>
</template>

Angular

Styling

Svelte

<h1 class="title">Hello world</h1>
<button style="font-size: 10rem;">I am a button</button>

<style>

		color: red;
	}
</style>

React

export default function HelloWorld() {
	// how do you declare title class ??

	return (
		<>
			<h1 className="title">Hello world</h1>
			<button style={{ 'font-size': '10rem' }}>I am a button</button>
		</>
	);
}

Vue 3

<template>
  <h1 class="title">
    Hello world
  </h1>
  <button style="font-size: 10rem">
    I am a button
  </button>
</template>

<style scoped>
