Quantum Framework

A lightning-fast, signal-based reactive framework for building modern web applications

Getting Started • Documentation • Examples • Roadmap

What is Quantum?

Quantum is a modern JavaScript framework that combines the best ideas from React, Vue, and Solid.js into a cohesive, performant package. Built from scratch with zero dependencies, Quantum delivers blazing-fast performance through signal-based reactivity and compile-time optimizations.

Why Quantum?

🚀 Blazing Fast - 2.7KB gzipped core, signal-based reactivity with zero VDOM overhead
💎 Developer Experience - Familiar JSX/TSX syntax, full TypeScript support, intuitive API
⚡ Smart Compiler - Compile-time optimizations for maximum runtime performance
🎯 Production Ready - Comprehensive test coverage (295/310 tests passing)
🛠️ Complete Tooling - CLI for scaffolding, dev server, and production builds
📦 Batteries Included - Client-side router, state management, CSS-in-JS styling, and more

🚀 Getting Started

Quick Start

Create a new Quantum app in seconds:

# Using npm
npm create quantum-app my-app

# Using pnpm
pnpm create quantum-app my-app

# Using yarn
yarn create quantum-app my-app

Then start developing:

cd my-app
pnpm dev

Choose Your Template

Quantum provides three starter templates:

basic - Minimal setup with JSX (perfect for learning)
typescript - Full TypeScript configuration
full - Feature-rich template with components and styling

create-quantum-app my-app --template typescript

📝 Your First Component

import { signal, computed } from '@quantum/core/reactivity';

export function Counter() {
  const count = signal(0);
  const doubled = computed(() => count.value * 2);

  return (
    <div>
      <h1>Counter: {count}</h1>
      <p>Doubled: {doubled}</p>
      <button onClick={() => count.value++}>Increment</button>
    </div>
  );
}

How It Works

Signals store reactive state
Computed values automatically update when dependencies change
JSX compiles to optimized function calls
No VDOM - direct DOM updates for maximum performance

💡 Core Concepts

Signals

Signals are the fundamental building block of reactivity in Quantum:

import { signal } from '@quantum/core/reactivity';

// Create a signal
const count = signal(0);

// Read value
console.log(count.value); // 0

// Update value
count.value = 10;

// Subscribe to changes
count.subscribe((newValue) => {
  console.log('Count changed:', newValue);
});

Computed Values

Computed values automatically recalculate when their dependencies change:

import { signal, computed } from '@quantum/core/reactivity';

const firstName = signal('John');
const lastName = signal('Doe');

const fullName = computed(() => `${firstName.value} ${lastName.value}`);

console.log(fullName.value); // "John Doe"

firstName.value = 'Jane';
console.log(fullName.value); // "Jane Doe"

Effects

Effects run automatically when their dependencies change:

import { signal, effect } from '@quantum/core/reactivity';

const count = signal(0);

effect(() => {
  console.log('Count is:', count.value);
});

count.value = 5; // Logs: "Count is: 5"

Batch Updates

Batch multiple state updates for optimal performance:

import { signal, batch } from '@quantum/core/reactivity';

const x = signal(0);
const y = signal(0);

batch(() => {
  x.value = 10;
  y.value = 20;
  // Only one re-render happens here
});
