Axii

A high-performance frontend framework powered by intelligent reactive data structures.

🚀 Key Features

Efficient Reactive Data Structures

• Smart Incremental Updates: When reactive data changes, Axii performs intelligent incremental computations instead of full recalculations, significantly improving performance for array operations
• No Virtual DOM: Direct and precise DOM updates based on reactive data changes, eliminating the need for diffing processes
• Rich Data Types: Built-in support for reactive collections including RxList, RxMap, RxSet, and specialized RxTime for time-based reactivity

Performance-First Design

• Automatic Optimization: High performance by default without requiring extra developer effort
• Efficient Selection Management: Built-in tools for single and multiple selections that maintain high performance by avoiding unnecessary recalculations
• Smart DOM Updates: Direct attribute updates through atomic reactive data bindings

Advanced Features

• Flexible Component Configuration: Easy exposure of child components and DOM nodes using the as syntax
• Portal Support: Render components under different root nodes, perfect for modals and popups
• Context System: Built-in context support for efficient data passing between components
• Side Effects Management:
  • Support for useEffect and useLayoutEffect
  • Elegant cleanup handling through ManualCleanup class inheritance
  • Automatic cleanup on component destruction

DOM Integration

• Reactive DOM State Wrappers: Built-in reactive wrappers for common DOM states:
  • Element size
  • Position tracking
  • Drag position
  • Scroll position
• Custom State Wrappers: Create custom DOM state reactive wrappers using createStateFromRef

🔧 Installation

npx create-axii-app myapp
Copy

📚 Quick Start

/* @jsx createElement */
import { createRoot, createElement, atom } from 'axii'

function App({}, { createElement }) {
  const name = atom('world')
  const onInput = (e) => name(e.target.value)

  return (
    <div>
      <input value={name} onInput={onInput} />
      <div>Hello, {name}!</div>
    </div>
  )
}

const root = document.getElementById('root')!
const appRoot = createRoot(root)
appRoot.render(<App />)
Copy

💡 Why Axii?

Axii stands out by providing exceptional performance through its intelligent reactive system. While other frameworks often require manual optimization, Axii is designed to be efficient by default, allowing developers to focus on building features rather than optimizing performance.
