🕷️ Spider React

A production-grade React implementation built from scratch with modern features including Fiber architecture, concurrent rendering, hooks, and server-side rendering capabilities.

🎯 Project Overview

Spider is a complete React library implementation following best practice coding standards. This project aims to provide:

• Fiber Architecture: Modern reconciliation with time-slicing
• Concurrent Features: useTransition, Suspense, and priority-based rendering
• Complete Hooks System: All React hooks with custom hooks support
• Server-Side Rendering: Streaming SSR with selective hydration
• TypeScript First: Fully typed with strict mode
• Production Ready: Comprehensive testing and performance optimization

🚀 Features

✅ Completed

• Project setup and tooling configuration
• Core element and component system
• Basic reconciliation algorithm
• DOM renderer implementation
• Hooks system (useState, useEffect, etc.)
• Fiber architecture
• Concurrent rendering
• Suspense and error boundaries
• Server-side rendering
• Developer tools integration

🔄 In Progress

• Setting up core types and interfaces

📋 Planned

• See our detailed roadmap for complete feature timeline

📦 Packages

Spider is organized as a monorepo with two main packages:

• spider: Core React implementation
• spider-dom: DOM renderer for browser environments

🛠️ Installation

# Install both packages
npm install spider spider-dom

# Or with yarn
yarn add spider spider-dom

📖 Quick Start

import { createElement, useState } from 'spider';
import { createRoot } from 'spider-dom';

function App() {
  const [count, setCount] = useState(0);

  return createElement('div', {}, [
    createElement('h1', {}, 'Hello Spider!'),
    createElement('p', {}, `Count: ${count}`),
    createElement(
      'button',
      {
        onClick: () => setCount(count + 1),
      },
      'Increment'
    ),
  ]);
}

const root = createRoot(document.getElementById('root')!);
root.render(createElement(App));
