Divine.js 🎨

Divine.js is a next-generation, high-performance design tool built from the ground up with WebGPU, delivering native-level performance for professional graphic workflows directly in your browser.

Status: This project is under active development. We're building the future of web-based design tools.

🚀 Why Divine.js?

Traditional web design tools hit performance ceilings with Canvas 2D or WebGL. Divine.js breaks through these limits by leveraging WebGPU, offering:

• GPU-Powered Everything - Rendering, filtering, compositing - all accelerated
• Real-Time Performance - Smooth 60fps+ editing even with complex 4K+ documents
• Professional Format Support - Work directly with industry-standard files
• Framework Agnostic - Pure WebGPU, no heavy dependencies

✨ Core Features

🖼 Extensive Format Support

Import and edit professional design files directly:

Format	Status	Notes
PNG/JPEG/WebP	✅ Full Support	Hardware-accelerated decoding
SVG	✅ Full Support	GPU-accelerated vector rendering
PDF	✅ Supported	Vector & raster content extraction
PSD	✅ Supported	Layer preservation & blending modes
AI	⚠️ Limited	Via export conversion (see notes)

Note on AI files: Native .ai parsing is challenging. We recommend exporting to SVG/PDF from Illustrator for best results.

⚡ GPU-Accelerated Architecture

Rendering Engine

• Unified WebGPU Pipeline - Single render path for all content types
• SDF Text Rendering - Crisp typography at any scale
• Instanced Drawing - Thousands of objects, minimal draw calls
• Compute Shaders - Real-time filters & effects

Performance Optimizations

• Worker-Based Decoding - Never block the UI thread
• Texture Atlasing - Minimize GPU state changes
• Hierarchical Culling - Only render what's visible
• Incremental Updates - Smart re-rendering

🛠 Designer-Focused Tools

Vector Editing

• Bézier curve manipulation
• Boolean operations
• Path simplification
• Live shape tools

Layer Management

• Full layer stack
• Blending modes
• Layer effects
• Grouping & masking

Typography

• Rich text formatting
• OpenType features
• Text on path
• Variable font support

🚀 Quick Start

Prerequisites

• Browser with WebGPU support (Chrome 113+, Edge 113+, Safari 17+)
• Node.js 18+ & npm/yarn/pnpm

Installation

# Clone the repository
git clone https://github.com/canzoneyu/divine.git
cd divine

# Install dependencies
npm install

# Start development server

npm run build

Basic Usage

import { DesignEditor } from "Divine";

// Initialize with a canvas element
const editor = new DesignEditor({
  canvas: document.getElementById("editor-canvas"),
  backgroundColor: "#ffffff",
  resolution: 2, // Retina support
});

// Load a design file
await editor.loadFile("design.psd");

// Export your work
const pngData = await editor.exportToPNG();
const svgData = await editor.exportToSVG();
