Snap Wasm VDOM

Reactive immediate DOM rendering with Wasm in Zig. Compiles to a small WebAssembly binary.

Features

• DOM rendering: simple immediate mode rendering
• Event System: event handlers with callback support
• Reactive State: state management and automatic re-rendering
• Templating: with Zig's std library formatting and snap.renderTemplate()

Examples

See src/snap-demo.zig for a demo app with a counter and todos.

Quick Start

zig build --release=small
python -m http.server

open localhost:8000 in your browser

Prerequisites

• Zig 0.14.0 or later
• A modern web browser

Architecture

The library is designed around:

1. Virtual DOM: Immutable tree structures representing UI state
2. Immediate Mode: Direct DOM manipulation for simplicity
3. Event System: Type-safe callbacks with context preservation
4. State Management: Reactive updates triggering re-renders
