Quick Start

CDN (Simplest)

<script src="https://unpkg.com/@lokascript/core/dist/lokascript-browser.js"></script>

<button _="on click toggle .active on me">
  Click me
</button>

npm + Vite (Recommended)

npm install @lokascript/core @lokascript/vite-plugin
// vite.config.js
import { lokascript } from '@lokascript/vite-plugin';

export default {
  plugins: [lokascript()]
};

The Vite plugin automatically scans your code and generates a minimal bundle with only the commands you use.

Events First

Send, receive, filter, queue, and debounce events with ease. Chain events together for complex interactions.

Async Built-In

No promises, async/await, or callback hell. LokaScript transparently handles asynchronous behavior.

~85% Compatibility

Compatible with most _hyperscript code. Migrate existing projects with minimal changes.

Tree-Shakeable

Only include the commands you use. The Vite plugin generates optimal bundles automatically.

Semantic Parser

AI-friendly parsing that understands intent across all 24 languages with confidence scoring.

MCP Integration

22 tools for AI assistants: validation, translation, pattern search, and code generation.
