@askpext/runtime

The official JavaScript runtime adapter for the Extro browser extension framework.

Extro is a Rust-first framework where domain logic lives in Rust (WASM) and JavaScript acts as a thin, reactive adapter for browser APIs and UI.

Installation

npm install @askpext/runtime

Usage

Combined with the extro CLI, use the runtime to initialize your background or content scripts:

import { createEngine } from '@askpext/runtime';
import * as wasm from './pkg/extro_wasm.js'; // Generated by extro build

// Initialize the reactive engine
const engine = await createEngine(() => wasm);

// Dispatch a command to the Rust core
const result = await engine.dispatch({
  surface: 'Background',
  action: 'SyncState',
  snapshot: { url: '...', title: '...' }
});

console.log(result.message);

Features

• WASM Interop: Seamless bridging between JS and the Extro Rust core.
• Structured Logging: Built-in developer-friendly logging.
• Agent-Ready: Standardized execution patterns that AI agents can easily hook into.
