@r1-runtime/kernel

Core OS-like kernel for R1 TauriWeb Runtime — WASM orchestration, VFS, and WASI shim.

Features

• WASM Orchestration: Load and execute WebAssembly modules in a dedicated Worker
• Virtual File System (VFS): OPFS-backed file system with full persistence
• WASI Shim: Complete WASI snapshot_preview1 implementation for Rust std::fs
• SQLite Support: Full syscall support for rusqlite with bundled feature

Installation

npm install @r1-runtime/kernel

Usage

import { VFS, WasmOrchestrator } from '@r1-runtime/kernel';

// Initialize VFS
const vfs = new VFS();
await vfs.init();

// Create orchestrator
const orchestrator = new WasmOrchestrator(vfs);

// Load WASM module
await orchestrator.loadModule('app', '/wasm/app.wasm');

// Call Rust functions
const result = await orchestrator.callFunction('app', 'greet', { name: 'World' });
