Tauri API shims for R1 — drop-in replacements for @tauri-apps/api.

Features

Complete implementations of Tauri APIs that work in the browser:

• File System (fs)
• SQL Database (sql)
• Events (event)
• Dialogs (dialog)
• Path utilities (path)
• OS information (os)
• Clipboard (clipboard)
• Window management (window)
• Key-value store (store)
• Notifications (notification)
• Shell (shell)
• HTTP (http)

Installation

npm install @r1-runtime/apis

Usage

File System

import { readTextFile, writeTextFile, readDir } from '@r1-runtime/apis/fs';

await writeTextFile('notes.txt', 'Hello World');
const content = await readTextFile('notes.txt');
const files = await readDir('/app/data');

SQL Database

import { Database } from '@r1-runtime/apis/sql';

const db = await Database.load('sqlite:app.db');
await db.execute('CREATE TABLE users (id INTEGER, name TEXT)');
await db.execute('INSERT INTO users VALUES (?, ?)', [1, 'Alice']);
const rows = await db.select('SELECT * FROM users');

Events

import { listen, emit } from '@r1-runtime/apis/event';

// Listen for events from Rust
await listen('update', (event) => {
  console.log('Received:', event.payload);
});

// Emit events to Rust
await emit('button-clicked', { id: 123 });

Dialog

import { open, save, message } from '@r1-runtime/apis/dialog';

const file = await open({ multiple: false });
const savePath = await save({ defaultPath: 'document.txt' });
await message('Operation complete!', { title: 'Success' });

Path Utilities

import { appDataDir, join, basename } from '@r1-runtime/apis/path';

const dataDir = await appDataDir();
const filePath = await join(dataDir, 'config.json');
const name = await basename(filePath);

OS Information

import { platform, arch, version } from '@r1-runtime/apis/os';

const os = await platform(); // 'linux', 'darwin', 'windows'
const architecture = await arch(); // 'x86_64', 'aarch64'
const osVersion = await version();

Clipboard

import { writeText, readText } from '@r1-runtime/apis/clipboard';

await writeText('Hello from R1!');
const text = await readText();

Store (Key-Value)

import { Store } from '@r1-runtime/apis/store';

const store = new Store('settings.json');
await store.set('theme', 'dark');
const theme = await store.get('theme');
await store.save();

Available Exports

All APIs support direct imports:
