Pylon Mobile Starter

Cross-platform consumer app starter built on Pylon. One realtime backend, three native frontends:

• apps/expo — React Native + Expo. Runs on iOS, Android, and the web from a single codebase. Uses @pylonsync/react-native for live queries.
• apps/swift — Native SwiftUI app targeting iOS and macOS (universal binary). Talks to Pylon over REST + WebSockets directly from Swift.
• apps/tauri — Tauri 2 app targeting macOS, Windows, Linux desktop and (with the mobile target enabled) iOS + Android. Vanilla TypeScript frontend talking to Pylon over the public REST API.

All three apps target the same backend (backend/) so you can run them in parallel and watch state sync across every device.

Demo app

A simple shared notes app:

• Sign up / log in
• Create, edit, delete notes
• Real-time updates across every signed-in device
• Tags + search

Getting started

# Bring up the Pylon backend
cd backend
pylon dev

# In another terminal — Expo
cd apps/expo
bun install
bun start              # press i for iOS, a for Android, w for web

# Native Swift
open apps/swift/PylonNotes.xcodeproj
# select target (iOS or My Mac (Designed for Catalyst)) → Run

# Tauri
cd apps/tauri
bun install
bun tauri dev          # desktop
bun tauri ios dev      # iOS
bun tauri android dev  # Android

Architecture

Pylon backend exposes:

• POST /api/auth/password/{login,register} for auth
• POST /api/entities/Note for inserts (CRUD)
• POST /api/search/Note for full-text search
• WS / for live query subscriptions

The Expo app uses @pylonsync/react-native so live queries feel native. Swift and Tauri implement a thin REST + WebSocket client directly — see apps/swift/PylonNotes/PylonClient.swift and apps/tauri/src/lib/pylon.ts.
