RxNote

A dual-platform quick note-taking app with QR code and NFC support.

Overview

RxNote lets users create and share notes that can be accessed via QR codes or NFC chips. Notes support markdown content, images, location data, and typed actions (links, WiFi credentials). Access is controlled by visibility settings (public, auth-only, private).

• Backend (/backend) — Next.js app with REST APIs and public note preview pages
• iOS App (/RxNote) — Swift mobile app with App Clips support for QR/NFC scanning

Quick Start

Backend

cd backend
bun install
cp .env.example .env          # fill in credentials
bun run db:push               # push schema to database
bun run dev                   # start dev server at http://localhost:3000

iOS App

1. Copy RxNote/RxNote/Config/Secrets.xcconfig.example to Secrets.xcconfig and add your OAuth client IDs.
2. Open RxNote/RxNote.xcodeproj in Xcode.
3. Build and run (Cmd+R).
