# Nextcloud Notes Desktop

A desktop client for [Nextcloud Notes](https://apps.nextcloud.com/apps/notes) built with React, TypeScript, Vite, and Electron.

This project started life as a Tauri app and has now been migrated to Electron for desktop runtime support, PDF export, and simpler cross-platform desktop behavior during development.

## What It Does

- Sign in to a Nextcloud server with Notes enabled
- Sync notes from WebDAV and favorite state from the Notes API
- Create, edit, move, rename, and delete notes
- Organize notes into categories, including nested categories
- Mark notes as favorites
- Cache notes locally for faster startup and offline viewing
- Upload and render note attachments
- Preview Markdown while editing
- Export notes to PDF
- Use a focus mode for distraction-free editing

## Current Runtime

- Primary desktop runtime: Electron
- Frontend: React 19 + TypeScript + Vite
- Styling: Tailwind CSS
- Local cache: IndexedDB
- Nextcloud integration:
  - WebDAV for note files, folders, attachments, and category color storage
  - Notes API for favorite metadata

Some Tauri-related code and dependencies are still present in the repository, mainly because parts of the app were built during the earlier Tauri phase. The Electron path is the actively used desktop runtime.

## Requirements

- Node.js 18 or newer
- npm
- A Nextcloud instance with the Notes app enabled

## Install

```bash
npm install
```

## Development

Run the Electron app with the Vite dev server:

```bash
npm run dev:desktop
```

Useful scripts:

```bash
npm run dev:renderer   # Vite frontend only
npm run dev:electron   # Electron only, expects renderer on port 1420
npm run build          # TypeScript + Vite production build
npm run desktop        # Run Electron against the built dist/
npm run dist:dir       # Build an unpacked Electron app in release/
npm run dist:mac       # Build macOS .dmg and .zip packages in release/
npm run dist:win       # Build Windows installer + zip for the current Windows architecture
npm run dist:win:arm64 # Build Windows ARM64 installer + zip in release/
```

## Production-Like Local Run

Build the frontend, then start Electron against the generated `dist/` files:

```bash
npm run build
npm run desktop
```

## First Launch

1. Enter your Nextcloud server URL, for example `https://cloud.example.com`
2. Enter your username
3. Enter your password or, preferably, a Nextcloud app password
4. Wait for the initial sync to finish

Using an app password is strongly recommended.

## Notable Behavior

### Sync model

- Note files are synced through WebDAV
- Favorite status is synced through the Nextcloud Notes API
- Notes are cached locally and can still be viewed when offline
- Background sync runs periodically while the app is open

### PDF export

- In Electron, the toolbar export action saves a PDF directly to disk
- Embedded note images are resolved before export when possible

### Category colors

- Category color preferences are stored in `.category-colors.json` inside your Nextcloud Notes WebDAV folder

```

## Security Notes

- Electron runs with `contextIsolation: true`
- `nodeIntegration` is disabled in renderer windows
- Network requests that need desktop privileges are routed through Electron IPC instead of renderer-side browser fetch

Current limitation:

- Login credentials are still persisted in `localStorage`

That is convenient for development, but it is not the right long-term storage mechanism for a production desktop app. A future improvement should move credentials into the OS keychain or another secure secret store.

## Packaging

Electron packaging is set up with `electron-builder`.

Current packaging commands:

- `npm run dist:dir` creates an unpacked app bundle in `release/`
- `npm run dist:mac` creates macOS `.dmg` and `.zip` artifacts in `release/`
- `npm run dist:win` creates Windows `.exe` and `.zip` artifacts for the current Windows architecture
- `npm run dist:win:arm64` creates Windows ARM64 `.exe` and `.zip` artifacts in `release/`

The current mac build is unsigned and not notarized, which is fine for local use and testing but not enough for friction-free public distribution through Gatekeeper.

Windows ARM64 packaging has been validated in this repository with Electron Builder on Windows 11 ARM running under Parallels. Linux targets are still configured in `package.json`, but they have not been validated here yet.

## Legacy Tauri Script

There is still a `npm run tauri` script in `package.json`, but the README and current workflow are centered on Electron.
