# caldav-cli

A CalDAV CLI client. Manages multiple accounts with secure OS keychain storage. Supports iCloud, Google (OAuth2), Yandex and any custom CalDAV server.

## Installation

Requires Node.js >= 18.

```bash
npm install -g caldav-cli
```

After installation the `caldav-cli` command is available globally.

## Quick Start

```bash
caldav-cli account add          # Interactive wizard: pick provider, enter credentials
caldav-cli events list          # Show events for the next 7 days
caldav-cli events create        # Interactive wizard: create a new event
```

## Account Management

Add account (interactive wizard — prompts for provider, credentials, tests connection):
```bash
caldav-cli account add
```

List configured accounts:
```bash
caldav-cli account list
```

Remove an account:
```bash
caldav-cli account remove <name>
```

## View Events

```bash
caldav-cli events list                           # Next 7 days (default)
caldav-cli events list --from 2026-02-10 --to 2026-02-20
caldav-cli events list -a work                   # Specific account
caldav-cli events list -c "Team Calendar"        # Filter by calendar name
caldav-cli events list -a work -c Personal --from 2026-03-01 --to 2026-03-31
```

JSON output (for scripting):
```bash
caldav-cli events list --json
caldav-cli events list --json --from 2026-02-10 --to 2026-02-20
```

## Create Events

Interactive wizard (prompts for all fields):
```bash
caldav-cli events create
```

Non-interactive (all options via flags):
```bash
caldav-cli events create \
  --title "Team standup" \
  --start "2026-02-10T10:00" \
  --end "2026-02-10T10:30" \
  --account work \
  --calendar "Team Calendar" \
  --description "Daily sync" \
  --location "Room 42"
```

Partial flags (wizard prompts for the rest):
```bash
caldav-cli events create --title "Lunch" --account work
```

JSON output after creation:
```bash
caldav-cli events create --json --title "Event" --start "2026-02-10T10:00" --end "2026-02-10T11:00"
```

## Supported Providers

| Provider | Auth | Server URL |
|----------|------|------------|
| Apple iCloud | Basic (app-specific password) | `https://caldav.icloud.com` |
| Google Calendar | OAuth2 (Client ID + Secret) | `https://apidata.googleusercontent.com/caldav/v2` |
| Yandex Calendar | Basic (app password) | `https://caldav.yandex.ru` |
| Custom | Basic | User provides URL |

## Google Calendar Setup

Google requires OAuth2. Before running `caldav-cli account add`:

1. Go to https://console.cloud.google.com/
2. Create a project, enable CalDAV API
3. Create OAuth client ID (Desktop app type)
4. Note the Client ID and Client Secret

The wizard will ask for these, then open a browser for authorization. The refresh token is stored securely in the OS keychain.

## Data Storage

- **Passwords, OAuth2 refresh tokens, and OAuth2 client credentials** (Client ID, Client Secret, Token URL): OS keychain (macOS Keychain, Linux libsecret, Windows Credential Vault) via `@napi-rs/keyring`. Never written to disk in plaintext.
- **Account metadata** (name, provider ID, username, server URL): `~/.config/caldav-cli/config.json` (file permissions `0600`).

No secrets are stored on disk. Existing installations that stored OAuth2 client credentials in `config.json` are automatically migrated to the keychain on first run.
