-# @aris/source-caldav
-
-A FeedSource that fetches calendar events from any CalDAV server.
-
-## Usage
-
-```ts
-import { CalDavSource } from "@aris/source-caldav"
-
-// Basic auth (Nextcloud, Radicale, Baikal, iCloud, etc.)
-const source = new CalDavSource({
-	serverUrl: "https://caldav.example.com",
-	authMethod: "basic",
-	username: "user",
-	password: "pass",
-	lookAheadDays: 7, // optional, default: 0 (today only)
-	timeZone: "America/New_York", // optional, default: UTC
-})
-
-// OAuth
-const source = new CalDavSource({
-	serverUrl: "https://caldav.provider.com",
-	authMethod: "oauth",
-	accessToken: "...",
-	refreshToken: "...",
-	tokenUrl: "https://provider.com/oauth/token",
-})
-```
-
-### iCloud
-
-Use your Apple ID email as the username and an [app-specific password](https://support.apple.com/en-us/102654):
-
-```ts
-const source = new CalDavSource({
-	serverUrl: "https://caldav.icloud.com",
-	authMethod: "basic",
-	username: "you@icloud.com",
-	password: "<app-specific-password>",
-})
-```
-
-## Testing
-
-```bash
-bun test
-```
-
-### Live test
-
-`bun run test:live` connects to a real CalDAV server and prints all events to the console. It prompts for:
-
-- **CalDAV server URL** — e.g. `https://caldav.icloud.com`
-- **Username** — your account email
-- **Password** — your password (or app-specific password for iCloud)
-- **Look-ahead days** — how many days beyond today to fetch (default: 0)
-
-The script runs both `fetchContext` and `fetchItems`, printing the calendar context (in-progress events, next event, today's count) followed by each event with its title, time, location, signals, and attendees.
