# Public Google Calendar Integration - Vue Event calendar demo

Load events from a public Google Calendar into a Vue event calendar using the integration plugin — provide your Calendar ID and API key. For Vue and Nuxt.

## Description

Event data can be loaded from remote sources, like public google calendars. Through the [**integration plugin**](https://mobiscroll.com/docs/vue/eventcalendar/calendar-integrations) you can easily show events that are available in a public calendar. The integration plugin needs to be added to the download package or installed separately from a dedicated NPM package.

You will just need the `CALENDAR_ID` and an `apiKey` from google and you should be ready to roll.

Public calendars are read-only. If you are interested in syncing private google calendars with read/write/delete access, [check out this example](https://demo.mobiscroll.com/vue/eventcalendar/sync-events-google-calendar).

This example uses the [**integration plugin**](https://mobiscroll.com/docs/vue/eventcalendar/calendar-integrations) to connect to and load events from Google Calendar and it is not available in the trial. Give the live demo a try and see how it can be configured.

## What this demo shows

- A desktop month-view event calendar with event labels loaded from public Google Calendars.
- **Custom header** The current month and year are shown on the left side of the header.
- **View switching** A segmented control in the center lets users switch between `Month`, `Week`, `Day`, and `Agenda` views, with `Month` selected by default.
- **Secondary navigation** Blue previous and next arrow buttons are shown on the right side of the header with a `Today` button between them.
- **Month view** Days with events display event labels inside the month grid cells.
- **Event selection** Hovering over or clicking an event label highlights the selected event.
- **Day cell states** Hovering a day cell highlights the day number with a gray background, while clicking the empty part of the cell selects the day and highlights the day number with a blue background.
- **Swipe navigation** The calendar supports changing months by clicking and dragging the view left or right.
- **Weekly scheduler view** Selecting the `Week` option from the segmented control switches the layout to a weekly scheduler view. This shows the days of the week at the top, an all-day section for all-day events, and a 24-hour time grid for each day of the week for timed events.
- **Daily scheduler view** Selecting the `Day` option from the segmented control switches the layout to a daily scheduler view. This shows the days of the week at the top, an all-day section for all-day events, and a 24-hour time grid for one day for timed events.
- **Scheduler view** The current time is marked with a blue line in the time grid.
- **Scheduler view** The time grid can be scrolled vertically with the mouse wheel while the header stays sticky.
- **Weekly agenda view** Selecting the `Agenda` option from the segmented control switches the layout to a weekly agenda view. This shows the days of the week at the top, and below the events listed in weekly agenda.

## Best for

- **Google Calendar overlays** Showing events from public Google Calendars inside a Mobiscroll month-view calendar.
- **Read-only event publishing** Sharing team, organization, or community calendars where visitors need to browse events but not edit them.

## Implementation notes

- Import `googleCalendarSync` from `@mobiscroll/calendar-integration` (a separately installed package). Define a single `CALENDAR_ID` constant - one public Google Calendar. No user sign-in required; access is via API key only. Set `exclusiveEndDates: true`. The calendar is read-only (no `clickToCreate`/`dragToCreate`).
- Default view: `calendar: { labels: true }`. A `SegmentedGroup` view switcher in the header lets the user pick between four views:
  - `'month'` → `{ calendar: { labels: true } }`
  - `'week'` → `{ scheduler: { type: 'week' } }`
  - `'day'` → `{ scheduler: { type: 'day' } }`
  - `'agenda'` → `{ calendar: { type: 'week' }, agenda: { type: 'week' } }`
- Call `googleCalendarSync.init({ apiKey, onInit: loadEvents })` on mount. `onInit` fires when the integration is ready.
- **`loadEvents`**: calls `googleCalendarSync.getEvents(CALENDAR_ID, firstDay.current, lastDay.current)` and replaces the events array on success.
- **`onPageLoading`**: sets date refs and calls `loadEvents()`. For `'month'` view use `args.viewStart`/`args.viewEnd` directly. For all other views, pre-load ±7 days: `firstDay = start − 7 days`, `lastDay = end + 7 days`.
- **Custom header** (`renderHeader`, Angular: `headerTemplate`, Vue: `#header` slot): `CalendarNav` (left), spinner (visible while loading), `SegmentedGroup` (Month/Week/Day/Agenda), then `CalendarPrev`, `CalendarToday`, `CalendarNext` (right).
