Setting Up Vanilla Calendar Pro

To start using Vanilla Calendar Pro, you can add it to your project either by installing it via npm or using a CDN link.

Option 1: Installing via npm

If you’re using npm, install Vanilla Calendar Pro with the following command:

npm install vanilla-calendar

Then, import it into your JavaScript file:

import VanillaCalendar from 'vanilla-calendar';

Option 2: Using the CDN

For a quick setup, you can include the Vanilla Calendar Pro library directly from the CDN in your HTML file:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vanilla-calendar@latest/dist/vanilla-calendar.min.css">
<script src="https://cdn.jsdelivr.net/npm/vanilla-calendar@latest/dist/vanilla-calendar.min.js"></script>

With Vanilla Calendar Pro installed, you’re ready to initialize your first calendar.

Creating a Basic Calendar

To create a basic calendar, add an HTML container where the calendar will appear. Then, initialize the Vanilla Calendar instance in your JavaScript code.

<div id="calendar"></div>

<script>
  // Initialize the calendar
  const calendar = new VanillaCalendar("#calendar");
  calendar.init();
</script>

This simple setup creates a basic interactive calendar in the specified container, ready for immediate use.

Customizing the Calendar

One of Vanilla Calendar Pro’s strengths is its customizability. You can modify its appearance, add event handlers, and tailor its functionality to match your application’s requirements.

Customizing the Appearance

You can adjust the calendar’s appearance by passing configuration options when initializing the calendar. For example, to change the starting week day and highlight today’s date, use:

const calendar = new VanillaCalendar("#calendar", {
  settings: {
    iso8601: true, // Week starts on Monday
    highlightToday: true, // Highlight the current date
  }
});
calendar.init();

You can also apply custom CSS styles to control the calendar’s color scheme and layout further. Vanilla Calendar Pro’s CSS classes make it easy to personalize the design to match your website’s theme.

Adding Events

Vanilla Calendar Pro allows you to add events, making it an excellent choice for applications that require scheduling or reminders. You can pass an array of event objects during initialization or add them dynamically.

const events = [
  { date: "2023-12-25", title: "Christmas Day" },
  { date: "2023-12-31", title: "New Year's Eve" }
];

const calendar = new VanillaCalendar("#calendar", {
  settings: {
    iso8601: true,
  },
  actions: {
    clickDay: (event, date) => {
      alert(`Date clicked: ${date}`);
    }
  },
  events
});
calendar.init();

This example shows how to set up events and trigger an alert when a specific date is clicked, making it easy to interact with calendar dates and respond to user selections.

Event Handling

The clickDay action allows you to add custom event handlers, making Vanilla Calendar Pro highly interactive. Here’s how to set up an event handler that triggers when a date is clicked:

const calendar = new VanillaCalendar("#calendar", {
  actions: {
    clickDay: (e, date) => {
      console.log("Selected date:", date);
      // Additional logic here
    }
  }
});
calendar.init();

This action logs the selected date to the console. You could extend it to open a modal, show more details, or initiate another function based on the clicked date.

Advanced Features

Range Selection

If you need users to select a range of dates, Vanilla Calendar Pro supports range selection. This feature is perfect for booking or multi-day event management:

const calendar = new VanillaCalendar("#calendar", {
  settings: {
    selection: {
      type: "range", // Enable range selection
    }
  }
});
calendar.init();

Range selection allows users to click and drag to select multiple dates, ideal for vacation booking or multi-day event planning.

Date Restrictions

To limit date selection, you can disable specific dates or set min/max date ranges. For instance, to disable past dates and limit selection to the next month:

const calendar = new VanillaCalendar("#calendar", {
  settings: {
    minDate: "2023-12-01",
    maxDate: "2023-12-31",
  }
});
calendar.init();

This feature is particularly useful for preventing users from choosing dates outside a valid range, like past dates for a booking system.

Multi-View Calendars

Vanilla Calendar Pro also supports multi-view layouts, displaying multiple months simultaneously. This is useful for applications that require a broader date view, such as vacation planners or project schedules:

const calendar = new VanillaCalendar("#calendar", {
  settings: {
    visibility: {
      months: 2 // Show two months at a time
    }
  }
});
calendar.init();
