Inline calendar for Telegram bots using Telegraf framework. You can test it using this bot.

Using this simple inline calendar you can allow your Telegram bot to ask dates. This library is built using Telegraf Framework.

npm i telegraf-calendar-telegram --save

// create the bot
const bot = new Telegraf(process.env.CALENDAR_BOT_TOKEN);
// instantiate the calendar
const calendar = new Calendar(bot);

// listen for the selected date event
calendar.setDateListener((context, date) => context.reply(date));
// retreive the calendar HTML
bot.command("calendar", context => context.reply("Here you are", calendar.getCalendar()));

This creates a calendar with the default options: you will have an english calendar with Sunday as starting week day.

When you instantiate the calendar, you can pass an option object:

const calendar = new Calendar(bot, {
	startWeekDay: 1,
	weekDayNames: ["L", "M", "M", "G", "V", "S", "D"],
	monthNames: [
		"Gen", "Feb", "Mar", "Apr", "Mag", "Giu",
		"Lug", "Ago", "Set", "Ott", "Nov", "Dic"
	]
});

This creates an italian calendar.

Default options:

{
	startWeekDay: 0,
	weekDayNames: ["S", "M", "T", "W", "T", "F", "S"],
	monthNames: [
		"Jan", "Feb", "Mar", "Apr", "May", "Jun",
		"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
	],
	minDate: null,
	maxDate: null
}

The options object has the following properties:

• startWeekDay: first day of the week, where 0 is Sunday
• weekDayNames: week day names, where the first element is startWeekDay name
• monthNames: month names
• minDate: minimum selectable date (there is a setter on Calendar object, too)
• maxDate: maximum selectable date (there is a setter on Calendar object, too)
