telegraf-calendar-telegram

Inline calendar for Telegram bots using Telegraf framework. You can contact @CalendarTelegrafBot to test the calendar.

Description

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

Usage

Installation

npm i telegraf-calendar-telegram --save

or

yarn add telegraf-calendar-telegram

Basic usage

// 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.

Customization

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,
	ignoreWeekDays: [],
	shortcutButtons: [],
	hideIgnoredWeeks: false
}

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)
• ignoreWeekDays: numbers of week days that can't be selected by user (E.g. when startWeekDay is 1, 5 means saturday and 6 means sunday)
• shortcutButtons: list of additional buttons data, which will be displayed at the top of calendar. You can add a button with: shortcutButtons: [{"label": "Today", "action": "ping"}] and you can handle it with bot.action("ping", context => context.reply("pong"))
• hideIgnoredWeeks: hide a week if all days of a week can't be selected
