Before you get start make sure you already have a telegram bot

How to create a telegram bot

1. Access BotFather: Open the Telegram app and search for "@BotFather"
2. Start a conversation: Click "Start" to begin interacting with BotFather.
3. Create a new bot: Send the command "/newbot".
4. Provide details: Enter a name for your bot and a unique username that must end with "bot".
5. Receive your token: Once created, BotFather will provide you with your bot's access token, which is necessary to interact with your bot using code.

Get started

Installation

Using npm:

$ npm install gl.telegram-bot

Creating instance of bot

You can use this bot instance to call its bot actions

import TelegramBot from "gl.telegram-bot";

const botInstance = new TelegramBot('1234567:ASJHR24-93145uASJHF-ASDIRFJ3158');

Bot Actions

sendMessage

tip: to get channel the channel id you can enter the following url on your browser
https://api.telegram.org/bot$BOT_TOKEN/getUpdates \

if your token is something like this: 123456-78910
you should add bot as prefix and the ouput should be like this: bot123456-78910

This action sends a message to an individual group

// send to 1 group id
botInstance.sendMessage('test message', '-100123456789');

// send to multiple groups
botInstance.sendMessage('test message', ['-100123456789', '-100987654321']);

getUpdates

@return_type - object;
It gets the recent updates on your bot

const updates = await botInstance.getUpdates();

// this is 
console.log(updates);

getGroupIDs

@return_type - number[];
Basically, it uses getUpdates and then get all its channel id's

const groupIDs = await botInstance.getGroupIDs();

// this is 
console.log(updates);
