error-shout-bot

Installation & Configuration

error-shout-bot is available as a npm package

npm install error-shout-bot --save

Import the library and intialise it

var ErrorShout = require('error-shout-bot');
var Shout = new ErrorShout(botToken, chatId);

botToken is a string that is unique to your bot. New bots and bot tokens can be requested from the Telegram BotFather.

chatId is a string representing where you want the messages to get posted. There are 3 options for this:

1. Individual user's chatId - e.g. "123456789" - Find out you own by starting a chat with IDBot. NOTE: You need to start a conversation with your bot before it can message you
2. Group's chatId - e.g. "-123456789" - Find out a groups chat Id by adding IDBot to the group. NOTE: Your bot needs to be added to the group before it can post in it.
3. Channels - e.g "@ErrorChannelName" - NOTE: Your bot needs to be admin of a channel to post in it.
