Usage

Creating an Instance of TgNotifier

To use the TgNotifier library, you first need to create an instance of the TgNotifier class. You can configure it with your bot token, default chat ID, and other optional settings.

import { TgNotifier } from 'tg-notifier';

const notifier = new TgNotifier({
  token: 'YOUR_BOT_TOKEN',
  chatId: 'YOUR_CHAT_ID', // Optional: Default chat ID to use if not specified in the sendMessage method
  logsDir: 'path/to/logs', // Optional: Directory for logs
  cleanIntervalHours: 24, // Optional: Interval in hours for cleaning old logs (default is 24 hours)
  chatIdsFile: 'chat_ids.txt' // Optional: File to store chat IDs
});

Sending a Message

To send a message using the TgNotifier library, you have two main methods: sendMessage for sending to a specific chat and sendToMultipleChats for sending to multiple chats.

Sending a Message to a Single Chat

Use the sendMessage method to send an HTML-formatted message to a specific chat. Provide the message content and the chat ID as parameters.

await notifier.sendMessage('<b>Bold text</b> and <i>italic text</i>', 'CHAT_ID');

Sending a Message to Multiple Chats

If you want to send a message to multiple chats at once, use the sendToMultipleChats method. Provide the message and an array of chat IDs.

const chatIds = ['CHAT_ID_1', 'CHAT_ID_2'];
await notifier.sendToMultipleChats('<b>Bold text</b> and <i>italic text</i>', chatIds);
