🔨 Telegram private channels mediafiles scraper bot

⚙️ How it works?

Initiate the userbot:

import { TelegramClient } from 'telegram';
import { StoreSession } from 'telegram/sessions';

async function main() {
  const client = await initClient();
}

async function initClient() {
  const storeSession = new StoreSession('userbot-session');

  const client = new TelegramClient(
    storeSession,
    USERBOT_API_ID,
    USERBOT_API_HASH,
    {
      connectionRetries: 5,
    }
  );

  await client.start({
    phoneNumber: USERBOT_PHONE_NUMBER,
    password: async () => await input.text('Please enter your password: '),
    phoneCode: async () => await input.text('Please enter the code you received: '),
    onError: (err) => console.log('error: ', err),
  });
  console.log('You should now be connected.');
  console.log(client.session.save()); // Save the session to avoid logging in again
  await client.sendMessage('me', { message: 'Hi!' });

  return client;
}

• Get private message data by its link:

const msgLink = 'https://t.me/c/1234/5678'.split('/');
const channelId = msgLink.at(-2);
const postId = msgLink.at(-1);

const channelEntity = await client.getEntity(channelId);

const privateMsgData = await client.invoke(
  new Api.channels.GetMessages({
    channel: channelEntity,
    id: [postId],
  })
);

• Download all private message mediafiles:

for (const msgData of privateMsgData.messages) {
  if (msgData.media) {
    const mediaType = 'photo' in msgData.media ? 'photo' : 'video';
    const fileName = mediaType === 'photo' ? 'photo.jpg' : 'video.mp4';

    const buffer = await client.downloadMedia(msgData.media);
    if (buffer) {
      client.sendFile('me', {
        file: buffer,
        attributes: [new Api.DocumentAttributeFilename({ fileName })],
        caption: msgData.message,
      });
    }
  }
}
