  $ sudo apt install nodejs $ sudo apt install npm

Configure bot

Edit the config.json file with your settings. Use the files in the examples folder as a reference, and check the examples README to know about all configurations. See models.ts for a detailed explanation of every configuration.

Edit the .env file in the root folder by changing the BOT_TOKEN string to connect your Telegram account:

• The BOT_TOKEN is provided by https://t.me/botfather, more info here: https://core.telegram.org/bots/api
• The CHAT_ID is provided after starting a chat with the Telegram bot. It will be saved automatically in the .env file.

If you enable the purchase mode, add those strings in the .env file with your account credentials:

PCC_USER=username@mail.com
PCC_PASS=userpassword

Running the project

$ yarn start

To run it on a Raspberry (maybe chmod + x is needed), you can also execute: run_raspberry.sh

Warnings about the purchase

Cart management

If purchase mode is activated, the bot will add the article into the cart and try to order everything in it. Please keep it empty!

Payment methods

The transfer option disappears from time to time. If purchase mode is activated, you will need to have a vinculated card.

To vinculate one, follow those steps:

• Add whatever in the cart and start the purchase process.
• Add your credit / debit card, then confirm the purchase. This vinculates the card.
• If you don't need the article you can cancel the purchase here. The card will remain in your account for future usage.

Known issues

Login fails, but credentials are right

Edit the puppeteer-config.json and set "debug":true. Restart the bot, and in the login attempt check if a captcha appears. Solve it manually after the bot introduces the credentials, and perform a login. Then set "debug":false again and check it the problem is solved.
