Telegram Welcome Bot

Simple Telegram bot that sends a welcome message to new members.

Note: not actively maintained, but will accept PRs and review small bugs.

Features

• Welcomes new members to a group.
• Welcome message can be changed with the /change_welcome_message command.
• Filesystem persistence for restart resilience.
• Dead-easy deployment and setup.

Installation

You need NodeJS v8+ installed on your server to deploy and run this bot.

1. Clone this repo on a server.
2. Execute npm i on the repo directory.
3. Create a bot through the @BotFather bot to obtain both a bot api token and a bot username (@example_bot).
4. Execute npm run start -- --persistence-path <filesystem path for persistence> --api-token <your bot's token> --bot-username <your bot's username>.

Command line options have the following short forms:

• --persistence-path: -p (default path is <repo directory>/.persistence)
• --api-token: -t
• --bot-username: -u

Command list

For autocompletion and command list within the Telegram apps, you might want to configure the command list through BotFather.

For your convenience, here's a copy-paste list of the commands, correctly formatted:

change_welcome_message - Changes the welcome message of the group
help - Displays a help message

Deployment example

$ npm run start -- -p ~/bot -t 582659278:JsjjSHDNns-JjshJhann2nhJjans88kKSiw -u welcome_message_bot

Enjoy!
