General Pub/Sub Telegram Bot

What is the idea here: a simple bot for telegram. It allows you to send notifications via http and their a brodcast to whoever subscribes a channel.

Users should login 1st, so the bot will not send data to strangers

How it works:

• Bot will persist sessions and subscriptions on postgres database.
• An APIKey is set when setting up the service
• Http request should be sent w X-API-KEY header set, see below.
• Users call bot
• User call /login where is the password
• User can call:
  • /sub to subscribe a channel
  • /unsub to unsubscribe
  • /mysubs to list user own subscriptions
  • /subbers to list all users subscribing a channel
  • /pub will send a message to a channel

In case http requests are received as shown below, they will be forwarded to telegram users

Env

These vars are required to run the service:

• TBOTKEY: Telegram API Key for the bot
• DSN postgres database dsn, compatible with pg and gorm
• APIKEY: This is the apikey http clients should use when sending a notification
• USERPASS: Password users should give to bot when starting to comunicate

Please refer to: Telegram Bot Notify

for a simple notification lib to be used as companion to this bot.
