A Cloudflare Worker that integrates with a Telegram Bot to filter spam and manage silence consensus polls.

1. Install dependencies:

   npm install

2. Configure your environment variables in wrangler.toml:

   [vars]
    TG_BOT_USERNAME = "your bot username"
    TG_SPAM_RE = "regular expression to detect spam message on username and text message"
    TG_ALLOWED_CHAT_USERNAMES = "allowed chat room to proceed"
    TG_SILENCE_CONSENSUS_COMMAND = "/silence"
    TG_SILENCE_CONSENSUS_MIN_COUNT = 3
    TG_SILENCE_CONSENSUS_POSITIVE_RATIO = 0.7
    TG_SILENCE_CONSENSUS_RESTRICT_DURATION = 259200
    TG_SILENCE_CONSENSUS_POLL_DURATION = 86400

3. Set up your secrets using Wrangler:

   npx wrangler secret put TG_BOT_TOKEN
   npx wrangler secret put TG_HOOK_SECRET

4. Set up D1 SQL

   create D1 database on cloudflare

   npx wrangler d1 create tg-bot-d1
   
   # paste the result to wrangler.toml

   create schema

   # local
   npx wrangler d1 execute tg-bot-d1 --local --file=./schema/schema.sql
   
   # remote
   npx wrangler d1 execute tg-bot-d1 --remote --file=./schema/schema.sql

To run the worker locally:

npm run dev

To deploy the worker to Cloudflare:

npm run deploy

This requires you to be logged in with wrangler login or have your API token configured in ~/.wrangler/config.toml.

1. Create a bot using BotFather (https://t.me/botfather) to get the token
2. The Bot ID is the username of your bot without the @ symbol
3. Hook Secret is a value you create to secure webhook endpoints (https://core.telegram.org/bots/api#setwebhook)
4. Spam Regex is a regular expression pattern used to identify spam messages
