botrelay

Reusable primitives for Cloudflare Workers that need to:

1. Forward content (an email, a notification, anything) to a Telegram chat or Discord channel via a bot.
2. Route replies from those channels back to the original source (typically an email address).

The crate provides:

• botrelay::telegram — a minimal Telegram Bot API client (sendMessage, setWebhook) and typed Update parsing for the webhook endpoint.
• botrelay::discord — a minimal Discord Bot API client (createMessage with components), Ed25519 interaction-signature verification (WebCrypto), and typed Interaction parsing including modal submissions.
• botrelay::reply — a small ReplyContext type (alias, original sender, subject) you store per forwarded message so the webhook handler can look it up and send a reply back through whatever channel the original content came from.

It doesn't own storage or the send-reply side — each consumer plugs in its own KV and outbound mechanism. That's the whole point: both cutout (email proxy) and concierge-worker (business messaging) embed the same primitives with different backends.

Usage

[dependencies]
botrelay = "0.1"

use botrelay::telegram::{TelegramBot, SendMessage};

let bot = TelegramBot::new(std::env::var("TELEGRAM_BOT_TOKEN").unwrap());
let msg = bot.send_message(SendMessage {
    chat_id: "123456".into(),
    text: "Hello!".into(),
    ..Default::default()
}).await?;
