Three new menu entries exercise the MarkdownV2 truncation path that the prior commit fixed: - Long (5000 plain) — basic truncation, verifies escaped `\.\.\.` ellipsis - Long (bold crosses 4096) — entity-balancing heuristic for unclosed `*` - Long (code crosses 4096) — entity-balancing heuristic for unclosed `` ` `` Each button posts a message whose rendered length exceeds Telegram's 4096-char limit and would have produced `can't parse entities` 400s against the previous truncator. Serves as an interactive smoke test alongside the unit tests in packages/adapter-telegram.
telegram-chat
A Telegram bot that exercises the Chat SDK end-to-end: MarkdownV2 rendering, cards with inline-keyboard actions, reactions, file uploads, and streaming edits. Runs in polling mode — no webhook, no public URL, no deploy.
Doubles as a reference example for developers learning the SDK and an interactive smoke-test harness for the @chat-adapter/telegram package.
Prerequisites
- Node.js ≥ 20
- A Telegram bot token from @BotFather
Run
From the repo root:
pnpm install
TELEGRAM_BOT_TOKEN=<your_token> pnpm --filter example-telegram-chat start
Optional: TELEGRAM_BOT_USERNAME=<handle> (defaults to telegramchatdemobot).
Then DM the bot — any message opens the main menu.
What you see
The bot replies with an inline keyboard with three categories:
- Text & Markdown — 6 curated markdown demos plus a streaming edit loop
- Cards & Actions — interactive approval card, callback-data size probe, link buttons
- Media & Reactions — on-demand reactions, generated PNG and PDF uploads
Every sub-menu has a ← Back button. Sending any text at any time reopens the main menu.
Why it's stateless
No thread subscription, no persistence. Every button press is self-contained; memory state is used only because the SDK requires a state adapter. If you need a stateful reference, see examples/nextjs-chat.
