node-telegram-bot-api

Why we included this project

node-telegram-bot-api handles the boring parts of running a Telegram bot from JavaScript or TypeScript: long-polling, webhooks, retries, and update parsing are already done, so you can focus on commands and replies. It wraps the official Bot API in a typed client that mirrors the wire protocol one method per endpoint, and a koa-style middleware chain gives you a predictable place to handle commands, regex triggers, messages, and callback queries. The inline keyboard and entity builders spare you the fiddly reply_markup and UTF-16 offset math that trips up new bot writers. The v2 rewrite runs on Node, Bun, Deno, Cloudflare Workers, and Vercel Functions without changes, and streaming file uploads keep memory flat for large media. That makes it a solid choice if you want one codebase that works across runtimes and don't want to lock yourself into a single deployment target.
