@telegraf/client
Low-level library for performing Telegram Bot API calls.
Provides StreamFile for uploading arbitrary streams. Other objects with
compatible interface (such as File provided by fetch-blob, undici, or
formdata-node) should work as well.
const { File } = require("formdata-node");
const { Client } = require("@telegraf/client");
const document = new File(["42"], "answer.txt");
const client = new Client(process.env.BOT_TOKEN);
await client.call("sendDocument", { chat_id, document });
