<pre>
import React, { Component } from "react";
import { render } from "react-dom";
import Home from "./components/Home.jsx";

const TelegramBot = require('node-telegram-bot-api');
const token = "MY_TOKEN";
const bot = new TelegramBot(token, {polling: true});

render(Home, document.getElementById("root"));

Answer 1

You can't use require in a browser application (like react). require is for node.js apps, only do import .

This telegram bot seems to require access to the filesystem ( fs ) and that is not available in the browser anyway, so you won't be able to use it directly in the frontend.

Sorry for the bad news.
