node-telegram-bot-api follows a simple and straightforward architecture, allowing developers to quickly set up bots using either polling or webhook methods. It provides a clear and easy-to-understand API for handling messages, commands, and events.

telegraf is built around a middleware architecture, allowing developers to create more complex and scalable bots. This design enables the use of multiple middleware functions to handle different types of events, making it more flexible and powerful for building feature-rich bots.

node-telegram-bot-api does not have built-in middleware support, but developers can implement their own middleware-like functionality by creating custom handlers for different types of messages and events.

telegraf has first-class middleware support, allowing developers to easily create and use middleware functions to process messages, commands, and other events. This feature makes it easier to organize code and add reusable functionality.

node-telegram-bot-api supports inline queries, but developers need to implement the handling logic manually. The library provides the necessary methods to send inline query results, but it does not offer any built-in abstractions for managing inline queries.

telegraf provides built-in support for inline queries, making it easier to handle them with less boilerplate code. It offers a more structured way to manage inline queries and send responses, which can simplify the implementation.

node-telegram-bot-api supports file uploads, including photos, videos, documents, and more. Developers can easily send and receive files using the provided methods, and the library handles the necessary API calls.

telegraf also supports file uploads, with additional features for handling files more efficiently. It provides a more modern API for working with file uploads, making it easier to integrate into bots.

node-telegram-bot-api has a large and active community, with plenty of documentation and examples available. It is a well-established library with a strong user base, making it easy to find support and resources.

telegraf also has a growing community and is known for its modern approach to bot development. It has a rich ecosystem of plugins and middleware, which can help developers extend the functionality of their bots.

Simple Bot Example with node-telegram-bot-api

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

bot.on('message', (msg) => {
  const chatId = msg.chat.id;
  bot.sendMessage(chatId, 'Hello, World!');
});

Simple Bot Example with telegraf

const { Telegraf } = require('telegraf');
const bot = new Telegraf('YOUR_TELEGRAM_BOT_TOKEN');

bot.on('text', (ctx) => {
  ctx.reply('Hello, World!');
});

bot.launch();
