telegraf VS Express

Simply use telegraf : https://telegraf.js.org/

this is pretty simple , you can create a bot yourself which simply listens for every message checks length and if exceeded deletes the message (bot must be added as admin ingroup and shows have read permission in bot settings) , I would suggest you to use https://github.com/telegraf/telegraf for the code,

In this project we will use the Telegraf library to create the bot. To install it, you can use the npm install command.

Changed the main library for working with telegram from https://telegraf.js.org to https://grammy.dev, updated the source code for better work with typings

Of course, it's good to write API requests yourself. It reduces the dependency on third-party libraries and allows you to control the behavior of the code more. But when there are more such methods than twenty, it already increases the size of the code. It becomes difficult to manage all the logic. This is where third-party libraries(frameworks) come to the rescue. After choosing a language, you can consider the options of different libraries from the list here, on the official Telegram page. For JavaScript I recommend using node-telegram-bot-api and telegraf. For Python you can take pyTelegramBotAPI and aiogram(highly recommended).

It’s an expressive type system, but ime it allows developers to go crazy on type interdependencies and general entanglement, so you can’t just go to the “header” and quickly figure out what your method or a return value really is, despite TS has structural typing.

E.g. look at this: https://github.com/telegraf/telegraf/blob/v4/src/telegram-ty...

The bot uses telegraf framework, which is an overlay for the original telegram api, which is a nightmare in code form.

Honestly I found their API one of the worst ones I've ever used. The documentation is lacking, and they have some unintuitive quirks like posting messages with http GET requests and randomly concatenating strings in params (botNAMEOFBOT anyone?).

I didn't enjoy using it without a third party library [1].

Sending a single message is easy, but using the rest of telegram's features is "meh" when using pure API calls.

If you want to see a well designed API, you should take a look at FTX or Stripe. I love those two :)

Today the most popular ways to build telegram chat bots in node js are Telegraf and Node-Telegram-Bot-Api. The second is more popular by weekly downloads(250.000), but in this post I don't want to equalize them by stats. I want to talk about my experience with them, in which cases I used them and show you really nice guide, especially for Telegraf, cause they haven't readable docs for newbies or people who don't use typescript.

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Basic Knowledge of Express

Express.js Documentation

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.

express - one of the most popular middleware tools, lightweight and easy to learn. docs

Now we can install both Express and Socket.io libraries:

app.listen(3000); ``` Now you can run your server by executing `node index.js`. Your web application will be accessible at http://localhost:3000/, where you'll see "Hello, world!" displayed in your browser. Congratulations! 🎉 You've successfully set up basic routing with Express.js! This guide covered only the tip of the iceberg when it comes to utilizing Express.js features. Explore its extensive documentation (https://expressjs.com/) to discover more possibilities. Remember, with Express.js, you have the power to build efficient and scalable web applications. Happy coding!

Converting a large Express.js application from JavaScript to TypeScript can be a challenging task. For many applications, this represents a significant portion of their technical debt, as the process may span many days, if not months, and new changes are typically not allowed during the conversion.

Nitro is a nice https webserver that you can deploy everywhere. Comparing it to express, it doesn't need weird middlewares for json, it has a simple way to support caching, a file system router, tasks and scheduled tasks that avoid quite a few shell scripts, db:migrations etc, plugins, KV storages, SQL connectors, websockets...
