How to set up a Telegram Proxy (MTProxy)

This tutorial will teach you how to set up a Telegram MTProxy on an Ubuntu 22.04 sever using AWS Lightsail, although you can use any other Linux distribution and cloud provider.

Using a Telegram proxy is a safe, easy and effective way of overcoming Telegram bans. It's useful, for example, to keep using Telegram under tyrannical regimes, or to circumvent judges' decisions to block Telegram.

Telegram proxies are a built-in feature in all Telegram apps (both mobile and desktop). It allows Telegram users to connect to a proxy in just one or two clicks / taps.

Telegram proxies are safe: Telegram sends messages using their own MTProto secure protocol, and the proxy can only see encrypted traffic – there's no way for a proxy to decrypt the traffic and read the messages. The proxy does not even know which Telegram users are using the proxy, all the proxy sees is just a list of IPs.

// Usage:
//   node --import=./typescript-hook.js --watch ./dist/index.js
//
// Make changes to your TypeScript code, have it automatically
// recompiled, and see it reloaded in Node.js.
//
// This file is intended to be used as a Node.js preload module.
// The TypeScript compiler (tsc) will be run in watch mode.
// This is useful while running Node.js itself runs in watch mode.

This was originally written for a Remix app, but you could adapt it to work for any SSR framework.

It's configured to use MySQL on Planetscale, but you could adjust it to use Postgres or SQLite if you want.
