# TelegramBotAPI examples

Runnable examples for [TelegramBotAPI](https://github.com/InsanusMokrassar/TelegramBotAPI). Each module focuses on a small Telegram Bot API feature and has its own README with detailed behavior, setup, permissions, and optional arguments.

## Running an example

Run commands from the repository root and replace placeholders such as `<BOT_TOKEN>` and `<ADMIN_USER_ID>`. The table uses JVM launchers for multiplatform modules; their module READMEs also document browser and native targets where available.

The shortcuts include all mode tokens supported by each launcher. Remove `debug` to disable verbose logging and remove `testServer` to use Telegram's production Bot API. These are positional values inside `--args` and intentionally have no leading dashes: the current launchers recognize `debug`, not `--debug`, and `testServer`, not `--testServer`.

Native targets on Linux require libcurl development files, for example:

```bash
sudo apt install libcurl4-gnutls-dev
```
