### Basic Telegraf Bot Example

Source: https://telegraf.js.org/index.html

A fundamental example demonstrating how to create a Telegraf bot, handle basic commands like start and help, and respond to messages and stickers. It includes setup for graceful shutdown.

```javascript
const { Telegraf } = require('telegraf')
const { message } = require('telegraf/filters')

const bot = new Telegraf(process.env.BOT_TOKEN)
bot.start((ctx) => ctx.reply('Welcome'))
bot.help((ctx) => ctx.reply('Send me a sticker'))
bot.on(message('sticker'), (ctx) => ctx.reply('👍'))
bot.hears('hi', (ctx) => ctx.reply('Hey there'))
bot.launch()

// Enable graceful stop
process.once('SIGINT', () => bot.stop('SIGINT'))
process.once('SIGTERM', () => bot.stop('SIGTERM'))
```

--------------------------------

### Install Telegraf using npm

Source: https://telegraf.js.org/index.html

### Start Webhook via launch Method

Source: https://telegraf.js.org/index.html

Launches the Telegraf bot using the launch method with webhook configuration. This is the preferred method for starting a webhook server. Ensure you provide the webhook domain, port, and optionally a path and secret token for security.

```javascript
import { Telegraf } from "telegraf";
import { message } from 'telegraf/filters';

const bot = new Telegraf(token);

bot.on(message("text"), ctx => ctx.reply("Hello"));

// Start webhook via launch method (preferred)
bot.launch({
  webhook: {
    // Public domain for webhook; e.g.: example.com
    domain: webhookDomain,

    // Port to listen on; e.g.: 8080
    port: port,

    // Optional path to listen for.
    // `bot.secretPathComponent()` will be used by default
    path: webhookPath,

    // Optional secret to be sent back in a header for security.
    // e.g.: `crypto.randomBytes(64).toString("hex")`
    secretToken: randomAlphaNumericString,
  },
});
```

--------------------------------

import { message } from 'telegraf/filters';

const bot = new Telegraf(process.env.BOT_TOKEN);

bot.use(async (ctx, next) => {
  console.time(`Processing update ${ctx.update.update_id}`);
  await next() // runs next middleware
  // runs after next middleware finishes
  console.timeEnd(`Processing update ${ctx.update.update_id}`);
})

bot.on(message('text'), (ctx) => ctx.reply('Hello World'));
