This is a simple bot that returns your Telegram Chat ID when you send a message to the bot.

It is also a simple proof of concept to deploy serverless Telegram Bot to Vercel's Now.

For local development polling mechaninsm is used to get Telegram messages.

1. Create .env file with your TELEGRAM_TOKEN. (TIP: Make sure to create a development bot, so you don't override production)

2. Install dependencies with npm i

3. Run with npm start or npm run dev for watching (nodemon is required, if you don't have it installed simple npm i -g nodemon)

4. Talk to your bot

Once you have a Vercel account and Vercel CLI installed, simple deploy with now command. (Make sure to have setted up TELEGRAM_TOKEN as Environment Variable).

During build phase, Vercel will run npm run now-build, which will execute build.js and configure Telegram Bot using webhook.
