Steps

1. To start work with telegram you have to get telegram token from @BotFather. Write to BotFather /newbot, write display name of your new bot, then username and you should get telegram token.

2. Then open my-app directory which you have install via create-urban-bot and paste the telegram token to .env file.

3. After this open src/index.ts or src/index.js and uncomment // import './render/telegram';

   src/index

   

4. Your bot is ready to launch! Run npm run dev in my-app directory and write something to your bot. It should work as default app with two commands /echo and /logo.

If you see error looks like error: [polling_error] {"code":"EFATAL","message":"EFATAL: Error: connect ECONNREFUSED 127.0.0.1:9150"} probably an internet provider blocks Telegram connection. You need to use a VPN, or you could use the Tor browser, see the example.
