Registering records maker

Setting up dev environment for Telegram bots development

Tunneling to local development environment

To expose local server to the Internet we use ngrok.

ngrok http 4300

Make sure that you have started local GAE server & Firestore emulators - follow instructions from README.md.

After ngrok started you will see something like:

Forwarding    https://****-***-**.ngrok-free.app -> http://localhost:4300

You would need to register the forwarding URL for bot you are testing with Telegram by calling this url:

https://****-***-**.ngrok-free.app/bot/tg/set-webhook?code=BOT_CODE

where ****-***-** is the forwarding URL from ngrok output and BOT_CODE is the code of the bot you are testing.

The bot will be registered using secret tokens that you should set using environment variables:

TELEGRAM_BOT_TOKEN_<BOT_CODE>=<TELEGRAM_BOT_TOKEN>

You can create a personal bot for testing purposes using BotFather.

The bot with the given code should be registered in your app and the value is CASE SENSITIVE.
