How to test a Telegram bot written in NodeJS?

Question

JavaScript

I am writing a bot in NodeJS. I uploaded it to Heroku, but either the server lags, or I wrote the code badly - the bot is dumb with answers and does not always respond, and after deploying a new version of the solution, the bot seems to work for 5 seconds, then groans.
How to test/debug a bot in some "emulator"?

Answer 1

JetBrains WebStorm, run the bot there in the console, and use it in telegram while WebStorm is running. Is Worker included in Heroku?

Answer 2

I recommend ngrok for pushing https to your localhost where the bot is running locally - it's very convenient to debug. If you go even further, then get yourself a separate bot for testing, in a dev environment, the server clings to this bot, and when you deploy it to production, then to the real one.
