What is the minimum knowledge of node.js to create a chat bot (in viber)?

Question

Node.js

There was a need to write a chat bot, and it was in viber. Among all the technologies on which you can write it, node.js is more suitable for me, since I am more or less familiar with the basics of JS.
The essence of the question is: what is the minimum knowledge of node.js that you need to know in order to write at least a simple application at the level: I write "ping", I get "pong" in response. That is, I don’t need a node here to write the server side of the site and other things. I don't want to splurge on aspects of node that I won't need for my chatbot, for a chatbot of my level of complexity.
PS. If the following information is important to someone, then I will announce: someday I will most likely study node thoroughly, but so far such a task is not worth it.

Answer 1

The minimum for you is to reach the goal. Sit down to study the documentation of the bot, write the bot, then what will stop it is what you are missing. Of course your question is strange.
