Is it possible to implement an RPG chat system in HTML5?

Hello.

Web building with Node.js environment.

I'm going to implement a chat system, and the chatting method used in RPG games such as the Kingdom of the Wind is

I want to implement it.

The following features are required:

The setInterval() method was used to represent the moving character here.

If so, it will be redrawn, so the sentence you chatted with will also be erased and will not be displayed.

I tried to draw the character as canvas and use socket.io to implement the chat.

Is there a separate way to implement it, or please give us tips or directions.

Thank you.
