    The question is not specific. If the task comes down to, for example, arranging a chat for two users on a web page, then there are many approaches for its implementation.

    For example :

    • HTML5 + JavaScript client code with web-based communication,
    • server code on Node.js.

      NodeJS + Redis I would advise you.
