“How do you indent that you users interact with your app?’ The application is an Interactive Fiction Interpreter. All user input is text (keyboard) and so is the application’s output. When running locally, the application runs ins a CMD-window (windows) or a terminal window (linux and macos). So I think what I need is one web page with an input prompt and output on the same page. Sort of like a chat conversation: enter some text and get a reply.
