Currently have a problem getting my code to accept usernames and retrieving the input given by the user.

Currently trying to get my course-idea program to run. I noticed thatthe text "what is your username does not appear in the textbox located at localhost:4567. Also whenever a username is typed into the box the website does not display the username. Any info or help would be highly appreciated. https://github.com/casse1hb/course-ideas-spark

In your get method, you need to add the model to your template like this:

        get("/", (req, res) -> {
            Map<String, String> model = new HashMap<>();
            model.put("username" , req.cookie("username"));
            return new ModelAndView(model, "index.hbs");
        }, new HandlebarsTemplateEngine());

instead of:

        get("/", (req, res) -> {
            Map<String, String> model = new HashMap<>();
            model.put("username" , req.cookie("username"));
            return new ModelAndView(null, "index.hbs");
        }, new HandlebarsTemplateEngine());

You also seem to have a typo in several places in your post method: "sing-in" instead of "sign-in".

For the placeholder, I'm not sure why you're not seeing it.
