Custom URL for Dashboard

The documentation for the UI Node says you can change the main endpoint as below. I don't think you can change the address of the tabs.

The last post in here, with some modification might work for you - Configuring a dashboard tab in response to a URL - #6 by Nxito

The default url for the dashboard is based off your existing Node-RED httpRoot path with /ui added. This can be changed in your Node-RED settings.js file - ui: { path: "ui" },

You can also add your own express middleware to handle requests by using the ui: { middleware: your_function } property in settings.js. For example

ui: { path: 'ui', middleware: function (req, res, next) {
            // Do something more interesting here.
            console.log('LOGGED')
            next()
        }
    },
