webpack-dev-server to return auto-generated for specific URL?

I have a single page app which connects to a back-end REST API on a different server.

On index.html app load, first thing it does is GET /env.json which contains the URL for the REST API server. Obviously, it is different in prod than in test than in dev.

Is there any way I can add middleware to the webpack-dev-server so that when it sees GET /env.json it serves up automatically generated json (based on env var or other)?

If there is an easier way, I am open to it. My assumption was that dev and test would start a backend server and then configure response to GET /env.json, while prod would have a different file added or dynamically generated.

According to webpack-dev-server source code there is setup option which takes app (instance of express) variable as function argument. So, you can manipulate routes by specifying this option in your config:

devServer: {
    setup: function(app) {
        app.get('env.json', function(req, res) {
            // ...
        });
    }
}
