Single Page Application

You're building a web app with client-side routing, so mark index.html as the SPA.

$ ws --spa index.html

By default, typical SPA paths (e.g. /user/1, /login) would return 404 Not Found as a file does not exist with that path. By marking index.html as the SPA you create this rule:

If a static file at the requested path exists (e.g. /css/style.css) then serve it, if it does not (e.g. /login) then serve the specified SPA and handle the route client-side.
