Constructor Details

- (Middleware) initialize(app, home_page = nil)

Returns a new instance of Middleware

Parameters:

  • home_page (String) (defaults to: nil) —

    File to serve at the root. Handy for stand-alone projects. You can use a Closure Script, even in non-source folders, by using the url extension e.g. 'index.html' instead of the actual filename 'index.haml'.
