Have you looked at http://seaside.st/ http://seaside.st/ ? Seaside has been around for a while; it offers a component based approach to building web applications from objects, including an in-browser way to inspect and modify the code of displayed components. It also offers a DSL for writing HTML, along with some support for jquery. There is also a free book to teach how to use Seaside to develop webapps, including dynamic frontends (but not a full SPA, I think): http://book.seaside.st/book http://book.seaside.st/book Seaside explicitly chose a "heterodox" approach in being session based and producing URLs that are clearly not RESTful. That being said, the Seaside book covers the Seaside REST package which handles building RESTful APIs.
