Phlex: A New Component-Oriented View Framework — Author Joel Drapper has certainly been putting in the effort since creating Phlex a few months ago. It lets you treat everything on a Web page as a distinct component and manage them all as plain old Ruby objects – the view format itself is also entirely pure Ruby which might remind you of _why’s Markaby a little! There’s a ERB to Phlex converter you can play with to see how it looks. GitHub repo.
