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.

Sinatra 3.0 Was Released; Did Anyone Notice? — One of Ruby’s most popular and long standing ways to build webapps (and the original inspiration for Node’s Express) has had a major update, though it doesn’t seem to be getting discussed anywhere yet (no post on the official Sinatra blog either). We’re still digging into this and will cover it in more depth next week, but.. it’s out!

Put: A Better Way to Sort Ruby Objects? — The go-to way to sort Ruby objects by complex criteria is Enumerable’s sort_by method. The new Put library, however, aims to make such sorting clearer, terser, and nil-safe. There’s even a screencast showing it off.
