The core of Nots.io is built on top of Elixir Phoenix framework. It’s stable, well designed, modern, pretty extensible with lots of great libs for essential web development needs. The production version of it is all about handling HTTP/1.1 requests. But it turns out it’s surprisingly easy to add HTTP/2 support into existing Phoenix application. This is a post in “Less is more” series on little nifty tech things which pop up while we’re working on Nots.
