[2019-03-18] New GraphQL course; Phoenix LiveView is now available; The value of older coders; All glory to the monolith

We’ve released a new course, GraphQL: Zero to Awesome. In it, we build a GraphQL forum backend in both Elixir and JavaScript, and write clients for it in Vue, React Native, Elm, and Flutter. There’s over four and a half hours of content, and all of the code is open source. We would be extremely grateful if you’d give it a look and share it with your friends. If you like SmoothTerminal/DailyDrip, help support us by buying a subscription to our courses. [don’t click this]
