Phoenix LiveView

Although it had already been announced (but not released yet), Phoenix LiveView was presented to the audience at Lonestar ElixirConf with a promise from Chris McCord to be released as early as the end of the month but at least in the coming months.

Chris spoke about the motivations for building LiveView and stressed the goal of delaying the inevitable single page application path for as long as possible. How long that is will be determined after release when people have had time to use it.

I am personally quite optimistic about it and although I’m happy to keep writing JavaScript on the frontend whenever I need to, it will make building prototype apps to showcase Elixir’s real-time capabilities much easier.

The conceptual programming model for LiveView is very similar to that of React and other JavaScript libraries, in that each component has a parent-child relationship, with the default behaviour that if a child component fails, it can be restarted back to its last known state. It is in this way they behave like children in a supervision tree. The similarities between frontend view libraries like React and Elixir/Erlang supervision Trees is a topic I have written about before.

LoneStar Elixir 2019 - anyone go?

Also from Chris’s LoneStar talk he had just finished the implementation to run tests against LiveView, and before release wanted to implement LiveView generators and polish the documentation and guides.

LoneStar Elixir 2019 - anyone go?

I hoped to see his talk on YouTube, but for some reason, it wasn‘t even recorded:


I heard the video person showed up late and Chris was almost done with his speech! That’s very bad luck for the hundreds of us who couldn’t make it to Austin but are dying to hear him discuss LiveView!!

Let’s hope the videographer for Elixirconf EU doesn’t drop the ball as the speech should be similar.


If I were Chris I’d start wondering whether the videographers have it in for me. Didn’t the audio get messed up fron another keynote he did?


Yeah it happened at ElixirConf 2016 in Orlando. Not sure what he did to deserve this!
