From self-taught web dev, through many roles and currently running a small consultancy, it has always been a journey of curiosity. Fundamentally driven by cool concepts and projects. Lars runs the Underjord.io blog, newsletter and YouTube to share and spread his curiosity about the Elixir and the BEAM along with a few other computery topics. In community collaborations you’ll find him on BEAM Radio and creating the Nerves project Newsletter as well as working with companies to help them find the great Elixir developers that are out there. Originally from the north of Sweden, he and his family live in a small rural town along Sweden’s west coast, near Varberg.
Sometimes people ask for an example of an Elixir application. NervesHub is an open source application used in production at scale with a lively development history. It has been through a lot of change, a lot of evolution.
And it uses a lot of the Elixir ecosystem. Phoenix, Ecto, LiveView, Oban, thousands of WebSocket connections, an Erlang distribution cluster, a lot of PubSub, regular GenServers, PhoenixTest and much more.
This talk will give a tour of the project, focusing on interesting things, changes that have simplified the system over time. Choices that have been made and hopefully the good reasons behind them.
Talk objectives:
Give people a real Phoenix example to reference, study and maybe help improve?
NervesHub is not unique but tells many of the common Elixir stories very concretely. The removal of extra infrastructure that is possible thanks to the BEAM ecosystem and the power of LiveView in building a powerful SaaS product with limited means.
Target audience:
Web developers, Phoenix enthusiasts, Elixir developers. But mostly anyone in the ecosystem.
