Elixir em Foco is the podcast of the Brazilian community of Elixir, the programming language created by Brazilian José Valim that is used by companies around the world to develop scalable and easy-to-maintain applications. Elixir runs on the Erlang virtual machine, known for enabling the creation of low-latency, distributed, and fault-tolerant systems. These features, combined with Elixir’s tools, allow developers to be productive in a variety of domains, such as web development, embedded software, machine learning, data pipelines, and multimedia processing, across a wide range of industries.

There is a learning curve to get started with the Elixir Phoenix LiveView stack and to appreciate what makes it such a nice environment. I want to share my journey learning Elixir Phoenix LiveView in the beginning of 2025 and the resources that I used. Things may feel overwhelming but there is great material out there.
