“Elixir е динамичен, функционален език, измислен за създаването на лесни за разширение и поддръжка приложения.” — elixir-lang.org
Elixir се възползва от доказалата се в битки Erlang VM (BEAM) за създаването на разпределени и възстановяващи се от грешки системи с ниско време на реакция без специални конфигурации.
Свойства на езика:
iex> defmodule Hello do
...> def print(lang \\ :en)
...> def print(:de), do: "Hallo Welt"
...> def print(:en), do: "Hello World"
...> def print(:es), do: "Hola Mundo"
...> def print(:ru), do: "Привет мир"

iex> Hello.print()
"Hello World!"
iex> Hello.print(:es)
"Hola Mundo"
iex> Hello.print(:ru)
"Привет мир"
It’s easy to end up with an overly complex LiveView that houses lots of business rules and responsibilities. We can use Phoenix.LiveComponent to build a LiveView feature that is clean, maintainable and adherent to the Single Responsibility Principle.
Follow along as we use build Elixir School’s Slack invite portal: Admissions.
We’ll use LiveView’s live_link/2 together with the handle_params/3 callback to allow users to sort a table in real-time.
The release of Elixir 1.9 gave us mix release and the ability to support basic releases, runtime configuration and more, natively in Elixir. Learn how we were able to build a production release of an Elixir umbrella app with Docker, mix release and the new Config module.
We had a great time at ElixirConf 2019! Hear about Elixir School’s two workshops, along with the highlight talks and activities that we enjoyed this year.

Before you reach for adding another association to your schema, consider using Ecto.Query#select_merge/3 with a virtual field instead.
