“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"
...> end
iex> Hello.print()
"Hello World!"
iex> Hello.print(:es)
"Hola Mundo"
iex> Hello.print(:ru)
"Привет мир"
In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part III we’ll incorporate Erlang’s telemetry_poller library into our Phoenix app so that we can observe and report on Erlang VM Telemetry events.
In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part III we’ll examine Phoenix and Ecto’s out-of-the-box Telemetry events and use Telemetry.Metrics to observe a wide-range of such events.
In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part II we’ll use Elixir’s Telemetry.Metrics and TelemetryMetricsStatsd libraries to define and send metrics to StatsD for a given Telemetry event.
The recent release of the LiveDashboard library allows us to visualize our application metrics, performance and behavior in real-time. In this post, we’ll add LiveDashboard to our Phoenix app, examine the out-of-the-box features and take a look under the hood to understand how LiveDashboard hooks into Telemetry events in order to visualize them.
In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part I we’ll start out by setting up a basic, DIY Telemetry pipeline and examining how Erlang’s Telemetry library works under the hood
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.
