Lance Halvorsen shows us how to build our a guessing video game from the ground up using Elixir and OTP. In the end, he shows us how to build a fully working UI experience with Phoenix, Presence and Channels.

Learn how to use Phoenix LiveView for real-time features without complicated JS frameworks.

Integrate Phoenix PubSub with LiveView to build real-time features capable of broadcasting updates across a set of clients.

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

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 II we’ll use Elixir’s Telemetry.Metrics and TelemetryMetricsStatsd libraries to define and send metrics to StatsD for a given Telemetry event.

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 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.
