Plugsnag

Report errors in your Plug stack or whatever to Bugsnag, because that's a super great place to send your errors.

Installation/Usage

Just throw it in your deps in your mix.exs:

  defp deps do
    [{:plugsnag, "~> 1.3.0"}]
  end

Then you'll need to configure it with your API key as per the bugsnag-elixir docs.

Now you'll need to call Bugsnag.start to warm up the card, and then use it, for example in your Phoenix.Router.

defmodule YourApp.Router do
  use Phoenix.Router
  use Plugsnag

  # ...
end

Filtering Parameters

By default, the BasicErrorReportBuilder will filter out password parameters from error reports sent to Bugsnag. You can customize this list inside your configuration:

config :plugsnag, :filter_parameters, ~w(password password_confirmation super_sekrit)

Customizing error reporting

You can also customize how an error is sent to bugsnag-elixir by passing your own custom ErrorReportBuilder with the :error_report_builder option.

defmodule YourApp.Router do
  use Phoenix.Router
  use Plugsnag, error_report_builder: YourApp.ErrorReportBuilder

  # ...
end

defmodule YourApp.ErrorReportBuilder do
  @behaviour Plugsnag.ErrorReportBuilder

  def build_error_report(error_report, conn) do
    error_report
    |> Plugsnag.BasicErrorReportBuilder.build_error_report(conn)
    |> put_user_info(conn)
  end

  defp put_user_info(error_report, conn) do
    current_user = conn.assigns[:current_user]

    user_info =  %{
      id: current_user.id
    }

    %{error_report | user: user_info}
  end
end
