Slim Logger

A single-line logger implementation to replace the default Phoenix logger.

This is a fork of Phoenix.Logger designed to produce slimmer, single-line log entries for requests. At the moment, only standard request logs have been slimmed down.

Installation

The package can be installed by adding slim_logger to your list of dependencies in mix.exs:

def deps do
  [
    {:slim_logger, "~> 0.3.0"}
  ]
end

To get started, disable the default Phoenix logger in config:

# config/config.exs

# Disable the default `Phoenix.Logger` so we can use `SlimLogger` instead.
config :phoenix, :logger, false

Then, in your application file, call the install function:

# lib/my_app/application.ex

defmodule MyApp.Application do
  use Application

  @impl true
  def start(_type, _args) do
    children = [
      # ...
    ]

    # Install the slim logger
    SlimLogger.install()

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

If your application is deployed behind a proxy (that sets X-Forwarded-For headers, for example), use the RemoteIp to rewrite Plug.Conn' s remote_ip based on forwarding headers.
