A drop-in replacement for `:console`'s formatter. ExJsonLogger takes standard `Logger` calls and JSON encodes them.

Ecto and Plug loggers are also included.

## Installation

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

```elixir
def deps do
  [
    {:ex_json_logger, "~> 1.3.0"}
  ]
end
```

```elixir
config :logger, :console,
  format: {ExJsonLogger, :format},
  metadata: [
    :action,
    :controller,
    :duration,
    :format,
