#  `Envio.Log`
**[Logger backend](https://hexdocs.pm/logger/Logger.html#module-backends) for [`Envío`](http://hexdocs.pm/envio) with _Slack_ logging out of the box**
## Installation
```elixir
def deps do
[
{:envio_log, "~> 0.1"}
]
end
```
## Usage
Put this into your `config/prod.exs`
```elixir
import Config
config :envio, :log,
level: :warn,
process_info: true
config :logger, backends: [Envio.Log.Backend], level: :debug
config :envio, :backends, %{
Envio.Slack => %{
{Envio.Log.Publisher, :info} => [
hook_url: {:system, "YOUR_SLACK_CHANNEL_API_ENDPOINT"}
]
}
}
```
You are all set! All the calls like:
```elixir
Logger.warn "Something happened", foo: :bar, answer: 42
```
will be automatically routed to the configured _Slack_ channel. All the calls to `Logger` with levels of the less priority than it was configured under `:envio, :log, :level` key will be purged in compile time.
