# `Chime.Channels.Slack`
[🔗](https://github.com/hattoriai/chime/blob/v0.1.0-dev/lib/chime/channels/slack.ex#L1)

Slack: a message to a person, or to a channel of the team's.

    channels: [slack: {Chime.Channels.Slack, token: System.fetch_env!("SLACK_BOT_TOKEN")}]

With a bot's `:token`, Chime posts with `chat.postMessage` to the
person's Slack id (or a channel's), from the recipient's data
(`data.slack`, or `to: {:data, :slack_id}`), or to one `to:
"#alerts"` for everyone. Without a token, the address is an incoming
webhook's URL (`to: "https://hooks.slack.com/services/..."`, or each
person's in their data).

It says the notifier's `slack/3` when it has one (a text, or a map of
`:title`, `:body`, `:url`), else the feed's words, with the link that
reads the notification. Options: `:token`, `:to`, `:req_options`.
