Usage

In order to send a notification to slack, you can write a method like the following.

  def notifier
    message = FDE::Slack::Message.new(
      'your message title',
      fields,
      {
        title_link:
          {
            title: 'title',
            title_link: 'title',
            thumb_url: 'author_icon'
          },
        footer: FDE::Slack::Footer.new('footer_text).to_h
      }
    )

    message.info(channel)
  end


  # create a hash for your required fields
    def fields
      [
        {
          title: 'Field 1',
          value: 'value 1',
          short: false
        },
        {
          title: 'Field 2',
          value: 'value 2',
          short: false
        },  
      ]
    end

Configuration

To set the hook_url value, you may have an initializer under config/initializers like this

require "slack/notification"

FDE::Slack::Notification.configure do |config|
  config.webhook = 'hook_url'
end

Styling

Any of these methods can be used to get the following colored sidebars

1. message.info(channel) # BLUE
2. message.success(channel) # GREEN
3. message.error(channel) # RED
4. message.warning(channel) # YELLOW
