Error tracking and reporting to Slack.

A simple post-to-Slack reporter for Tower error handler.

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

# mix.exs

def deps do
  [
    {:tower_slack, "~> 0.6.2"}
  ]
end

$ mix tower_slack.install

Register the reporter with Tower.

# config/config.exs

config(
  :tower,
  :reporters,
  [
    # along any other possible reporters
    TowerSlack
  ]
)

And make any additional configurations specific to this reporter.

# config/runtime.exs

config :tower_slack,
  otp_app: :your_app,
  webhook_url: System.get_env("TOWER_SLACK_WEBHOOK_URL"),
  environment: System.get_env("DEPLOYMENT_ENV", to_string(config_env()))

Instructions to create the Slack Webhook URL in https://api.slack.com/messaging/webhooks.

That's it. There's no extra source code needed to get reports in Slack.

Tower will automatically report any errors (exceptions, throws or abnormal exits) occurring in your application. That includes errors in any plug call (including Phoenix), Oban jobs, async task or any other Elixir process.

You can additionally, manually report errors just by informing Tower about any manually caught exceptions, throws or abnormal exits.

E.g.

try do
  # possibly crashing code
rescue
  exception ->
    Tower.report_exception(exception, __STACKTRACE__)
end
