How to use. Include <script>tag loaded from the CDN or local cloned exemplar.

<script src="hawk.js" async></script>

Source map support

Hawk supports JS SourceMaps for showing more useful information from your minified bundle. There a few conditions:

  1. Bundle ends with line contains anchor to the source map, like //# sourceMappingURL=all.min.js.map. It can be absolute or relative (relatively the bundle) path.
  2. Source map are publicly available by its URL.
  3. On every rebuilding you are updating the revision and pass it with `init` method. It can be heximal-hash or simply file's modification timestamp.

hawk.init({token: 'INTEGRATION_TOKEN', revision: 12345654345})


You can get notifications about catched errors to the Email, Telegram or Slack. For the last two types, we use Webhooks, so you free to use an any webhook bot, for example, our — @codex_bot.

Note about Webhook's query format. It is a POST-request with the message field contains notification's text.

To setup a Notifications, open the Settings page, find a Project and click on the «Configure Webhooks» button. Then add Webhook endpoints for the Slack or Telegram and press «Save». Don't forget to activate checkboxes for the selected types.


Hawk now in a public beta stage. So we allow to collect up to 10 000 events of different types by a Project. You can have a several Projects at one account.
