How to configure Slack alerts in Errsole

When your app crashes or encounters a critical error, Errsole immediately sends an alert. You can route these alerts to a Slack channel—so your team is notified the moment something breaks.

 The error alert includes the error message, the app name, the environment, the server name, and a direct link to view the error in your logs.

Step 1: Get your Slack webhook URL

To start, create or copy an existing Slack webhook URL by following Slack’s guide here: https://api.slack.com/messaging/webhooks

Step 2: Configure Slack alerts in Errsole

You can configure Slack alerts in two ways:

Option A: Configure via Code

Add your Slack webhook URL directly in the errsole.initialize function:

errsole.initialize({
  storage: new ErrsoleSQLite(logFile),
  appName: 'your-app-name',
  integrations: {
    slack: {
      url: 'https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX'
    }
  }
});

Option B: Configure via the Errsole Dashboard

1. Go to your Errsole Dashboard
2. Navigate to Settings > Integrations > Slack
3. Enter your Slack webhook URL
4. Save the configuration
5. Click the “Test Notification” button to verify the setup

If everything is configured correctly, you’ll receive a test alert in your Slack channel.

Conclusion

That’s it! With Slack alerts enabled, your team stays in the loop the moment something breaks.
