You can send performance budget alerts straight to your Slack channel.
1. Search the Slack app directory for "Incoming Webhooks" and then click "Add Configuration".
2. Choose the Slack channel you'd like the alerts sent to and click "Add incoming Webhooks Integration".
3. Copy the "Webhook URL" you're given by Slack. In your SpeedCurve settings add a new "Webhook" and paste in the Slack Webhook URL.
4. For each performance budget in SpeedCurve make sure that you have Notifications turned on.
You'll then get an alert in your Slack channel every time a performance budget alert is sent.
