About This Article
Chamod Lakmal's team didn't notice crashes affecting hundreds of users until Monday morning, even though they'd been happening all weekend. By then, the damage to the app's reputation and user retention was already done.
He set up a serverless Firebase Cloud Function with the onNewFatalIssuePublished trigger and connected it to Google Chat webhooks. Now when crashes happen, the team gets automatic alerts in their chat with the app ID, version, issue type, and title all formatted and ready to read.
Critical crashes now get responses in minutes instead of hours. Users don't experience extended outages, and the team stopped worrying about missing issues. The whole thing took 20 minutes to deploy and requires no server maintenance.
