RailsConf 2022 - RAILS_ENV=demo by Nathan Griffith

Today’s the day. You’ve prepared your pitch, deployed a special copy of your app, and confirmed—in a trial run—that your walkthrough is ready for a live audience. But, now, when you attempt to log in, something breaks. Flustered, you debug, apologize, and debug some more, before finally calling it quits. Next time, you’ll bring a prerecorded screencast... 😮‍💨 What could’ve been done to make the app more reliably "demoable"? Join us, as we use "stateful fakes" and "personas" to produce a testable, maintainable, and failure-resistant "demo" deployment, with production-like uptime guarantees!
