I've used mirage extensively throughout the past 5+ years across multiple projects/teams and it truly is a great tool. In a recent project we had multiple "scenarios" defined that represented different high-level states of the app. We added a page that allowed switching between the scenarios during local development and it was a huge boon to productivity, while also allowing us to write certain automated smoke tests that otherwise would have been more cumbersome with e.g. selenium.

Working on a React project recently, I was surprised that there wasn't an option like mirage, but now that there is, I highly recommend it!
