Inngest has released a new feature called CLI Replays in v0.5.0 that allows developers to test their code against real production data before deployment. This helps avoid breaking changes and gives confidence when deploying minor fixes or large refactors. The replay feature can be used for zero-effort testing, protecting against breaking changes, and reproducing production issues locally. It is particularly useful during the development of new functions triggered by existing events. Inngest encourages users to share their experiences with CLI Replays on GitHub or Discord and join their Discord community to provide feedback and shape future features.
