The Vercel and Sentry integration enables JavaScript developers to automatically generate releases whenever they deploy a new version of their app on Vercel, making it easier to track issues and identify root causes. The integration also ties code commits to the release, generates source maps, and surfaces information about the health of the release, such as the number of new issues seen and the scope of changes. This allows developers to quickly spot bugs and reduce the time between spotting a bug and finding its root cause. The integration is designed to work with Next.js frameworks on Vercel, but similar steps can be taken for other frameworks like Gatsby.
