I’ve always been wary of the performance hit that comes with server-side authentication. Each check can mean a slow network round-trip, which really adds up. But with Supabase’s new JWT Signing Keys, everything changes. Now, you can validate user sessions locally within your own application. This is a huge performance win! It eliminates that auth-related network latency, making for a much snappier user experience. It’s a great example of a modern, edge-friendly solution to a common bottleneck that typically slows down our apps.
To see this in action, check out the video by Jon Meyers. He walks through the entire process, from enabling the feature to refactoring a Next.js app to take full advantage of it.
