Server-Timing response headers will pass through to the client
Vercel announced that Server-Timing response headers will now pass through to the client. This update means that information contained within these headers, which are used to communicate performance metrics and timing details from the server, will be directly accessible to the client-side environment. This change affects how Vercel's platform processes and forwards HTTP response headers, specifically enabling the Server-Timing header to reach the end-user's browser. The direct transmission of these headers is intended to provide developers with enhanced visibility into server-side operations, facilitating more precise performance analysis and debugging efforts for applications deployed on Vercel.
Developers can now directly access server-side performance metrics in the client for debugging and optimization.
