Serverless Pre-Rendering

Speeding up serverless function response times in deployments like in Vercel

Extracted from the following link.

Just add the following code where you can access the response object.

res.setHeader("Cache-Control", "s-maxage=1, stale-while-revalidate");

Set the s-maxage value according to how long you want the CDN to cache the response (in seconds).
