This Prebuilt Deployment example demonstrates how to output Vercel Serverless Functions that leverage the "prerender" feature using the Build Output API.
https://build-output-api-prerender-functions.vercel.sh
In this example, the Prerender function renders blog posts from an imaginary CMS "backend service". There are a few "popular" blog posts that are prerendered at build-time and placed into the static directory.
A Prerender function is a Serverless Function, in this case located at
.vercel/output/functions/blog/page.func, with an additional configuration file
located alongside the .func directory, in this case .vercel/output/functions/blog/page.prerender-config.json.
There is also a "route" in config.json that will direct all HTTP requests under the /blog/* prefix to invoke the Prerender Function.
The optional "fallback" file is also included, which will be served for blog posts that have not yet been rendered.
