The Next.js website is served through multiple Azure functions. The basic-nextjs-azure-functions package contains these functions.
nextjsserver - The actual Next.js web server, including Incremental Static Regeneration.
serveStaticFile - A function to serve all static files from the _next/static path.
Handling of routing is managed through the Azure functions proxy functionality as configured in proxies.json:
_next/static/*files are redirected to theserveStaticFilefunction- all other files are redirected to the
nextjsserverfunction
