I have a quick question about self-hosting a Next.js server on my own virtual server. I currently run a few Next.js websites that receive quite a fair amount of traffic. Every few days, I'll perform a pull on the production server and use next build. Sometimes while the application is building, I will receive traffic to my website will almost certainly results in both a client and server error. What is the best practice for updating the application? Should I always shutdown before building, then start it back up? There must be a better way to avoid downtime, like a zero downtime deployment...
