Next.js - How to Test a Build Locally to Detect Differences

Coming to Next from Gatsby. Is there a equivalent for testing a build locally to detect for differences?
For Gatsby I’d run

gatsby build && gatsby serve

I believe

next build && next start

is the equivalent (CLI docs )

next start

starts the application in production mode. The application should be compiled with

next build

first.

Perfect.

Yes, was writing exactly the same. If you want to test static exports, you’d run

next build && next export

and then serve the contents from your build dir 🙂
