vercel command is used to deploy Vercel Projects and can be used from either the root of the Vercel Project directory or by providing a path.
You can alternatively use the
vercel deploy command for the same effect, if you want to be more explicit.
When deploying, stdout is always the Deployment URL.
vercel > deployment-url.txt
You can build Vercel projects locally to inspect the build outputs before they are deployed. This is a great option for producing builds for Vercel that do not share your source code with the platform.
It's also useful for debugging build outputs.
vercel deploy --prebuilt
