vercel build command can be used to build a Vercel Project locally or in your own CI environment.
Build artifacts are placed into the
.vercel/output directory according to the
Build Output API.
When used in conjunction with the
vercel deploy --prebuilt command, this allows a Vercel Deployment
to be created without sharing the Vercel Project's source code with Vercel.
This command can also be helpful in debugging a Vercel Project by receiving error messages for a failed build locally, or by inspecting the resulting build artifacts to get a better understanding of how Vercel will create the Deployment.
It is recommended to run the
vercel pull command before invoking
vercel build to ensure that
you have the most recent Project Settings and Environment Variables stored locally.
These are options that only apply to the
vercel build command, therefore, more information is provided.
--prod option can be specified when you want to build the Vercel Project using Production Environment Variables. By default, the Preview Environment Variables will be used.
vercel build --prod
--yes option can be used to bypass the confirmation prompt and automatically pull environment variables and Project Settings if not found locally.
vercel build --yes
