nuxi preview

npx nuxi preview [rootDir]

The preview command starts a server to preview your Nuxt application after running the build command.

This command sets process.env.NODE_ENV to production. To override, define NODE_ENV in a .env file or as command-line argument.

For convenience, in preview mode, your .env file will be loaded into process.env. (However, in production you will need to ensure your environment variables are set yourself.)
