<!--preview-cmd-->
|
|
```bash [Terminal]

<!--/preview-cmd-->

|
|
|
The `preview` command starts a server to preview your Nuxt application after running the `build` command. The `start` command is an alias for `preview`. When running your application in production refer to the [Deployment section](/docs/getting-started/deployment).
|
|
|
|
## Arguments
|
|
|
|
<!--preview-args-->
|
|
Argument | Description
|
|
--- | ---
|
|
`ROOTDIR="."` | Specifies the working directory (default: `.`)
|
|
<!--/preview-args-->
|
|
|
|
## Options
|
|
|
|
<!--preview-opts-->
|
|
Option | Default | Description
|
|
--- | --- | ---
|
|
`--cwd=<directory>` | | Specify the working directory, this takes precedence over ROOTDIR (default: `.`)
|
|
`--logLevel=<silent\|info\|verbose>` | | Specify build-time log level
|
|
`--envName` | | The environment to use when resolving configuration overrides (default is `production` when building, and `development` when running the dev server)
|
|
`--dotenv` | | Path to `.env` file to load, relative to the root directory
|
|
<!--/preview-opts-->
|
|
|
|
This command sets `process.env.NODE_ENV` to `production`. To override, define `NODE_ENV` in a `.env` file or as command-line argument.
|
|
|
|
::note
|
|
For convenience, in preview mode, your [`.env`](/docs/guide/directory-structure/env) file will be loaded into `process.env`. (However, in production you will need to ensure your environment variables are set yourself.)
