### Synopsis

```bash
npm pack [[<@scope>/]<pkg>...] [--dry-run] [--json]
```

### Configuration

<!-- AUTOGENERATED CONFIG DESCRIPTIONS START -->
<!-- automatically generated, do not edit manually -->
#### `dry-run`

* Default: false
* Type: Boolean

Indicates that you don't want npm to make any changes and that it should
only report what it would have done. This can be passed into any of the
commands that modify your local installation, eg, `install`, `update`,
`dedupe`, `uninstall`, as well as `pack` and `publish`.

Note: This is NOT honored by other network related commands, eg `dist-tags`,
`owner`, etc.

#### `json`

* Default: false
* Type: Boolean

Whether or not to output JSON data, rather than the normal output.

Not supported by all npm commands.

#### `workspace`

* Default:
* Type: String (can be set multiple times)

Enable running a command in the context of the configured workspaces of the
current project while filtering by running only the workspaces defined by
this configuration option.

Valid values for the `workspace` config are either:

* Workspace names
* Path to a workspace directory
* Path to a parent workspace directory (will result to selecting all of the
  nested workspaces)

When set for the `npm init` command, this may be set to the folder of a
workspace which does not yet exist, to create the folder and set it up as a
brand new workspace within the project.

This value is not exported to the environment for child processes.

#### `workspaces`

* Default: false
* Type: Boolean

Enable running a command in the context of **all** the configured
workspaces.

This value is not exported to the environment for child processes.

### Description

For anything that's installable (that is, a package folder, tarball,
tarball url, git url, name@tag, name@version, name, or scoped name), this
command will fetch it to the cache, copy the tarball to the current working
directory as `<name>-<version>.tgz`, and then write the filenames out to
stdout.

If the same package is specified multiple times, then the file will be
overwritten the second time.

If no arguments are supplied, then npm packs the current package folder.
