### Synopsis

```bash
npm shrinkwrap
```

Note: This command is unaware of workspaces.

### Description

This command repurposes `package-lock.json` into a publishable `npm-shrinkwrap.json` or simply creates a new one.
The file created and updated by this command will then take precedence over any other existing or future `package-lock.json` files.
For a detailed explanation of the design and purpose of package locks in npm, see [package-lock-json](/configuring-npm/package-lock-json).
