### Synopsis

```bash
npm shrinkwrap
```

### 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).
