# npm-shrinkwrap(1)
## Lock down dependency versions for publication
### 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-locks](/configuring-npm/package-locks).
