### Description
|
||
|
|
|
||
|
|
`npm-shrinkwrap.json` is a file created by [`npm
|
||
|
|
shrinkwrap`](/commands/npm-shrinkwrap). It is identical to
|
||
|
|
`package-lock.json`, with one major caveat: Unlike `package-lock.json`,
|
||
|
|
`npm-shrinkwrap.json` may be included when publishing a package.
|
||
|
|
|
||
|
|
The recommended use-case for `npm-shrinkwrap.json` is applications deployed
|
||
|
|
through the publishing process on the registry: for example, daemons and
|
||
|
|
command-line tools intended as global installs or `devDependencies`. It's
|
||
|
|
strongly discouraged for library authors to publish this file, since that
|
||
|
|
would prevent end users from having control over transitive dependency
|
||
|
|
updates.
|
||
|
|
|
||
|
|
If both `package-lock.json` and `npm-shrinkwrap.json` are present in a
|
||
|
|
package root, `npm-shrinkwrap.json` will be preferred over the
|
||
|
|
`package-lock.json` file.
|
||
|
|
|
||
|
|
For full details and description of the `npm-shrinkwrap.json` file format,
|
||
|
|
refer to the manual page for
|
||
|
|
[package-lock.json](/configuring-npm/package-lock-json).
