Synopsis

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.
