149<p><code>npm-shrinkwrap.json</code> is a file created by <a href="../commands/npm-shrinkwrap.html"><code>npm shrinkwrap</code></a>. It is identical to
150<code>package-lock.json</code>, with one major caveat: Unlike <code>package-lock.json</code>,
151<code>npm-shrinkwrap.json</code> may be included when publishing a package.</p>
152<p>The recommended use-case for <code>npm-shrinkwrap.json</code> is applications deployed
153through the publishing process on the registry: for example, daemons and
154command-line tools intended as global installs or <code>devDependencies</code>. It's
155strongly discouraged for library authors to publish this file, since that
156would prevent end users from having control over transitive dependency
157updates.</p>
158<p>If both <code>package-lock.json</code> and <code>npm-shrinkwrap.json</code> are present in a
159package root, <code>npm-shrinkwrap.json</code> will be preferred over the
160<code>package-lock.json</code> file.</p>
161<p>For full details and description of the <code>npm-shrinkwrap.json</code> file format,
162refer to the manual page for
163<a href="../configuring-npm/package-lock-json.html">package-lock.json</a>.</p>
