|
| <pre><code class="language-bash">npm find-dupes
|
| </code></pre>
|
| <h3 id="description">Description</h3>
|
| <p>Runs <code>npm dedupe</code> in <code>--dry-run</code> mode, making npm only output the duplications, without actually changing the package tree.</p>
|
| <h3 id="configuration">Configuration</h3>
|
| <h4 id="install-strategy"><code>install-strategy</code></h4>
|
| <ul>
|
| <li>Default: "hoisted"</li>
|
| <li>Type: "hoisted", "nested", "shallow", or "linked"</li>
|
| </ul>
|
| <p>Sets the strategy for installing packages in node_modules. hoisted
|
| (default): Install non-duplicated in top-level, and duplicated as necessary
|
| within directory structure. nested: (formerly --legacy-bundling) install in
|
| place, no hoisting. shallow (formerly --global-style) only install direct
|
| deps at top-level. linked: (experimental) install in node_modules/.store,
|
| link in place, unhoisted.</p>
|
| <h4 id="legacy-bundling"><code>legacy-bundling</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| <li>DEPRECATED: This option has been deprecated in favor of
|
| <code>--install-strategy=nested</code></li>
|
| </ul>
|
| <p>Instead of hoisting package installs in <code>node_modules</code>, install packages in
|
| the same manner that they are depended on. This may cause very deep
|
| directory structures and duplicate package installs as there is no
|
| de-duplicating. Sets <code>--install-strategy=nested</code>.</p>
|
| <h4 id="global-style"><code>global-style</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| <li>DEPRECATED: This option has been deprecated in favor of
|
| <code>--install-strategy=shallow</code></li>
|
| </ul>
|
| <p>Only install direct dependencies in the top level <code>node_modules</code>, but hoist
|
| on deeper dependencies. Sets <code>--install-strategy=shallow</code>.</p>
|
| <h4 id="strict-peer-deps"><code>strict-peer-deps</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>If set to <code>true</code>, and <code>--legacy-peer-deps</code> is not set, then <em>any</em>
|
| conflicting <code>peerDependencies</code> will be treated as an install failure, even
|
| if npm could reasonably guess the appropriate resolution based on non-peer
|
| dependency relationships.</p>
|
| <p>By default, conflicting <code>peerDependencies</code> deep in the dependency graph will
|
| be resolved using the nearest non-peer dependency specification, even if
|
| doing so will result in some packages receiving a peer dependency outside
|
| the range set in their package's <code>peerDependencies</code> object.</p>
|
| <p>When such an override is performed, a warning is printed, explaining the
|
| conflict and the packages involved. If <code>--strict-peer-deps</code> is set, then
|
| this warning is treated as a failure.</p>
|
| <h4 id="package-lock"><code>package-lock</code></h4>
|
| <ul>
|
| <li>Default: true</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>If set to false, then ignore <code>package-lock.json</code> files when installing. This
|
| will also prevent <em>writing</em> <code>package-lock.json</code> if <code>save</code> is true.</p>
|
| <h4 id="omit"><code>omit</code></h4>
|
| <ul>
|
| <li>Default: 'dev' if the <code>NODE_ENV</code> environment variable is set to
|
| 'production'; otherwise, empty.</li>
|
| <li>Type: "dev", "optional", or "peer" (can be set multiple times)</li>
|
| </ul>
|
| <p>Dependency types to omit from the installation tree on disk.</p>
|
| <p>Note that these dependencies <em>are</em> still resolved and added to the
|
| <code>package-lock.json</code> or <code>npm-shrinkwrap.json</code> file. They are just not
|
| physically installed on disk.</p>
|
| <p>If a package type appears in both the <code>--include</code> and <code>--omit</code> lists, then
|
| it will be included.</p>
|
| <p>If the resulting omit list includes <code>'dev'</code>, then the <code>NODE_ENV</code> environment
|
| variable will be set to <code>'production'</code> for all lifecycle scripts.</p>
|
| <h4 id="include"><code>include</code></h4>
|
| <ul>
|
| <li>Default:</li>
|
| <li>Type: "prod", "dev", "optional", or "peer" (can be set multiple times)</li>
|
| </ul>
|
| <p>Option that allows for defining which types of dependencies to install.</p>
|
| <p>This is the inverse of <code>--omit=<type></code>.</p>
|
| <p>Dependency types specified in <code>--include</code> will not be omitted, regardless of
|
| the order in which omit/include are specified on the command-line.</p>
|
| <h4 id="ignore-scripts"><code>ignore-scripts</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>If true, npm does not run scripts specified in package.json files.</p>
|
| <p>Note that commands explicitly intended to run a particular script, such as
|
| <code>npm start</code>, <code>npm stop</code>, <code>npm restart</code>, <code>npm test</code>, and <code>npm run</code> will still
|
| run their intended script if <code>ignore-scripts</code> is set, but they will <em>not</em>
|
| run any pre- or post-scripts.</p>
|
| <h4 id="audit"><code>audit</code></h4>
|
| <ul>
|
| <li>Default: true</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>When "true" submit audit reports alongside the current npm command to the
|
| default registry and all registries configured for scopes. See the
|
| documentation for <a href="../commands/npm-audit.html"><code>npm audit</code></a> for details on what is
|
| submitted.</p>
|
| <h4 id="bin-links"><code>bin-links</code></h4>
|
| <ul>
|
| <li>Default: true</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>Tells npm to create symlinks (or <code>.cmd</code> shims on Windows) for package
|
| executables.</p>
|
| <p>Set to false to have it not do this. This can be used to work around the
|
| fact that some file systems don't support symlinks, even on ostensibly Unix
|
| systems.</p>
|
| <h4 id="fund"><code>fund</code></h4>
|
| <ul>
|
| <li>Default: true</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>When "true" displays the message at the end of each <code>npm install</code>
|
| acknowledging the number of dependencies looking for funding. See <a href="../commands/npm-fund.html"><code>npm fund</code></a> for details.</p>
|
| <h4 id="workspace"><code>workspace</code></h4>
|
| <ul>
|
| <li>Default:</li>
|
| <li>Type: String (can be set multiple times)</li>
|
| </ul>
|
| <p>Enable running a command in the context of the configured workspaces of the
|
| current project while filtering by running only the workspaces defined by
|
| this configuration option.</p>
|
| <p>Valid values for the <code>workspace</code> config are either:</p>
|
| <ul>
|
| <li>Workspace names</li>
|
| <li>Path to a workspace directory</li>
|
| <li>Path to a parent workspace directory (will result in selecting all
|
| workspaces within that folder)</li>
|
| </ul>
|
| <p>When set for the <code>npm init</code> command, this may be set to the folder of a
|
| workspace which does not yet exist, to create the folder and set it up as a
|
| brand new workspace within the project.</p>
|
| <p>This value is not exported to the environment for child processes.</p>
|
| <h4 id="workspaces"><code>workspaces</code></h4>
|
| <ul>
|
| <li>Default: null</li>
|
| <li>Type: null or Boolean</li>
|
| </ul>
|
| <p>Set to true to run the command in the context of <strong>all</strong> configured
|
| workspaces.</p>
|
| <p>Explicitly setting this to false will cause commands like <code>install</code> to
|
| ignore workspaces altogether. When not set explicitly:</p>
|
| <ul>
|
| <li>Commands that operate on the <code>node_modules</code> tree (install, update, etc.)
|
| will link workspaces into the <code>node_modules</code> folder. - Commands that do
|
| other things (test, exec, publish, etc.) will operate on the root project,
|
| <em>unless</em> one or more workspaces are specified in the <code>workspace</code> config.</li>
|
| </ul>
|
| <p>This value is not exported to the environment for child processes.</p>
|
| <h4 id="include-workspace-root"><code>include-workspace-root</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>Include the workspace root when workspaces are enabled for a command.</p>
|
| <p>When false, specifying individual workspaces via the <code>workspace</code> config, or
|
| all workspaces via the <code>workspaces</code> flag, will cause npm to operate only on
|
| the specified workspaces, and not on the root project.</p>
|
| <p>This value is not exported to the environment for child processes.</p>
|
| <h4 id="install-links"><code>install-links</code></h4>
|
| <ul>
|
| <li>Default: false</li>
|
| <li>Type: Boolean</li>
|
| </ul>
|
| <p>When set file: protocol dependencies will be packed and installed as regular
|
| dependencies instead of creating a symlink. This option has no effect on
|
| workspaces.</p>
