<div id="_content"><h3 id="description">Description</h3>
<p>npm gets its configuration values from the following sources, sorted by priority:</p>
<h4 id="command-line-flags">Command Line Flags</h4>
<p>Putting <code>--foo bar</code> on the command line sets the <code>foo</code> configuration
parameter to <code>"bar"</code>. A <code>--</code> argument tells the cli parser to stop
reading flags. Using <code>--flag</code> without specifying any value will set
the value to <code>true</code>.</p>
<p>Example: <code>--flag1 --flag2</code> will set both configuration parameters
to <code>true</code>, while <code>--flag1 --flag2 bar</code> will set <code>flag1</code> to <code>true</code>,
and <code>flag2</code> to <code>bar</code>. Finally, <code>--flag1 --flag2 -- bar</code> will set
both configuration parameters to <code>true</code>, and the <code>bar</code> is taken
as a command argument.</p>
<h4 id="environment-variables">Environment Variables</h4>
<p>Any environment variables that start with <code>npm_config_</code> will be
interpreted as a configuration parameter. For example, putting
<code>npm_config_foo=bar</code> in your environment will set the <code>foo</code>
configuration parameter to <code>bar</code>. Any environment configurations that
are not given a value will be given the value of <code>true</code>. Config
values are case-insensitive, so <code>NPM_CONFIG_FOO=bar</code> will work the
same. However, please note that inside <a href="../using-npm/scripts.html"><code>scripts</code></a>
npm will set its own environment variables and Node will prefer
those lowercase versions over any uppercase ones that you might set.
For details see <a href="https://github.com/npm/npm/issues/14528">this issue</a>.</p>
<p>Notice that you need to use underscores instead of dashes, so <code>--allow-same-version</code>
would become <code>npm_config_allow_same_version=true</code>.</p>
<h4 id="npmrc-files">npmrc Files</h4>
<p>The four relevant files are:</p>
<ul>
<li>per-project configuration file (<code>/path/to/my/project/.npmrc</code>)</li>
<li>per-user configuration file (defaults to <code>$HOME/.npmrc</code>; configurable via CLI
option <code>--userconfig</code> or environment variable <code>$NPM_CONFIG_USERCONFIG</code>)</li>
<li>global configuration file (defaults to <code>$PREFIX/etc/npmrc</code>; configurable via
CLI option <code>--globalconfig</code> or environment variable <code>$NPM_CONFIG_GLOBALCONFIG</code>)</li>
<li>npm's built-in configuration file (<code>/path/to/npm/npmrc</code>)</li>
</ul>
<p>See <a href="../configuring-npm/npmrc.html">npmrc</a> for more details.</p>
<h4 id="default-configs">Default Configs</h4>
<p>Run <code>npm config ls -l</code> to see a set of configuration parameters that are
internal to npm, and are defaults if nothing else is specified.</p>
<h3 id="shorthands-and-other-cli-niceties">Shorthands and Other CLI Niceties</h3>
<p>The following shorthands are parsed on the command-line:</p>

<p>If the specified configuration param resolves unambiguously to a known
configuration parameter, then it is expanded to that configuration
parameter. For example:</p>
<pre lang="bash"><code>npm ls --par
# same as:
npm ls --parseable
</code></pre>
<p>If multiple single-character shorthands are strung together, and the
resulting combination is unambiguously not some other configuration
param, then it is expanded to its various component pieces. For
example:</p>
<pre lang="bash"><code>npm ls -gpld
# same as:
npm ls --global --parseable --long --loglevel info
</code></pre>

<!-- raw HTML omitted -->
<h4 id="auth"><code>_auth</code></h4>
<ul>
<li>Default: null</li>
<li>Type: null or String</li>
</ul>
<p>A basic-auth string to use when authenticating against the npm registry.
This will ONLY be used to authenticate against the npm registry. For other
registries you will need to scope it like "//other-registry.tld/:_auth"</p>
<p>Warning: This should generally not be set via a command-line option. It is
safer to use a registry-provided authentication bearer token stored in the
~/.npmrc file by running <code>npm login</code>.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="access"><code>access</code></h4>
<ul>
<li>Default: 'restricted' for scoped packages, 'public' for unscoped packages</li>
<li>Type: null, "restricted", or "public"</li>
</ul>
<p>When publishing scoped packages, the access level defaults to <code>restricted</code>.
If you want your scoped package to be publicly viewable (and installable)
set <code>--access=public</code>. The only valid values for <code>access</code> are <code>public</code> and
<code>restricted</code>. Unscoped packages <em>always</em> have an access level of <code>public</code>.</p>
<p>Note: Using the <code>--access</code> flag on the <code>npm publish</code> command will only set
the package access level on the initial publish of the package. Any
subsequent <code>npm publish</code> commands using the <code>--access</code> flag will not have an
effect to the access level. To make changes to the access level after the
initial publish use <code>npm access</code>.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="all"><code>all</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>When running <code>npm outdated</code> and <code>npm ls</code>, setting <code>--all</code> will show all
outdated or installed packages, rather than only those directly depended
upon by the current project.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="allow-same-version"><code>allow-same-version</code></h4>
<ul>
<li>Default: false</li>

<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<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>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="audit-level"><code>audit-level</code></h4>
<ul>
<li>Default: null</li>
<li>Type: null, "info", "low", "moderate", "high", "critical", or "none"</li>
</ul>
<p>The minimum level of vulnerability for <code>npm audit</code> to exit with a non-zero
exit code.</p>
<!-- raw HTML omitted -->

<ul>
<li>Default: "legacy"</li>
<li>Type: "legacy", "web", "sso", "saml", "oauth", or "webauthn"</li>
</ul>
<p>NOTE: auth-type values "sso", "saml", "oauth", and "webauthn" will be
removed in a future version.</p>
<p>What authentication strategy to use with <code>login</code>.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="before"><code>before</code></h4>
<ul>
<li>Default: null</li>
<li>Type: null or Date</li>
</ul>
<p>If passed to <code>npm install</code>, will rebuild the npm tree such that only
versions that were available <strong>on or before</strong> the <code>--before</code> time get
installed. If there's no versions available for the current set of direct
dependencies, the command will error.</p>
<p>If the requested version is a <code>dist-tag</code> and the given tag does not pass the
<code>--before</code> filter, the most recent version less than or equal to that tag
will be used. For example, <code>foo@latest</code> might install <code>foo@1.2</code> even though
<code>latest</code> is <code>2.0</code>.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<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>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="browser"><code>browser</code></h4>
<ul>
<li>Default: OS X: <code>"open"</code>, Windows: <code>"start"</code>, Others: <code>"xdg-open"</code></li>

terminal.</p>
<p>Set to <code>true</code> to use default system URL opener.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="ca"><code>ca</code></h4>
<ul>
<li>Default: null</li>
<li>Type: null or String (can be set multiple times)</li>
</ul>
<p>The Certificate Authority signing certificate that is trusted for SSL
connections to the registry. Values should be in PEM format (Windows calls
it "Base-64 encoded X.509 (.CER)") with newlines replaced by the string
"\n". For example:</p>
<pre lang="ini"><code>ca="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"
</code></pre>
<p>Set to <code>null</code> to only allow "known" registrars, or to a specific CA cert to
trust only that specific signing authority.</p>
<p>Multiple CAs can be trusted by specifying an array of certificates:</p>
<pre lang="ini"><code>ca[]="..."
ca[]="..."
</code></pre>
<p>See also the <code>strict-ssl</code> config.</p>

<li>Default: null</li>
<li>Type: Path</li>
</ul>
<p>A path to a file containing one or multiple Certificate Authority signing
certificates. Similar to the <code>ca</code> setting, but allows for multiple CA's, as
well as for the CA information to be stored in a file on disk.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="call"><code>call</code></h4>
<ul>
<li>Default: ""</li>
<li>Type: String</li>
</ul>
<p>Optional companion option for <code>npm exec</code>, <code>npx</code> that allows for specifying a
custom command to be run along with the installed packages.</p>
<pre lang="bash"><code>npm exec --package yo --package generator-node --call "yo node"
</code></pre>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="cert"><code>cert</code></h4>
<ul>
<li>Default: null</li>

</ul>
<p>A client certificate to pass when accessing the registry. Values should be
in PEM format (Windows calls it "Base-64 encoded X.509 (.CER)") with
newlines replaced by the string "\n". For example:</p>
<pre lang="ini"><code>cert="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"
</code></pre>
<p>It is <em>not</em> the path to a certificate file, though you can set a
registry-scoped "certfile" path like
"//other-registry.tld/:certfile=/path/to/cert.pem".</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="ci-name"><code>ci-name</code></h4>

<ul>
<li>Default: true</li>

<!-- raw HTML omitted -->
<h4 id="global"><code>global</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Operates in "global" mode, so that packages are installed into the <code>prefix</code>
folder instead of the current working directory. See
<a href="../configuring-npm/folders.html">folders</a> for more on the differences in behavior.</p>
<ul>
<li>packages are installed into the <code>{prefix}/lib/node_modules</code> folder, instead
of the current working directory.</li>

<h4 id="global-style"><code>global-style</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Causes npm to install the package into your local <code>node_modules</code> folder with
the same layout it uses with the global <code>node_modules</code> folder. Only your
direct dependencies will show in <code>node_modules</code> and everything they depend
on will be flattened in their <code>node_modules</code> folders. This obviously will
eliminate some deduping. If used with <code>legacy-bundling</code>, <code>legacy-bundling</code>
will be preferred.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="globalconfig"><code>globalconfig</code></h4>
<ul>
<li>Default: The global --prefix setting plus 'etc/npmrc'. For example,
'/usr/local/etc/npmrc'</li>
<li>Type: Path</li>

</ul>
<p>A proxy to use for outgoing https requests. If the <code>HTTPS_PROXY</code> or
<code>https_proxy</code> or <code>HTTP_PROXY</code> or <code>http_proxy</code> environment variables are set,
proxy settings will be honored by the underlying <code>make-fetch-happen</code>
library.</p>

<!-- raw HTML omitted -->
<h4 id="if-present"><code>if-present</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>If true, npm will not exit with an error code when <code>run-script</code> is invoked
for a script that isn't defined in the <code>scripts</code> section of <code>package.json</code>.
This option can be used when it's desirable to optionally run a script when
it's present and fail if the script fails. This is useful, for example, when
running scripts that may only apply for some builds in an otherwise generic
CI setup.</p>
<p>This value is not exported to the environment for child processes.</p>

<!-- raw HTML omitted -->
<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-script</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="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="include-staged"><code>include-staged</code></h4>
<ul>
<li>Default: false</li>

<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>

<li>Default: "~/.npm-init.js"</li>
<li>Type: Path</li>
</ul>
<p>A module that will be loaded by the <code>npm init</code> command. See the
documentation for the

<h4 id="init-version"><code>init-version</code></h4>
<ul>
<li>Default: "1.0.0"</li>

<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 that exist outside of the project root
will be packed and installed as regular dependencies instead of creating a
symlink. This option has no effect on workspaces.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="json"><code>json</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Whether or not to output JSON data, rather than the normal output.</p>
<ul>
<li>In <code>npm pkg set</code> it enables parsing set values with JSON.parse() before
saving them to your <code>package.json</code>.</li>
</ul>
<p>Not supported by all npm commands.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="key"><code>key</code></h4>
<ul>
<li>Default: null</li>
<li>Type: null or String</li>
</ul>
<p>A client key to pass when accessing the registry. Values should be in PEM
format with newlines replaced by the string "\n". For example:</p>
<pre lang="ini"><code>key="-----BEGIN PRIVATE KEY-----\nXXXX\nXXXX\n-----END PRIVATE KEY-----"
</code></pre>
<p>It is <em>not</em> the path to a key file, though you can set a registry-scoped
"keyfile" path like "//other-registry.tld/:keyfile=/path/to/key.pem".</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="legacy-bundling"><code>legacy-bundling</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Causes npm to install the package such that versions of npm prior to 1.4,
such as the one included with node 0.8, can install the package. This
eliminates all automatic deduping. If used with <code>global-style</code> this option
will be preferred.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="legacy-peer-deps"><code>legacy-peer-deps</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Causes npm to completely ignore <code>peerDependencies</code> when building a package
tree, as in npm versions 3 through 6.</p>
<p>If a package cannot be installed because of overly strict <code>peerDependencies</code>
that collide, it provides a way to move forward resolving the situation.</p>
<p>This differs from <code>--omit=peer</code>, in that <code>--omit=peer</code> will avoid unpacking
<code>peerDependencies</code> on disk, but will still design a tree such that
<code>peerDependencies</code> <em>could</em> be unpacked in a correct place.</p>
<p>Use of <code>legacy-peer-deps</code> is not recommended, as it will not enforce the
<code>peerDependencies</code> contract that meta-dependencies may rely on.</p>

<!-- raw HTML omitted -->
<h4 id="link"><code>link</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>

<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="local-address"><code>local-address</code></h4>
<ul>
<li>Default: null</li>
<li>Type: IP Address</li>
</ul>
<p>The IP address of the local interface to use when making connections to the
npm registry. Must be IPv4 in versions of Node prior to 0.12.</p>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="location"><code>location</code></h4>
<ul>
<li>Default: "user" unless <code>--global</code> is passed, which will also set this value
to "global"</li>
<li>Type: "global", "user", or "project"</li>
</ul>
<p>When passed to <code>npm config</code> this refers to which config file to use.</p>
<p>When set to "global" mode, packages are installed into the <code>prefix</code> folder
instead of the current working directory. See
<a href="../configuring-npm/folders.html">folders</a> for more on the differences in behavior.</p>
<ul>
<li>packages are installed into the <code>{prefix}/lib/node_modules</code> folder, instead
of the current working directory.</li>
<li>bin files are linked to <code>{prefix}/bin</code></li>
<li>man pages are linked to <code>{prefix}/share/man</code></li>
</ul>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="lockfile-version"><code>lockfile-version</code></h4>
<ul>
<li>Default: Version 2 if no lockfile or current lockfile version less than or
equal to 2, otherwise maintain current lockfile version</li>
<li>Type: null, 1, 2, 3, "1", "2", or "3"</li>
</ul>
<p>Set the lockfile format version to be used in package-lock.json and
npm-shrinkwrap-json files. Possible options are:</p>
<p>1: The lockfile version used by npm versions 5 and 6. Lacks some data that
is used during the install, resulting in slower and possibly less
deterministic installs. Prevents lockfile churn when interoperating with
older npm versions.</p>
<p>2: The default lockfile version used by npm version 7. Includes both the
version 1 lockfile data and version 3 lockfile data, for maximum determinism
and interoperability, at the expense of more bytes on disk.</p>
<p>3: Only the new lockfile information introduced in npm version 7. Smaller on
disk than lockfile version 2, but not interoperable with older npm versions.
Ideal if all users are on npm version 7 and higher.</p>
