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>   <ul> <li><code>-a</code>: <code>--all</code></li> <li><code>--enjoy-by</code>: <code>--before</code></li> <li><code>-c</code>: <code>--call</code></li> <li><code>--desc</code>: <code>--description</code></li> <li><code>-f</code>: <code>--force</code></li> <li><code>-g</code>: <code>--global</code></li> <li><code>-d</code>: <code>--loglevel info</code></li> <li><code>-s</code>: <code>--loglevel silent</code></li> <li><code>--silent</code>: <code>--loglevel silent</code></li> <li><code>--ddd</code>: <code>--loglevel silly</code></li> <li><code>--dd</code>: <code>--loglevel verbose</code></li> <li><code>--verbose</code>: <code>--loglevel verbose</code></li> <li><code>-q</code>: <code>--loglevel warn</code></li> <li><code>--quiet</code>: <code>--loglevel warn</code></li> <li><code>-l</code>: <code>--long</code></li> <li><code>-m</code>: <code>--message</code></li> <li><code>--local</code>: <code>--no-global</code></li> <li><code>-n</code>: <code>--no-yes</code></li> <li><code>--no</code>: <code>--no-yes</code></li> <li><code>-p</code>: <code>--parseable</code></li> <li><code>--porcelain</code>: <code>--parseable</code></li> <li><code>-C</code>: <code>--prefix</code></li> <li><code>--readonly</code>: <code>--read-only</code></li> <li><code>--reg</code>: <code>--registry</code></li> <li><code>-S</code>: <code>--save</code></li> <li><code>-B</code>: <code>--save-bundle</code></li> <li><code>-D</code>: <code>--save-dev</code></li> <li><code>-E</code>: <code>--save-exact</code></li> <li><code>-O</code>: <code>--save-optional</code></li> <li><code>-P</code>: <code>--save-prod</code></li> <li><code>-?</code>: <code>--usage</code></li> <li><code>-h</code>: <code>--usage</code></li> <li><code>-H</code>: <code>--usage</code></li> <li><code>--help</code>: <code>--usage</code></li> <li><code>-v</code>: <code>--version</code></li> <li><code>-w</code>: <code>--workspace</code></li> <li><code>--ws</code>: <code>--workspaces</code></li> <li><code>-y</code>: <code>--yes</code></li> </ul>  <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> <h3 id="config-settings">Config Settings</h3>   <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.</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> <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> <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> <h4 id="allow-same-version"><code>allow-same-version</code></h4> <ul> <li>Default: false</li> <li>Type: Boolean</li> </ul> <p>Prevents throwing an error when <code>npm version</code> is used to set the new version to the same value as the current version.</p> <h4 id="always-auth"><code>always-auth</code></h4> <ul> <li>Default: false</li> <li>Type: Boolean</li> </ul> <p>Force npm to always require authentication when accessing the registry, even for <code>GET</code> requests.</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 <code>npm install</code> runs 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="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> <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> <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="browser"><code>browser</code></h4> <ul> <li>Default: OS X: <code>"open"</code>, Windows: <code>"start"</code>, Others: <code>"xdg-open"</code></li> <li>Type: null, Boolean, or String</li> </ul> <p>The browser that is called by npm commands to open websites.</p> <p>Set to <code>false</code> to suppress browser behavior and instead print urls to terminal.</p> <p>Set to <code>true</code> to use default system URL opener.</p> <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> <h4 id="cache"><code>cache</code></h4> <ul> <li>Default: Windows: <code>%LocalAppData%\npm-cache</code>, Posix: <code>~/.npm</code></li> <li>Type: Path</li> </ul> <p>The location of npm’s cache directory. See <a href="../commands/npm-cache.html"><code>npm cache</code></a></p> <h4 id="cafile"><code>cafile</code></h4> <ul> <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> <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> <h4 id="cert"><code>cert</code></h4> <ul> <li>Default: null</li> <li>Type: null or String</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 (and there is no “certfile” option).</p> <h4 id="ci-name"><code>ci-name</code></h4> <ul> <li>Default: The name of the current CI system, or <code>null</code> when not on a known CI platform.</li> <li>Type: null or String</li> </ul> <p>The name of a continuous integration system. If not set explicitly, npm will detect the current CI environment using the <a href="http://npm.im/@npmcli/ci-detect"><code>@npmcli/ci-detect</code></a> module.</p> <h4 id="cidr"><code>cidr</code></h4> <ul> <li>Default: null</li> <li>Type: null or String (can be set multiple times)</li> </ul> <p>This is a list of CIDR address to be used when configuring limited access tokens with the <code>npm token create</code> command.</p> <h4 id="color"><code>color</code></h4> <ul> <li>Default: true unless the NO_COLOR environ is set to something other than ‘0’</li> <li>Type: “always” or Boolean</li> </ul> <p>If false, never shows colors.
