npm configuration in general. To learn about the <code>config</code> command, see <a href="../commands/npm-config.html"><code>npm config</code></a>.</p> <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>--iwr</code>: <code>--include-workspace-root</code></li> <li><code>-L</code>: <code>--location</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><code class="language-bash">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><code class="language-bash">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. 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> <h4 id="access"><code>access</code></h4> <ul> <li>Default: 'public' for new packages, existing packages it will not change the current level</li> <li>Type: null, "restricted", or "public"</li> </ul> <p>If you do not want your scoped package to be publicly viewable (and installable) set <code>--access=restricted</code>.</p> <p>Unscoped packages can not be set to <code>restricted</code>.</p> <p>Note: This defaults to not changing the current access level for existing packages. Specifying a value of <code>restricted</code> or <code>public</code> during publish will change the access for an existing package the same way that <code>npm access set status</code> would.</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="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="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="auth-type"><code>auth-type</code></h4> <ul> <li>Default: "web"</li> <li>Type: "legacy" or "web"</li> </ul> <p>What authentication strategy to use with <code>login</code>. Note that if an <code>otp</code> config is given, this value will always be set to <code>legacy</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 given date are installed. If there are no versions available for the current set of 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: macOS: <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><code class="language-ini">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><code class="language-ini">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.</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><code class="language-bash">npm exec --package yo --package generator-node --call "yo node" </code></pre> <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. If <code>"always"</code> then always shows colors.

selector syntax</li> <li>Leverages existing, known language syntax & operators from CSS to make disparate package information broadly accessible</li> <li>Unlocks the ability to answer complex, multi-faceted questions about dependencies, their relationships & associative metadata</li> <li>Consolidates redundant logic of similar query commands in <code>npm</code> (ex. <code>npm fund</code>,

<li><code>:vuln(<selector>)</code> when a dependency has a known vulnerability</li> </ul> <h5 id="semverspec-selector-function"><code>:semver(<spec>, [selector], [function])</code></h5> <p>The <code>:semver()</code> pseudo selector allows comparing fields from each node's <code>package.json</code> using <a href="https://github.com/npm/node-semver#readme">semver</a> methods. It accepts up to 3 parameters, all but the first of which are optional.</p> <ul> <li><code>spec</code> a semver version or range</li> <li><code>selector</code> an attribute selector for each node (default <code>[version]</code>)</li> <li><code>function</code> a semver method to apply, one of: <code>satisfies</code>, <code>intersects</code>, <code>subset</code>, <code>gt</code>, <code>gte</code>, <code>gtr</code>, <code>lt</code>, <code>lte</code>, <code>ltr</code>, <code>eq</code>, <code>neq</code> or the special function <code>infer</code> (default <code>infer</code>)</li> </ul> <p>When the special <code>infer</code> function is used the <code>spec</code> and the actual value from the node are compared. If both are versions, according to <code>semver.valid()</code>, <code>eq</code> is used. If both values are ranges, according to <code>!semver.valid()</code>, <code>intersects</code> is used. If the values are mixed types <code>satisfies</code> is used.</p> <p>Some examples:</p> <ul> <li><code>:semver(^1.0.0)</code> returns every node that has a <code>version</code> satisfied by the provided range <code>^1.0.0</code></li> <li><code>:semver(16.0.0, :attr(engines, [node]))</code> returns every node which has an <code>engines.node</code> property satisfying the version <code>16.0.0</code></li> <li><code>:semver(1.0.0, [version], lt)</code> every node with a <code>version</code> less than <code>1.0.0</code></li> </ul> <h5 id="outdatedtype"><code>:outdated(<type>)</code></h5> <p>The <code>:outdated</code> pseudo selector retrieves data from the registry and returns information about which of your dependencies are outdated. The type parameter may be one of the following:</p> <ul> <li><code>any</code> (default) a version exists that is greater than the current one</li> <li><code>in-range</code> a version exists that is greater than the current one, and satisfies at least one if its parent's dependencies</li> <li><code>out-of-range</code> a version exists that is greater than the current one, does not satisfy at least one of its parent's dependencies</li> <li><code>major</code> a version exists that is a semver major greater than the current one</li> <li><code>minor</code> a version exists that is a semver minor greater than the current one</li> <li><code>patch</code> a version exists that is a semver patch greater than the current one</li> </ul> <p>In addition to the filtering performed by the pseudo selector, some extra data is added to the resulting objects. The following data can be found under the <code>queryContext</code> property of each node.</p> <ul> <li><code>versions</code> an array of every available version of the given node</li> <li><code>outdated.inRange</code> an array of objects, each with a <code>from</code> and <code>versions</code>, where <code>from</code> is the on-disk location of the node that depends on the current node and <code>versions</code> is an array of all available versions that satisfies that dependency. This is only populated if <code>:outdated(in-range)</code> is used.</li> <li><code>outdated.outOfRange</code> an array of objects, identical in shape to <code>inRange</code>, but where the <code>versions</code> array is every available version that does not satisfy the dependency. This is only populated if <code>:outdated(out-of-range)</code> is used.</li> </ul> <p>Some examples:</p> <ul> <li><code>:root > :outdated(major)</code> returns every direct dependency that has a new semver major release</li> <li><code>.prod:outdated(in-range)</code> returns production dependencies that have a new release that satisfies at least one of its parent's dependencies</li> </ul> <h5 id="vuln"><code>:vuln</code></h5> <p>The <code>:vuln</code> pseudo selector retrieves data from the registry and returns information about which if your dependencies has a known vulnerability. Only dependencies whose current version matches a vulnerability will be returned. For example if you have <code>semver@7.6.0</code> in your tree, a vulnerability for <code>semver</code> which affects versions <code><=6.3.1</code> will not match.</p> <p>You can also filter results by certain attributes in advisories. Currently that includes <code>severity</code> and <code>cwe</code>. Note that severity filtering is done per severity, it does not include severities "higher" or "lower" than the one specified.</p> <p>In addition to the filtering performed by the pseudo selector, info about each relevant advisory will be added to the <code>queryContext</code> attribute of each node under the <code>advisories</code> attribute.</p> <p>Some examples:</p> <ul> <li><code>:root > .prod:vuln</code> returns direct production dependencies with any known vulnerability</li> <li><code>:vuln([severity=high])</code> returns only dependencies with a vulnerability with a <code>high</code> severity.</li> <li><code>:vuln([severity=high],[severity=moderate])</code> returns only dependencies with a vulnerability with a <code>high</code> or <code>moderate</code> severity.</li> <li><code>:vuln([cwe=1333])</code> returns only dependencies with a vulnerability that includes CWE-1333 (ReDoS)</li> </ul> <h4 id="attribute-selectors"><a href="https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors">Attribute Selectors</a></h4> <p>The attribute selector evaluates the key/value pairs in <code>package.json</code> if they are <code>String</code>s.</p> <ul> <li><code>[]</code> attribute selector (ie. existence of attribute)</li> <li><code>[attribute=value]</code> attribute value is equivalent...</li> <li><code>[attribute~=value]</code> attribute value contains word...</li> <li><code>[attribute=value]</code> attribute value contains string...</li> <li><code>[attribute\|=value]</code> attribute value is equal to or starts with...</li> <li><code>[attribute^=value]</code> attribute value starts with...</li> <li><code>[attribute$=value]</code> attribute value ends with...</li> </ul> <h4 id="array--object-attribute-selectors"><code>Array</code> & <code>Object</code> Attribute Selectors</h4> <p>The generic <code>:attr()</code> pseudo selector standardizes a pattern which can be used for attribute selection of <code>Object</code>s, <code>Array</code>s or <code>Arrays</code> of <code>Object</code>s accessible via <code>Arborist</code>'s <code>Node.package</code> metadata. This allows for iterative attribute selection beyond top-level <code>String</code> evaluation. The last argument passed to <code>:attr()</code> must be an <code>attribute</code> selector or a nested <code>:attr()</code>. See examples below:</p> <h4 id="objects"><code>Objects</code></h4> <pre><code class="language-css">/* return dependencies that have a `scripts.test` containing `"tap"` / :attr(scripts, [test~=tap]) </code></pre> <h4 id="nested-objects">Nested <code>Objects</code></h4> <p>Nested objects are expressed as sequential arguments to <code>:attr()</code>.</p> <pre><code class="language-css">/* return dependencies that have a testling config for opera browsers / :attr(testling, browsers, [~=opera]) </code></pre> <h4 id="arrays"><code>Arrays</code></h4> <p><code>Array</code>s specifically uses a special/reserved <code>.</code> character in place of a typical attribute name. <code>Arrays</code> also support exact <code>value</code> matching when a <code>String</code> is passed to the selector.</p> <h5 id="example-of-an-array-attribute-selection">Example of an <code>Array</code> Attribute Selection:</h5> <pre><code class="language-css">/* removes the distinction between properties & arrays / / ie. we'd have to check the property & iterate to match selection / :attr([keywords^=react]) :attr(contributors, :attr([name~=Jordan])) </code></pre> <h5 id="example-of-an-array-matching-directly-to-a-value">Example of an <code>Array</code> matching directly to a value:</h5> <pre><code class="language-css">/ return dependencies that have the exact keyword "react" / / this is equivalent to `:keywords([value="react"])` / :attr([keywords=react]) </code></pre> <h5 id="example-of-an-array-of-objects">Example of an <code>Array</code> of <code>Object</code>s:</h5> <pre><code class="language-css">/ returns / :attr(contributors, [email=ruyadorno@github.com]) </code></pre> <h3 id="groups">Groups</h3> <p>Dependency groups are defined by the package relationships to their ancestors (ie. the dependency types that are defined in <code>package.json</code>). This approach is user-centric as the ecosystem has been taught to think about dependencies in these groups first-and-foremost. Dependencies are allowed to be included in multiple groups (ex. a <code>prod</code> dependency may also be a <code>dev</code> dependency (in that it's also required by another <code>dev</code> dependency) & may also be <code>bundled</code> - a selector for that type of dependency would look like: <code>*.prod.dev.bundled</code>).</p> <ul> <li><code>.prod</code></li> <li><code>.dev</code></li> <li><code>.optional</code></li> <li><code>.peer</code></li> <li><code>.bundled</code></li> <li><code>.workspace</code></li> </ul> <p>Please note that currently <code>workspace</code> deps are always <code>prod</code> dependencies.

The default is whatever the repository uses as its default branch.</p> <h3 id="the-packagejson-file">The package.json File</h3> <p>You need to have a <code>package.json</code> file in the root of your project to do much of anything with npm. That is basically the whole interface.</p> <p>See <a href="../configuring-npm/package-json.html"><code>package.json</code></a> for details about what goes in that file. At the very least, you need:</p> <ul> <li> <p>name: This should be a string that identifies your project. Please do not use the name to specify that it runs on node, or is in JavaScript. You can use the "engines" field to explicitly state the versions of node (or whatever else) that your program requires, and it's pretty well assumed that it's JavaScript.</p> <p>It does not necessarily need to match your github repository name.</p> <p>So, <code>node-foo</code> and <code>bar-js</code> are bad names. <code>foo</code> or <code>bar</code> are better.</p> </li> <li> <p>version: A semver-compatible version.</p> </li> <li> <p>engines: Specify the versions of node (or whatever else) that your program runs on. The node API changes a lot, and there may be bugs or new functionality that you depend on. Be explicit.</p> </li> <li> <p>author: Take some credit.</p> </li> <li> <p>scripts: If you have a special compilation or installation script, then you should put it in the <code>scripts</code> object. You should definitely have at least a basic smoke-test command as the "scripts.test" field. See <a href="../using-npm/scripts.html">scripts</a>.</p> </li> <li> <p>main: If you have a single module that serves as the entry point to your program (like what the "foo" package gives you at require("foo")), then you need to specify that in the "main" field.</p> </li> <li> <p>directories: This is an object mapping names to folders. The best ones to include are "lib" and "doc", but if you use "man" to specify a folder full of man pages, they'll get installed just like these ones.</p> </li> </ul> <p>You can use <code>npm init</code> in the root of your package in order to get you started with a pretty basic package.json file. See <a href="../commands/npm-init.html"><code>npm init</code></a> for more info.</p> <h3 id="keeping-files-out-of-your-package">Keeping files <em>out</em> of your Package</h3> <p>Use a <code>.npmignore</code> file to keep stuff out of your package. If there's no <code>.npmignore</code> file, but there <em>is</em> a <code>.gitignore</code> file, then npm will ignore the stuff matched by the <code>.gitignore</code> file. If you <em>want</em> to include something that is excluded by your <code>.gitignore</code> file, you can create an empty <code>.npmignore</code> file to override it. Like <code>git</code>, <code>npm</code> looks for <code>.npmignore</code> and <code>.gitignore</code> files in all subdirectories of your package, not only the root directory.</p> <p><code>.npmignore</code> files follow the <a href="https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository#_ignoring">same pattern rules</a> as <code>.gitignore</code> files:</p> <ul> <li>Blank lines or lines starting with <code>#</code> are ignored.</li> <li>Standard glob patterns work.</li> <li>You can end patterns with a forward slash <code>/</code> to specify a directory.</li> <li>You can negate a pattern by starting it with an exclamation point <code>!</code>.</li> </ul> <p>By default, some paths and files are ignored, so there's no need to add them to <code>.npmignore</code> explicitly. Some examples are:</p> <ul> <li><code>..swp</code></li> <li><code>._</code></li> <li><code>.DS_Store</code></li> <li><code>.git</code></li> <li><code>.gitignore</code></li> <li><code>.hg</code></li> <li><code>.npmignore</code></li> <li><code>.npmrc</code></li> <li><code>.lock-wscript</code></li> <li><code>.svn</code></li> <li><code>.wafpickle-*</code></li> <li><code>config.gypi</code></li> <li><code>CVS</code></li> <li><code>npm-debug.log</code></li> </ul> <p>Additionally, everything in <code>node_modules</code> is ignored, except for bundled dependencies. npm automatically handles this for you, so don't bother adding <code>node_modules</code> to <code>.npmignore</code>.</p> <p>The following paths and files are never ignored, so adding them to <code>.npmignore</code> is pointless:</p> <ul> <li><code>package.json</code></li> <li><code>README</code> (and its variants)</li> <li><code>LICENSE</code> / <code>LICENCE</code></li> </ul> <p>If, given the structure of your project, you find <code>.npmignore</code> to be a maintenance headache, you might instead try populating the <code>files</code> property of <code>package.json</code>, which is an array of file or directory names that should be included in your package. Sometimes manually picking which items to allow is easier to manage than building a block list.</p> <p>See <a href="../configuring-npm/package-json.html"><code>package.json</code></a> for more info on what can and can't be ignored.</p> <h4 id="testing-whether-your-npmignore-or-files-config-works">Testing whether your <code>.npmignore</code> or <code>files</code> config works</h4> <p>If you want to double check that your package will include only the files you intend it to when published, you can run the <code>npm pack</code> command locally which will generate a tarball in the working directory, the same way it does for publishing.</p> <h3 id="link-packages">Link Packages</h3> <p><code>npm link</code> is designed to install a development package and see the changes in real time without having to keep re-installing it. (You do need to either re-link or <code>npm rebuild -g</code> to update compiled packages, of course.)</p> <p>More info at <a href="../commands/npm-link.html"><code>npm link</code></a>.</p> <h3 id="before-publishing-make-sure-your-package-installs-and-works">Before Publishing: Make Sure Your Package Installs and Works</h3> <p><strong>This is important.</strong></p> <p>If you can not install it locally, you'll have problems trying to publish it. Or, worse yet, you'll be able to publish it, but you'll be publishing a broken or pointless package. So don't do that.</p> <p>In the root of your package, do this:</p> <pre><code class="language-bash">npm install . -g </code></pre> <p>That'll show you that it's working. If you'd rather just create a symlink package that points to your working directory, then do this:</p> <pre><code class="language-bash">npm link </code></pre> <p>Use <code>npm ls -g</code> to see if it's there.</p> <p>To test a local install, go into some other folder, and then do:</p> <pre><code class="language-bash">cd ../some-other-folder npm install ../my-package </code></pre> <p>to install it locally into the node_modules folder in that other place.</p> <p>Then go into the node-repl, and try using require("my-thing") to bring in your module's main module.</p> <h3 id="create-a-user-account">Create a User Account</h3> <p>Create a user with the adduser command. It works like this:</p> <pre><code class="language-bash">npm adduser </code></pre> <p>and then follow the prompts.</p> <p>This is documented better in <a href="../commands/npm-adduser.html">npm adduser</a>.</p> <h3 id="publish-your-package">Publish your Package</h3> <p>This part's easy. In the root of your folder, do this:</p> <pre><code class="language-bash">npm publish </code></pre> <p>You can give publish a url to a tarball, or a filename of a tarball, or a path to a folder.</p> <p>Note that pretty much <strong>everything in that folder will be exposed</strong> by default. So, if you have secret stuff in there, use a <code>.npmignore</code> file to list out the globs to ignore, or publish from a fresh checkout.</p> <h3 id="brag-about-it">Brag about it</h3> <p>Send emails, write blogs, blab in IRC.</p> <p>Tell the world how easy it is to install your program!</p> <h3 id="see-also">See also</h3> <ul> <li><a href="../commands/npm.html">npm</a></li> <li><a href="../commands/npm-init.html">npm init</a></li> <li><a href="../configuring-npm/package-json.html">package.json</a></li> <li><a href="../using-npm/scripts.html">npm scripts</a></li> <li><a href="../commands/npm-publish.html">npm publish</a></li> <li><a href="../commands/npm-adduser.html">npm adduser</a></li> <li><a href="../using-npm/registry.html">npm registry</a></li> </ul></div> <footer id="edit"> <a href="https://github.com/npm/cli/edit/latest/docs/lib/content/using-npm/developers.md"> <svg role="img" viewBox="0 0 16 16" width="16" height="16" fill="currentcolor" style="vertical-align: text-bottom; margin-right: 0.3em;"> <path fill-rule="evenodd" d="M11.013 1.427a1.75 1.75 0 012.474 0l1.086 1.086a1.75 1.75 0 010 2.474l-8.61 8.61c-.21.21-.47.364-.756.445l-3.251.93a.75.75 0 01-.927-.928l.929-3.25a1.75 1.75 0 01.445-.758l8.61-8.61zm1.414 1.06a.25.25 0 00-.354 0L10.811 3.75l1.439 1.44 1.263-1.263a.25.25 0 000-.354l-1.086-1.086zM11.189 6.25L9.75 4.81l-6.286 6.287a.25.25 0 00-.064.108l-.558 1.953 1.953-.558a.249.249 0 00.108-.064l6.286-6.286z"></path> </svg> Edit this page on GitHub </a> </footer> </section> </body></html>	14.42 KB	2025-08-25 15:00

This is typically used in combination with the <a href="../using-npm/config#registry.html">registry</a> config to refer to a package in a registry.</p> <p>Examples:</p> <ul> <li><code>npm</code></li> <li><code>@npmcli/arborist</code></li> <li><code>@npmcli/arborist@latest</code></li> <li><code>npm@6.13.1</code></li> <li><code>npm@^4.0.0</code></li> </ul> <h3 id="aliases">Aliases</h3> <ul> <li><code><alias>@npm:<name></code></li> </ul> <p>Primarily used by commands like <code>npm install</code> and in the dependency sections in the <code>package.json</code>, this refers to a package by an alias. The <code><alias></code> is the name of the package as it is reified in the <code>node_modules</code> folder, and the <code><name></code> refers to a package name as found in the configured registry.</p> <p>See <code>Package name</code> above for more info on referring to a package by name, and <a href="../using-npm/config#registry.html">registry</a> for configuring which registry is used when referring to a package by name.</p> <p>Examples:</p> <ul> <li><code>semver:@npm:@npmcli/semver-with-patch</code></li> <li><code>semver:@npm:semver@7.2.2</code></li> <li><code>semver:@npm:semver@legacy</code></li> </ul> <h3 id="folders">Folders</h3> <ul> <li><code><folder></code></li> </ul> <p>This refers to a package on the local filesystem. Specifically this is a folder with a <code>package.json</code> file in it. This <em>should</em> always be prefixed with a <code>/</code> or <code>./</code> (or your OS equivalent) to reduce confusion. npm currently will parse a string with more than one <code>/</code> in it as a folder, but this is legacy behavior that may be removed in a future version.</p> <p>Examples:</p> <ul> <li><code>./my-package</code></li> <li><code>/opt/npm/my-package</code></li> </ul> <h3 id="tarballs">Tarballs</h3> <ul> <li><code><tarball file></code></li> <li><code><tarball url></code></li> </ul> <p>Examples:</p> <ul> <li><code>./my-package.tgz</code></li> <li><code>https://registry.npmjs.org/semver/-/semver-1.0.0.tgz</code></li> </ul> <p>Refers to a package in a tarball format, either on the local filesystem or remotely via url. This is the format that packages exist in when uploaded to a registry.</p> <h3 id="git-urls">git urls</h3> <ul> <li><code><git:// url></code></li> <li><code><github username>/<github project></code></li> </ul> <p>Refers to a package in a git repo. This can be a full git url, git shorthand, or a username/package on GitHub.

Use of the npm public registry is subject to terms of use available at <a href="https://docs.npmjs.com/policies/terms">https://docs.npmjs.com/policies/terms</a>.</p> <p>You can configure npm to use any compatible registry you like, and even run your own registry. Use of someone else's registry may be governed by their terms of use.</p> <p>npm's package registry implementation supports several write APIs as well, to allow for publishing packages and managing user account information.</p> <p>The registry URL used is determined by the scope of the package (see <a href="../using-npm/scope.html"><code>scope</code></a>. If no scope is specified, the default registry is used, which is supplied by the <a href="../using-npm/config#registry.html"><code>registry</code> config</a> parameter. See <a href="../commands/npm-config.html"><code>npm config</code></a>, <a href="../configuring-npm/npmrc.html"><code>npmrc</code></a>, and <a href="../using-npm/config.html"><code>config</code></a> for more on managing npm's configuration. Authentication configuration such as auth tokens and certificates are configured specifically scoped to an individual registry. See <a href="../configuring-npm/npmrc#auth-related-configuration.html">Auth Related Configuration</a></p> <p>When the default registry is used in a package-lock or shrinkwrap it has the special meaning of "the currently configured registry". If you create a lock file while using the default registry you can switch to another registry and npm will install packages from the new registry, but if you create a lock file while using a custom registry packages will be installed from that registry even after you change to another registry.</p> <h3 id="does-npm-send-any-information-about-me-back-to-the-registry">Does npm send any information about me back to the registry?</h3> <p>Yes.</p> <p>When making requests of the registry npm adds two headers with information about your environment:</p> <ul> <li><code>Npm-Scope</code> – If your project is scoped, this header will contain its scope. In the future npm hopes to build registry features that use this information to allow you to customize your experience for your organization.</li> <li><code>Npm-In-CI</code> – Set to "true" if npm believes this install is running in a continuous integration environment, "false" otherwise. This is detected by looking for the following environment variables: <code>CI</code>, <code>TDDIUM</code>, <code>JENKINS_URL</code>, <code>bamboo.buildKey</code>.

Delete that folder, and everything is gone unless a package's install script is particularly ill-behaved.</p> <p>This assumes that you installed node and npm in the default place.

This can help find any symlinks that are lying around:</p> <pre><code class="language-bash">ls -laF /usr/local/{lib/node{,/.npm},bin,share/man} \| grep npm </code></pre> <p>Prior to version 0.3, npm used shim files for executables and node modules.

Some package names also have a scope. A scope follows the usual rules for package names (URL-safe characters, no leading dots or underscores). When used in package names, scopes are preceded by an <code>@</code> symbol and followed by a slash, e.g.</p> <pre><code class="language-bash">@somescope/somepackagename </code></pre> <p>Scopes are a way of grouping related packages together, and also affect a few things about the way npm treats the package.</p> <p>Each npm user/organization has their own scope, and only you can add packages in your scope. This means you don't have to worry about someone taking your package name ahead of you. Thus it is also a good way to signal official packages for organizations.</p> <p>Scoped packages can be published and installed as of <code>npm@2</code> and are supported by the primary npm registry. Unscoped packages can depend on scoped packages and vice versa. The npm client is backwards-compatible with unscoped registries, so it can be used to work with scoped and unscoped registries at the same time.</p> <h3 id="installing-scoped-packages">Installing scoped packages</h3> <p>Scoped packages are installed to a sub-folder of the regular installation folder, e.g. if your other packages are installed in <code>node_modules/packagename</code>, scoped modules will be installed in <code>node_modules/@myorg/packagename</code>. The scope folder (<code>@myorg</code>) is simply the name of the scope preceded by an <code>@</code> symbol, and can contain any number of scoped packages.</p> <p>A scoped package is installed by referencing it by name, preceded by an <code>@</code> symbol, in <code>npm install</code>:</p> <pre><code class="language-bash">npm install @myorg/mypackage </code></pre> <p>Or in <code>package.json</code>:</p> <pre><code class="language-json">"dependencies": { "@myorg/mypackage": "^1.3.0" } </code></pre> <p>Note that if the <code>@</code> symbol is omitted, in either case, npm will instead attempt to install from GitHub; see <a href="../commands/npm-install.html"><code>npm install</code></a>.</p> <h3 id="requiring-scoped-packages">Requiring scoped packages</h3> <p>Because scoped packages are installed into a scope folder, you have to include the name of the scope when requiring them in your code, e.g.</p> <pre><code class="language-javascript">require('@myorg/mypackage') </code></pre> <p>There is nothing special about the way Node treats scope folders. This simply requires the <code>mypackage</code> module in the folder named <code>@myorg</code>.</p> <h3 id="publishing-scoped-packages">Publishing scoped packages</h3> <p>Scoped packages can be published from the CLI as of <code>npm@2</code> and can be published to any registry that supports them, including the primary npm registry.</p> <p>(As of 2015-04-19, and with npm 2.0 or better, the primary npm registry <strong>does</strong> support scoped packages.)</p> <p>If you wish, you may associate a scope with a registry; see below.</p> <h4 id="publishing-public-scoped-packages-to-the-primary-npm-registry">Publishing public scoped packages to the primary npm registry</h4> <p>Publishing to a scope, you have two options:</p> <ul> <li>Publishing to your user scope (example: <code>@username/module</code>)</li> <li>Publishing to an organization scope (example: <code>@org/module</code>)</li> </ul> <p>If publishing a public module to an organization scope, you must first either create an organization with the name of the scope that you'd like to publish to or be added to an existing organization with the appropriate permissions. For example, if you'd like to publish to <code>@org</code>, you would need to create the <code>org</code> organization on npmjs.com prior to trying to publish.</p> <p>Scoped packages are not public by default. You will need to specify <code>--access public</code> with the initial <code>npm publish</code> command. This will publish the package and set access to <code>public</code> as if you had run <code>npm access public</code> after publishing. You do not need to do this when publishing new versions of an existing scoped package.</p> <h4 id="publishing-private-scoped-packages-to-the-npm-registry">Publishing private scoped packages to the npm registry</h4> <p>To publish a private scoped package to the npm registry, you must have an <a href="https://docs.npmjs.com/private-modules/intro">npm Private Modules</a> account.</p> <p>You can then publish the module with <code>npm publish</code> or <code>npm publish --access restricted</code>, and it will be present in the npm registry, with restricted access. You can then change the access permissions, if desired, with <code>npm access</code> or on the npmjs.com website.</p> <h3 id="associating-a-scope-with-a-registry">Associating a scope with a registry</h3> <p>Scopes can be associated with a separate registry. This allows you to seamlessly use a mix of packages from the primary npm registry and one or more private registries, such as <a href="https://github.com/features/packages">GitHub Packages</a> or the open source <a href="https://verdaccio.org">Verdaccio</a> project.</p> <p>You can associate a scope with a registry at login, e.g.</p> <pre><code class="language-bash">npm login --registry=http://reg.example.com --scope=@myco </code></pre> <p>Scopes have a many-to-one relationship with registries: one registry can host multiple scopes, but a scope only ever points to one registry.</p> <p>You can also associate a scope with a registry using <code>npm config</code>:</p> <pre><code class="language-bash">npm config set @myco:registry=http://reg.example.com </code></pre> <p>Once a scope is associated with a registry, any <code>npm install</code> for a package with that scope will request packages from that registry instead. Any <code>npm publish</code> for a package name that contains the scope will be published to that registry instead.</p> <h3 id="see-also">See also</h3> <ul> <li><a href="../commands/npm-install.html">npm install</a></li> <li><a href="../commands/npm-publish.html">npm publish</a></li> <li><a href="../commands/npm-access.html">npm access</a></li> <li><a href="../using-npm/registry.html">npm registry</a></li> </ul></div> <footer id="edit"> <a href="https://github.com/npm/cli/edit/latest/docs/lib/content/using-npm/scope.md"> <svg role="img" viewBox="0 0 16 16" width="16" height="16" fill="currentcolor" style="vertical-align: text-bottom; margin-right: 0.3em;"> <path fill-rule="evenodd" d="M11.013 1.427a1.75 1.75 0 012.474 0l1.086 1.086a1.75 1.75 0 010 2.474l-8.61 8.61c-.21.21-.47.364-.756.445l-3.251.93a.75.75 0 01-.927-.928l.929-3.25a1.75 1.75 0 01.445-.758l8.61-8.61zm1.414 1.06a.25.25 0 00-.354 0L10.811 3.75l1.439 1.44 1.263-1.263a.25.25 0 000-.354l-1.086-1.086zM11.189 6.25L9.75 4.81l-6.286 6.287a.25.25 0 00-.064.108l-.558 1.953 1.953-.558a.249.249 0 00.108-.064l6.286-6.286z"></path> </svg> Edit this page on GitHub </a> </footer> </section> </body></html>	10.42 KB	2025-08-25 15:00

These all can be executed by running <code>npm run <stage></code>. <em>Pre</em> and <em>post</em> commands with matching names will be run for those as well (e.g. <code>premyscript</code>, <code>myscript</code>, <code>postmyscript</code>).

It has also turned out to be, in practice, <a href="https://github.com/npm/npm/issues/10074">very confusing</a>. As of <code>npm@4.0.0</code>, a new event has been introduced, <code>prepare</code>, that preserves this existing behavior. A <em>new</em> event, <code>prepublishOnly</code> has been added as a transitional strategy to allow users to avoid the confusing behavior of existing npm versions and only run on <code>npm publish</code> (for instance, running the tests one last time to ensure they're in good shape).</p> <p>See <a href="https://github.com/npm/npm/issues/10074">https://github.com/npm/npm/issues/10074</a> for a much lengthier justification, with further reading, for this change.</p> <p><strong>Use Cases</strong></p> <p>If you need to perform operations on your package before it is used, in a way that is not dependent on the operating system or architecture of the target system, use a <code>prepublish</code> script. This includes tasks such as:</p> <ul> <li>Compiling CoffeeScript source code into JavaScript.</li> <li>Creating minified versions of JavaScript source code.</li> <li>Fetching remote resources that your package will use.</li> </ul> <p>The advantage of doing these things at <code>prepublish</code> time is that they can be done once, in a single place, thus reducing complexity and variability. Additionally, this means that:</p> <ul> <li>You can depend on <code>coffee-script</code> as a <code>devDependency</code>, and thus your users don't need to have it installed.</li> <li>You don't need to include minifiers in your package, reducing the size for your users.</li> <li>You don't need to rely on your users having <code>curl</code> or <code>wget</code> or other system tools on the target machines.</li> </ul> <h4 id="dependencies">Dependencies</h4> <p>The <code>dependencies</code> script is run any time an <code>npm</code> command causes changes to the <code>node_modules</code> directory. It is run AFTER the changes have been applied and the <code>package.json</code> and <code>package-lock.json</code> files have been updated.</p> <h3 id="life-cycle-operation-order">Life Cycle Operation Order</h3> <h4 id="npm-cache-add"><a href="../commands/npm-cache.html"><code>npm cache add</code></a></h4> <ul> <li><code>prepare</code></li> </ul> <h4 id="npm-ci"><a href="../commands/npm-ci.html"><code>npm ci</code></a></h4> <ul> <li><code>preinstall</code></li> <li><code>install</code></li> <li><code>postinstall</code></li> <li><code>prepublish</code></li> <li><code>preprepare</code></li> <li><code>prepare</code></li> <li><code>postprepare</code></li> </ul> <p>These all run after the actual installation of modules into <code>node_modules</code>, in order, with no internal actions happening in between</p> <h4 id="npm-diff"><a href="../commands/npm-diff.html"><code>npm diff</code></a></h4> <ul> <li><code>prepare</code></li> </ul> <h4 id="npm-install"><a href="../commands/npm-install.html"><code>npm install</code></a></h4> <p>These also run when you run <code>npm install -g <pkg-name></code></p> <ul> <li><code>preinstall</code></li> <li><code>install</code></li> <li><code>postinstall</code></li> <li><code>prepublish</code></li> <li><code>preprepare</code></li> <li><code>prepare</code></li> <li><code>postprepare</code></li> </ul> <p>If there is a <code>binding.gyp</code> file in the root of your package and you haven't defined your own <code>install</code> or <code>preinstall</code> scripts, npm will default the <code>install</code> command to compile using node-gyp via <code>node-gyp rebuild</code></p> <p>These are run from the scripts of <code><pkg-name></code></p> <h4 id="npm-pack"><a href="../commands/npm-pack.html"><code>npm pack</code></a></h4> <ul> <li><code>prepack</code></li> <li><code>prepare</code></li> <li><code>postpack</code></li> </ul> <h4 id="npm-publish"><a href="../commands/npm-publish.html"><code>npm publish</code></a></h4> <ul> <li><code>prepublishOnly</code></li> <li><code>prepack</code></li> <li><code>prepare</code></li> <li><code>postpack</code></li> <li><code>publish</code></li> <li><code>postpublish</code></li> </ul> <h4 id="npm-rebuild"><a href="../commands/npm-rebuild.html"><code>npm rebuild</code></a></h4> <ul> <li><code>preinstall</code></li> <li><code>install</code></li> <li><code>postinstall</code></li> <li><code>prepare</code></li> </ul> <p><code>prepare</code> is only run if the current directory is a symlink (e.g. with linked packages)</p> <h4 id="npm-restart"><a href="../commands/npm-restart.html"><code>npm restart</code></a></h4> <p>If there is a <code>restart</code> script defined, these events are run, otherwise <code>stop</code> and <code>start</code> are both run if present, including their <code>pre</code> and <code>post</code> iterations)</p> <ul> <li><code>prerestart</code></li> <li><code>restart</code></li> <li><code>postrestart</code></li> </ul> <h4 id="npm-run-user-defined"><a href="../commands/npm-run.html"><code>npm run <user defined></code></a></h4> <ul> <li><code>pre<user-defined></code></li> <li><code><user-defined></code></li> <li><code>post<user-defined></code></li> </ul> <h4 id="npm-start"><a href="../commands/npm-start.html"><code>npm start</code></a></h4> <ul> <li><code>prestart</code></li> <li><code>start</code></li> <li><code>poststart</code></li> </ul> <p>If there is a <code>server.js</code> file in the root of your package, then npm will default the <code>start</code> command to <code>node server.js</code>. <code>prestart</code> and <code>poststart</code> will still run in this case.</p> <h4 id="npm-stop"><a href="../commands/npm-stop.html"><code>npm stop</code></a></h4> <ul> <li><code>prestop</code></li> <li><code>stop</code></li> <li><code>poststop</code></li> </ul> <h4 id="npm-test"><a href="../commands/npm-test.html"><code>npm test</code></a></h4> <ul> <li><code>pretest</code></li> <li><code>test</code></li> <li><code>posttest</code></li> </ul> <h4 id="npm-version"><a href="../commands/npm-version.html"><code>npm version</code></a></h4> <ul> <li><code>preversion</code></li> <li><code>version</code></li> <li><code>postversion</code></li> </ul> <h4 id="a-note-on-a-lack-of-npm-uninstall-scripts">A Note on a lack of <a href="../commands/npm-uninstall.html"><code>npm uninstall</code></a> scripts</h4> <p>While npm v6 had <code>uninstall</code> lifecycle scripts, npm v7 does not. Removal of a package can happen for a wide variety of reasons, and there's no clear way to currently give the script enough context to be useful.</p> <p>Reasons for a package removal include:</p> <ul> <li>a user directly uninstalled this package</li> <li>a user uninstalled a dependant package and so this dependency is being uninstalled</li> <li>a user uninstalled a dependant package but another package also depends on this version</li> <li>this version has been merged as a duplicate with another version</li> <li>etc.</li> </ul> <p>Due to the lack of necessary context, <code>uninstall</code> lifecycle scripts are not implemented and will not function.</p> <h3 id="working-directory-for-scripts">Working Directory for Scripts</h3> <p>Scripts are always run from the root of the package folder, regardless of what the current working directory is when <code>npm</code> is invoked. This means your scripts can reliably assume they are running in the package root.</p> <p>If you want your script to behave differently based on the directory you were in when you ran <code>npm</code>, you can use the <code>INIT_CWD</code> environment variable, which holds the full path you were in when you ran <code>npm run</code>.</p> <h4 id="historical-behavior-in-older-npm-versions">Historical Behavior in Older npm Versions</h4> <p>For npm v6 and earlier, scripts were generally run from the root of the package, but there were rare cases and bugs in older versions where this was not guaranteed. If your package must support very old npm versions, you may wish to add a safeguard in your scripts (for example, by checking process.cwd()).</p> <p>For more details, see:</p> <ul> <li><a href="https://github.com/npm/cli/releases/tag/v7.0.0">npm v7 release notes</a></li> <li><a href="https://github.com/npm/npm/issues/12356">Discussion about script working directory reliability in npm v6 and earlier</a></li> </ul> <h3 id="user">User</h3> <p>When npm is run as root, scripts are always run with the effective uid and gid of the working directory owner.</p> <h3 id="environment">Environment</h3> <p>Package scripts run in an environment where many pieces of information are made available regarding the setup of npm and the current state of the process.</p> <h4 id="path">path</h4> <p>If you depend on modules that define executable scripts, like test suites, then those executables will be added to the <code>PATH</code> for executing the scripts. So, if your package.json has this:</p> <pre><code class="language-json">{ "name" : "foo", "dependencies" : { "bar" : "0.1.x" }, "scripts": { "start" : "bar ./test" } } </code></pre> <p>then you could run <code>npm start</code> to execute the <code>bar</code> script, which is exported into the <code>node_modules/.bin</code> directory on <code>npm install</code>.</p> <h4 id="packagejson-vars">package.json vars</h4> <p>The package.json fields are tacked onto the <code>npm_package_</code> prefix. So, for instance, if you had <code>{"name":"foo", "version":"1.2.5"}</code> in your package.json file, then your package scripts would have the <code>npm_package_name</code> environment variable set to "foo", and the <code>npm_package_version</code> set to "1.2.5". You can access these variables in your code with <code>process.env.npm_package_name</code> and <code>process.env.npm_package_version</code>, and so on for other fields.</p> <p>See <a href="../configuring-npm/package-json.html"><code>package.json</code></a> for more on package configs.</p> <h4 id="current-lifecycle-event">current lifecycle event</h4> <p>Lastly, the <code>npm_lifecycle_event</code> environment variable is set to whichever stage of the cycle is being executed. So, you could have a single script used for different parts of the process which switches based on what's currently happening.</p> <p>Objects are flattened following this format, so if you had <code>{"scripts":{"install":"foo.js"}}</code> in your package.json, then you'd see this in the script:</p> <pre><code class="language-bash">process.env.npm_package_scripts_install === "foo.js" </code></pre> <h3 id="examples">Examples</h3> <p>For example, if your package.json contains this:</p> <pre><code class="language-json">{ "scripts" : { "install" : "scripts/install.js", "postinstall" : "scripts/install.js" } } </code></pre> <p>then <code>scripts/install.js</code> will be called for the install and post-install stages of the lifecycle. Since <code>scripts/install.js</code> is running for two different phases, it would be wise in this case to look at the <code>npm_lifecycle_event</code> environment variable.</p> <p>If you want to run a make command, you can do so. This works just fine:</p> <pre><code class="language-json">{ "scripts" : { "preinstall" : "./configure", "install" : "make && make install", "test" : "make test" } } </code></pre> <h3 id="exiting">Exiting</h3> <p>Scripts are run by passing the line as a script argument to <code>/bin/sh</code> on POSIX systems or <code>cmd.exe</code> on Windows. You can control which shell is used by setting the <a href="../using-npm/config#script-shell.html"><code>script-shell</code></a> configuration option.</p> <p>If the script exits with a code other than 0, then this will abort the process.</p> <p>Note that these script files don't have to be Node.js or even JavaScript programs. They just have to be some kind of executable file.</p> <h3 id="best-practices">Best Practices</h3> <ul> <li>Don't exit with a non-zero error code unless you <em>really</em> mean it. If the failure is minor or only will prevent some optional features, then it's better to just print a warning and exit successfully.</li> <li>Try not to use scripts to do what npm can do for you. Read through <a href="../configuring-npm/package-json.html"><code>package.json</code></a> to see all the things that you can specify and enable by simply describing your package appropriately. In general, this will lead to a more robust and consistent state.</li> <li>Inspect the env to determine where to put things. For instance, if the <code>npm_config_binroot</code> environment variable is set to <code>/home/user/bin</code>, then don't try to install executables into <code>/usr/local/bin</code>. The user probably set it up that way for a reason.</li> <li>Don't prefix your script commands with "sudo". If root permissions are required for some reason, then it'll fail with that error, and the user will sudo the npm command in question.</li> <li>Don't use <code>install</code>. Use a <code>.gyp</code> file for compilation, and <code>prepare</code> for anything else. You should almost never have to explicitly set a preinstall or install script. If you are doing this, please consider if there is another option.

It automates the linking process as part of <code>npm install</code> and removes the need to manually use <code>npm link</code> in order to add references to packages that should be symlinked into the current <code>node_modules</code> folder.</p> <p>We also refer to these packages being auto-symlinked during <code>npm install</code> as a single <strong>workspace</strong>, meaning it's a nested package within the current local file system that is explicitly defined in the <a href="../configuring-npm/package-json#workspaces.html"><code>package.json</code></a> <code>workspaces</code> configuration.</p> <h3 id="defining-workspaces">Defining workspaces</h3> <p>Workspaces are usually defined via the <code>workspaces</code> property of the <a href="../configuring-npm/package-json#workspaces.html"><code>package.json</code></a> file, e.g:</p> <pre><code class="language-json">{ "name": "my-workspaces-powered-project", "workspaces": [ "packages/a" ] } </code></pre> <p>Given the above <code>package.json</code> example living at a current working directory <code>.</code> that contains a folder named <code>packages/a</code> that itself contains a <code>package.json</code> inside it, defining a Node.js package, e.g:</p> <pre><code>. +-- package.json `-- packages +-- a \| `-- package.json </code></pre> <p>The expected result once running <code>npm install</code> in this current working directory <code>.</code> is that the folder <code>packages/a</code> will get symlinked to the <code>node_modules</code> folder of the current working dir.</p> <p>Below is a post <code>npm install</code> example, given that same previous example structure of files and folders:</p> <pre><code>. +-- node_modules \| `-- a -> ../packages/a +-- package-lock.json +-- package.json `-- packages +-- a \| `-- package.json </code></pre> <h3 id="getting-started-with-workspaces">Getting started with workspaces</h3> <p>You may automate the required steps to define a new workspace using <a href="../commands/npm-init.html">npm init</a>. For example in a project that already has a <code>package.json</code> defined you can run:</p> <pre><code>npm init -w ./packages/a </code></pre> <p>This command will create the missing folders and a new <code>package.json</code> file (if needed) while also making sure to properly configure the <code>"workspaces"</code> property of your root project <code>package.json</code>.</p> <h3 id="adding-dependencies-to-a-workspace">Adding dependencies to a workspace</h3> <p>It's possible to directly add/remove/update dependencies of your workspaces using the <a href="../using-npm/config#workspace.html"><code>workspace</code> config</a>.</p> <p>For example, assuming the following structure:</p> <pre><code>. +-- package.json `-- packages +-- a \| `-- package.json `-- b `-- package.json </code></pre> <p>If you want to add a dependency named <code>abbrev</code> from the registry as a dependency of your workspace <strong>a</strong>, you may use the workspace config to tell the npm installer that package should be added as a dependency of the provided workspace:</p> <pre><code>npm install abbrev -w a </code></pre> <p>Note: other installing commands such as <code>uninstall</code>, <code>ci</code>, etc will also respect the provided <code>workspace</code> configuration.</p> <h3 id="using-workspaces">Using workspaces</h3> <p>Given the <a href="https://nodejs.org/dist/latest-v14.x/docs/api/modules.html#modules_all_together">specifics of how Node.js handles module resolution</a> it's possible to consume any defined workspace by its declared <code>package.json</code> <code>name</code>. Continuing from the example defined above, let's also create a Node.js script that will require the workspace <code>a</code> example module, e.g:</p> <pre><code>// ./packages/a/index.js module.exports = 'a' // ./lib/index.js const moduleA = require('a') console.log(moduleA) // -> a </code></pre> <p>When running it with:</p> <p><code>node lib/index.js</code></p> <p>This demonstrates how the nature of <code>node_modules</code> resolution allows for <strong>workspaces</strong> to enable a portable workflow for requiring each <strong>workspace</strong> in such a way that is also easy to <a href="../commands/npm-publish.html">publish</a> these nested workspaces to be consumed elsewhere.</p> <h3 id="running-commands-in-the-context-of-workspaces">Running commands in the context of workspaces</h3> <p>You can use the <code>workspace</code> configuration option to run commands in the context of a configured workspace. Additionally, if your current directory is in a workspace, the <code>workspace</code> configuration is implicitly set, and <code>prefix</code> is set to the root workspace.</p> <p>Following is a quick example on how to use the <code>npm run</code> command in the context of nested workspaces. For a project containing multiple workspaces, e.g:</p> <pre><code>. +-- package.json `-- packages +-- a \| `-- package.json `-- b `-- package.json </code></pre> <p>By running a command using the <code>workspace</code> option, it's possible to run the given command in the context of that specific workspace. e.g:</p> <pre><code>npm run test --workspace=a </code></pre> <p>You could also run the command within the workspace.</p> <pre><code>cd packages/a && npm run test </code></pre> <p>Either will run the <code>test</code> script defined within the <code>./packages/a/package.json</code> file.</p> <p>Please note that you can also specify this argument multiple times in the command-line in order to target multiple workspaces, e.g:</p> <pre><code>npm run test --workspace=a --workspace=b </code></pre> <p>Or run the command for each workspace within the 'packages' folder:</p> <pre><code>npm run test --workspace=packages </code></pre> <p>It's also possible to use the <code>workspaces</code> (plural) configuration option to enable the same behavior but running that command in the context of <strong>all</strong> configured workspaces. e.g:</p> <pre><code>npm run test --workspaces </code></pre> <p>Will run the <code>test</code> script in both <code>./packages/a</code> and <code>./packages/b</code>.</p> <p>Commands will be run in each workspace in the order they appear in your <code>package.json</code></p> <pre><code>{ "workspaces": [ "packages/a", "packages/b" ] } </code></pre> <p>Order of run is different with:</p> <pre><code>{ "workspaces": [ "packages/b", "packages/a" ] } </code></pre> <h3 id="ignoring-missing-scripts">Ignoring missing scripts</h3> <p>It is not required for all of the workspaces to implement scripts run with the <code>npm run</code> command.</p> <p>By running the command with the <code>--if-present</code> flag, npm will ignore workspaces missing target script.</p> <pre><code>npm run test --workspaces --if-present </code></pre> <h3 id="see-also">See also</h3> <ul> <li><a href="../commands/npm-install.html">npm install</a></li> <li><a href="../commands/npm-publish.html">npm publish</a></li> <li><a href="../commands/npm-run.html">npm run</a></li> <li><a href="../using-npm/config.html">config</a></li> </ul></div> <footer id="edit"> <a href="https://github.com/npm/cli/edit/latest/docs/lib/content/using-npm/workspaces.md"> <svg role="img" viewBox="0 0 16 16" width="16" height="16" fill="currentcolor" style="vertical-align: text-bottom; margin-right: 0.3em;"> <path fill-rule="evenodd" d="M11.013 1.427a1.75 1.75 0 012.474 0l1.086 1.086a1.75 1.75 0 010 2.474l-8.61 8.61c-.21.21-.47.364-.756.445l-3.251.93a.75.75 0 01-.927-.928l.929-3.25a1.75 1.75 0 01.445-.758l8.61-8.61zm1.414 1.06a.25.25 0 00-.354 0L10.811 3.75l1.439 1.44 1.263-1.263a.25.25 0 000-.354l-1.086-1.086zM11.189 6.25L9.75 4.81l-6.286 6.287a.25.25 0 00-.064.108l-.558 1.953 1.953-.558a.249.249 0 00.108-.064l6.286-6.286z"></path> </svg> Edit this page on GitHub </a> </footer> </section> </body></html>	11.58 KB	2025-08-25 15:00
