That's its job.</p> -<p>This document will tell you what it puts where.</p> -<h3 id="tldr">tl;dr</h3> -<ul> -<li>Local install (default): puts stuff in <code>./node_modules</code> of the current -package root.</li> -<li>Global install (with <code>-g</code>): puts stuff in /usr/local or wherever node -is installed.</li> -<li>Install it <strong>locally</strong> if you're going to <code>require()</code> it.</li> -<li>Install it <strong>globally</strong> if you're going to run it on the command line.</li> -<li>If you need both, then install it in both places, or use <code>npm link</code>.</li> -</ul> -<h3 id="prefix-configuration">prefix Configuration</h3> -<p>The <code>prefix</code> config defaults to the location where node is installed. -On most systems, this is <code>/usr/local</code>. On Windows, it's <code>%AppData%\npm</code>. -On Unix systems, it's one level up, since node is typically installed at -<code>{prefix}/bin/node</code> rather than <code>{prefix}/node.exe</code>.</p> -<p>When the <code>global</code> flag is set, npm installs things into this prefix. -When it is not set, it uses the root of the current package, or the -current working directory if not in a package already.</p> -<h3 id="node-modules">Node Modules</h3> -<p>Packages are dropped into the <code>node_modules</code> folder under the <code>prefix</code>. -When installing locally, this means that you can -<code>require("packagename")</code> to load its main module, or -<code>require("packagename/lib/path/to/sub/module")</code> to load other modules.</p> -<p>Global installs on Unix systems go to <code>{prefix}/lib/node_modules</code>. -Global installs on Windows go to <code>{prefix}/node_modules</code> (that is, no -<code>lib</code> folder.)</p> -<p>Scoped packages are installed the same way, except they are grouped together -in a sub-folder of the relevant <code>node_modules</code> folder with the name of that -scope prefix by the @ symbol, e.g. <code>npm install @myorg/package</code> would place -the package in <code>{prefix}/node_modules/@myorg/package</code>. See <code><a href="../misc/scope.html">scope(7)</a></code> for -more details.</p> -<p>If you wish to <code>require()</code> a package, then install it locally.</p> -<h3 id="executables">Executables</h3> -<p>When in global mode, executables are linked into <code>{prefix}/bin</code> on Unix, -or directly into <code>{prefix}</code> on Windows.</p> -<p>When in local mode, executables are linked into -<code>./node_modules/.bin</code> so that they can be made available to scripts run -through npm. (For example, so that a test runner will be in the path -when you run <code>npm test</code>.)</p> -<h3 id="man-pages">Man Pages</h3> -<p>When in global mode, man pages are linked into <code>{prefix}/share/man</code>.</p> -<p>When in local mode, man pages are not installed.</p> -<p>Man pages are not installed on Windows systems.</p> -<h3 id="cache">Cache</h3> -<p>See <code><a href="../cli/npm-cache.html">npm-cache(1)</a></code>. Cache files are stored in <code>~/.npm</code> on Posix, or -<code>%AppData%/npm-cache</code> on Windows.</p> -<p>This is controlled by the <code>cache</code> configuration param.</p> -<h3 id="temp-files">Temp Files</h3> -<p>Temporary files are stored by default in the folder specified by the -<code>tmp</code> config, which defaults to the TMPDIR, TMP, or TEMP environment -variables, or <code>/tmp</code> on Unix and <code>c:\windows\temp</code> on Windows.</p> -<p>Temp files are given a unique folder under this root for each run of the -program, and are deleted upon successful exit.</p> -<h2 id="more-information">More Information</h2> -<p>When installing locally, npm first tries to find an appropriate -<code>prefix</code> folder. This is so that <code>npm install foo@1.2.3</code> will install -to the sensible root of your package, even if you happen to have <code>cd</code>ed -into some other folder.</p> -<p>Starting at the $PWD, npm will walk up the folder tree checking for a -folder that contains either a <code>package.json</code> file, or a <code>node_modules</code> -folder. If such a thing is found, then that is treated as the effective -"current directory" for the purpose of running npm commands. (This -behavior is inspired by and similar to git's .git-folder seeking -logic when running git commands in a working dir.)</p> -<p>If no package root is found, then the current folder is used.</p> -<p>When you run <code>npm install foo@1.2.3</code>, then the package is loaded into -the cache, and then unpacked into <code>./node_modules/foo</code>. Then, any of -foo's dependencies are similarly unpacked into -<code>./node_modules/foo/node_modules/...</code>.</p> -<p>Any bin files are symlinked to <code>./node_modules/.bin/</code>, so that they may -be found by npm scripts when necessary.</p> -<h3 id="global-installation">Global Installation</h3> -<p>If the <code>global</code> configuration is set to true, then npm will -install packages "globally".</p> -<p>For global installation, packages are installed roughly the same way, -but using the folders described above.</p> -<h3 id="cycles-conflicts-and-folder-parsimony">Cycles, Conflicts, and Folder Parsimony</h3> -<p>Cycles are handled using the property of node's module system that it -walks up the directories looking for <code>node_modules</code> folders. So, at every -stage, if a package is already installed in an ancestor <code>node_modules</code> -folder, then it is not installed at the current location.</p> -<p>Consider the case above, where <code>foo -> bar -> baz</code>. Imagine if, in -addition to that, baz depended on bar, so you'd have: -<code>foo -> bar -> baz -> bar -> baz ...</code>. However, since the folder -structure is: <code>foo/node_modules/bar/node_modules/baz</code>, there's no need to -put another copy of bar into <code>.../baz/node_modules</code>, since when it calls -require("bar"), it will get the copy that is installed in -<code>foo/node_modules/bar</code>.</p> -<p>This shortcut is only used if the exact same -version would be installed in multiple nested <code>node_modules</code> folders. It -is still possible to have <code>a/node_modules/b/node_modules/a</code> if the two -"a" packages are different versions. However, without repeating the -exact same package multiple times, an infinite regress will always be -prevented.</p> -<p>Another optimization can be made by installing dependencies at the -highest level possible, below the localized "target" folder.</p> -<h4 id="example">Example</h4> -<p>Consider this dependency graph:</p> -<pre><code>foo -+-- blerg@1.2.5 -+-- bar@1.2.3 -| +-- blerg@1.x (latest=1.3.7) -| +-- baz@2.x -| | `-- quux@3.x -| | `-- bar@1.2.3 (cycle) -| `-- asdf@* -`-- baz@1.2.3 - `-- quux@3.x - `-- bar</code></pre><p>In this case, we might expect a folder structure like this:</p> -<pre><code>foo -+-- node_modules - +-- blerg (1.2.5) <---[A] - +-- bar (1.2.3) <---[B] - | `-- node_modules - | +-- baz (2.0.2) <---[C] - | | `-- node_modules - | | `-- quux (3.2.0) - | `-- asdf (2.3.4) - `-- baz (1.2.3) <---[D] - `-- node_modules - `-- quux (3.2.0) <---[E]</code></pre><p>Since foo depends directly on <code>bar@1.2.3</code> and <code>baz@1.2.3</code>, those are -installed in foo's <code>node_modules</code> folder.</p> -<p>Even though the latest copy of blerg is 1.3.7, foo has a specific -dependency on version 1.2.5. So, that gets installed at [A]. Since the -parent installation of blerg satisfies bar's dependency on <code>blerg@1.x</code>, -it does not install another copy under [B].</p> -<p>Bar [B] also has dependencies on baz and asdf, so those are installed in -bar's <code>node_modules</code> folder. Because it depends on <code>baz@2.x</code>, it cannot -re-use the <code>baz@1.2.3</code> installed in the parent <code>node_modules</code> folder [D], -and must install its own copy [C].</p> -<p>Underneath bar, the <code>baz -> quux -> bar</code> dependency creates a cycle. -However, because bar is already in quux's ancestry [B], it does not -unpack another copy of bar into that folder.</p> -<p>Underneath <code>foo -> baz</code> [D], quux's [E] folder tree is empty, because its -dependency on bar is satisfied by the parent folder copy installed at [B].</p> -<p>For a graphical breakdown of what is installed where, use <code>npm ls</code>.</p> -<h3 id="publishing">Publishing</h3> -<p>Upon publishing, npm will look in the <code>node_modules</code> folder. If any of -the items there are not in the <code>bundledDependencies</code> array, then they will -not be included in the package tarball.</p> -<p>This allows a package maintainer to install all of their dependencies -(and dev dependencies) locally, but only re-publish those items that -cannot be found elsewhere.
