  13 <h2 id="synopsis">SYNOPSIS</h2>
  14 <pre><code>npm link (in package folder)
  15 npm link [@&lt;scope&gt;/]&lt;pkgname&gt;
  16 npm ln (with any of the previous argument usage)
  17 </code></pre><h2 id="description">DESCRIPTION</h2>
  18 <p>Package linking is a two-step process.</p>
  19 <p>First, <code>npm link</code> in a package folder will create a globally-installed
  20 symbolic link from <code>prefix/package-name</code> to the current folder (see
  21 <code><a href="../misc/npm-config.html"><a href="../misc/npm-config.html">npm-config(7)</a></a></code> for the value of <code>prefix</code>).</p>
  22 <p>Next, in some other location, <code>npm link package-name</code> will create a
  23 symlink from the local <code>node_modules</code> folder to the global symlink.</p>
  24 <p>Note that <code>package-name</code> is taken from <code>package.json</code>,
  25 not from directory name.</p>
  26 <p>The package name can be optionally prefixed with a scope. See <code><a href="../misc/npm-scope.html"><a href="../misc/npm-scope.html">npm-scope(7)</a></a></code>.
  27 The scope must be preceded by an @-symbol and followed by a slash.</p>
  28 <p>When creating tarballs for <code>npm publish</code>, the linked packages are
  29 &quot;snapshotted&quot; to their current state by resolving the symbolic links.</p>
  30 <p>This is handy for installing your own stuff, so that you can work on it and
  31 test it iteratively without having to continually rebuild.</p>
  32 <p>For example:</p>
  33 <pre><code>cd ~/projects/node-redis    # go into the package directory
  34 npm link                    # creates global link
  35 cd ~/projects/node-bloggy   # go into some other package directory.
  36 npm link redis              # link-install the package
  37 </code></pre><p>Now, any changes to ~/projects/node-redis will be reflected in
  38 ~/projects/node-bloggy/node_modules/node-redis/</p>
  39 <p>You may also shortcut the two steps in one.  For example, to do the
  40 above use-case in a shorter way:</p>
  41 <pre><code>cd ~/projects/node-bloggy  # go into the dir of your main project
  42 npm link ../node-redis     # link the dir of your dependency
  43 </code></pre><p>The second line is the equivalent of doing:</p>
  44 <pre><code>(cd ../node-redis; npm link)
  45 npm link node-redis
  46 </code></pre><p>That is, it first creates a global link, and then links the global
  47 installation target into your project&#39;s <code>node_modules</code> folder.</p>
  48 <p>If your linked package is scoped (see <code><a href="../misc/npm-scope.html"><a href="../misc/npm-scope.html">npm-scope(7)</a></a></code>) your link command must
  49 include that scope, e.g.</p>
  50 <pre><code>npm link @myorg/privatepackage
  51 </code></pre><h2 id="see-also">SEE ALSO</h2>
