  12 <h1><a href="../cli/npm-link.html">npm-link</a></h1> <p>Symlink a package folder</p>
  13 <h2 id="synopsis">SYNOPSIS</h2>
  14 <pre><code>npm link (in package folder)
  15 npm link &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.</p>
  21 <p>Next, in some other location, <code>npm link package-name</code> will create a
  22 symlink from the local <code>node_modules</code> folder to the global symlink.</p>
  23 <p>Note that <code>package-name</code> is taken from <code>package.json</code>,
  24 not from directory name.</p>
  25 <p>When creating tarballs for <code>npm publish</code>, the linked packages are
  26 &quot;snapshotted&quot; to their current state by resolving the symbolic links.</p>
  27 <p>This is
  28 handy for installing your own stuff, so that you can work on it and test it
  29 iteratively without having to continually rebuild.</p>
  30 <p>For example:</p>
  31 <pre><code>cd ~/projects/node-redis    # go into the package directory
  32 npm link                    # creates global link
  33 cd ~/projects/node-bloggy   # go into some other package directory.
  34 npm link redis              # link-install the package
  35 </code></pre><p>Now, any changes to ~/projects/node-redis will be reflected in
  36 ~/projects/node-bloggy/node_modules/redis/</p>
  37 <p>You may also shortcut the two steps in one.  For example, to do the
  38 above use-case in a shorter way:</p>
  39 <pre><code>cd ~/projects/node-bloggy  # go into the dir of your main project
  40 npm link ../node-redis     # link the dir of your dependency
  41 </code></pre><p>The second line is the equivalent of doing:</p>
  42 <pre><code>(cd ../node-redis; npm link)
  43 npm link redis
  44 </code></pre><p>That is, it first creates a global link, and then links the global
  45 installation target into your project&#39;s <code>node_modules</code> folder.</p>
