  20
  21 <p>Package linking is a two-step process.</p>
  22
  23 <p>First, <code>npm link</code> in a package folder will create a globally-installed
  24 symbolic link from <code>prefix/package-name</code> to the current folder.</p>
  25
  26 <p>Next, in some other location, <code>npm link package-name</code> will create a
  27 symlink from the local <code>node_modules</code> folder to the global symlink.</p>
  28
  29 <p>Note that <code>package-name</code> is taken from <code>package.json</code>,
  30 not from directory name.</p>
  31
  32 <p>When creating tarballs for <code>npm publish</code>, the linked packages are
  33 &quot;snapshotted&quot; to their current state by resolving the symbolic links.</p>
  34
  35 <p>This is
  36 handy for installing your own stuff, so that you can work on it and test it
  37 iteratively without having to continually rebuild.</p>
  38
  39 <p>For example:</p>
  40
  41 <pre><code>cd ~/projects/node-redis    # go into the package directory
  42 npm link                    # creates global link
  43 cd ~/projects/node-bloggy   # go into some other package directory.
  44 npm link redis              # link-install the package</code></pre>
  45
  46 <p>Now, any changes to ~/projects/node-redis will be reflected in
  47 ~/projects/node-bloggy/node_modules/redis/</p>
  48
  49 <p>You may also shortcut the two steps in one.  For example, to do the
  50 above use-case in a shorter way:</p>
  51
  52 <pre><code>cd ~/projects/node-bloggy  # go into the dir of your main project
  53 npm link ../node-redis     # link the dir of your dependency</code></pre>
  54
  55 <p>The second line is the equivalent of doing:</p>
  56
  57 <pre><code>(cd ../node-redis; npm link)
  58 npm link redis</code></pre>
  59
  60 <p>That is, it first creates a global link, and then links the global
  61 installation target into your project&#39;s <code>node_modules</code> folder.</p>
