<h2 id="DESCRIPTION">DESCRIPTION</h2>
|
|
|
|
<p>Package linking is a two-step process.</p>
|
|
|
|
<p>First, <code>npm link</code> in a package folder will create a globally-installed
|
|
symbolic link from <code>prefix/package-name</code> to the current folder.</p>
|
|
|
|
<p>Next, in some other location, <code>npm link package-name</code> will create a
|
|
symlink from the local <code>node_modules</code> folder to the global symlink.</p>
|
|
|
|
<p>Note that <code>package-name</code> is taken from <code>package.json</code>,
|
|
not from directory name.</p>
|
|
|
|
<p>When creating tarballs for <code>npm publish</code>, the linked packages are
|
|
"snapshotted" to their current state by resolving the symbolic links.</p>
|
|
|
|
<p>This is
|
|
handy for installing your own stuff, so that you can work on it and test it
|
|
iteratively without having to continually rebuild.</p>
|
|
|
|
<p>For example:</p>
|
|
|
|
<pre><code>cd ~/projects/node-redis # go into the package directory
|
|
npm link # creates global link
|
|
cd ~/projects/node-bloggy # go into some other package directory.
|
|
npm link redis # link-install the package</code></pre>
|
|
|
|
<p>Now, any changes to ~/projects/node-redis will be reflected in
|
|
~/projects/node-bloggy/node_modules/redis/</p>
|
|
|
|
<p>You may also shortcut the two steps in one. For example, to do the
|
|
above use-case in a shorter way:</p>
|
|
|
|
<pre><code>cd ~/projects/node-bloggy # go into the dir of your main project
|
|
npm link ../node-redis # link the dir of your dependency</code></pre>
|
|
|
|
<p>The second line is the equivalent of doing:</p>
|
|
|
|
<pre><code>(cd ../node-redis; npm link)
|
|
npm link redis</code></pre>
|
|
|
|
<p>That is, it first creates a global link, and then links the global
|
|
installation target into your project's <code>node_modules</code> folder.</p>
