 "desc": "The semantics of the Node.js <code>require()</code> function were designed to be general\nenough to support reasonable directory structures. Package manager programs\nsuch as <code>dpkg</code>, <code>rpm</code>, and <code>npm</code> will hopefully find it possible to build\nnative packages from Node.js modules without modification.\nBelow we give a suggested directory structure that could work:\nLet's say that we wanted to have the folder at\n<code>/usr/lib/node/&#x3C;some-package>/&#x3C;some-version></code> hold the contents of a\nspecific version of a package.\nPackages can depend on one another. In order to install package <code>foo</code>, it\nmay be necessary to install a specific version of package <code>bar</code>. The <code>bar</code>\npackage may itself have dependencies, and in some cases, these may even collide\nor form cyclic dependencies.\nBecause Node.js looks up the <code>realpath</code> of any modules it loads (that is, it\nresolves symlinks) and then <a href=\"#modules_loading_from_node_modules_folders\">looks for their dependencies in <code>node_modules</code> folders</a>,\nthis situation can be resolved with the following architecture:\n<ul>\n<li><code>/usr/lib/node/foo/1.2.3/</code>: Contents of the <code>foo</code> package, version 1.2.3.</li>\n<li><code>/usr/lib/node/bar/4.3.2/</code>: Contents of the <code>bar</code> package that <code>foo</code> depends\non.</li>\n<li><code>/usr/lib/node/foo/1.2.3/node_modules/bar</code>: Symbolic link to\n<code>/usr/lib/node/bar/4.3.2/</code>.</li>\n<li><code>/usr/lib/node/bar/4.3.2/node_modules/*</code>: Symbolic links to the packages that\n<code>bar</code> depends on.</li>\n</ul>\nThus, even if a cycle is encountered, or if there are dependency\nconflicts, every module will be able to get a version of its dependency\nthat it can use.\nWhen the code in the <code>foo</code> package does <code>require('bar')</code>, it will get the\nversion that is symlinked into <code>/usr/lib/node/foo/1.2.3/node_modules/bar</code>.\nThen, when the code in the <code>bar</code> package calls <code>require('quux')</code>, it'll get\nthe version that is symlinked into\n<code>/usr/lib/node/bar/4.3.2/node_modules/quux</code>.\nFurthermore, to make the module lookup process even more optimal, rather\nthan putting packages directly in <code>/usr/lib/node</code>, we could put them in\n<code>/usr/lib/node_modules/&#x3C;name>/&#x3C;version></code>. Then Node.js will not bother\nlooking for missing dependencies in <code>/usr/node_modules</code> or <code>/node_modules</code>.\nIn order to make modules available to the Node.js REPL, it might be useful to\nalso add the <code>/usr/lib/node_modules</code> folder to the <code>$NODE_PATH</code> environment\nvariable. Since the module lookups using <code>node_modules</code> folders are all\nrelative, and based on the real path of the files making the calls to\n<code>require()</code>, the packages themselves can be anywhere."
