<p><strong>Source Code:</strong> <a href="https://github.com/nodejs/node/blob/v20.18.0/lib/path.js">lib/path.js</a></p>
<p>The <code>node:path</code> module provides utilities for working with file and directory
paths. It can be accessed using:</p>
<pre><code class="language-js"><span class="hljs-keyword">const</span> path = <span class="hljs-built_in">require</span>(<span class="hljs-string">'node:path'</span>);</code> <button class="copy-button">copy</button></pre>
<section><h3>Windows vs. POSIX<span><a class="mark" href="#windows-vs-posix" id="windows-vs-posix">#</a></span><a aria-hidden="true" class="legacy" id="path_windows_vs_posix"></a></h3>
<p>The default operation of the <code>node:path</code> module varies based on the operating
system on which a Node.js application is running. Specifically, when running on
a Windows operating system, the <code>node:path</code> module will assume that
Windows-style paths are being used.</p>
<p>So using <code>path.basename()</code> might yield different results on POSIX and Windows:</p>
<p>On POSIX:</p>
<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
<span class="hljs-comment">// Returns: 'C:\\temp\\myfile.html'</span></code> <button class="copy-button">copy</button></pre>
<p>On Windows:</p>
<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
<span class="hljs-comment">// Returns: 'myfile.html'</span></code> <button class="copy-button">copy</button></pre>
<p>To achieve consistent results when working with Windows file paths on any
operating system, use <a href="#pathwin32"><code>path.win32</code></a>:</p>
<p>On POSIX and Windows:</p>
<pre><code class="language-js">path.<span class="hljs-property">win32</span>.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
<span class="hljs-comment">// Returns: 'myfile.html'</span></code> <button class="copy-button">copy</button></pre>
<p>To achieve consistent results when working with POSIX file paths on any

<p>On Windows Node.js follows the concept of per-drive working directory.
This behavior can be observed when using a drive path without a backslash. For
example, <code>path.resolve('C:\\')</code> can potentially return a different result than
<code>path.resolve('C:')</code>. For more information, see

</ul>
<p>The <code>path.normalize()</code> method normalizes the given <code>path</code>, resolving <code>'..'</code> and
<code>'.'</code> segments.</p>
<p>When multiple, sequential path segment separation characters are found (e.g.
<code>/</code> on POSIX and either <code>\</code> or <code>/</code> on Windows), they are replaced by a single
instance of the platform-specific path segment separator (<code>/</code> on POSIX and
<code>\</code> on Windows). Trailing separators are preserved.</p>
<p>If the <code>path</code> is a zero-length string, <code>'.'</code> is returned, representing the
current working directory.</p>
<p>On POSIX, the types of normalization applied by this function do not strictly
adhere to the POSIX specification. For example, this function will replace two
leading forward slashes with a single slash as if it was a regular absolute
path, whereas a few POSIX systems assign special meaning to paths beginning with
exactly two forward slashes. Similarly, other substitutions performed by this
function, such as removing <code>..</code> segments, may change how the underlying system
resolves the path.</p>
<p>For example, on POSIX:</p>
<pre><code class="language-js">path.<span class="hljs-title function_">normalize</span>(<span class="hljs-string">'/foo/bar//baz/asdf/quux/..'</span>);
<span class="hljs-comment">// Returns: '/foo/bar/baz/asdf'</span></code> <button class="copy-button">copy</button></pre>

<span class="hljs-comment">// Returns: 'C:\\temp\\foo\\'</span></code> <button class="copy-button">copy</button></pre>
<p>Since Windows recognizes multiple path separators, both separators will be
replaced by instances of the Windows preferred separator (<code>\</code>):</p>
<pre><code class="language-js">path.<span class="hljs-property">win32</span>.<span class="hljs-title function_">normalize</span>(<span class="hljs-string">'C:////temp\\\\/\\/\\/foo/bar'</span>);

<p>The <code>path.relative()</code> method returns the relative path from <code>from</code> to <code>to</code> based
on the current working directory. If <code>from</code> and <code>to</code> each resolve to the same
path (after calling <code>path.resolve()</code> on each), a zero-length string is returned.</p>
<p>If a zero-length string is passed as <code>from</code> or <code>to</code>, the current working
directory will be used instead of the zero-length strings.</p>
<p>For example, on POSIX:</p>
<pre><code class="language-js">path.<span class="hljs-title function_">relative</span>(<span class="hljs-string">'/data/orandea/test/aaa'</span>, <span class="hljs-string">'/data/orandea/impl/bbb'</span>);

</ul>
<p>The <code>path.resolve()</code> method resolves a sequence of paths or path segments into
an absolute path.</p>
<p>The given sequence of paths is processed from right to left, with each
subsequent <code>path</code> prepended until an absolute path is constructed.
For instance, given the sequence of path segments: <code>/foo</code>, <code>/bar</code>, <code>baz</code>,
calling <code>path.resolve('/foo', '/bar', 'baz')</code> would return <code>/bar/baz</code>
because <code>'baz'</code> is not an absolute path but <code>'/bar' + '/' + 'baz'</code> is.</p>
<p>If, after processing all given <code>path</code> segments, an absolute path has not yet
been generated, the current working directory is used.</p>
<p>The resulting path is normalized and trailing slashes are removed unless the
path is resolved to the root directory.</p>
<p>Zero-length <code>path</code> segments are ignored.</p>
<p>If no <code>path</code> segments are passed, <code>path.resolve()</code> will return the absolute path
of the current working directory.</p>

slashes (<code>\</code>).</p>
