<h2>Path<span><a class="mark" href="#path" id="path">#</a></span><a aria-hidden="true" class="legacy" id="path_path"></a></h2> <!--introduced_in=v0.10.0--> <blockquote> <p>Stability: 2 - Stable</p> </blockquote> <!-- source_link=lib/path.js --> <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">const path = require('node:path'); </code></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.basename('C:\\temp\\myfile.html'); // Returns: 'C:\\temp\\myfile.html' </code></pre> <p>On Windows:</p> <pre><code class="language-js">path.basename('C:\\temp\\myfile.html'); // Returns: 'myfile.html' </code></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.win32.basename('C:\\temp\\myfile.html'); // Returns: 'myfile.html' </code></pre> <p>To achieve consistent results when working with POSIX file paths on any operating system, use <a href="#pathposix"><code>path.posix</code></a>:</p> <p>On POSIX and Windows:</p> <pre><code class="language-js">path.posix.basename('/tmp/myfile.html'); // Returns: 'myfile.html' </code></pre> <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 <a href="https://docs.microsoft.com/en-us/windows/desktop/FileIO/naming-a-file#fully-qualified-vs-relative-paths">this MSDN page</a>.</p> </section><section><h3><code>path.basename(path[, suffix])</code><span><a class="mark" href="#pathbasenamepath-suffix" id="pathbasenamepath-suffix">#</a></span><a aria-hidden="true" class="legacy" id="path_path_basename_path_suffix"></a></h3> <div class="api_metadata"> <details class="changelog"><summary>History</summary> <table> <tr><th>Version</th><th>Changes</th></tr> <tr><td>v6.0.0</td> <td><p>Passing a non-string as the <code>path</code> argument will throw now.</p> </td></tr> <tr><td>v0.1.25</td> <td><p><span>Added in: v0.1.25</span></p> </td></tr> </table> </details> </div><ul> <li><code>path</code> <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#String_type" class="type"><string></a></li> <li><code>suffix</code> <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#String_type" class="type"><string></a> An optional suffix to remove</li> <li>Returns: <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#String_type" class="type"><string></a></li> </ul> <p>The <code>path.basename()</code> method returns the last portion of a <code>path</code>, similar to the Unix <code>basename</code> command.
