Stable</div><p></p> <p>The <code>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('path'); </code></pre> <h2>Windows vs. POSIX<span><a class="mark" href="#path_windows_vs_posix" id="path_windows_vs_posix">#</a></span></h2> <p>The default operation of the <code>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>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="#path_path_win32"><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="#path_path_posix"><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>.
