310<p>The <code>node:path</code> module provides utilities for working with file and directory
311paths. It can be accessed using:</p>
312<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>
313<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>
314<p>The default operation of the <code>node:path</code> module varies based on the operating
315system on which a Node.js application is running. Specifically, when running on
316a Windows operating system, the <code>node:path</code> module will assume that
317Windows-style paths are being used.</p>
318<p>So using <code>path.basename()</code> might yield different results on POSIX and Windows:</p>
319<p>On POSIX:</p>
320<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
321<span class="hljs-comment">// Returns: 'C:\\temp\\myfile.html'</span></code> <button class="copy-button">copy</button></pre>
322<p>On Windows:</p>
323<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
324<span class="hljs-comment">// Returns: 'myfile.html'</span></code> <button class="copy-button">copy</button></pre>
325<p>To achieve consistent results when working with Windows file paths on any
326operating system, use <a href="#pathwin32"><code>path.win32</code></a>:</p>
327<p>On POSIX and Windows:</p>
328<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>);
329<span class="hljs-comment">// Returns: 'myfile.html'</span></code> <button class="copy-button">copy</button></pre>
330<p>To achieve consistent results when working with POSIX file paths on any
331operating system, use <a href="#pathposix"><code>path.posix</code></a>:</p>
332<p>On POSIX and Windows:</p>
333<pre><code class="language-js">path.<span class="hljs-property">posix</span>.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'/tmp/myfile.html'</span>);
334<span class="hljs-comment">// Returns: 'myfile.html'</span></code> <button class="copy-button">copy</button></pre>
335<p>On Windows Node.js follows the concept of per-drive working directory.
336This behavior can be observed when using a drive path without a backslash. For
337example, <code>path.resolve('C:\\')</code> can potentially return a different result than
338<code>path.resolve('C:')</code>. For more information, see
339<a href="https://docs.microsoft.com/en-us/windows/desktop/FileIO/naming-a-file#fully-qualified-vs-relative-paths">this MSDN page</a>.</p>

357<p>The <code>path.basename()</code> method returns the last portion of a <code>path</code>, similar to

365<p>Although Windows usually treats file names, including file extensions, in a
366case-insensitive manner, this function does not. For example, <code>C:\\foo.html</code> and
367<code>C:\\foo.HTML</code> refer to the same file, but <code>basename</code> treats the extension as a
368case-sensitive string:</p>
369<pre><code class="language-js">path.<span class="hljs-property">win32</span>.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\foo.html'</span>, <span class="hljs-string">'.html'</span>);

570<p>The <code>path.normalize()</code> method normalizes the given <code>path</code>, resolving <code>'..'</code> and
571<code>'.'</code> segments.</p>
572<p>When multiple, sequential path segment separation characters are found (e.g.
573<code>/</code> on POSIX and either <code>\</code> or <code>/</code> on Windows), they are replaced by a single
574instance of the platform-specific path segment separator (<code>/</code> on POSIX and
575<code>\</code> on Windows). Trailing separators are preserved.</p>
576<p>If the <code>path</code> is a zero-length string, <code>'.'</code> is returned, representing the
577current working directory.</p>
578<p>For example, on POSIX:</p>
579<pre><code class="language-js">path.<span class="hljs-title function_">normalize</span>(<span class="hljs-string">'/foo/bar//baz/asdf/quux/..'</span>);

583<span class="hljs-comment">// Returns: 'C:\\temp\\foo\\'</span></code> <button class="copy-button">copy</button></pre>

694<p>The <code>path.resolve()</code> method resolves a sequence of paths or path segments into
695an absolute path.</p>
696<p>The given sequence of paths is processed from right to left, with each
697subsequent <code>path</code> prepended until an absolute path is constructed.
698For instance, given the sequence of path segments: <code>/foo</code>, <code>/bar</code>, <code>baz</code>,
699calling <code>path.resolve('/foo', '/bar', 'baz')</code> would return <code>/bar/baz</code>
700because <code>'baz'</code> is not an absolute path but <code>'/bar' + '/' + 'baz'</code> is.</p>
701<p>If, after processing all given <code>path</code> segments, an absolute path has not yet
702been generated, the current working directory is used.</p>
703<p>The resulting path is normalized and trailing slashes are removed unless the
704path is resolved to the root directory.</p>
705<p>Zero-length <code>path</code> segments are ignored.</p>
706<p>If no <code>path</code> segments are passed, <code>path.resolve()</code> will return the absolute path
707of the current working directory.</p>
