173<p>The <code>path</code> module provides utilities for working with file and directory paths.
174It can be accessed using:</p>
175<pre><code class="language-js"><span class="hljs-keyword">const</span> path = <span class="hljs-built_in">require</span>(<span class="hljs-string">'path'</span>);</code></pre>
176<section><h3>Windows vs. POSIX<span><a class="mark" href="#path_windows_vs_posix" id="path_windows_vs_posix">#</a></span></h3>
177<p>The default operation of the <code>path</code> module varies based on the operating system
178on which a Node.js application is running. Specifically, when running on a
179Windows operating system, the <code>path</code> module will assume that Windows-style
180paths are being used.</p>
181<p>So using <code>path.basename()</code> might yield different results on POSIX and Windows:</p>
182<p>On POSIX:</p>
183<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
184<span class="hljs-comment">// Returns: 'C:\\temp\\myfile.html'</span></code></pre>
185<p>On Windows:</p>
186<pre><code class="language-js">path.<span class="hljs-title function_">basename</span>(<span class="hljs-string">'C:\\temp\\myfile.html'</span>);
187<span class="hljs-comment">// Returns: 'myfile.html'</span></code></pre>
188<p>To achieve consistent results when working with Windows file paths on any
189operating system, use <a href="#path_path_win32"><code>path.win32</code></a>:</p>
190<p>On POSIX and Windows:</p>
191<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>);
192<span class="hljs-comment">// Returns: 'myfile.html'</span></code></pre>
193<p>To achieve consistent results when working with POSIX file paths on any
194operating system, use <a href="#path_path_posix"><code>path.posix</code></a>:</p>
195<p>On POSIX and Windows:</p>
196<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>);
197<span class="hljs-comment">// Returns: 'myfile.html'</span></code></pre>
198<p>On Windows Node.js follows the concept of per-drive working directory.
199This behavior can be observed when using a drive path without a backslash. For
200example, <code>path.resolve('C:\\')</code> can potentially return a different result than
201<code>path.resolve('C:')</code>. For more information, see
202<a href="https://docs.microsoft.com/en-us/windows/desktop/FileIO/naming-a-file#fully-qualified-vs-relative-paths">this MSDN page</a>.</p>

220<p>The <code>path.basename()</code> method returns the last portion of a <code>path</code>, similar to
221the Unix <code>basename</code> command. Trailing directory separators are ignored, see

229case-insensitive manner, this function does not. For example, <code>C:\\foo.html</code> and
230<code>C:\\foo.HTML</code> refer to the same file, but <code>basename</code> treats the extension as a
231case-sensitive string:</p>
232<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>);

550<p>The given sequence of paths is processed from right to left, with each
551subsequent <code>path</code> prepended until an absolute path is constructed.
552For instance, given the sequence of path segments: <code>/foo</code>, <code>/bar</code>, <code>baz</code>,
553calling <code>path.resolve('/foo', '/bar', 'baz')</code> would return <code>/bar/baz</code>
554because <code>'baz'</code> is not an absolute path but <code>'/bar' + '/' + 'baz'</code> is.</p>
555<p>If, after processing all given <code>path</code> segments, an absolute path has not yet
556been generated, the current working directory is used.</p>
557<p>The resulting path is normalized and trailing slashes are removed unless the
558path is resolved to the root directory.</p>
559<p>Zero-length <code>path</code> segments are ignored.</p>
560<p>If no <code>path</code> segments are passed, <code>path.resolve()</code> will return the absolute path
561of the current working directory.</p>

580<ul>
581<li><code>\</code> on Windows</li>
582<li><code>/</code> on POSIX</li>
583</ul>
584<p>For example, on POSIX:</p>

586<span class="hljs-comment">// Returns: ['foo', 'bar', 'baz']</span></code></pre>
587<p>On Windows:</p>
588<pre><code class="language-js"><span class="hljs-string">'foo\\bar\\baz'</span>.<span class="hljs-title function_">split</span>(path.<span class="hljs-property">sep</span>);
589<span class="hljs-comment">// Returns: ['foo', 'bar', 'baz']</span></code></pre>
590<p>On Windows, both the forward slash (<code>/</code>) and backward slash (<code>\</code>) are accepted
591as path segment separators; however, the <code>path</code> methods only add backward
592slashes (<code>\</code>).</p>
