You can use 

<pre><code>fs.stat('/folder1/folder2', function(err, stats){ ... });
</code></pre>

<code>stats</code> is a <code>fs.Stats</code> type of object, you may check <code>stats.isDirectory()</code>. Depending on the examination of <code>err</code> and <code>stats</code> you can do something, <code>fs.mkdir( ... )</code> or throw an error.

As of Node v10, this is built into the <a href="https://nodejs.org/api/fs.html#fs_fs_mkdir_path_options_callback" rel="noreferrer">fs.mkdir</a> function, which we can use in combination with <a href="http://nodejs.org/api/path.html#path_path_dirname_p" rel="noreferrer">path.dirname</a>:
<pre><code>var fs = require('fs');
var getDirName = require('path').dirname;

function writeFile(path, contents, cb) {
 fs.mkdir(getDirName(path), { recursive: true}, function (err) {
 if (err) return cb(err);

 fs.writeFile(path, contents, cb);
 });
}
</code></pre>
For older versions, you can use <a href="https://npmjs.org/package/mkdirp" rel="noreferrer">mkdirp</a>:
<pre><code>var mkdirp = require('mkdirp');
var fs = require('fs');
var getDirName = require('path').dirname;

function writeFile(path, contents, cb) {
 mkdirp(getDirName(path), function (err) {
 if (err) return cb(err);
 
 fs.writeFile(path, contents, cb);
 });
}
</code></pre>
If the whole path already exists, <code>mkdirp</code> is a noop. Otherwise it creates all missing directories for you.
This module does what you want: <a href="https://npmjs.org/package/writefile" rel="noreferrer">https://npmjs.org/package/writefile</a> . Got it when googling for &quot;writefile mkdirp&quot;. This module returns a promise instead of taking a callback, so be sure to read some introduction to promises first. It might actually complicate things for you.
The function I gave works in any case.

Edit
NodeJS version <a href="https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V10.md#2018-10-10-version-10120-current-targos" rel="nofollow noreferrer"><code>10.12.0</code></a> has added a native support for both <code>mkdir</code> and <code>mkdirSync</code> to create the parent director recursively with <a href="https://nodejs.org/api/fs.html#fs_fs_mkdirsync_path_options" rel="nofollow noreferrer"><code>recursive: true</code></a> option as the following:
<pre><code>fs.mkdirSync(targetDir, { recursive: true });
</code></pre>
And if you prefer <a href="https://nodejs.org/api/fs.html#fs_fs_promises_api" rel="nofollow noreferrer"><code>fs Promises API</code></a>, you can write
<pre><code>fs.promises.mkdir(targetDir, { recursive: true });
</code></pre>
<h2>Original Answer</h2>
Create the parent directories recursively if they do not exist! (Zero dependencies)
<pre><code>const fs = require('fs');
const path = require('path');

function mkDirByPathSync(targetDir, { isRelativeToScript = false } = {}) {
 const sep = path.sep;
 const initDir = path.isAbsolute(targetDir) ? sep : '';
 const baseDir = isRelativeToScript ? __dirname : '.';

 return targetDir.split(sep).reduce((parentDir, childDir) =&gt; {
 const curDir = path.resolve(baseDir, parentDir, childDir);
 try {
 fs.mkdirSync(curDir);
 } catch (err) {
 if (err.code === 'EEXIST') { // curDir already exists!
 return curDir;
 }

 // To avoid `EISDIR` error on Mac and `EACCES`--&gt;`ENOENT` and `EPERM` on Windows.
 if (err.code === 'ENOENT') { // Throw the original parentDir error on curDir `ENOENT` failure.
 throw new Error(`EACCES: permission denied, mkdir '${parentDir}'`);
 }

 const caughtErr = ['EACCES', 'EPERM', 'EISDIR'].indexOf(err.code) &gt; -1;
 if (!caughtErr || caughtErr &amp;&amp; curDir === path.resolve(targetDir)) {
 throw err; // Throw if it's just the last created dir.
 }
 }

 return curDir;
 }, initDir);
}
</code></pre>
<h3>Usage</h3>
<pre><code>// Default, make directories relative to current working directory.
mkDirByPathSync('path/to/dir');

// Make directories relative to the current script.
mkDirByPathSync('path/to/dir', {isRelativeToScript: true});

// Make directories with an absolute path.
mkDirByPathSync('/path/to/dir');
</code></pre>
<h3>Demo</h3>
<a href="https://rextester.com/RYCC11960" rel="nofollow noreferrer">Try It!</a>
<h3>Explanations</h3>
<ul>
<li>[UPDATE] This solution handles platform-specific errors like <code>EISDIR</code> for Mac and <code>EPERM</code> and <code>EACCES</code> for Windows.</li>
<li>This solution handles both relative and absolute paths.</li>
<li>In the case of relative paths, target directories will be created (resolved) in the current working directory. To Resolve them relative to the current script dir, pass <code>{isRelativeToScript: true}</code>.</li>
<li>Using <a href="https://nodejs.org/api/path.html#path_path_sep" rel="nofollow noreferrer"><code>path.sep</code></a> and <a href="https://nodejs.org/api/path.html#path_path_resolve_paths" rel="nofollow noreferrer"><code>path.resolve()</code></a>, not just <code>/</code> concatenation, to avoid cross-platform issues.</li>
<li>Using <a href="https://nodejs.org/api/fs.html#fs_fs_mkdirsync_path_mode" rel="nofollow noreferrer"><code>fs.mkdirSync</code></a> and handling the error with <code>try/catch</code> if thrown to handle race conditions: another process may add the file between the calls to <a href="https://nodejs.org/api/fs.html#fs_fs_existssync_path" rel="nofollow noreferrer"><code>fs.existsSync()</code></a> and <a href="https://nodejs.org/api/fs.html#fs_fs_mkdirsync_path_mode" rel="nofollow noreferrer"><code>fs.mkdirSync()</code></a> and causes an exception.
<ul>
<li>The other way to achieve that could be checking if a file exists then creating it, I.e, <code>if (!fs.existsSync(curDir) fs.mkdirSync(curDir);</code>. But this is an anti-pattern that leaves the code vulnerable to race conditions.</li>
</ul>
</li>
<li>Requires Node v6 and newer to support destructuring. (If you have problems implementing this solution with old Node versions, just leave me a comment)</li>
</ul>

I find that the easiest way to do this is to use the <a href="https://github.com/jprichardson/node-fs-extra/blob/master/docs/outputFile.md" rel="noreferrer">outputFile</a>() method from the <a href="https://www.npmjs.com/package/fs-extra" rel="noreferrer">fs-extra</a> module.

<blockquote>
 Almost the same as writeFile (i.e. it overwrites), except that if the parent directory does not exist, it's created. options are what you'd pass to fs.writeFile().
</blockquote>

Example:

<pre><code>var fs = require('fs-extra');
var file = '/tmp/this/path/does/not/exist/file.txt'

fs.outputFile(file, 'hello!', function (err) {
 console.log(err); // =&gt; null

 fs.readFile(file, 'utf8', function (err, data) {
 console.log(data); // =&gt; hello!
 });
});
</code></pre>

It also has promise support out of the box these days!.

With node-fs-extra you can do it easily.

Install it

<pre><code>npm install --save fs-extra
</code></pre>

Then use the outputFile method instead of writeFileSync 

<pre><code>const fs = require('fs-extra');

fs.outputFile('tmp/test.txt', 'Hey there!', err =&gt; {
 if(err) {
 console.log(err);
 } else {
 console.log('The file was saved!');
 }
})
</code></pre>

This code in windows create file in 2 folder above the current folder.
<blockquote>
but I Can't create file in C:\ Directly
</blockquote>

I need to write file to the following path:

<pre class="lang-js prettyprint-override"><code>fs.writeFile('/folder1/folder2/file.txt', 'content', function () {…});
</code></pre>

But <code>'/folder1/folder2'</code> path may not exists. So I get the following error:

<blockquote>
 message=ENOENT, open /folder1/folder2/file.txt
</blockquote>

How can I write content to that path?

How to write file if parent folder doesn't exist?

Windows

我需要将文件写入以下路径：fs.writeFile('/folder1/folder2/file.txt', 'content', function () {…});但'/folder1/folder2'路径可能不存在。因此，我得到以下错误： message=ENOENT，打开/folder1/folder2/file...
