Alternative to fs.readFileSync()
<p>I'm importing a css file into my npm module with <a href="https://github.com/substack/insert-css" rel="nofollow">Insert-css</a> but i get an error.</p>

<pre><code>var fs = require('fs');
var inserCss = require('insert-css');
var css = fs.readFileSync(__dirname + '../css/file.css');
insertCss(css);
</code></pre>

<p>and the error I'm getting is </p>

<p>"Uncaught TypeError: fs.readFileSync is not a function"</p>

<p>Is there any alternative for fs.readFileSync? maybe npm module "Path"? </p>
