Call a nodejs script within another one : <p>I have a two files written in javascript (node.js): server.js and extra.js</p>

<p>In server.js. I need to call extra.js using this</p>

<p>node extra 123456</p>

<p>123456 is <code>process.argv[2]</code> of extra.js in this case</p>

<p>I would like to know which module should I use in order to make this call</p>
