Can not find module TypeScript <p>I am converting my nodejs project into typescript nodejs. I have changed the extensions of .js files to .ts, however now I am getting <strong>require()</strong> errors. To overcome this problem, I tried </p> <pre><code>import express from "express" </code></pre> <p>However this gives me <strong>"Can not find module error"</strong>. I have researched it and narrowed it down to the issue where I guess TypeScript needs <strong>express.d.ts</strong> file for detecting the Express module. However I couldn't find the <strong>express.d.ts</strong> file anywhere in my project. Which ultimately means I am missing something.</p> <p>Can somebody point me in the right direction or perhaps help me resolve this problem?</p>
