Could not find HammerJS in angular 6

March 22, 2023 by Tarik

There are 2 ways to solve this problem:

Either include the (main) import in your main module’s file or polyfills.ts:
```
import 'hammerjs';
```

Or include the script from a CDN into your index.html file:

<head>
  <!-- ... -->
  <script src="https://cdnjs.cloudflare.com/ajax/libs/hammer.js/2.0.8/hammer.min.js"></script>
  <!-- ... -->
</head>
