In a plain web page:

<script type="module">
  import { interceptConsole } from './dist/ulak.js';
  interceptConsole();
</script>

In a project where a bundler is present:

add ulak to package.json

{
  "dependencies": {
    "ulak": "x.y.z"
  }
}

then:

import { interceptConsole } from 'ulak';

interceptConsole();

In both cases you need the following HTML tag in your page:

<bug-report-button text="Hata Bildir"></bug-report-button>
