How to add approx read time on posts in Jigsaw?

My current blog is developed using Jigsaw and their awesome template.

Jigsaw is a framework for rapidly building static sites using the same modern tooling that powers your web applications.

I absolutely love the design and made little to no changes on it. One thing I very much needed is to show read time on each article. This is how I accomplished it.

• Add a new helper in config.php.

'getReadTime' => function ($page, $wpm = 150) {
        $content = strip_tags($page->getContent());
        $word_count = str_word_count($content);
        return ceil($word_count / $wpm);
    }

• Use the helper in post-preview-inline.blade.php. In blog template this file is used to give an inline preview of posts.

 <a
    href="{{ $post->getUrl() }}"
    title="Read more - {{ $post->title }}"
    class="uppercase font-semibold tracking-wide mb-2"
    >
    {{ $post->getReadTime() }}  Minutes Read 
</a>
