Eleventy: Any {{ excerpt }} example ?

[smaimon]

Hi,
I try to parse {{ excerpts }} from content based on the example available on 11ty.dev with no success.
Does anyone have a website repository who use the excerpt in order to help me understand my mistake ?

Thank you for this approach.

Sébastien

filter code /src/excerpt

const seperator = {start: '', end: ''};

module.exports = function(article) {

if (startPosition !== -1 && endPosition !== -1) {
    excerpt = articleContent.substring(startPosition + seperator.start.length, endPosition);
} else if (!article.data.excerpt) {
    let startPosition = articleContent.toLowerCase().indexOf('<p>');
    let endPosition = articleContent.toLowerCase().indexOf('</p>');

    excerpt = articleContent.substring(startPosition + 3, endPosition);
}
return excerpt

}

     }
     return excerpt
 }

If that works for you, could you close the issue, @smaimon?
