Changing preview of the notes with a customized description in frontmatter backlink’s notes

[yazae]

Hi, I’m in the process of writing my personnal blog and adapting your theme. I know it’s a long shot since it’s an older project of you, but I have a question for you :

What I’m trying to do : adapting my notefeed to your backlinks :

In my notefeed in Notes, I have my current notes, displayed with their titles, and their personnal description, which is a field in the frontmatter.
I was finding the chore of sanitizing an excerpt too much of a hassle, so I’v gone this way.

The tipical frontmatter is something like that :

---
title: "Liste d’articles à lire en 2023"
aliases: 
- À lire
notetype: feed
date: 2023-07-09
edit: 2023-07-09
tags:
  - militantisme
  - liste
description: "Une liste d'article intéressants que j'ai lu / que je dois lire en ce moment."
---

So, notefeed is going fine. But, when I’m adapting it to your backlinks, I’m having a problem I’m not sure I understand correctly.

Backlinks

So, while adapting the css, it works just fine

But, of course, I’m finding some note who aren’t sanityzed in the exerpt, and it makes a mess.

So I tried to adapt your notes.11tydata.js, and we’re here at the heart of the problem : I don’t understand how it truly works to adapt it correctly.

here is the original for reference :

module.exports = {
    layout: "note.md",
    type: "note",
    eleventyComputed: {
        title: data => (data.title || data.page.fileSlug),
        backlinks: (data) => {
            const notes = data.collections.notes;
            const currentFileSlug = data.page.fileSlug;

            let backlinks = [];

            // Search the other notes for backlinks
            for(const otherNote of notes) {
                const noteContent = otherNote.template.frontMatter.content;

                // Get all links from otherNote
                const outboundLinks = (noteContent.match(wikilinkRegExp) || [])
                    .map(link => (
                        // Extract link location
                        link.slice(2,-2)
                            .split("|")[0]
                            .replace(/.(md|markdown)\s?$/i, "")
                            .trim()
                    ));

                // If the other note links here, return related info
                if(outboundLinks.some(link => caselessCompare(link, currentFileSlug))) {

                    // Construct preview for hovercards
                    let preview = noteContent.slice(0, 240);

                    backlinks.push({
                        url: otherNote.url,
                        title: otherNote.data.title,
                        preview
                    })
                }
            }

            return backlinks;
        }
    }
}

and what I tried to do :

            // Search the other notes for backlinks
            for(const otherNote of notes) {
                const noteContent = otherNote.template.frontMatter.content;
                
                // importing description in the otherNote frontmatter
                const currentDescription = otherNote.template.frontmatter.description;
                
                […]
                
                // If the other note links here, return related info
                if(outboundLinks.some(link => caselessCompare(link, currentFileSlug))) {

                    // Construct preview for hovercards
                    let preview = noteContent.slice(0, 240);
                    // passing the description tag
                    let description = currentDescription;

                    backlinks.push({
                        url: otherNote.url,
                        title: otherNote.data.title,
                        description,
                        preview,
                    })
                }

And of course it don’t works as intended, it trows 3 types of errors at me, tell me I don’t understand template.frontmatter (which is true, I don’t understand it and didn’t found it in eleventy documentation), so here I am : could you please help me through this ?

It’s OK if you don’t but I really sucks in js and programming in general (I only don’t suck at CSS I guess), it’s my first attempt at really adapting a theme and I’m close to lose my mind :’) (no, I’m not, it’s just frustrating to not get it).

If needed, my repository is here https://codeberg.org/yazae101/yazae.garden, but I really think it’s my understanding of the piece of code below who is the problem.

Have a great day,

Yazae

Nevermind, I found my problem :

                    backlinks.push({
                        url: otherNote.url,
                        title: otherNote.data.title,
                        description: otherNote.data.description, //MY CODE
                        preview
                    })

just adding the description like any other item in eleventy worked, without trying to touch the other part of the code. I feel very dumb but it works !

sorry for the bother,

Yazae
