Implementation Overview

Step 1: XML → Markdown conversion (scripts/convert-xml.mjs)

Note: Steps 1–3 are one-time setup scripts, not part of the build pipeline.

Run:

node scripts/convert-xml.mjs                    # convert only
node scripts/convert-xml.mjs --download-images  # convert + fetch all images

What it does

1. Parses XML using fast-xml-parser (handles CDATA, namespaces).
2. Builds an author map from <wp:author> entries: email → display name.
3. Processes each post and page item:
   • Resolves the author display name via the author map.
   • Pre-processes WordPress [caption] shortcodes → plain <img> with alt text.
   • Rewrites Squarespace CDN image URLs to local /images/FILENAME paths.
   • Converts HTML → Markdown using turndown.
   • Writes a .md file with YAML frontmatter.
4. Skips attachment items (images are embedded in content and handled inline).
5. Writes content/image-manifest.json mapping every unique CDN URL to its local filename.

Frontmatter fields

Field	Source	Notes
title	<title>
date	<wp:post_date>	ISO date, truncated to YYYY-MM-DD
author	<dc:creator> → author map	Display name resolved from email
status	<wp:status>	publish or draft
type	<wp:post_type>	post or page
oldPermalink	<link>	Original relative URL — used for redirect rules
postName	<wp:post_name>	Original WP slug (may include path)
excerpt	<excerpt:encoded>	Only present when non-empty

Output filename conventions

• Posts: content/posts/YYYY-MM-DD-<last-slug-segment>.md
• Pages: content/pages/<slug>.md

The last path segment of <wp:post_name> is used as the slug.

Image handling

• All <img src="..."> URLs in content are collected and deduplicated (by URL without query string).
• Each gets a local filename derived from the last path segment of the CDN URL.
• The HTML is rewritten with local paths before HTML→Markdown conversion, so the Markdown references /images/FILENAME.
• content/image-manifest.json maps CDN URL → { localPath, filename, downloadUrl }.
• Actual file downloads happen only with --download-images (supports one redirect hop).

---

Step 2: Content reorganization (scripts/reorganize-content.mjs)

Moves Markdown files into section subdirectories and adds a section frontmatter field. Run once, after convert-xml.mjs. The section assignment uses the first path segment of oldPermalink for posts, and exact oldPermalink matching for pages.

---

Step 3: Old permalink redirects

The oldPermalink frontmatter field contains the original Squarespace URL path (e.g. /nyheter/2013/10/6/nye-riddere-kommandrer-og-storkors). This enables a redirect map to be generated if the new URL structure differs.

Planned: A script or Next.js next.config.ts redirect generator that reads all Markdown frontmatter and emits redirects() entries mapping oldPermalink → newPath.

Step 3: Next.js rendering

Tech stack

Layer	Choice
Framework	Next.js 16 App Router, static export (SSG)
Markdown parsing	gray-matter (frontmatter) + remark + remark-html
Styling	SASS — src/css/main.scss (no Tailwind)
Fonts	next/font/google — Cormorant Garamond + Cormorant SC

URL → content mapping

/nyheter/:slug	posts/nyheter/YYYY-MM-DD-{slug}.md
/historierogmyter/:slug	posts/historierogmyter/YYYY-MM-DD-{slug}.md
/den-gyldne-gris-orden	pages/den-gyldne-gris-orden/index.md
/den-gyldne-gris-orden/:slug	pages/den-gyldne-gris-orden/{slug}.md
/anno-1899	post list from posts/den-hviide-knap/

Old Squarespace flat URLs are redirected in next.config.ts (redirects()).

Header

Logo image: public/images/hm-grisen-sign.png (downloaded from Squarespace CDN). Tagline: the full royal proclamation from the live site. Nav: CSS-only hover dropdowns matching live site structure.

Dependencies added

gray-matter	Frontmatter parsing at build time
remark + remark-html	Markdown → HTML
sass	SCSS compilation

Known content quirks to handle in rendering

1. Gallery images — multiple <img> tags with no captions appear inline in Markdown. A custom renderer could display them as a grid.
2. <br> /   artefacts — Squarespace content sometimes contains empty paragraphs and non-breaking spaces; rendering should collapse these gracefully.
3. Some posts have no content — only a title and metadata (e.g. very old posts that were images-only on Squarespace).
4. Draft posts are included in the output — filter by status: publish if needed.
