The plan

• /secret presents a form
• you enter a UUID there
• the page saves it to localstorage and requests the given file
• then reads its name and redirects you to a page with that name

Notes link to a secret note by its name, not its UUID. Of course, that means that GitHub will return a 404 page:

• the 404-page requests the page by name from the API, providing the list of UUIDs it knows
• the finds the files with those UUIDs and scans all links going out of them to find a note with the given name
• if it fails, it sends back a 404
• otherwise it returns the page

So I need 3 parts:

• snlx.net/secret that saves the UUID
• snlx.net/404.html that reads it and makes the request
• GET api.snlx.net/find?name=...&among=...,...

Tweaking what I have

• The links to private notes were being replaced with UUIDs
• The note names were lost in secret notes

Implementing the server logic

I'm writing it AFTER the actual logic, so I'll just link the current version and say that I want to refactor it. Eventually, now I just need to get the rest of the system working :)

The secret page

404

Eleventy tried to make it hard by creating 404/index.html instead of 404.html. Fortunately, there's a solution in their docs, you simply

---
permalink: 404.html
---

I also want to change the logo colors to something orange when a secret note is loaded, that can be done with element.style.setProperty("--var", "val").
