Valeon

Publish and sync posts to the Valeon author dashboard from your vault. Works on desktop and mobile.

Valeon is an invite-only writing platform. If you're not already an author, read How to contribute and submit the application form linked there — accepted authors receive an invite email to set up a dashboard account, at which point you can publish either via the web dashboard or with this plugin.

Install

Open Obsidian → Settings → Community plugins → Browse → search for "Valeon" → Install → Enable.

Setup

1. Sign in to the Valeon author dashboard and open Settings → API Keys. Create a new token and name it for the device (e.g. "iPhone Obsidian"). Copy the token — it is only shown once. You can revoke this token at any time from the same page.
2. In Obsidian, open Settings → Valeon publishing and paste the value into the API token field. That's the only setting authors configure — the plugin always talks to the production Valeon backend.
3. Click Test connection to verify.
4. Run Valeon: Sync template from server once. This downloads the current schema and writes _templates/post.frontmatter.template.md — the cached template that Valeon: New post uses to populate the frontmatter of new posts. Without this step, Valeon: New post will prompt you to run it; doing it up front avoids the interruption. Re-run the command any time the server's schema changes.

Folder structure

Every post lives in its own dated folder at the top level of the vault:

2026-05-21-my-first-post/
├── post.md
└── assets/
    ├── cover.png
    └── diagram.svg

The plugin only recognises this layout — YYYY-MM-DD-{slug}/post.md. Files that aren't named exactly post.md, or that live outside a dated folder, are ignored by sync, publish, lint, and reconcile.

• Create posts with Valeon: New post. It prompts for a title, derives the slug, creates the dated folder (YYYY-MM-DD-{slug}/), writes a fresh post.md pre-populated with the frontmatter scaffold from the cached schema template, and opens it for editing. You don't need to create the folder or copy a template by hand — this command does both.
• Slug is derived from the title and is part of the folder name — don't rename the folder after publishing; the plugin uses it to match local notes to their remote post.
• Place assets (images, attachments, supporting documents) inside the post's folder. The convention is a ./assets/ subfolder, but any path inside the post folder works. See Inline images & assets below.

Commands

Command	What it does
Valeon: New post	Prompts for a title, creates YYYY-MM-DD-{slug}/post.md from the cached template, opens it.
Valeon: Lint post	Validates the current note against the cached server schema.
Valeon: Slugify tags (current file)	Kebab-cases all tag values in frontmatter.
Valeon: Slugify tags (vault)	Same, vault-wide.
Valeon: Publish	Lints, uploads new local assets, pushes to the dashboard. First publish creates and publishes; subsequent calls update the draft buffer and republish.
Valeon: Pull post (published)	Pulls the live published body + frontmatter into the local note. Downloads any new media into ./assets/.
Valeon: Pull post (draft buffer)	Same, but prefers the draft buffer.
Valeon: Pull metadata	Refreshes server-derived fields (publishedAt, readingTime, wordCount, audioUrl) in the valeon: block. Doesn't touch the body.
Valeon: Pull metadata (vault)	Same as above, applied to every linked note in the vault.
Valeon: Sync vault	Bulk pull for every linked note where the server's updatedAt is newer than the local valeon.remoteUpdatedAt. Conflict files get auto-backed up. Report goes to _reports/.
Valeon: Sync template from server	Refreshes the schema cache and regenerates _templates/post.frontmatter.template.md.
Valeon: Reconcile vault (preview)	Dry-run for backfill: matches local notes to remote posts and writes a report.
Valeon: Reconcile vault (apply)	Writes the valeon.postId into every matched note. Idempotent.
Valeon: Restore vault from server	Downloads every post you own from the server into a fresh folder structure.
Valeon: Open in dashboard	Opens the linked post's editor URL in your browser.

First-time backfill

If you've been publishing via the web dashboard and your vault already has post files without a valeon.postId in their frontmatter, run a one-time backfill so the plugin can match them to their remote counterparts:

1. Settings → paste token, click Test connection.
2. Run "Valeon: Sync template from server" once.
3. Run "Valeon: Reconcile vault (preview)".
4. Open the latest file in _reports/ — verify the matches look right.
5. Run "Valeon: Reconcile vault (apply)".

All matched posts now have valeon.postId in frontmatter and are considered "linked". Future edits flow through Publish.

Frontmatter conventions

The plugin manages a valeon: block at the end of frontmatter:

valeon:
  postId: k7abc...
  publishedAt: 2026-05-17T03:21:00Z
  lastPushedAt: 2026-05-17T04:00:00Z
  lastPushedBodyHash: 9f8e7d...
  remoteUpdatedAt: 2026-05-17T03:21:00Z
  schemaVersion: 1
  media:
    "abc123...": kg2xyz...

This block is stripped before sending to the server. It is purely local state. obsidian-linter's yaml-key-sort rule accepts unknown keys at the end of frontmatter, so this co-exists with the existing ordering convention.

Recommended companion: Linter plugin

The Valeon plugin ships its own Valeon: Lint post command, but it does a different job than Victor Tao's Linter plugin — the two are complementary, not redundant:

• Valeon: Lint post validates your frontmatter against the live server schema — required keys, allowed category enums, slug pattern, excerpt length, etc. It does not modify the file; it surfaces errors so publish will succeed.
• Victor Tao's Linter formats YAML and body — sorts keys, normalises timestamps, escapes special characters, trims whitespace, enforces heading and list style. It does not check whether your post is valid for Valeon; that's the job of the validator above.

Install Victor Tao's Linter plugin (community plugin id obsidian-linter) and enable Lint on save. The rules below align with the frontmatter shape Valeon expects — set these via Linter's settings tab or paste into .obsidian/plugins/obsidian-linter/data.json under ruleConfigs.

YAML key sort — keep frontmatter keys in the order Valeon expects:

title
pubDate
updatedDate
excerpt
cover
coverAlt
author
series
featured
tts
podcast
categories
tags
canonical

Set priority keys at start of YAML = on, sort order for other keys = Ascending Alphabetical. The plugin's valeon: block is treated as an "other key" and stays at the end.

YAML timestamp — manage pubDate (created) and updatedDate (modified):

Setting	Value
date-created-key	pubDate
date-created-source-of-truth	file system
date-modified-key	updatedDate
date-modified-source-of-truth	file system
format	YYYY-MM-DD[T]HH:mm:ss[Z]
convert-to-utc	on
update-on-file-contents-updated	never

Other YAML rules to enable (purely hygiene, no Valeon-specific config): add-blank-line-after-yaml, dedupe-yaml-array-values, escape-yaml-special-characters, format-tags-in-yaml.

Folders to ignore — add _templates so the linter doesn't mangle the post template that Valeon: Sync template from server writes.

The remaining list / heading / spacing rules are general markdown hygiene — pick whatever you prefer; they don't conflict with Valeon's requirements.

Inline images & assets

Place every image, attachment, or other supporting file inside the post's own folder — files outside the folder are not uploaded. The convention is a ./assets/ subfolder, but any path inside the post folder works:

![architecture diagram](./assets/diagram.svg)
![[assets/photo.jpg]]

Both standard markdown and Obsidian wiki-link syntax are supported; the plugin normalises wiki-links to standard markdown during push.

Cover image: declare it in frontmatter, pointing at a path inside the post folder. The cover is validated by lint before publish:

cover: ./assets/cover.png
coverAlt: A clay model of the new logo on a wooden desk.

What the plugin does on publish:

• Reads each referenced asset, computes sha256, dedupes against the local valeon.media: map.
• Uploads new assets; writes the sha256 → storageId mapping back into frontmatter.
• Rewrites the transport copy of the markdown to /m/{storageId} — the original file in your vault is untouched.

Supported formats: any MIME type the server schema allows (schema.media.allowedMimeTypes). Lint reports anything unsupported before the upload attempt — run Valeon: Lint post if you want to check ahead of time.

On pull: /m/{storageId} references get downloaded into ./assets/ and rewritten back to relative paths automatically.

Linking between notes

Assets vs cross-post links. Links inside the same post folder are treated as assets and uploaded; everything else falls under cross-post behaviour:

• Links inside the same post folder (./assets/x.png, ./supplementary.md) → uploaded as assets, rewritten to /m/{storageId} in the transport copy.
• Cross-post links (see below) → translated to a stable valeon:post:{convexId} URI on push so the link survives folder renames and slug changes.
• External URLs (https://example.com/...) → untouched.

Wiki-links ([[note]], ![[asset]]) work the same way — they're converted to standard markdown during push and follow the same inside/outside-folder rule.

Cross-post references

You can link from one Valeon post to another. The plugin handles translation to a stable identifier on push, and back to something human-readable on pull, so you keep writing normal markdown and the link survives folder renames, slug changes, and editing the same post from the web dashboard.

To write a cross-post link, use one of these two forms:

For my own posts, point at the other post.md file:
[my earlier piece](../2026-04-12-warmup/post.md)

For another author's post (or your own via canonical URL),
paste the blog URL straight from the address bar:
[Sarah's essay](https://valeon.blog/2026/04/15/sarahs-essay)

Obsidian's autocomplete will offer the dated folder name as you type ../, which keeps the first form fast. The canonical-URL form is the only way to reference posts not in your vault.

Both forms support #anchor fragments and ?query strings, preserved end-to-end:

[the intro section](../2026-04-12-warmup/post.md#intro)
[via card](https://valeon.blog/2026/04/15/sarahs-essay?ref=card)

What happens on publish. Valeon: Publish translates either form into a stable valeon:post:{id} URI before sending the body to Convex. Your local post.md file is not modified — only the transport copy that lands in the database. The blog's render pipeline resolves the URI to /YYYY/MM/DD/{slug} at render time, so the rendered link always points at the target's current canonical URL even if its slug or publication date changes later.

What happens on pull. Valeon: Pull post and Valeon: Sync vault reverse the translation, writing the most useful local form back into your post.md:

Referenced post state	What lands in your local file
Owned by you, already in this vault	../folder/post.md — clickable inside Obsidian
Foreign, already published	https://valeon.blog/YYYY/MM/DD/slug — clickable in the browser via Obsidian's link handler
Foreign, still draft (or archived)	valeon:post:{id} left verbatim — not clickable in Obsidian, but rewrites itself to a real URL on the next pull once the target publishes

You'll occasionally see the third row if you reference a friend's draft. It's harmless; the URI round-trips on the next publish, and the blog renders a "broken link" 404 in the meantime until the target ships.

Lint catches problems before publish. Valeon: Lint post (run implicitly by Valeon: Publish) flags these cases as errors and blocks the push:

• Folder-path form points at a file that doesn't exist in your vault. Either the path is wrong, or the target hasn't been pulled yet.
• Folder-path form points at a file with no valeon.postId in frontmatter. The target exists locally but hasn't been linked to Valeon — publish it first (or run Valeon: Reconcile vault).
• Canonical URL doesn't match any published post. The slug in the URL doesn't exist on the server, or the post is still a draft. (Draft slugs aren't reachable until publication; the URL form only works for published posts.)

Editing from the web dashboard. The author dashboard's editor supports the same cross-post mechanism — /post slash command, a search-posts mode in the Cmd+K link dialog, and paste-detection of canonical blog URLs. Posts edited in the dashboard produce the same valeon:post:{id} wire form, so if you pull one of those posts into Obsidian afterwards you'll see the local equivalents (folder paths or canonical URLs) in the file.

Conflict handling

Pull post shows a modal when local has unpushed edits AND remote has newer changes. Three options:

• Save local as backup & pull: writes post.local-backup-<ts>.md next to post.md, then pulls.
• Force pull, discard local: overwrites without backup.
• Cancel: no changes.

Sync vault always uses backup-and-pull on conflict.

Development

The production API and dashboard URLs are baked into the build at compile time. Override them for local development against a non-production Valeon backend:

set -x VALEON_API_BASE_URL "https://your-dev.convex.site"
set -x VALEON_DASHBOARD_BASE_URL "https://author.dev.valeon.blog"
bun install
bun run dev
