Introduction

What is VaultPress?

VaultPress turns an Obsidian vault into a documentation site.

Keep writing in Obsidian as usual. Run pnpm generate to sync notes into content/, then preview or deploy the site. The stack is Next.js + Fumadocs, with Obsidian wikilinks, embeds, callouts, Mermaid, and math.

Setup

Copy .env.example to .env and configure:

# Required for pnpm generate and pnpm obsidian
OBSIDIAN_VAULT_PATH="/path/to/your/vault"

# Optional
SITE_LANGUAGE=en
GENERATE_INCLUDE=fleeting,permanent,literature
SITE_PROTECT_PASSWORD=your-password

OBSIDIAN_VAULT_PATH is not read when building site links — the server never accesses your local filesystem for page actions.

Workflow

Obsidian vault → pnpm generate → content/ → pnpm dev → site

1. Edit notes in your Obsidian vault
2. Run pnpm generate to convert Markdown into MDX under content/
3. Run pnpm dev to preview locally at http://localhost:3000

pnpm generate only reads your vault and writes to content/ — it does not modify notes in Obsidian.

Commands

Site language

Set SITE_LANGUAGE in .env:

SITE_LANGUAGE=en   # English (default)
SITE_LANGUAGE=cn   # 简体中文

Restart the dev server after changing it. This changes the site UI only — your note content is not translated.

Page features

Each documentation page includes:

• Tags — From frontmatter tags (string or list), shown below the description
• Copy Markdown — Copy the processed Markdown for the page
• Open menu:
  • Open in Obsidian — obsidian://open?file=… using the page's public relative path (.mdx → .md). Opens the note in local Obsidian when your vault mirrors the generated structure.
  • Open in GitHub — Link to the page source under content/ (configure lib/shared.ts → gitConfig for your repo)
  • View as Markdown — Open the raw Markdown endpoint for the page

Protected pages

Protected pages use shared-password access control. They are not encrypted: generated MDX still lives in content/ like any other page. The site only withholds the body and some exports until a visitor proves they know SITE_PROTECT_PASSWORD.

Mark a note with frontmatter:

protected: true

Obsidian may export this as a string (protected: 'true') — both are supported.

Set the shared password in .env (never commit this value):

SITE_PROTECT_PASSWORD=your-password

Restart the dev server after changing it. One password unlocks all protected pages for that browser session.

Viewing protected pages

Before unlocking, protected pages stay in the sidebar but their bodies are gated; they are hidden from search, graph, and Markdown endpoints. If someone guesses the URL, they can open the page shell directly — but still cannot read the body without the password, for example:

/permanent/202606061435

The page title, description, and tags remain visible even before unlock. A password form appears in the body only — Copy Markdown, View as Markdown, and the Open menu stay hidden until unlocked.

After a correct password, the browser stores an HttpOnly cookie for about 30 days. Requires server deployment (pnpm build + pnpm start, or Vercel) with HTTPS in production — not static export.

Security model

What this scheme is good for

• Keeping protected note bodies out of casual reading, search, and Markdown export (sidebar links remain visible)
• A simple gate when the site is public but a few pages should need a shared secret
• Pairing with a private repository so content/ is not world-readable on GitHub

What it does not protect against

• Repository or build access — content/*.mdx contains the full source; anyone with repo, CI, or server filesystem access can read it without the password
• URL guessing — if someone knows your folder structure, they may find the page URL and see its title, description, and tags before unlock; the body and Markdown exports remain blocked
• Metadata leakage — title, description, and tags are shown before unlock
• One password for everything — there are no per-page or per-user passwords; sharing the password shares access to all protected pages
• Cookie scope — one successful unlock grants access to every protected page until the cookie expires
• Brute force — /api/protected-auth has no built-in rate limiting; use a strong password and HTTPS
• True secrecy — this is access gating, not encryption, audit logging, or account-based authorization

Practical guidance

• Use a long, unique SITE_PROTECT_PASSWORD and keep .env out of version control
• Deploy over HTTPS so the HttpOnly cookie is marked Secure in production
• For highly sensitive material, do not publish it through pnpm generate; keep it only in Obsidian, or use a proper auth system instead

Directory layout

• .env — Vault path, site language, generate selection, protect password
• content/ — Generated MDX (from generate), plus hand-written pages
• app/ — Next.js pages and routes
• lib/ — Locale, Obsidian URIs, tags, protected access, shared config
• scripts/generate.ts — Vault → site generation script (read-only on vault)
• scripts/open-obsidian.ts — Opens the configured vault in Obsidian

Generation rules

scripts/generate.ts clears content/ before each run, except hand-written index.mdx and graph.mdx, so removed or renamed notes do not leave stale files.

The first interactive run shows the vault's top-level tree so you can pick folders and files to include. The choice is saved as GENERATE_INCLUDE in .env. Use pnpm generate -- --select to re-pick. In non-interactive environments, all top-level items are included by default.

Excluded from generation:

• .obsidian/ — Obsidian configuration
• templates/ — Note templates

Frontmatter handling:

• title — Uses the note's title field, then the first # heading, then the filename
• description — Uses the note's description field only; omitted if empty
• tags — Passed through from Obsidian frontmatter; normalized to a string array for display
• protected — When true (or 'true'), gates the page body behind SITE_PROTECT_PASSWORD (not encryption)

Graph View

The Graph View page shows an interactive graph of site pages and wikilink connections. Each node is a page; edges are internal links. Click a node to open that page. Protected pages appear only after unlocking.
