temp.md Temporary Preview for Yank Note

Publish the current Yank Note document to an unlisted, expiring temp.md preview URL.

Yank Note's built-in Share Preview is ideal on the same local network. This extension adds an explicitly opt-in internet handoff for feedback, remote review, and cross-device testing without configuring a permanent deployment.

Features

• Exports the current Markdown document as self-contained HTML.
• Inlines local images using Yank Note's own export pipeline.
• Creates an unlisted temp.md URL that normally expires seven days after the last publish or update.
• Updates the same URL without exposing the update capability.
• Copies, opens, claims, or revokes the preview from the Yank Note status bar.
• Stores a separate preview record for each document.
• Refuses to publish encrypted documents.

Install

Once accepted into the Yank Note Extension Registry, install temp.md Temporary Preview from Tools → Extension Center.

For development or manual installation:

npm install
npm run build

Place this package in the Yank Note extension directory and enable it from the Extension Center. Yank Note's extension development guide also supports:

npm run link-extension
npm run dev

Usage

1. Open a Markdown document.
2. Select temp.md → Publish temporary preview in the status bar.
3. Review and accept the upload disclosure.
4. Share the copied URL.

Use Update existing preview to replace the content at the same URL. Use Revoke preview to delete it immediately.

Privacy and security

Publishing is never automatic. Before each publish or update, the extension explains that the rendered HTML and inline local images will be uploaded to temp.md and accessible to anyone who has the unlisted URL.

The extension stores the scoped update/revoke capability in Yank Note's local extension storage. It is not an account token and applies only to one preview, but it should still be treated as a secret. It is never placed in the public URL, rendered document, telemetry, or logs.

The extension exports one self-contained index.html file. The temp.md per-file limit is 10 MB, so documents whose inline images push the export above that size are rejected before upload.

Development

npm install
npm run check

The API workflow has unit coverage for create, same-link update, skipped uploads, structured errors, size validation, and revoke.
