New Tab Notepad for Chrome

Features

• Persistent notepad on the "New Tab" page using Chrome's storage API.
• Syncs across your Chrome browsers; notes too long for the sync quota automatically fall back to device-local storage.
• Live-updates across open tabs, so a stale tab never clobbers newer text.
• Dark mode, following the system setting.
• Options for font size and spellcheck (right-click the toolbar icon → Options); clicking the toolbar icon opens a new tab.

Tip: Chrome hides the bookmarks bar on custom new-tab pages. Press ⌘⇧B (Mac) or Ctrl+Shift+B (Windows/Linux) to always show it.

Development

• npm test — behavioral tests that drive tab.js against a stubbed chrome.storage and DOM. No dependencies needed.
• npm run lint — ESLint via npx. Both run in CI on every push and PR.
• Icons are rendered from icon.svg: docker run --rm -v "$PWD":/work -w /work alpine:3 sh -c 'apk add --no-cache rsvg-convert && for s in 16 48 128; do rsvg-convert -w $s -h $s icon.svg -o icon$s.png; done'

Releasing

Bump version in manifest.json, zip the extension files, and upload by hand at the Chrome Web Store developer dashboard:

zip -X new-tab-notepad.zip manifest.json start-page.html new-tab.css tab.js background.js options.html options.js options.css icon16.png icon48.png icon128.png

Todo

• Icon vectorized — icon.svg reproduces the original icon128.png pixel-for-pixel when exported, and now also renders the 16/48px sizes
• Better Chrome Extension Javascript — promise-based storage, input events, cross-tab sync
• Tests, lint — node --test behavioral suite + ESLint, run in CI.
