Line is a fast, quiet, local-first journaling app.
Every thought is a line. No friction, no clutter, no backend.

• 💾 Local-first (IndexedDB)

• ✏️ One line = one thought
• 🌗 Light & dark themes
• 📤 Export to Markdown / JSON

Nothing else.

Tech Overview

Line follows a layered, maintainable architecture:

src/
  app/       → controllers, coordination logic
  domain/    → pure business logic (Entry, JournalView)
  infra/     → persistence (IndexedDB)
  ui/        → DOM rendering & behavior
  utils/     → small helpers

CSS is split into tokens, base, layout, components, and themes.

Development

Start a dev server

Line requires an HTTP context (PWA + service worker):

npx serve .
# or
deno task start

Then open:

http://localhost:8000

(or whatever port your dev server uses)
