Add offline editing: local persistence, PWA shell, offline resolution (#38)
Editing continues without a connection and merges conflict-free on
reconnect (ADR 0003, realtime-collaboration.md §Offline).

- y-indexeddb mirrors every opened page's Y.Doc to IndexedDB, sharing the
  document with the collab provider. The local copy is discarded when the
  page is left after a successful server sync (bounding IndexedDB growth)
  and kept otherwise so offline edits survive to the next visit.
- vite-plugin-pwa service worker precaches the app shell (build assets only)
  with a navigation fallback; `/api` and `/collab` are denylisted and there
  is no runtime caching, so API responses are never cached or poisoned.
- Offline page resolution WITHOUT caching API responses: the app itself
  persists the small metadata it needs to reopen a visited page (page/pond
  ids + slugs, bounded LRU in localStorage) and the last signed-in user, so
  after an offline tab reload the app stays signed in, resolves the page, and
  restores its content from IndexedDB. Both are revalidated when the network
  returns (a 401 clears the cached user).
- Local-only UI: a banner when there are edits held only on this device
  (provider `onUnsyncedChanges`), de + en.

Tests: `page-cache` unit test (remember/recall + bounded eviction); a new
`offline` e2e pack (validated locally against the full stack and wired into
CI): edit, reload while offline (shell from the SW, content from IndexedDB),
assert an API call fails offline (no SW API caching), then reconnect and a
second client converges. The e2e static server serves `.webmanifest`.

Dorfteich

Dorfteich is an open-source wiki system built around ponds (German: Teiche) — self-contained wiki spaces that people and teams organize freely with hierarchical labels, directories, and Obsidian-style page relations. Pages are edited in a collaborative WYSIWYG editor with live cursors and offline support.

Key features

  • Real-time collaboration — multiple people edit the same page simultaneously; everyone sees the other participants' cursors and input live. Offline edits merge conflict-free on reconnect (CRDT-based).
  • Ponds — isolated wiki spaces with their own members, permissions, fonts, and page organization. Every registered person gets a personal pond.
  • Flexible organization — hierarchical labels, free page ordering, [[wikilinks]] with backlinks. A classic page tree is possible but never enforced.
  • Fine-grained permissions — roles (Site Admin, Pond Admin, Editor, Reader, Public) can be granted per pond, per label, or per page; the most specific setting wins.
  • Import & export — Markdown as the primary exchange format, plus best-effort structural import from Word/OpenOffice and export to Word/OpenOffice/PDF.
  • Plugins — sandboxed extensions (custom blocks, styles, page tools) installable at runtime without redeploying the instance.
  • Self-hosting first — a single docker compose up plus a guided first-run setup wizard yields a working instance.

Repository layout

Path Contents
docs/architecture/ Architecture documentation: ADRs, data model, permission model, collaboration and plugin concepts, deployment and operations
apps/ Application packages (web frontend, API server, collaboration server) — created as implementation proceeds
packages/ Shared packages (types, permission logic, plugin SDK)
deploy/ Docker Compose stacks and deployment tooling

Development

Requirements: Node.js ≥ 22 and pnpm (npm install -g pnpm).

pnpm install        # install all workspace dependencies
pnpm lint           # ESLint + Prettier check across the repo
pnpm typecheck      # TypeScript --noEmit in every package
pnpm test           # Vitest in every package
pnpm build          # build every package (dependency order)

The workspace packages live under apps/ (web, api, collab) and packages/ (shared). Shared logic goes into packages/shared and is imported as @dorfteich/shared — never copy code between apps.

Status

The project is in the architecture and backlog phase. Implementation stories are tracked as issues in this repository. Start reading at docs/architecture/README.md.
