cmd/librenotes/web/public/sync.js drives the offline-online
reconciliation flow against the notes REST API:
- start(): registers online/offline window listeners, runs an
initial syncOnce() if currently online.
- syncOnce(): push() then pull(); emits "librenotes:sync-state"
events with state in {online, offline, syncing, synced, error}.
- push(): walks notesCache.pending() (rows with dirty=1, including
tombstones). PUTs use ?base=<synced_at> for optimistic locking
and DELETEs use the same. The notes API returns 409 with the
current server body on conflict; sync.js stashes the pair in
conflictsById and dispatches "librenotes:sync-conflict" so the
app shell can render a resolution dialog.
- pull(): GETs the summary list, refetches any row whose server
updated_at exceeds the local synced_at (or that is missing
locally), and stamps it as cleanly synced. Skips locally-dirty
rows so push's conflict path stays authoritative.
- resolveConflict(id, "local"|"remote"|"merge", merged): replays
the user's choice. "local" and "merge" PUT with the latest
server base so the second attempt accepts; "remote" overwrites
the local cache with the server copy.
app.html now includes a sync-state badge in the header and a
<dialog> for conflict resolution wired to the events. app.js
calls notesSync.start() on load and routes dialog clicks back to
resolveConflict. The dialog uses native <dialog>.showModal(),
which all current target browsers support.
style.css adds badge colour states (syncing/synced/offline/error)
and a two-column conflict layout that collapses on narrow widths.
Closes #23.

librenotes
Cloud-native, multi-tenant notes application. A fork of Notesium extended with authentication, per-user data isolation, sync, and PWA support so it can run as a hosted service at librenot.es.
Features
- Markdown notes with bi-directional links (Zettelkasten / evergreen notes)
- Embedded web app — no Electron, no Node runtime, single static binary
- Multi-tenant backend with magic-link authentication (in development)
- Offline-capable PWA with background sync (planned, Phase 4)
Build
Requires Go 1.20 or later.
go build ./cmd/librenotes
This produces a librenotes binary in the current directory. The web
frontend and shell completion are embedded into the binary at compile
time, so no extra files are needed at runtime.
A Makefile with build, test, run, and clean targets is provided
for convenience:
make build
make test
Run
./librenotes web --notes-dir ~/notes
See ./librenotes help for the full command list.
Development setup
A Nix flake provides a reproducible development environment with Go,
build tools, and the project CLIs. Use the plain dev shell for a
non-sandboxed Go toolchain:
nix develop .#dev
Alternatively, build a Docker-based dev environment:
docker build -f Dockerfile.dev -t librenotes-dev .
docker run --rm -it -v "$PWD:/workspace" librenotes-dev
The repository layout follows the standard Go project structure:
cmd/librenotes/ Binary entry point
internal/notesium/ Core notes package (forked from Notesium)
internal/notesium/web/ Embedded frontend assets
The Go module path is git.librete.ch/public/librenotes.
