internal/httpapi/notes.go exposes:
- GET /api/notes list summaries {id, title, updated_at}
- GET /api/notes/{id} full {id, title, content, updated_at}
- PUT /api/notes/{id} create/update; ?base=<unix> for
optimistic-locking conflict detection
- DELETE /api/notes/{id} remove; ?base=<unix> guards against
deleting a row modified after the
client last saw it
Backed by tenant.FS so all reads/writes go through the per-user
sandbox — path traversal is rejected at parse time (regex slug)
and again by os.Root inside the FS layer.
On-disk format is plain Markdown: first line `# Title`, rest is
content. grep / cat / vim still produce a usable view of raw
files. Title round-trips through composeNote/splitTitle.
Conflict semantics: when the client supplies ?base=<unix>, the
server compares against the file's mtime. If the file is newer,
respond 409 with the current note body so the client can present
a merge UI. Same logic on DELETE returns 409 alone.
cmd/librenotes/serve.go grows a tenantPool that memoises FS
handles per user id; defer-closes them on shutdown.
Tests cover: full CRUD round-trip, cross-tenant isolation,
unauthenticated 401s, invalid IDs (regex rejection), and the
conflict path with a real mtime advance.

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.
