The README grew a section per feature and is a good reference, but nothing said where to begin. docs/wiki now has a getting-started page, a guide that walks through one day with the workspace and explains each part where it comes up, and a page per part of the app, each with screenshots of what it describes. Three pages are read out of the code rather than written, so they cannot drift from it: the keys and commands from Help.svelte and commands.ts, the same lists `:help` draws; the settings from .env.example, which gains a heading for the vault, trash and history settings so they no longer sit under mail; and the API from the README's table. `make wiki` writes them, and `--check` fails when one is stale or a link between pages leads nowhere. `--publish` lays the pages out for a GitHub wiki: links without `.md`, images beside them, `[[` escaped so the wiki does not take a command's help text for a link to a page. The screenshots are taken by `make screenshots`: the debug binary on a temporary data directory, with a password made up for the run, filled with an example workspace over the API, and a headless Chromium driven over the DevTools protocol through the views the docs show. Nothing outside the temporary directory is touched but docs/images, and the pictures are cut to 256 colours, a third of their size, which a dark UI does not show. The README opens with the banner, a CI badge, the guide, the features grouped by what they are for, and six of the screenshots.

# Deploying
|
|
|
|
The workspace is one binary with the frontend inside, and one data directory.
|
|
It needs no database server and no runtime on the host.
|
|
|
|
## On a server
|
|
|
|
1. Build it: `make build` makes `target/release/narl-workspace`.
|
|
2. Copy the binary and a `.env` to the server. Set `WORKSPACE_USER`,
|
|
`WORKSPACE_PASSWORD` and `WORKSPACE_SECRET`; the server will not start with
|
|
the examples from `.env.example`.
|
|
3. Put a reverse proxy that terminates TLS in front of `WORKSPACE_BIND`, and
|
|
set `WORKSPACE_SECURE_COOKIE=1`.
|
|
4. Keep `WORKSPACE_DATA_DIR` safe. It is the whole state: the database and the
|
|
uploads.
|
|
|
|
The proxy must:
|
|
|
|
- pass the `Host` header through unchanged, because a write that a browser says
|
|
came from another origin is refused;
|
|
- allow request bodies as large as `WORKSPACE_MAX_UPLOAD_MB`;
|
|
- not weaken the security headers the app sends (`Content-Security-Policy`,
|
|
`Referrer-Policy: no-referrer` and the rest).
|
|
|
|
`GET /api/health` answers without a login, for a supervisor. `SIGTERM` gives
|
|
requests in flight eight seconds to finish.
|
|
|
|
## Docker
|
|
|
|
```sh
|
|
cp .env.example .env # set WORKSPACE_USER, WORKSPACE_PASSWORD, WORKSPACE_SECRET
|
|
docker compose up -d --build
|
|
```
|
|
|
|
The image builds the frontend with bun and the binary with cargo, then ships
|
|
only the binary on `debian:trixie-slim`, running as an unprivileged user. The
|
|
database and uploads live in the `diary-data` volume. Keep
|
|
`COMPOSE_PROJECT_NAME=narl-diary` if you rename the directory, or compose looks
|
|
for the volume under a new name and finds an empty one.
|
|
|
|
The port is published on `127.0.0.1:4242` only. To serve it through traefik,
|
|
copy `compose.override.yml.example` to `compose.override.yml` and set the host.
|
|
It joins the external `narl` network, drops the published port, and sets
|
|
`WORKSPACE_SECURE_COOKIE=1`.
|
|
|
|
## Sessions and security
|
|
|
|
- Every signed-in browser is a row on the server. `:sessions` lists them,
|
|
`:sessions rm <n>` signs one out and locks the vault, and `:logout!` signs
|
|
out every one.
|
|
- Changing `WORKSPACE_SECRET` or `WORKSPACE_PASSWORD` also signs everyone out.
|
|
- Wrong passwords are answered more slowly each time, up to 30 seconds. A
|
|
browser that has logged in before is slowed only by its own mistakes.
|
|
- With `WORKSPACE_SECURE_COOKIE=1` the cookie is `Secure` and `__Host-`
|
|
prefixed, and every answer carries HSTS for a year.
|
|
- Uploads are only served as types that cannot run in the browser.
|
|
|
|
See [Configuration](Configuration.md) for every setting.
