-## RSS-Reader [WIP]
+# RSS Reader
 
-# Diesel Setup
+A self-hosted RSS reader: a Rust/actix-web + Diesel/PostgreSQL backend with a Vue 3 single-page-app frontend. Sync feeds, read articles, and mark them as read — from your desktop or your phone.
 
-setup, first step, or when docker been and DB not found.
+## Stack
 
-`diesel setup`
+- **Backend**: Rust, actix-web, Diesel ORM, PostgreSQL, JWT auth
+- **Frontend**: Vue 3, Vite, axios
+- **Database**: PostgreSQL 18
 
-generate table
+---
 
-`diesel migration generate create_to_do_items`
+## Development setup
 
-fill up and down
+### Prerequisites
 
-`diesel migration run`
+- [Rust](https://rustup.rs/) (stable toolchain)
+- [Node.js](https://nodejs.org/) 20+ and npm
+- PostgreSQL (locally, or via Docker — see below)
+- The Diesel CLI: `cargo install diesel_cli --no-default-features --features postgres`
+  (requires `libpq`; on Debian/Ubuntu: `sudo apt install libpq-dev`)
 
-# docker
+### 1. Configure environment variables
 
-`docker exec -it 59ff8bad10c0 psql -d rss -U admin`
+Copy the example file and fill in your own values:
 
+```sh
+cp .env.example .env
+```
 
-# Create user
+`.env` is read by both the backend (via `dotenv`) and the `diesel` CLI, and is gitignored — never commit it.
-curl -X POST -H "Content-Type: application/json" -d '{"name": "mace", "email": "safemind@posteo.de", "password": "secret"}' http://localhost:8001/api/v1/user/create
 
+| Variable | Purpose |
+|---|---|
+| `DATABASE_URL` | Postgres connection string, e.g. `postgres://admin:changeme@localhost/rss` |
+| `JWT_SECRET` | Secret used to sign/verify auth tokens — use a long random string |
+| `FRONTEND_ORIGIN` | Origin allowed by CORS, e.g. `http://localhost:5173` for the Vite dev server |
+| `RUST_LOG` | Log level for `env_logger`, e.g. `info` |
+| `POSTGRES_PASSWORD` | Password for the `admin` Postgres user (used by `docker-compose.yml`) |
+
+### 2. Start PostgreSQL
+
+The simplest way during development is to run just the database container:
+
+```sh
+docker compose up postgres -d
+```
+
+This starts Postgres on `localhost:5432` with the credentials from `.env`. Alternatively, point `DATABASE_URL` at any Postgres instance you already have running.
+
+### 3. Run database migrations
+
+Migrations are embedded in the backend binary and also run automatically on startup, but you can apply them manually with the Diesel CLI (useful when generating new migrations during development):
+
+```sh
+diesel setup            # creates the database and runs existing migrations
+diesel migration run    # applies any pending migrations
+diesel migration generate <name>   # scaffolds a new up.sql/down.sql pair
+```
+
+### 4. Run the backend
+
+```sh
+cargo run
+```
+
+The API listens on `http://0.0.0.0:8001`. Backend logs respect `RUST_LOG`.
+
+### 5. Run the frontend
+
+```sh
+cd vue
+npm install
+npm run dev -- --host
+```
+
+The Vite dev server runs on `http://localhost:5173` (the `--host` flag also exposes it on your LAN so you can test from a phone) and proxies `/api` requests to `http://localhost:8001` (configured in `vue/vite.config.js`).
+
+### 6. Try it out
+
+Create a user, then log in through the UI at `http://localhost:5173`:
+
+```sh
+curl -X POST -H "Content-Type: application/json" \
+  -d '{"name": "mace", "email": "you@example.com", "password": "secret1"}' \
+  http://localhost:8001/api/v1/user/create
+```
+
+Passwords must be at least 6 characters.
+
+### Useful commands during development
+
+```sh
+# Backend
+cargo build              # compile
+cargo test               # run the test suite (needs a reachable Postgres + DATABASE_URL)
+cargo clippy             # lint
+cargo fmt                # format
+```
+
+```sh
+# Frontend (run from vue/)
+npm run test             # run Vitest component tests
+npm run lint             # eslint
+npm run format           # prettier
+```
+
+```sh
+# Inspect the dockerized database directly
+docker exec -it rss-postgres psql -d rss -U admin
+```
+
+---
+
+## Security notes
+
+- **Sessions**: login returns a JWT (`token` header) valid for 24 hours. Logging out
+  (`POST /api/v1/auth/logout`, requires the current token) bumps the user's
+  `token_version`, which immediately invalidates *all* outstanding tokens for that
+  account — there's no per-session revocation, so logging out on one device logs out
+  every device.
+- **Login rate limiting**: `POST /api/v1/auth/login` is limited to a burst of 5 requests
+  per IP, replenishing one every 2 seconds (`actix-governor`).
+- **Outbound fetches**: feed syncs and the article-reader endpoint only fetch
+  `http`/`https` URLs that resolve to public IP addresses (no loopback/private/
+  link-local, e.g. `127.0.0.1` or the `169.254.169.254` cloud metadata address).
+  Redirects are followed (up to 5 hops), but each redirect target is checked against the
+  same rules before being fetched, so a redirect can't be used to reach an internal
+  address.
+- **Stored feed content**: `<img>` tags from synced feed content are sanitized
+  (`ammonia`) down to `src`/`alt`/`title` before being stored, since they're later
+  rendered with `v-html` in the frontend.
+- **If `JWT_SECRET` or `POSTGRES_PASSWORD` are ever leaked** (e.g. committed to git),
+  rotate them in `.env` and restart the backend — rotating `JWT_SECRET` invalidates every
+  outstanding token as a side effect.
+
+---
+
+## Production setup (Docker)
+
+The whole stack — Postgres, backend, and frontend — runs via Docker Compose. The frontend is built as a static Vue bundle and served by nginx, which also reverse-proxies `/api/` to the backend container.
+
+### 1. Configure environment variables
+
+Same as in development — create a root-level `.env` from `.env.example` and fill in **strong, unique** values for `POSTGRES_PASSWORD` and `JWT_SECRET`. Set `FRONTEND_ORIGIN` to the URL the frontend will actually be served from (e.g. `http://<host-ip>:8080` or your domain), since the backend's CORS policy only allows that origin.
+
+### 2. Build and start everything
+
+```sh
+docker compose up --build -d
+```
+
+This builds three images and starts them on a shared network:
+
+- **`postgres`** — PostgreSQL 18, data persisted in the `postgres_data` volume, reachable on `localhost:5432`
+- **`backend`** — multi-stage build (compiles the Rust binary in a `rust:slim` builder, runs it in a slim `debian` runtime image); runs embedded Diesel migrations automatically on startup; listens on `0.0.0.0:8001`
+- **`frontend`** — multi-stage build (compiles the Vue app with `node:20-alpine`, serves the static bundle with `nginx:alpine`); listens on `0.0.0.0:8080` and proxies `/api/` to the `backend` service over Docker's internal network
+
+### 3. Use it
+
+- From the host machine: `http://localhost:8080`
+- From another device on the same network (e.g. a phone): `http://<host-LAN-IP>:8080`
+
+### Operating the stack
+
+```sh
+docker compose ps                  # check container status
+docker compose logs -f backend     # follow backend logs
+docker compose down                # stop everything (keeps the postgres_data volume)
+docker compose down -v             # stop and wipe all data — careful!
+docker compose up --build -d       # rebuild after pulling code changes
+docker builder prune -af && docker image prune -af  # reclaim disk used by old build layers/images
+```
+
+> Each `docker compose up --build` leaves the previous build's cache layers and images
+> behind, which adds up quickly given how much disk `cargo build` needs. Run the prune
+> command above after each rebuild (or on a cron job) to reclaim that space.
+
+### Optional: hardened deployment — isolated user + rootless Docker
+
+Anyone who can run `docker` commands effectively has root on the host (container volume mounts can reach the whole filesystem) — being in the `docker` group is root-equivalent. For a production server, it's worth confining this stack to a dedicated, unprivileged system user running its own **rootless Docker** daemon, instead of using a system-wide install or adding the user to the `docker` group.
+
+Rootless Docker runs as a completely independent daemon — separate socket and storage (`~/.local/share/docker` vs. `/var/lib/docker`) — so it coexists fine with an existing system-wide Docker install on the same host. Just make sure `DOCKER_HOST`/`PATH` point at the rootless daemon when operating on this stack, and that the ports you publish in step 4 below aren't already in use elsewhere.
+
+**1. Create the user:**
+
+```sh
+sudo adduser --disabled-password --gecos "" rss-svc
+```
+
+> The "normal" rootless Docker setup runs the daemon as a **per-user systemd service** kept alive via `loginctl enable-linger`, which depends on `systemd-logind`/D-Bus. Minimal headless images (DietPi included) often disable or strip those out — and whether re-enabling them survives the distro's own update mechanism is genuinely unclear. Rather than depend on that, the steps below run rootless Docker as an ordinary **system-level** unit with `User=rss-svc` — no logind, no D-Bus, no lingering, nothing that can be reset out from under you.
+
+**2. Install rootless Docker for that user:**
+
+```sh
+sudo apt install -y uidmap
+sudo -u rss-svc -H curl -fsSL https://get.docker.com/rootless -o /tmp/install-rootless.sh
+sudo -u rss-svc -H sh /tmp/install-rootless.sh
+```
+
+The installer detects there's no active systemd **user session** for `rss-svc` (we're not logging in interactively), so instead of wiring up a per-user service it falls back to a runtime directory under the user's home — and prints the exact paths to use, e.g.:
+
+```sh
+export XDG_RUNTIME_DIR=/home/rss-svc/.docker/run
+export PATH=/home/rss-svc/bin:$PATH
+export DOCKER_HOST=unix:///home/rss-svc/.docker/run/docker.sock
+```
+
+Use the values **the installer prints for you** (add them to `~/.bashrc` as `rss-svc` — e.g. `sudo -u rss-svc -H bash`) — this is actually convenient for us, since `~/.docker/run` is a regular on-disk directory that persists across reboots without any `tmpfiles`/`RuntimeDirectory=` trickery.
+
+Now create the system unit at `/etc/systemd/system/docker-rss-svc.service`, pointing `XDG_RUNTIME_DIR` at that same directory:
+
+```ini
+[Unit]
+Description=Rootless Docker daemon (rss-svc)
+After=network.target
+
+[Service]
+User=rss-svc
+Group=rss-svc
+Environment=PATH=/home/rss-svc/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+Environment=XDG_RUNTIME_DIR=/home/rss-svc/.docker/run
+ExecStart=/home/rss-svc/bin/dockerd-rootless.sh
+Restart=always
+RestartSec=2
+Delegate=yes
+Type=notify
+NotifyAccess=all
+KillMode=mixed
+TasksMax=infinity
+LimitNOFILE=1048576
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Then enable and start it:
+
+```sh
+sudo systemctl daemon-reload
+sudo systemctl enable --now docker-rss-svc
+```
+
+Verify it came up (as `rss-svc`, with the `.bashrc` exports loaded):
+
+```sh
+docker info
+```
+
+> **cgroup driver note**: rootless Docker defaults to the **systemd** cgroup driver, which expects a per-user slice (`user-<uid>.slice`) created by a logind session — something we don't have here by design. If `docker compose up --build` later fails with `open /sys/fs/cgroup/user.slice/user-<uid>.slice/cgroup.controllers: no such file or directory`, switch dockerd to manage cgroups itself instead. As `rss-svc`:
+> ```sh
+> mkdir -p ~/.config/docker
+> cat > ~/.config/docker/daemon.json << 'EOF'
+> {
+>   "exec-opts": ["native.cgroupdriver=cgroupfs"]
+> }
+> EOF
+> ```
+> then, as your sudo-capable user, `sudo systemctl restart docker-rss-svc`.
+
+**Updating rootless Docker:** the daemon and CLI live in `/home/rss-svc/bin` as a private, self-contained copy of the static binaries — entirely decoupled from the system package manager, so `apt upgrade` never touches them. To update, stop the daemon, re-run the same installer (it just re-downloads the current stable bundle for your architecture and overwrites the files in `~/bin` in place), then start it back up:
+
+```sh
+sudo systemctl stop docker-rss-svc
+sudo -u rss-svc -H curl -fsSL https://get.docker.com/rootless -o /tmp/install-rootless.sh
+sudo -u rss-svc -H sh /tmp/install-rootless.sh
+sudo systemctl start docker-rss-svc
+sudo -u rss-svc -H docker info   # confirm the new version
+```
+
+**3. Deploy the stack as `rss-svc`:**
+
+```sh
+git clone <your-repo-url> ~/rss-reader
+cd ~/rss-reader
+cp .env.example .env
+chmod 600 .env
+```
+
+Fill in `.env` with strong, unique secrets — `openssl rand -hex 32` is a convenient way to generate `JWT_SECRET`/`POSTGRES_PASSWORD`.
+
+**4. Bind published ports to localhost only.** The only thing that needs to reach this stack from outside is the reverse proxy below, and it runs on the same host. Edit `docker-compose.yml`:
+
+```yaml
+  postgres:
+    ports:
+      - "127.0.0.1:5432:5432"
+  backend:
+    ports:
+      - "127.0.0.1:8001:8001"
+  frontend:
+    ports:
+      - "127.0.0.1:8080:80"
+```
+
+**5. Bring it up:**
+
+```sh
+docker compose up --build -d
+docker builder prune -af && docker image prune -af  # reclaim disk used by old build layers/images
+```
+
+**6. Firewall** (run as your normal sudo-capable user — not `rss-svc`):
+
+```sh
+sudo ufw allow OpenSSH
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+sudo ufw enable
+```
+
+With this in place: only SSH and HTTPS are reachable from the network, the reverse proxy is the sole entry point into the app, the whole stack runs in its own user/container/network namespaces with no elevated privileges, and secrets live in a `chmod 600` `.env` owned by an account that can't do anything else on the system.
+
+### Optional: Apache reverse proxy (TLS termination)
+
+If you want to expose the app under a domain with HTTPS, put Apache in front of the `frontend` container (which keeps listening on `localhost:8080`) and let Apache handle TLS. Enable the required modules first:
+
+```sh
+sudo a2enmod proxy proxy_http proxy_wstunnel ssl headers
+```
+
+Then a vhost like this proxies everything — including the WebSocket-capable Vite/axios traffic and the `/api/` calls the frontend's nginx already forwards to the backend — to the container:
+
+```apache
+<VirtualHost *:443>
+    ServerName rss.example.com
+
+    SSLEngine on
+    SSLCertificateFile      /etc/letsencrypt/live/rss.example.com/fullchain.pem
+    SSLCertificateKeyFile   /etc/letsencrypt/live/rss.example.com/privkey.pem
+
+    ProxyPreserveHost On
+    ProxyPass        / http://127.0.0.1:8080/
+    ProxyPassReverse / http://127.0.0.1:8080/
+
+    RequestHeader set X-Forwarded-Proto "https"
+
+    ErrorLog  ${APACHE_LOG_DIR}/rss-error.log
+    CustomLog ${APACHE_LOG_DIR}/rss-access.log combined
+</VirtualHost>
+
+# Redirect plain HTTP to HTTPS
+<VirtualHost *:80>
+    ServerName rss.example.com
+    Redirect permanent / https://rss.example.com/
+</VirtualHost>
+```
+
+Notes for this setup:
+
+- Set `FRONTEND_ORIGIN=https://rss.example.com` in your root `.env` so the backend's CORS check allows the proxied origin, then `docker compose up --build -d backend`.
+- You no longer need to publish port `8080` to the LAN — change the `frontend` service's port mapping in `docker-compose.yml` to `"127.0.0.1:8080:80"` so only Apache (on the same host) can reach it.
+- Obtain the certificate with `certbot --apache -d rss.example.com` (via the [Certbot](https://certbot.eff.org/) Apache plugin), which can also write the vhost and set up auto-renewal for you.
+
+### Notes
+
+- Migrations run automatically at backend startup — no manual `diesel` step needed in production.
+- Secrets (`POSTGRES_PASSWORD`, `JWT_SECRET`, `FRONTEND_ORIGIN`) come from the root `.env`, which is gitignored and interpolated into `docker-compose.yml` via `${VAR}` — never commit real secrets.
+- If you need the app reachable from multiple origins (e.g. `localhost:8080` on desktop and `<lan-ip>:8080` on a phone), the current single-origin CORS check (`FRONTEND_ORIGIN`) won't allow both — pick the one you'll actually use, or relax the CORS policy in `src/main.rs` for a self-hosted, trusted-network setup.
