# gerbeur
|
|
|
|
A small invite-only social platform for sharing links and files. Users can post URLs and media (YouTube, SoundCloud, Bandcamp, images, audio, video, …), vote, comment, follow each other, build playlists, and search content. A real-time WebSocket layer handles live presence, vote counts, and notifications. The UI is localized (English and French) and ships multiple visual themes.

|
|
| Layer | Technology |
|
|
| -------- | ------------------------------------------------- |
|
|
| Runtime | [Deno](https://deno.com) 2.x |
|
|
| API | [Oak](https://jsr.io/@oak/oak) (HTTP + WebSocket) |
|
|
| Database | SQLite via `node:sqlite` |
|
|
| Frontend | React 19 + Vite 8 |

|
## Development
|
|
|
|
### Prerequisites
|
|
|
|
- Deno 2.x
|
|
|
|
### Setup
|
|
|
|
```sh
|
|
cp .env.example .env
|
|
# Edit .env: set GERBEUR_JWT_SECRET to the output of: openssl rand -hex 32
|
|
```
|
|
|
|
### Run
|
|
|
|
```sh
|
|
deno task dev
|
|
```
|
|
|
|
This starts both the API server (port 8000, with file watching) and the Vite dev server (port 3000) concurrently.
|
|
|
|
Open [http://localhost:3000](http://localhost:3000). On first run a default `admin` / `admin` account is created — change the password immediately.
|
|
|
|
### Environment variables
|
|
|
|
See [`.env.example`](.env.example) for the full list with descriptions. Key variables:
|
|
|
|
| Variable | Description | Default |
|
|
| ---------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------- |
|
|
| `GERBEUR_JWT_SECRET` | JWT signing secret — **required**, generate with `openssl rand -hex 32` | — |
|
|
| `GERBEUR_PUBLIC_URL` | Public-facing URL of the server (no trailing slash) — used for CORS, WebSocket origin, email links, OG URLs | `http://localhost:GERBEUR_PORT` |
|
|
| `GERBEUR_PORT` | Internal port Oak listens on | `8000` |
|
|
| `GERBEUR_LISTEN_HOST` | Network interface Oak binds to; use `127.0.0.1` to restrict to loopback | `0.0.0.0` |
|
|
| `GERBEUR_FRONTEND_URL` | Frontend base URL for email links and CORS; auto-added to allowed origins — the only variable needed when the frontend runs on a separate host | `GERBEUR_PUBLIC_URL` |
|
|
| `GERBEUR_ALLOWED_ORIGINS` | Comma-separated extra origins for CORS/WebSocket; `PUBLIC_URL` and `FRONTEND_URL` are always included — typically only needed in dev for the Vite server | `""` (empty) |
|
|
| `GERBEUR_SITE_NAME` | Site name used in the browser tab, app header, OG meta tags, and emails | `gerbeur` |
|
|
| `GERBEUR_SMTPS_URL` | SMTPS connection URL for outgoing email (`smtps://user:pass@host:465`) | unset |
|
|
| `GERBEUR_FROM_EMAIL` | Sender address for outgoing emails — required when `GERBEUR_SMTPS_URL` is set | unset |
|
|
| `GERBEUR_WELCOME_EMAIL_BODY` | Markdown body for the account-creation welcome email; supports `{{username}}` and `{{site_name}}` | built-in template |
|
|
| `VITE_API_PROTOCOL` | API protocol baked into the frontend bundle (see [Production](#production)) | `http` |
|
|
| `VITE_API_HOSTNAME` | API hostname baked into the frontend bundle | `localhost` |
|
|
| `VITE_API_PORT` | API port baked into the frontend bundle | `8000` |
|
|
|
|
## Production
|
|
|
|
### Docker (recommended)
|
|
|
|
The standard deployment runs API and frontend in a single container. The API server (Oak) serves the compiled frontend as static files, so both share the same origin — no `VITE_API_*` build args needed. Set `GERBEUR_PUBLIC_URL` to the externally-visible URL; it is automatically allowed for HTTP/WebSocket requests.
|
|
|
|
```sh
|
|
docker build -t gerbeur .
|
|
|
|
docker build -t gerbeur .
|
|
|
|
docker run -d \
|
|
-p 8000:8000 \
|
|
-v gerbeur-db:/app/api/sql \
|
|
-v gerbeur-uploads:/app/api/uploads \
|
|
-e GERBEUR_JWT_SECRET=$(openssl rand -hex 32) \
|
|
-e GERBEUR_PUBLIC_URL=https://example.com \
|
|
-e GERBEUR_SITE_NAME=mysite \
|
|
--name gerbeur \
|
|
gerbeur
|
|
```
|
|
|
|
The two volumes are required for persistence:
|
|
- `gerbeur-db` — SQLite database (`api/sql/gerbeur.db`), initialized automatically on first run
|
|
- `gerbeur-uploads` — user-uploaded files (`api/uploads/`)
|
|
|
|
#### Separate API and frontend (optional)
|
|
|
|
If you need to run the API on a different host than the frontend, pass the API location as build args so it gets baked into the frontend bundle. In that setup, add the frontend origin to `GERBEUR_ALLOWED_ORIGINS` so cross-origin HTTP/WebSocket requests are accepted:
|
|
|
|
```sh
|
|
docker build \
|
|
--build-arg VITE_API_PROTOCOL=https \
|
|
--build-arg VITE_API_HOSTNAME=api.example.com \
|
|
--build-arg VITE_API_PORT=443 \
|
|
-t gerbeur .
|
|
```
|
|
|
|
### Reverse proxy
|
|
|
|
Put a reverse proxy (nginx, Caddy, …) in front of the container to handle TLS. Forward everything to port 8000. Example Caddyfile:
|
|
|
|
```
|
|
example.com {
|
|
reverse_proxy localhost:8000
|
|
}
|
|
```
|
|
|
|

Each of `components/`, `contexts/`, `hooks/` and `utils/` is split into the
|
|
same domain folders — `auth`, `category`, `chat`, `comment`, `dump`, `editor`,
|
|
`feed`, `form`, `layout`, `player`, `playlist`, `profile`, `social`, `theme`,
|
|
`ws` — plus `shared/` for what belongs to no single domain. So the chat lives in
|
|
`components/chat/`, `contexts/chat/`, `hooks/chat/` and `utils/chat/`, and its
|
|
tests in `test/<same path>`. Files are imported directly (no `index.ts`
|
|
barrels), and everything uses named exports.
