# Klonkt

Your own, **self-hosted** corner of the web — for your story, your visuals and
your sound. Built on **Node + SQLite + htmx**: lightweight, server-rendered, and
yours. No algorithm, no ads, no platform sitting in between.

## What it does

- **Solo or hub** — one personal site, or a label/collective with multiple
  makers under one roof.
- **Blog & photos** — posts with cover, tags, timeline or grid.
- **Host your own music** — built-in audio player with tracks, albums and playlists.
- **Fans & comments** — visitors sign in with Google (optional) and comment.
- **Grow**: newsletter, download-for-email, EPK/press kit, link-in-bio,
  show calendar, and **cookie-free statistics**.
- **Circles** — connect your site with other Klonkt sites and show each other's
  public posts; decentralized, with no central platform (Ed25519-signed federation).
- **Themes & languages** — multiple palettes (light + dark), interface in EN/NL/DE.
- **Installable (PWA)**, **privacy-first** (self-hosted fonts, no tracking).

### Lite mode (no audio)

Set `KLONKT_AUDIO=off` in `.env` to disable the entire audio/music feature.
Klonkt then runs as a lightweight **blog/photo/EPK/links site without ffmpeg** —
ideal for minimal hosting. Hub, Circles and external embeds
(YouTube/SoundCloud/Spotify) keep working.

## Self-hosting

Klonkt is a **Node app** — run it on a **VPS, in Docker, or on a Node hosting
platform (PaaS)**. **Not** on classic shared PHP hosting. The database (SQLite)
creates itself on first start.

### Option A — Docker (recommended)

Node, ffmpeg and cwebp are inside the image; you only need Docker.

```bash
git clone https://github.com/roboburr/klonkt.git && cd klonkt
cp .env.example .env          # set SESSION_SECRET + PUBLIC_BASE_URL
docker compose up -d
```

Data (database + media) stays in the `klonkt-data` volume, even across updates.
Updating: `git pull && docker compose up -d --build`.

### Option B — VPS installer (Debian/Ubuntu)

One command: installs Node 20, Caddy (automatic HTTPS) and a systemd service.
Coexistence-safe (won't touch an existing Node/web server).

```bash
curl -fsSL https://raw.githubusercontent.com/roboburr/klonkt/main/scripts/install.sh \
  | sudo bash -s -- --domain yourdomain.com
```

After that you can update with `klonkt-update`.

### Option C — bare Node (20+)

```bash
git clone https://github.com/roboburr/klonkt.git && cd klonkt
npm ci
cp .env.example .env          # set SESSION_SECRET + PUBLIC_BASE_URL
npm start                     # the database is created on first start
```

For production, put it behind a process manager (pm2/systemd) and a
reverse proxy. `cwebp` is optional (`apt install webp`) for WebP images.

### HTTPS (Docker / bare Node)

Put a reverse proxy in front of the app. With **Caddy** (automatic Let's Encrypt):

```caddy
yourdomain.com {
    reverse_proxy localhost:3000
    encode gzip zstd
}
```

(The VPS installer sets up Caddy + HTTPS for you already.)

### First run

Open your site → you get the **setup wizard**: pick your language, name your site
and create your admin. The **first user automatically becomes the administrator**;
registration then closes. Lost your password?
`npm run reset-admin` (Docker: `docker compose exec klonkt npm run reset-admin`).

## Configuration (`.env`)

| Variable | Required | What |
|---|---|---|
| `SESSION_SECRET` | ✅ | Random string of ≥32 characters |
| `PUBLIC_BASE_URL` | ✅ | Canonical URL (e.g. `https://yourdomain.com`) |
| `GOOGLE_CLIENT_ID` / `_SECRET` / `_REDIRECT_URI` | — | Google login for listeners (your own OAuth client; never grants admin) |
| `SMTP_HOST` / `_PORT` / `_USER` / `_PASS` / `_FROM` | — | Email for password reset + newsletter |
| `KLONKT_DEFAULT_LANG` | — | Default language for visitors (`en`/`nl`/`de`) |
| `KLONKT_AUDIO` | — | `off` = lite mode (no audio/ffmpeg) |
