## ✨ Features

- 📅 **30+ Social Platforms** — schedule posts to X, LinkedIn, Facebook, Threads, TikTok, YouTube, Reddit, Mastodon, Discord, Slack, Pinterest, etc.
- ⚡ **One-click deploy** — duplicate the Space, add `HF_TOKEN`, you're done.
- 💾 **Persistent across restarts** — PostgreSQL + uploaded media auto-backed up to a private HF Dataset every 5 min and restored on boot.
- 💓 **Keep-Alive** — add `CLOUDFLARE_WORKERS_TOKEN` as a Space secret and a cron monitor is created automatically via Cloudflare Workers.
- 🌐 **Outbound firewall workaround** — optional Cloudflare Worker proxy auto-provisioned for blocked platform APIs.
- 🔒 **Secrets generated** — `JWT_SECRET` auto-generated on first boot and persisted, no manual setup.
- 🏠 **100% HF-Native** — no external Postgres/Redis/storage accounts needed for the default path.
- 📌 **Pinned to v2.11.3** — last release before Postiz mandated Temporal (which doesn't fit in a single HF container).

## 🚀 Quick Start

### Step 1: Duplicate this Space

[![Duplicate this Space](https://huggingface.co/datasets/huggingface/badges/resolve/main/duplicate-this-space-xl.svg)](https://huggingface.co/spaces/somratpro/HuggingPost?duplicate=true)

### Step 2: Add `HF_TOKEN`

In your new Space's **Settings → Variables and secrets → New secret**:

| Secret | How to get it |
| :--- | :--- |
| `HF_TOKEN` | [huggingface.co/settings/tokens](https://huggingface.co/settings/tokens) → New token → **Write** access |

> [!WARNING]
> Without `HF_TOKEN`, your data (accounts, scheduled posts, uploaded media) is **lost on every Space restart**. Set this up first.

### Step 3: Wait for the build (~5–8 min first time)

Watch progress in the **Logs** tab. The Postiz build is heavy because it compiles a Next.js frontend + NestJS backend.

### Step 4: Open the Space

Land on the HuggingPost dashboard. Click **Open Postiz →** to reach the login page. **Sign up** to create the first admin account — registration is auto-activated unless you set `RESEND_API_KEY`.

### Step 5: Set Up Keep-Alive (1 min)

Add your **Cloudflare Workers Token** as a Space secret named `CLOUDFLARE_WORKERS_TOKEN`. HuggingPost will automatically create a Worker cron that pings `/health` every 10 min. Without this, the Space will sleep and scheduled posts won't fire.

## 🔑 Configuration

### Required

| Variable | Purpose |
| :--- | :--- |
| `HF_TOKEN` | Write-access HF token — enables backup persistence |

### Recommended

| Variable | Default | Purpose |
| :--- | :--- | :--- |
| `SYNC_INTERVAL` | `3600` | Backup interval in seconds (1 hour) |
| `BACKUP_DATASET_NAME` | `huggingpost-backup` | Private dataset name (`<user>/<name>`) |
| `RESEND_API_KEY` | — | Required only if you want signup activation emails |

### Storage (Optional — for media offload)

By default, uploaded media (post images/videos) is stored in `/postiz/uploads` inside the container and included in the HF Dataset backup. If your media exceeds ~80 MB total, switch to Cloudflare R2:

| Variable | Purpose |
| :--- | :--- |
| `STORAGE_PROVIDER` | Set to `cloudflare` |
| `CLOUDFLARE_ACCOUNT_ID` | R2 account ID |
| `CLOUDFLARE_ACCESS_KEY` | R2 access key |
| `CLOUDFLARE_SECRET_ACCESS_KEY` | R2 secret |
| `CLOUDFLARE_BUCKETNAME` | R2 bucket name |
| `CLOUDFLARE_BUCKET_URL` | Public R2 URL prefix |

R2 free tier is 10 GB storage + 1M reads/month — plenty for typical use.

### Advanced

| Variable | Default | Purpose |
| :--- | :--- | :--- |
| `JWT_SECRET` | auto-generated | If unset, generated and persisted on first boot |
| `SYNC_MAX_FILE_BYTES` | `104857600` (100 MB) | Skip backup if tarball exceeds this size |
| `DISABLE_REGISTRATION` | `false` | Set to `true` after creating your admin account |
| `API_LIMIT` | `30` | Public API hourly rate limit |

## 💾 Backup & Persistence

Every `SYNC_INTERVAL` seconds (default 5 min), HuggingPost:

1. Runs `pg_dump` on the Postiz database.
2. Tars the dump + `/postiz/uploads` + `/postiz/.secrets`.
3. Uploads `snapshots/latest.tar.gz` to your private dataset `<your-username>/huggingpost-backup`.

On boot, the reverse happens — secrets restored first, then DB drop+recreate+replay, then uploads copied back. Your scheduled posts, accounts, and media survive restarts.

**To inspect or download your backup:**

```bash
huggingface-cli download --repo-type dataset <your-username>/huggingpost-backup
```

> [!NOTE]
> The dataset is **private** by default. Don't share its URL publicly — the SQL dump contains your full Postiz state, including encrypted social-media tokens.

## 💓 Keep It Awake

Free HF Spaces sleep after ~48h of no traffic. A sleeping Space cannot fire scheduled posts. Add your `CLOUDFLARE_WORKERS_TOKEN` as a Space secret. HuggingPost will automatically create a Cloudflare Worker cron that pings the Space every 10 minutes to keep it active. The dashboard shows the current "Keep Awake" status.

## 🌐 Cloudflare Proxy *(Optional)*

Hugging Face Spaces sometimes block outbound HTTP to specific social-platform APIs. HuggingPost ships the same transparent Cloudflare Worker proxy used in HuggingClip / HuggingClaw / Hugging8n.

**Auto-setup:**

1. Create a Cloudflare API Token with `Workers Scripts: Edit` permission.
2. Add `CLOUDFLARE_WORKERS_TOKEN` as a Space secret.
3. Restart the Space.

HuggingPost will create or update a Worker named `<your-space-host>-proxy` and route blocked outbound traffic through it transparently. You can add extra domains with `CLOUDFLARE_PROXY_DOMAINS` (comma-separated, merged with built-in defaults). Set to `*` to proxy all external traffic.

## 🔌 Connecting Social Accounts

Each social platform requires you to register your Postiz instance as an OAuth app. The callback URL pattern is:

```
https://<your-space-host>/app/api/integrations/social/<platform>/callback
```

(Note the `/app` prefix — Postiz UI is mounted there so its API is too.)

For each platform you want (X, LinkedIn, Facebook, etc.), follow the [Postiz provider docs](https://docs.postiz.com/providers) to obtain client ID + secret, then enter them inside Postiz **Settings → Channels** (NOT as Space secrets — Postiz stores them encrypted in its DB).

> [!TIP]
> Some platforms (like X) require a publicly verifiable domain. The HF Space subdomain (`*.hf.space`) works for most but not all platforms. Check each platform's app-creation requirements.

**Single-port routing** (port 7860, the only port HF Spaces exposes):

| Path | Target | Notes |
| :--- | :--- | :--- |
| `/` | HuggingPost dashboard (local) | Status + Keep Awake tile |
| `/health`, `/status` | local | JSON handlers |
| `/app` or `/app/*` | Postiz nginx `:5000` | `/app` stripped — Next.js built with `basePath="/app"` |
| `/_next/*`, `/static/*` | 301 → `/app/<path>` | Catches absolute-URL leaks |
| anything else | 404 | — |

**Internal processes:**

| Process | Port | Notes |
| :--- | :--- | :--- |
| `health-server.js` | 7860 (public) | Dashboard + reverse proxy |
| nginx | 5000 (internal) | Routes `/api`→3000, `/uploads`→fs, `/`→4200 |
| Postiz backend (NestJS) | 3000 | Started by PM2 |
| Postiz frontend (Next.js) | 4200 | Started by PM2, `basePath=/app` baked at build |
| Postiz workers | — | BullMQ consumer |
| Postiz cron | — | Schedule tick |
| `postgres` | 5432 | — |
| `redis-server` | 6379 | — |
| `postiz-sync.py` (loop) | — | — |

Total resident set ~3–6 GB under typical load — well within HF free tier's 16 GB.

## 🐛 Troubleshooting

**First boot takes 5–8 minutes**
The Next.js frontend is not compiled during the Docker build (the HF builder's ~4 GB memory limit is less than `next build` needs). Instead it compiles on first container startup where 16 GB is available. Watch `[frontend-build]` lines in the Logs tab. Postiz starts automatically when done. All subsequent restarts are fast — the compiled `.next` is stored in the HF Dataset backup and restored at boot.

**"Postiz backend unavailable" on first load**
On restarts after the first boot, wait 30–90 s for PM2 processes to come up. Check the dashboard status badges.

**Data lost after restart**
`HF_TOKEN` is not set, or it doesn't have write access. Add it and the next restart will restore from backup. The backup must have run at least once before the restart.

**Backup too large (>100 MB)**
Either move media to Cloudflare R2 (`STORAGE_PROVIDER=cloudflare`) or raise `SYNC_MAX_FILE_BYTES`. The HF Dataset itself supports much larger files, but huge backups slow restart.

**Scheduled posts didn't fire while I was away**
The Space slept. Add `CLOUDFLARE_WORKERS_TOKEN` as a Space secret to enable automatic keep-awake monitoring.

**OAuth callback fails for X/Facebook/LinkedIn**
Some platforms reject `*.hf.space` subdomains as redirect URIs. You may need to put a custom domain in front (Cloudflare → HF Space CNAME).

**Out of memory during build (exit 137 / OOMKilled)**
The Dockerfile patches `apps/frontend/next.config.js` to disable sourcemap generation (`productionBrowserSourceMaps: false` + Sentry `sourcemaps.disable: true`). Without these, peak build memory exceeds HF Space builder limits. If you forked and removed those sed patches, OOM returns. Builds also run apps sequentially (backend → workers → cron → frontend) at 3 GB heap each — parallel builds OOM.

**`prisma-db-push` fails on first boot**
Usually means Postgres didn't finish starting. Container will exit and HF will auto-restart — second boot usually succeeds. If it persists, check Logs for the actual Prisma error.
