Netlify Deployment

ZPan runs on Netlify via Netlify Functions v2 (Node, ESM). The React SPA is served from Netlify's CDN. All API requests are handled by a single Netlify Function that connects to a Turso (libSQL) database.

Cost: Free tier covers 125,000 function invocations per month, 100 GB bandwidth, and unlimited static hosting. Turso's free tier covers 9 GB storage, 1 B row reads, and 25 M row writes per month — enough for personal use at $0/month.

Prerequisites

1. Fork the repo — go to github.com/saltbo/zpan and click Fork.

2. Create a Turso database — takes about 3 minutes:

   curl -sSfL https://get.tur.so/install.sh | bash
   turso auth signup          # GitHub OAuth, no credit card
   turso db create zpan
   turso db show zpan --url   # → TURSO_DATABASE_URL value
   turso db tokens create zpan  # → TURSO_AUTH_TOKEN value
   

   Alternatively, use the Turso dashboard — no CLI needed.

3. Create a Netlify site — one-time setup, done in your browser:

   • Go to app.netlify.com → Add new site → Deploy manually.
   • Note your Site ID from Site configuration → General.

   Or via CLI:

   pnpm add --global netlify-cli
   netlify login
   netlify sites:create --name my-zpan
   

4. Get a Netlify personal access token — go to app.netlify.com/user/applications → Personal access tokens → New access token.

---

Add GitHub Secrets

In your fork, go to Settings → Secrets and variables → Actions → New repository secret and add:

Secret	Value
TURSO_DATABASE_URL	libsql://your-db-name-orgname.turso.io
TURSO_AUTH_TOKEN	Turso auth token from step 2
NETLIFY_AUTH_TOKEN	Netlify personal access token from step 4
NETLIFY_SITE_ID	Site ID from your Netlify site settings
BETTER_AUTH_SECRET	(optional) — auto-generated on first deploy if omitted

S3 bucket credentials are not GitHub Secrets. After deploy, you configure storage backends via the ZPan admin UI (Admin → Storages). This keeps bucket credentials out of CI logs and lets one ZPan instance manage multiple buckets.

---

Trigger Deploy

Push to main or go to Actions → Deploy to Netlify → Run workflow.

The workflow will:

1. Resolve the latest ZPan release from the upstream repo
2. Apply Turso migrations (drizzle-kit migrate)
3. Build the React SPA and the Netlify Function
4. Deploy to your Netlify site
5. Auto-generate BETTER_AUTH_SECRET (first deploy only)
6. Write the live URL to the workflow run summary

Subsequent pushes redeploy without re-creating resources.

---

First-Boot Storage Setup

After the workflow reports success:

1. Open the deployed URL (shown in the workflow summary)
2. Sign up — the first account becomes the admin
3. Go to Admin → Storages → Add storage
4. Fill in your S3-compatible bucket details (endpoint, region, access key, secret)
5. Save — ZPan verifies the bucket is reachable and marks it active

This is identical to the setup flow for Cloudflare Workers and Docker deployments.

Configuration & Cost

Environment variables

Set additional env vars via the Netlify dashboard (Site configuration → Environment variables) or CLI:

netlify env:set BETTER_AUTH_URL https://zpan.example.com --context production
netlify env:set TRUSTED_ORIGINS https://zpan.example.com --context production

Variable	Required	Notes
TURSO_DATABASE_URL	Yes	Set as a GitHub Secret; workflow passes it at build time
TURSO_AUTH_TOKEN	Yes	Set as a GitHub Secret
BETTER_AUTH_SECRET	Yes	Auto-generated on first deploy
BETTER_AUTH_URL	Recommended	Set to your production URL (default: inferred from request origin)
TRUSTED_ORIGINS	Recommended	Comma-separated allowed origins for auth cookies

Custom domain

In the Netlify dashboard → Domain management → Add a domain. No changes to the workflow required.

Running migrations manually

TURSO_DATABASE_URL=libsql://your-db.turso.io \
TURSO_AUTH_TOKEN=your-token \
pnpm db:migrate

Free-tier limits

Resource	Free limit
Netlify Functions	125,000 invocations/month
Netlify Bandwidth	100 GB/month
Turso Storage	9 GB
Turso Row reads	1 B/month
Turso Row writes	25 M/month

Upgrade to Netlify Pro ($19/month) or Turso Scaler ($29/month) when you need more.

Entitlement Refresh (License Cert)

ZPan refreshes its entitlement certificate every 6 hours. On Netlify there is no persistent process, so you need to trigger a refresh via an external scheduler.

Setup

1. Generate a secret:

   openssl rand -hex 32
   

2. Add the env var via the Netlify dashboard (Site configuration → Environment variables) or CLI:

   netlify env:set REFRESH_CRON_SECRET <your-secret> --context production
   

3. Schedule the calls using Netlify Scheduled Functions or an external cron service (e.g. cron-job.org):

   POST https://your-site.netlify.app/api/licensing/refresh-cron?secret=<REFRESH_CRON_SECRET>
   

   Run this every 6 hours.

   POST https://your-site.netlify.app/api/licensing/traffic-sync-runs?secret=<REFRESH_CRON_SECRET>
   

   Run this every 10 minutes.

If REFRESH_CRON_SECRET is not set, the endpoint returns 401 for all requests.
