Setup

With DDE (recommended)

Prerequisites: DDE.

# 1. Clone the repository
git clone https://github.com/sbaerlocher/parqet.beer.git
cd parqet.beer

# 2. Copy and fill in environment variables
cp .dev.vars.example .dev.vars
# Set PARQET_CLIENT_ID and SESSION_SECRET

# 3. Start the project (installs dependencies automatically)
dde project:up

Then open https://parqet-beer.test in your browser.

Without DDE

Prerequisites: Node.js (see .nvmrc), pnpm.

# 1. Clone the repository
git clone https://github.com/sbaerlocher/parqet.beer.git
cd parqet.beer

# 2. Install dependencies
pnpm install

# 3. Copy and fill in environment variables
cp .dev.vars.example .dev.vars
# Set PARQET_CLIENT_ID and SESSION_SECRET

# 4. Start the dev server
pnpm dev

Then open http://localhost:5173 in your browser.

Environment Variables

Parqet Connect runs as a public client with PKCE — no client secret required.

In production, secrets are set via the Cloudflare dashboard, not through wrangler.jsonc.

Scripts

With DDE, prefix commands with dde exec:

dde exec pnpm build            # Build for Cloudflare Pages
dde exec pnpm check            # TypeScript + Svelte check
dde exec pnpm test             # Vitest (unit tests)
dde exec pnpm lint             # Prettier check
dde exec pnpm format           # Prettier write

Without DDE:

pnpm dev              # Vite dev server (localhost:5173)
pnpm build            # Build for Cloudflare Pages
pnpm preview          # Local Cloudflare Pages preview via wrangler
pnpm check            # TypeScript + Svelte check
pnpm test             # Vitest (unit tests)
pnpm lint             # Prettier check
pnpm format           # Prettier write
pnpm generate:assets  # SVG → PNG (favicon, OG image) re-render

Deployment (Cloudflare Pages)

Fork note: wrangler.jsonc contains only placeholder IDs. Before you can deploy, you need to create your own Cloudflare resources (KV namespace, Secrets Store) and fill in the IDs. The setup script automates this flow.

Automated setup (recommended)

./scripts/setup-fork.sh

The script creates KV namespaces (preview + production), a Secrets Store, and a session secret, then patches wrangler.jsonc with the generated IDs.

Manual flow

For a step-by-step approach, see the individual commands in scripts/setup-fork.sh or scripts/README.md.

Then replace the Parqet Client ID in wrangler.jsonc under vars.PARQET_CLIENT_ID with your own OAuth app ID from the Parqet Developer Portal. The redirect URI configured in your Parqet app must match your deploy domain.

Deploy via Git integration (push to main) or manually:

pnpm build
pnpm exec wrangler pages deploy .svelte-kit/cloudflare
