Shop Storefront

MONO — a minimal editorial product storefront, and a real, buildable app you fork on hanzo.app and deploy live on Hanzo Cloud. Monochrome chic: big product imagery, one palette, three views.

• UI — @hanzo/gui (the Hanzo design system) under Vite + React 19. Product imagery is generated from the design system itself — a paper ground, one ink mark, and an editorial index — so an image-less catalogue still looks art-directed.
• Auth — @hanzo/iam, OAuth2 PKCE against hanzo.id. No local passwords — IAM owns every credential interaction.
• Data — @hanzo/base, the IAM-native, org-scoped data plane. Products and the cart are real Base collections.

The shop

Three views over two collections:

• Storefront grid — the catalogue. A fresh org is empty and seeds the demo collection into Base with one press.
• Product detail — the studio image, an editorial spec, a stock-bounded quantity stepper, and add-to-cart.
• Cart — line items, an order summary, and a checkout stub that clears the cart. Wire it to Hanzo Commerce to take real orders.

Browse the catalogue signed-out; sign in to build a cart that persists per-org.

Run it

npm install
npm run dev        # http://localhost:5173
npm run build      # tsc --noEmit && vite build  ->  dist/
npm run preview    # serve the production build (SPA fallback on)

Out of the box it runs against live Hanzo (hanzo.id + api.hanzo.ai) — no config needed to see the storefront and sign-in flow. Copy .env.example to .env to point at a different environment.

Environment contract

Only VITE_-prefixed vars reach the browser (this is a static SPA — there is no server). Defaults in parentheses.

Var	Purpose
VITE_HANZO_IAM_URL (https://hanzo.id)	OIDC issuer.
VITE_HANZO_CLIENT_ID (hanzo-app)	IAM application (<org>-<app>). Its redirect-URI list must allow this deploy's /auth/callback — see Ambient IAM.
VITE_HANZO_REDIRECT_URI (${origin}/auth/callback)	PKCE redirect.
VITE_HANZO_BASE_URL (https://api.hanzo.ai)	Browser-reachable Hanzo Base data plane. Deploy injects the provisioned URL.

How auth works — ambient IAM

login() starts an OAuth2 PKCE S256 redirect to hanzo.id; hanzo.id returns to /auth/callback, where handleCallback() exchanges the code for tokens (stored in localStorage, refresh-aware via offline_access). Every deployed app is a static site at <slug>.hanzo.app; there is no server token — the SPA authenticates the user in the browser and carries the resulting IAM JWT to Base. The one deploy requirement: the IAM client (VITE_HANZO_CLIENT_ID) must list this origin's /auth/callback as an allowed redirect URI.

How data works — Base from schema.sql

schema.sql is the app's databaseSchema (SQL DDL): a products collection and a cart_items collection. On publish, Hanzo Cloud translates each CREATE TABLE into a Hanzo Base collection (provisionBaseFromDDL, additive + idempotent). Base manages id/created/updated/owner/org, stamps owner+org from the verified IAM principal, and scopes every row to the caller's org (@request.auth.org_id = org). At runtime the views read/write those collections through @hanzo/base/react (useQuery/useMutation) carrying the IAM token. Keep schema.sql in lockstep with src/lib/shop.ts.

Deploy — Hanzo Cloud

hanzo.yml declares a static build (npm run build → dist/, served at <slug>.hanzo.app) plus the Base schema to provision and the env to inject. Do not build a container image locally — Hanzo Cloud owns builds and deploys. CI here only proves the template compiles green.
