Commerce

A headless storefront with a server-action cart.

commerce

Vercel's Next.js Commerce — the headless storefront: server components over a store API, a server-action cart, "use cache" data revalidated from Shopify webhooks — running on Cloudflare Workers + Static Assets through @opennextjs/cloudflare, with the Next.js data cache in an R2 bucket provisioned by Terraform through Orun and the tag cache and revalidation queue in Durable Objects the Worker itself exports — and packaged as an Orun baseline: one command takes a new storefront from nothing to live on stage and prod, in its own repository, under its own name, in ONE landing.

A fresh build needs no third-party key: until its owner connects a Shopify store, the storefront serves a bundled demo catalogue (six products, two collections, menus, pages) with a cookie cart, and checkout answers with a "connect a payment provider" notice rather than an error. See specs/epics/commerce for the design, the milestones and the as-built status.

Instantiating a product

git clone --depth 1 --branch <baseline-tag> https://github.com/sourceplane/commerce
cd commerce
orun new --blueprint repo-blueprint.yaml --out ~/sites/acme-shop --run-hooks --resume \
  --set reponame=acme-shop --set productname="Acme Shop" \
  --set githuborg=acme-inc --set subdomain=<workers-dev-subdomain>

Or, once the platform's registry lists it, from the Orun console (Baselines → commerce → Build). Two phases: 01-product creates the repository and lands the whole product as ONE pull request — intent, CI, tooling, the R2 root, the storefront and its tests — and one convergence applies the R2 bucket on stage and prod and then deploys the storefront bound to it; 02-docs records the live deployment from probed facts. BOOTSTRAP.md is the operator guide; docs/phases/ has a page per phase.

The new repository receives the product only — the app, its R2 root, its tests, its CI, its tooling, a README of its own and its operating contract — renamed throughout to the product's name, repository, Cloudflare Worker and bucket names. None of this repository's machinery ships. Its owner then connects Shopify with three Worker secrets (the product's README, "Connecting Shopify"); the card asks for no Shopify key, because the platform does not broker one.

Getting started

pnpm install
pnpm run wire:fixture   # render apps/web/wrangler.jsonc from the offline fixture
pnpm typecheck
pnpm lint
pnpm test
pnpm build              # next build + opennextjs-cloudflare build → apps/web/.open-next
pnpm --filter @app/web dev        # http://localhost:3000, Next's dev server
pnpm --filter @app/web preview    # wrangler dev over the built Worker, a local R2 bucket and local Durable Objects

Without Shopify facts in the environment both serve the demo catalogue. To run against a store, put its facts in apps/web/.env.local for Next's dev server and in apps/web/.dev.vars for the Worker preview (both from apps/web/.env.example).

How it maps to Vercel

VercelHere
Next.js hosting (SSR, server actions, route handlers, next/og)One Cloudflare Worker (.open-next/worker.js) + Static Assets (ASSETS)
Data Cache: "use cache" entries with cacheLife("days")The R2 bucket bound as NEXT_INC_CACHE_R2_BUCKET, written at request time
Tag revalidation: revalidateTag from the Shopify webhook, updateTag from cart actionsA sharded Durable Object tag cache (NEXT_TAG_CACHE_DO_SHARDED) consulted on every cache read
Stale-while-revalidate (ISR)A Durable Object queue (NEXT_CACHE_DO_QUEUE) that re-renders stale routes through the Worker's WORKER_SELF_REFERENCE binding
next/image over cdn.shopify.comThe Worker's own /_next/image, validated against remotePatterns, served unoptimised; the demo's SVGs are static assets
The Shopify integration's env varsSHOPIFY_STORE_DOMAIN, SHOPIFY_STOREFRONT_ACCESS_TOKEN, SHOPIFY_REVALIDATION_SECRET as Worker secrets — and, unset, the bundled demo catalogue instead of an empty store
VERCEL_PROJECT_PRODUCTION_URLNothing: metadata, robots and the sitemap are built on the request's origin (app/site.ts)
Deploy on pushOrun applies the bucket and deploys <repo>-web-{stage,prod} on merge to main (apps/web/component.yaml)
"Deploy with Vercel" (clone the template)orun new --blueprint repo-blueprint.yaml — a new repository, branded, deployed

Partial prerendering is off: @opennextjs/cloudflare 1.20 cannot run Next 16's Cache Components on workerd yet, so the storefront keeps upstream's "use cache" directives through experimental.useCache and renders every route at request time.

How the bucket reaches the Worker

infra/terraform/cloudflare-r2 ──apply (r2-data token)──► orun secret WIRING_CLOUDFLARE_R2 (stage, prod)
                                               │   (each deploy resolves it as it starts;
                                               │    a missing one fails the lane)
                                               ▼
apps/web  dependsOn cloudflare-r2 (enforced on main) · secretEnv WIRING_CLOUDFLARE_R2_<ENV>
  build:  tooling/wire/live.mjs → wrangler.jsonc with the environment's bucket name
          (dev, verify-only, renders the fixture) → next build → opennextjs-cloudflare
  deploy: workers-deploy token → <repo>-web-<env>, its Durable Objects migrated on first deploy

wrangler.jsonc is committed as the fixture render of wrangler.template.jsonc, because the deploy lane's verify-app-structure step checks the config exists before it builds; testing/e2e.test.sh fails if the two disagree.

CI

WorkflowWhat it runsShips to a product
ci.ymlthe Orun pipeline, and the only workflow a product carries: orun plan --changed, then one job per lane. A pull request runs the verify lanes (the R2 root planned for stage and prod, the storefront built and dry-deployed per environment; they neither lint nor run the tests, which baseline.yml's e2e tier runs before every tag), except the bootstrap's own landings (orun/BASE-*), where plan alone runs and nothing waits for it (the landing checked its commit in the box); a merge applies the R2 bucket, then deploys stage → prod. It plans nothing while intent.yaml names the placeholder workspace ws_CHANGE_ME, as this repository does. A manual run (Orunbase's Deploy button, or Run workflow on main) plans the environment and components it names under the push-to-main trigger, so they deploy as a merge deploys themyes
