# Craft2Prints — Handoff Brief
This project was built in a series of conversations with Claude (chat interface,
zip-file delivery). The person is moving to **Claude Code** to work on it directly.
This doc summarizes where things stand so nothing gets lost in the switch.
## What this is
An e-commerce site with two parallel catalogs:
- **Personalised** (`/made-to-order`) — customers design their own version of a
product using an in-browser design tool (drag text/images onto the product).
- **Products** (`/products`) — same underlying products, but a plain "pick a
color/size, buy as-is" page, no design tool.
A single product can be flagged to appear on either catalog, or both, via
`showOnPersonalised` / `showOnProducts` booleans — same photos either way, nothing
duplicated.
Business context: UK-based, GBP is the base/canonical currency, sources some
products from a supplier called Firelabel.
## Tech stack
- Next.js 14 (App Router), TypeScript, Tailwind CSS
- Prisma + SQLite (`prisma/dev.db`) — easy to swap to Postgres later by changing
`provider` in `prisma/schema.prisma` and `DATABASE_URL`
- Zustand for cart state, persisted to **IndexedDB** (not localStorage — see
Gotchas below for why)
- Konva / react-konva for the design tool canvas
- Stripe for checkout
- Nodemailer for design-approval emails (optional, SMTP-based)
## Person's environment (important context)
- **Windows**, project lives at `D:\Craft2Prints`
- Dev server has repeatedly ended up on **port 3001** instead of 3000 because a
stale `node.exe` process keeps holding port 3000 / locking Prisma's engine
binary. Recurring fix: Task Manager → kill all `node.exe` → re-run
`npx prisma generate`. If that keeps happening, it may be worth just settling on
3001 as the working port rather than fighting it every time.
- Was previously working **inside OneDrive**, which caused `.next` build errors
(`EINVAL: invalid argument, readlink`) — project was moved out of OneDrive to fix
this. If it ever moves again, keep it outside any cloud-sync folder.
- Has hit `Watchpack Error` noise on Windows a few times — `next.config.mjs` is
already configured to fall back to polling-based file watching, which resolved it.
- Not deeply technical with the terminal — needs exact copy-pasteable commands, not
assumed familiarity with npm/Prisma/Stripe CLI workflows.
## What's built and working
- Full product management: add/edit/delete, admin-managed categories (each
scopable to either catalog), admin-managed sizes, colors as swatches (not hex
text), real photo upload with a drag-to-mark print-area box, optional back
photo (own print area), photo-per-color (front AND back), and an optional
black/white photo "tint" recolor mode as a fallback when there's no per-color
photo.
- The design tool: front/back personalization, drag/resize/rotate text and
uploaded images, 11 font choices, color swatches, size picker. Exports two
images per side: a clean transparent print-ready PNG, and a "placement
reference" image (design composited onto the actual product photo, for print
placement — only generated for photo-based products, not illustration-only
ones).
- Cart (`/cart`), real Stripe Checkout, webhook-confirmed order persistence,
admin order management (`/admin/orders`) with print files downloadable per
order, and order archiving (manual button + auto-archive after 30 days).
- Custom design-approval flow for one-off jobs: admin uploads a finished design
for a specific customer (`/admin/proofs/new`), customer reviews/approves via a
link, with an in-page chat thread and optional email notification.
- Currency selector (GBP/USD/EUR) — display only, fixed approximate rates, not
live; actual checkout always charges in GBP regardless of what's displayed.
- Dark mode, admin area behind HTTP Basic Auth (`ADMIN_USER`/`ADMIN_PASSWORD` in
`.env`).
## Known gaps / explicitly not built yet
- **Order confirmation emails** — customer only sees the on-screen success page;
no automated email receipt yet.
- **"Buy it now"** — everything currently goes through the cart, no skip-to-checkout
for a single item.
- **`/products` catalog** has no illustration fallback for placement references —
only real uploaded photos get a placement-reference image.
- Checkout's `shipping_address_collection` allowed countries is a short hardcoded
list in `src/app/api/checkout/route.ts` — worth revisiting for the actual
shipping footprint.
- No multi-currency *charging* — only display formatting. Stripe currently always
charges GBP.
## Gotchas specific to this codebase
- **Environment/session resets happened at least once during the build** — a chunk
of work (categories, sizes, product editing) briefly vanished from the working
copy and had to be reconstructed from conversation history. It was fully
recovered, but if anything ever seems to have "reverted" unexpectedly, grep for
the feature in question before assuming it was never built — it may just need
re-syncing rather than rebuilding from scratch.
- **`prisma/seed.ts` is idempotent and safe to re-run** — it only touches the 6
starter products (matched by slug) and 3 starter categories, never anything
added through the admin panel. Useful for resetting demo data without wiping
real work.
- **Cart storage**: moved from `localStorage` to IndexedDB after a real
`QuotaExceededError` crash — each cart item can carry up to 4 full-size images
(print files + placement refs), which blew past localStorage's ~5-10MB cap with
just 2-3 items. Don't move this back to localStorage.
- **The image-node-ready race condition**: uploaded images in the design tool load
asynchronously, unlike text. There's a `nodeReadyTick` mechanism in
`DesignCanvas.tsx` specifically to re-sync the resize-handle Transformer once an
image's Konva node actually mounts. If resize handles ever stop appearing on
images again, this is the first place to check — and watch out for calling a
state setter unconditionally inside an inline Konva `ref` callback, since that
callback re-fires on every render (this caused an infinite-loop bug once
already; the fix was guarding on whether the node reference actually changed).
## Setup (for a fresh Claude Code session to verify environment)
```bash
npm install
cp .env.example .env # fill in Stripe keys, admin password, etc. — see README
npx prisma generate
npm run db:push
npm run db:seed
npm run dev
```
Full details, including Stripe test-mode setup with the Stripe CLI, are in
`README.md` at the project root — it's been kept up to date throughout the build
and is the more detailed reference; treat this file as the high-level orientation
and README.md as the how-to.
