- Undo Vessel→Cost Centre rename in admin (admin shows "Vessel Management" again) - Sidebar: "Cost Centres"→"Vessels", "Accounts"→"Accounting Codes" - PO forms (new/edit/import/manager-edit) now show both Vessels (with code) and Sites in the Cost Centre dropdown, encoded as v:<id> / s:<id> via a costCentreRef field - vesselId on PurchaseOrder is now nullable; siteId is set when a site is the cost centre - History, approvals, dashboard, my-orders, payments display vessel.name ?? site.name as Cost Centre - History and approvals cost centre filters use costCentreRef URL param supporting both types - Admin vessel form: adds Site assignment dropdown - Admin accounts: renamed to "Accounting Code" throughout (pages, forms, sidebar) - PO detail and exports: "Account" label renamed to "Accounting Code" - Site detail: "Assigned Vessels (Cost Centres)" heading; vessel detail breadcrumb fixed - Create PO links from vessel/site detail use ?costCentreRef= param - Export routes handle costCentreRef filter param (with legacy vesselId fallback) - DB migration: ALTER TABLE PurchaseOrder ALTER COLUMN vesselId DROP NOT NULL - CLAUDE.md updated with Cost Centre Model documentation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||
|
||
## Commands
|
||
|
||
```bash
|
||
# Development
|
||
pnpm dev # Next.js + Turbopack at localhost:3000
|
||
pnpm lint # ESLint
|
||
pnpm type-check # tsc --noEmit
|
||
|
||
# Tests
|
||
pnpm test # Unit tests (Vitest, jsdom)
|
||
pnpm test:watch # Unit tests in watch mode
|
||
pnpm test:integration # Integration tests (Vitest, node + real DB)
|
||
pnpm test:e2e # E2E tests (Playwright, headless)
|
||
pnpm test:e2e:ui # E2E tests with interactive UI
|
||
pnpm test:all # All test suites
|
||
|
||
# Run a single test file
|
||
pnpm test -- tests/unit/po-line-items-editor.test.tsx
|
||
pnpm test:integration -- tests/integration/create-po.test.ts
|
||
|
||
# Database
|
||
pnpm db:migrate # Create + apply migration (dev)
|
||
pnpm db:migrate:deploy # Apply migrations (CI/prod)
|
||
pnpm db:seed # Populate sample data
|
||
pnpm db:studio # Prisma GUI at localhost:5555

## Architecture
|
||
|
||
### Overview
|
||
|
||
Internal purchase order management system for a maritime company. Full-stack Next.js 15 App Router app with Prisma + PostgreSQL, NextAuth v5 credentials auth, and Tailwind CSS v4.
|
||
|
||
**Key design decisions:**
|
||
- Server Components for all data-fetching pages; Client Components only where interactivity is needed
|
||
- Server Actions for all mutations (form submissions, approvals, etc.)
|
||
- Prisma `Decimal` fields **cannot** be passed directly to Client Components — convert with `Number()` in the Server Component before passing as props (see `po-detail.tsx` → `lineItemsForEditor` pattern)
|
||
- File storage toggles automatically: Cloudflare R2 in production, `.dev-uploads/` directory in development
|
||
- Email toggles automatically: Resend in production, console log in development
|
||
|
||
### PO Lifecycle (State Machine)
|
||
|
||
`lib/po-state-machine.ts` enforces all status transitions. The canonical flow:
|
||
|
||
```
|
||
DRAFT → SUBMITTED → MGR_REVIEW → MGR_APPROVED → SENT_FOR_PAYMENT → PAID_DELIVERED → CLOSED
|
||
↓↑
|
||
EDITS_REQUESTED / REJECTED / VENDOR_ID_PENDING
|
||
```
|
||
|
||
Every status change is validated against the state machine and recorded as a `POAction` row (audit trail).
|
||
|
||
### Role-Based Permissions
|
||
|
||
`lib/permissions.ts` defines `hasPermission(role, permission)` and `requirePermission(role, permission)`. Roles: `TECHNICAL`, `MANNING`, `ACCOUNTS`, `MANAGER`, `SUPERUSER`, `AUDITOR`, `ADMIN`.
|
||
|
||
**Pattern:** Server Actions call `requirePermission()` at the top before any DB write.
|
||
|
||
### Key Directories
|
||
|
||
- `app/(portal)/` — All authenticated pages (portal layout with sidebar)
|
||
- `app/api/po/[id]/export/` — PDF and XLSX export endpoint
|
||
- `lib/validations/po.ts` — Zod schemas for PO forms; exports `TC_FIXED_LINE` and `TC_DEFAULTS`
|
||
- `lib/po-state-machine.ts` — All valid status transitions with required roles
|
||
- `lib/notifier.ts` — Email dispatch (Resend in prod, console in dev)
|
||
- `lib/storage.ts` — File upload/download (R2 in prod, local in dev)
|
||
- `components/po/` — PO-specific components (line items editor, status badge, etc.)
|
||
- `tests/integration/helpers.ts` — `makeSession()`, `makePoForm()`, `fd()` for integration test setup
|
||
|
||
### Cost Centre Model
|
||
|
||
A PO's "cost centre" is either a **Vessel** or a **Site**. `PurchaseOrder` has both `vesselId String?` (nullable) and `siteId String?` — exactly one is set.
|
||
|
||
**Form encoding:** All PO creation/edit forms use a `costCentreRef` field with values `v:<vesselId>` (vessel) or `s:<siteId>` (site). Server actions parse this to set the correct FK.
|
||
|
||
**Display pattern:** `po.vessel?.name ?? po.site?.name ?? "—"` everywhere a cost centre name is shown.
|
||
|
||
**URL pre-select:** `/po/new?costCentreRef=v:<id>` or `?costCentreRef=s:<id>`.
|
||
|
||
**Terminology:** Admin pages use the real entity names (Vessel Management, Sites). PO-facing pages use "Cost Centre" for the combined concept. Budget heads are labelled "Accounting Code" (not "Account").
|
||
|
||
### GST Calculation
|
||
|
||
`totalAmount = sum(quantity × unitPrice × (1 + gstRate))` for each line item. The `gstRate` is stored as a decimal on `POLineItem` (e.g., `0.18` = 18%). This applies in Server Actions when computing `totalPrice` per line and the PO `totalAmount`.
|
||
|
||
### Environment Variables
|
||
|
||
```
|
||
NEXTAUTH_SECRET # Required always
|
||
NEXTAUTH_URL # Required always (e.g., http://localhost:3000)
|
||
DATABASE_URL # PostgreSQL connection string
|
||
|
||
# Optional in dev (defaults to local storage + console email):
|
||
R2_ACCOUNT_ID, R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_BUCKET_NAME, R2_PUBLIC_URL
|
||
RESEND_API_KEY, EMAIL_FROM, EMAIL_FROM_NAME
