Pelagia Portal

An internal purchase order management system for a maritime vessel-operations company. Digitises the full PO lifecycle — from crew requisition through manager approval, vendor validation, accounts payment, and receipt confirmation — replacing ad-hoc email chains and spreadsheets with a single auditable workflow.

Prerequisites

Tool	Required Version
Node.js	>= 20.11.0 LTS
pnpm	>= 9.0.0
PostgreSQL	>= 16 (local or Docker)

Install pnpm if you don't have it:

npm install -g pnpm

Development Setup

In development mode the app requires only a database and auth secret — Cloudflare R2 and Resend are not needed. File uploads are saved to .dev-uploads/ on your local machine, and emails are printed to the terminal instead of being sent.

1. Install dependencies

pnpm install

2. Configure environment

Copy the example file and fill in the two required values:

cp .env.example .env.local

Minimum .env.local for development:

NEXTAUTH_SECRET=<generate with: openssl rand -base64 32>
NEXTAUTH_URL=http://localhost:3000
DATABASE_URL="postgresql://postgres:postgres@localhost:5432/pelagia_portal"

The R2 and Resend variables are not needed in development and can be left as placeholders.

3. Set up the database

Create the database (if it doesn't exist yet), run migrations, and seed sample data:

pnpm db:migrate     # runs prisma migrate dev
pnpm db:seed        # seeds vessels, accounts, vendors, and demo users

To inspect the database with a GUI:

pnpm db:studio      # opens Prisma Studio at http://localhost:5555

4. Start the dev server

pnpm dev

The app will be available at http://localhost:3000.

Email behaviour in dev: all notification emails are logged to the terminal in place of actual delivery. Look for lines starting with 📧 [DEV EMAIL].

File upload behaviour in dev: uploaded files are written to .dev-uploads/ at the project root. This directory is git-ignored.

Serving in Production

Production requires all environment variables to be set, including Cloudflare R2 credentials and a Resend API key.

1. Configure environment

Set the following variables in your hosting platform (Vercel, etc.) or in .env.local for a self-hosted deploy:

# Auth
NEXTAUTH_SECRET=<strong random secret>
NEXTAUTH_URL=https://your-domain.com

# Database
DATABASE_URL=postgresql://<user>:<password>@<host>:<port>/<db>

# Cloudflare R2
R2_ACCOUNT_ID=<your cloudflare account id>
R2_ACCESS_KEY_ID=<r2 access key>
R2_SECRET_ACCESS_KEY=<r2 secret key>
R2_BUCKET_NAME=pelagia-portal
R2_PUBLIC_URL=https://<bucket>.<account>.r2.cloudflarestorage.com

# Email
RESEND_API_KEY=re_<your key>
EMAIL_FROM=noreply@yourdomain.com
EMAIL_FROM_NAME="Pelagia Portal"

# Report Issue button -> files a Forgejo issue (optional; token needs write:issue)
FORGEJO_URL=https://git.example.com
FORGEJO_REPO=owner/repo
FORGEJO_TOKEN=<forgejo access token>

# Non-prod banner (leave UNSET in production). When set, a fixed
# "INTERNAL DEV / STAGING - NOT PRODUCTION" banner is shown.
# NEXT_PUBLIC_ENV_LABEL="INTERNAL DEV / STAGING - NOT PRODUCTION"

2. Run database migrations

pnpm db:migrate:deploy    # runs prisma migrate deploy (safe for production)

3. Build and start

pnpm build
pnpm start

The app listens on port 3000 by default. Point your reverse proxy (nginx, Caddy, etc.) or hosting platform to that port.

Operations & Automation

This repo carries its own self-hosted issue-to-deploy pipeline (Forgejo + Claude Code on the pms1 server). The full design and runbook live in ../automation/README.md. In short:

• Report Issue button (portal header) files a Forgejo issue tagged portal.
• A watcher triages each issue (Claude posts a requirements breakdown and routes it to claude-queue or interactive), then for queued issues implements a fix and opens a PR.
• Merging a PR and pushing a release tag (vX.Y.Z) triggers a Forgejo Actions runner that deploys to production.
• A staging instance (automation/staging-up.sh, pm2 ppms-staging on port 3200, SSH-tunnel only) runs the latest master against a daily prod-mirror test DB (pelagia_test) for smoke testing before tagging a release.

Operational scripts live under ../automation/: claude-issue-watcher.sh (watcher), refresh-test-db.sh (nightly test-DB refresh), staging-up.sh (staging), and staging-tunnel.cmd (Windows tunnel launcher).
