Modern Nerdplace meetups

Our own meetup platform, replacing meetup.com. Events, sign ups, waitlist, speakers and the history of everything we did before. Runs on modernnerdplace.nl, on our own hardware, for the cost of the electricity.

Next.js 15 with the App Router, React 19, TypeScript, Tailwind, Prisma on PostgreSQL. Node 20.

Running it locally

cp .env.example .env
docker compose up -d postgres
npm ci
npm run prisma:migrate
npm run dev

The site is then on http://localhost:3000. The database runs in Docker on 127.0.0.1:5432; everything else runs on the host, so hot reload works normally.

To check the production image instead, docker compose up -d --build starts the app container and the database together. Do that whenever you touch the Dockerfile.

Useful scripts:

Command	What it does
npm run dev	Dev server
npm run typecheck	tsc --noEmit
npm run build	prisma generate plus next build
npm run prisma:migrate	Create and apply a migration locally
npm run prisma:studio	Browse the database
npm run seed	Seed data
npm run import:meetup	Import the meetup.com history

Where the rest is

• docs/deploy.md how it runs in production: Proxmox LXC, docker compose, Cloudflare tunnel, backup and restore, first organiser.
• docs/avg.md which personal data this stores, and what still needs deciding now that we host it ourselves.
• AGENTS.md conventions, and who owns which files.
• prisma/schema.prisma the data model, and the contract between all the parts.

CI runs the typecheck and the build on every push to main and on every pull request, without a database.
