Requirements

With Docker

• Docker Desktop on macOS or Windows, or Docker Engine on Linux. The template has its own Dockerfile; Compose is not needed.
• An internet connection for the first build, which downloads the Node.js base image and the dependencies.
• Nothing else: the image brings Node.js and Yarn.

Without Docker

• Node.js 22 or newer. The Docker image uses Node.js 24.
• Yarn 4, through Corepack. Run corepack enable once; package.json pins the Yarn version, so yarn picks the right one. If your Node.js has no Corepack, install it first with npm install -g corepack.
• No database and no global packages.

Port

The site listens on port 3030, with Docker and without. Make sure nothing else uses it, or start the site on another port.

• A port is already in use

Accounts and services

None. The site needs no key and no outside service. The contact form works without a back-end: it shows its success message and sends nothing until you connect your own API.
