Installation

gamecn ships as three self-contained Node bundles on npm. None require a global install — npx resolves and runs them on demand.

Requirements

• Node 20 or newer. Each CLI has engines.node: ">=20" in its package.json. Older Node versions will fail with a clear error.
• A package manager that exposes npx (npm), bunx (Bun), or pnpm dlx. Any one works.

You don't need to install anything globally. The first npx run downloads the bundle into your machine's cache and reuses it for subsequent runs.

The three CLIs

gamecn

The main CLI. Adds items to an existing project, prints integration instructions, and applies --guided source edits.

npx gamecn --help

create-gamecn

Scaffolds a new project from a template. Reuses the same install pipeline under the hood — templates are just registry items with type: registry:template.

npx create-gamecn my-game --template phaser-endless-runner

gamecn-registry

Authoring CLI for registry maintainers. Validates items, builds a deployable static site, and serves it locally for development. See Authoring if you're shipping your own registry.

npx gamecn-registry --help

Verifying the install

After the first npx run, confirm:

npx gamecn --version
# 0.0.1

Each bundle is ~250-300 KB, runnable in plain Node, with no transitive node_modules to manage.
