Package Manager Support

Run without installing

npm install -g create-express-modular
yarn global add create-express-modular
pnpm add -g create-express-modular

How detection works

CEM picks your package manager from these signals (highest priority first):

• Lock file in the project root — pnpm-lock.yaml, yarn.lock, or package-lock.json.
• npm_config_user_agent env var, automatically set when npm / yarn / pnpm invokes a script.
• Defaults to npm.

What changes per PM

• Install commands used during scaffolding
• Generated README.md snippets
• Dockerfile lock file + install command (corepack enabled for pnpm)
• Update notices and inline tips in CLI output

Generated scripts
