npm-init

TLDR

Initialize new project

$ npm init

Initialize with defaults

$ npm init -y

Create with initializer

$ npm init [initializer]

Create React app

$ npm init react-app [my-app]

Create Vite project

$ npm init vite@latest [my-app]

Set default author

$ npm config set init-author-name "[name]"

SYNOPSIS

npm init [options] [initializer]

npm init creates a new package.json file. Without an initializer, it prompts for package details. With an initializer, it runs that package's setup process.
Initializers like "react-app" are shorthand for "create-react-app".

PARAMETERS

-y, --yes

Accept all defaults.

--scope scope

Create scoped package.

-w, --workspace

Create workspace.

initializer

Package to run (create-*).

EXAMPLES

$ # Interactive
npm init
# Answer prompts...

# With defaults
npm init -y

# Using initializer (runs create-react-app)
npm init react-app my-app

# Scoped package
npm init --scope=@myorg

PACKAGE.JSON TEMPLATE

$ {
  "name": "my-package",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": { "test": "echo \"Error: no test\" && exit 1" },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

CAVEATS

-y uses defaults which may need editing. Initializers download packages. Workspace mode for monorepos.
