Create a new React-based project using
$ npm init react-app ./my-react-app
Create a new
esm-compatible package using
$ mkdir my-esm-lib && cd my-esm-lib $ npm init esm --yes
Generate a plain old package.json using legacy init:
$ mkdir my-npm-pkg && cd my-npm-pkg $ git init $ npm init
Generate it without having it ask any questions:
$ npm init -y
npm init <initializer> can be used to set up a new or existing npm package.
initializer in this case is an npm package named
will be installed by
npx, and then have its main bin
executed -- presumably creating or updating
package.json and running any other
The init command is transformed to a corresponding
npx operation as follows:
npm init foo->
npm init @usr/foo->
npm init @usr->
Any additional options will be passed directly to the command, so
npm init foo --hello will map to
npx create-foo --hello.
If the initializer is omitted (by just calling
npm init), init will fall back
to legacy init behavior. It will ask you a bunch of questions, and then write a
package.json for you. It will attempt to make reasonable guesses based on
existing fields, dependencies, and options selected. It is strictly additive, so
it will keep any fields and values that were already set. You can also use
--yes to skip the questionnaire altogether. If you pass
will create a scoped package.
