Node package.json

This lesson is part of Node.js · All levels

Summary

Package.json is the configuration center of the Node.js project: it contains metadata, dependencies, and executable scripts. This file makes the project easy to share because others just run npm installs. Also, fields like play and type determine how Node loads your project modules.

Key points

Package.json stores project metadata such as name, version, and description
Dependencies contain production packages, devDependencies for tooling development
Field scripts contain commands that can be run through npm run
Npm init -y makes package.json with a default value quickly
