What is package.json?

package.json is the manifest file for every Node.js project. It defines the project name, version, scripts, and dependencies. Running npm init creates a minimal one; this generator builds a production-ready template with sensible defaults.

Key Fields

  • name — must be lowercase, no spaces; used as the npm package name if published
  • version — follows semver (MAJOR.MINOR.PATCH)
  • scripts — shortcuts run with npm run <script>; start, build, and test are conventional
  • dependencies — packages required at runtime
  • devDependencies — packages only needed during development or building
  • engines — tells npm/Node which version of Node.js your code requires

Dependency Types

Install runtime deps with npm install <pkg> and dev deps with npm install -D <pkg>. The -D flag writes to devDependencies, keeping your production bundle lean.
