package.json

package.json

Specifics of npm's package.json handling.

Description

This document is all you need to know about what's required in your package.json file. It must be actual JSON, not just a JavaScript object literal.

A lot of the behavior described in this document is affected by the config settings described in npm-config.

name

The most important things in your package.json are the name and version fields. Those are actually required, and your package won't install without them. The name and version together form an identifier that is assumed to be completely unique. Changes to the package should come along with changes to the version.

The name is what your thing is called.

Some rules:

  • The name must be less than or equal to 214 characters. This includes the scope for scoped packages.
