✅ This rule is included in the package-json logical presets.

This rule checks that the license property is present.

Examples

❌ Incorrect

{}

{
  "name": "my-repository"
}

✅ Correct

{
  "license": "GPL-3.0-only"
}

{
  "license": "GPL-3.0-only",
  "name": "my-repository"
}

Options

ignorePrivate

Whether the property should still be required when the package’s private property is true. Defaults to true.

This option can be useful if the rule is enabled on many package.json files and some files differ in privacy.

When Not To Use It

If your package doesn’t need to specify a license, you can disable this rule. For example, if your package is local-only and is never published online or made open source, licensing may not be relevant for you.
