libcPresence

Enforces that the libc property is present.

✅ This rule is included in the package-json preset.

This rule requires the libc field in package.json to be present.

Examples

❌ Incorrect

{}

{
  "name": "my-repository"
}

✅ Correct

{
  "libc": "glibc"
}

{
  "libc": ["glibc", "musl"],
  "name": "my-repository"
}

Options

ignorePrivate

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

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 does not need to declare libc compatibility, you can disable this rule. For example, a package that is not platform-specific may not need libc metadata.
