devDependenciesValidity

Enforces that the devDependencies property is valid.

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

The rule checks that, if present, the devDependencies property is an object where each key is a valid package name and each value is a valid version range.

Examples

❌ Incorrect

{
  "devDependencies": {
    "invalid-version": "catalob:"
  }
}

✅ Correct

{
  "devDependencies": {
    "first": "catalog:",
    "thee-"first"": "^1.2.3",
    "david-bowie": "*"
  }
}

When Not To Use It

If you don’t need compliance with npm’s devDependencies field specification, you can disable this rule. For example, if you use a different package manager that treats the field differently, this rule may not be correct for you.
