ESLint Config Naming

Appearance

Common errors ​

"Unexpected top-level property 'default'" ​

Error message:

ESLint configuration in .eslintrc » eslint-config-naming/legacy is invalid:
- Unexpected top-level property "default".

Cause: You're using an older version of eslint-config-naming (< 1.4.2) with ESLint 8.

Solution: Upgrade to version 1.4.2 or later:

bash
npm install eslint-config-naming@latest

This issue was fixed in version 1.4.2 where the legacy CommonJS export was updated to properly unwrap the configuration object for ESLint 8 compatibility.

"Name must match one of the following formats…" ​

This means the selector matched and the name is in the wrong format.

Fix strategy:

  1. Identify what you’re naming (type? variable? member?)
  2. Check the relevant rule page
  3. Rename or add a scoped override

“Boolean variable must have one of these prefixes…” ​

Rename:

  • enabled → isEnabled
  • active → isActive
