eslint-plugin-enforce-es-private

ESLint rules that encourage native ECMAScript private fields and methods (#) instead of TypeScript’s private modifier or underscore-named “private”s.

• ✅ Auto-fixable (with safety checks)
• 🔍 Type-aware (uses type information to catch external references)
• 🧩 Works with Flat Config and legacy .eslintrc

Why?

• Native # privacy is enforced at runtime and by the engine (no accidental access).
• Consistent semantics between JS and TS.
• Clearer intent than naming conventions like _foo.

Installation

npm install eslint-plugin-enforce-es-private --save-dev

Usage (Flat Config)

import eslint from '@eslint/js'
import tsEslint from 'typescript-eslint'
import enforceEsPrivate from 'eslint-plugin-enforce-es-private' // <- import

export default tsEslint.config(
	eslint.configs.recommended,
	...tsEslint.configs.recommended,
	...enforceEsPrivate.configs.recommended, // <- usage recommended config
)
