Legacy .eslintrc.* support

Some projects still use legacy config files:

• .eslintrc.js
• .eslintrc.cjs
• .eslintrc.json

This package provides a dedicated legacy shareable config:

• eslint-config-naming/legacy

Minimal setup

// .eslintrc.cjs
module.exports = {
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint'],
  extends: ['eslint-config-naming/legacy'],
  parserOptions: {
    project: './tsconfig.json',
  },
};

What the legacy config contains

• overrides for **/*.ts and **/*.tsx
• plugins: ["@typescript-eslint"]
• rules: { "@typescript-eslint/naming-convention": ... }

It does not set parser or parserOptions — you own those, because repos vary.

Monorepo example

module.exports = {
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint'],
  extends: ['eslint-config-naming/legacy'],
  parserOptions: {
    project: ['./packages/*/tsconfig.json'],
    tsconfigRootDir: __dirname,
  },
};

Prefer Flat Config when possible

Flat Config is the modern standard and is the primary supported format.
