Linting with Type Information
Some typescript-eslint rules utilize the awesome power of TypeScript's type checking APIs to provide much deeper insights into your code. To tap into TypeScript's additional powers, there are two small changes you need to make to your config file:

.eslintrc.cjs

/* eslint-env node */
module.exports = {
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/recommended-type-checked', // change
  ],
  plugins: ['@typescript-eslint'],
  parser: '@typescript-eslint/parser',
  parserOptions: {
    project: true, // change
    tsconfigRootDir: __dirname,
  },
  root: true,
};
