    // ...
    "haku/react",
    "plugin:@typescript-eslint/recommended-type-checked"
  ],

• Add rule to restrict using custom useAppSelector and useAppDispatch for typing

  "@typescript-eslint/no-restricted-imports": [
    "warn",
    {
      name: "react-redux",
      importNames: ["useSelector", "useDispatch"],
      message: "Use typed hooks `useAppDispatch` and `useAppSelector` instead.",
    },
  ],
