How to add recommended-type-checked

[janat08]

I've added the following, having installed the requisite packages, but the command xo --fix crashes with a cryptic message:
extends: [ 'eslint:recommended', 'plugin:@typescript-eslint/recommended-type-checked', 'plugin:@typescript-eslint/stylistic-type-checked', 'plugin:unicorn/recommended', ], parser: '@typescript-eslint/parser', plugins: ['@typescript-eslint'],

These are all included by default in xo. You do not need any manual step for this. - some of our rules are slightly different than the eslint "recommended" configs but if you really want those configs, xo might not be the right choice of tools for you.

We already support the strictest typescript type aware type checking by default.
