eslint complains about typescript’s path aliasing

To support the tsconfig baseUrl and paths, you need the package eslint-import-resolver-typescript.

1. Make sure to have the basics:

# install the basics
npm i -D @typescript-eslint/parser @typescript-eslint/eslint-plugin

# support tsconfig baseUrl and paths
npm i -D eslint-plugin-import eslint-import-resolver-typescript

2. Then in the eslintrc, here in json:

{
  "settings": {
    "import/resolver": {
      "typescript": {}
    }
  },
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "project": "./tsconfig.json",
    "tsconfigRootDir": "./"
  },
  "plugins": [
    "@typescript-eslint",
    "import"
  ],
  "extends": [
    "plugin:@typescript-eslint/recommended",
    "plugin:@typescript-eslint/recommended-requiring-type-checking"
  ]
}
