Typescript + Eslint 对导入的误报 + `declare global`

Question

My `.d.ts. file looks like this:

import type { typesAsObj } from 'entityTypes';

declare global {
  type EntityType = keyof typeof typesAsObj;
}

This produces:

'typesAsObj' is not defined. eslint no-undef

However, this works:

import type { typesAsObj } from 'entityTypes';

type _EntityType = keyof typeof typesAsObj;

declare global {
  type EntityType = _EntityType;
}

Why doesn't the first one work?

Answer 1

Turn off "no-undef": "off"(disallow the use of undeclared variables unless mentioned in /*global */ comments) and to be handled by the typescript compiler itself.

or

Use The "extends": "eslint:recommended" property in a configuration file

 "extends": [
        "eslint:recommended", //<---
        'plugin:jasmine/recommended',
        'plugin:jsdoc/recommended'
    ],
