Generated declaration for a JavaScript file refers to non-existing module

[bergie-umi]

TypeScript Version: 4.1.2
Search Terms: javascript, javascript declaration, eventemitter (and bunch of others)

Code

import { EventEmitter } from 'events';

export default class Foo extends EventEmitter {}

With tsconfig:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "commonjs",
    "allowJs": true,
    "checkJs": true,
    "outDir": "./dist",
    "declaration": true,
    "strict": false,
    "rootDir": "./src"
  },
  "include": [
    "src/*.js",
    "src/**/*.js"
  ]
}

Expected behavior:

The generated declaration file should contain:

import { EventEmitter } from "events"
export default class Flowtrace extends EventEmitter {}

Actual behavior:

import { EventEmitter } from "node/events"
export default class Flowtrace extends EventEmitter {}

Which produces the following error:

File '/node_modules/@types/node/events.d.ts' is not a module.ts(2306)

For now the fix appears to be to search-and-replace the node/events instances.

Here are some important functions I think. They are in a call hierarchy.

// entry
const declarationTransform = transformNodes(resolver, host, factory, compilerOptions, inputListOrBundle, declarationTransformers, /*allowDtsFiles*/ false);
// for source file js
combinedStatements = factory.createNodeArray(transformDeclarationsForJS(node));
// the direct problem
factory.createStringLiteral(getSpecifierForModuleSymbol(target.parent || target, context)

But why change file to ts could avoid this problem? A little strange. Would keep working on it when have time.
