Invalid type declaration when used from ES module

[qwelias]

There are three possible cases:

import * as uWS from 'uWebSockets.js';
console.log(uWS.App); // uWS.App has correct function signature, but is actually `undefined`

import uWS from 'uWebSockets.js/uws.js';
console.log(uWS.App); // uWS.App has type `any`, but is actually a function

import uWS from 'uWebSockets.js';
// Module '"${project_path}/node_modules/uWebSockets.js/index"' has no default export.ts(1192)
console.log(uWS.App); // uWS.App has type `any`, but is actually a function

How to reproduce

NodeJS 14
tsconfig.json:

{
    "compilerOptions": {
        "moduleResolution": "Node",
        "module": "ES2020",
        "target": "ES2020",
        "allowJs": true,
        "checkJs": true,
        "strict": false,
        "noEmit": true
    },
    "include": [
        "**/*.js",
        "**/*.ts"
    ],
    "exclude": [
        "node_modules"
    ]
}

package.json:

{
    "name": "project",
    "version": "0.1.0",
    "type": "module",
    "dependencies": {
        "uWebSockets.js": "github:uNetworking/uWebSockets.js#v18.9.0"
    },
    "devDependencies": {
        "@types/node": "^14.14.5",
        "typescript": "^4.0.5"
    }
}

Put any of the above three code snippets into test.js.
Run node test.js

P.S.

I did try different combinations of moduleResolution, module, and target, but alas.

Fixed by enabling "esModuleInterop": true
