does this thread help? https://github.com/microsoft/TypeScript/issues/33079

There is a note about it in the Typescript docs:

Note: node module resolution is the most-commonly used in the TypeScript community and is recommended for most projects. If you are having resolution problems with imports and exports in TypeScript, try setting moduleResolution: "node" to see if it fixes the issue.

That's unfortunately what I have already.

But reading a bit more on https://github.com/microsoft/TypeScript/issues/33079 it seems it might need something in an upcoming relase. If you want to be more compatible with what is out now, I think it would work if there was a cjs exports alternative in the package, I got a few of those kind of dependencies already.

as a general rule, all my projects have support for require and CommonJS but unfortunately I had to drop CommonJS support in local-web-server v5.0.0 due to rollup (used to create the CJS build) not having support for dynamic imports (required to load middleware plugins).

I will look into the Typscript issue.. if it's not too inconvenient, you could use v4.2 until the Typescript people release a fix..

No problem, I'll close this for now.

I got it to work with the latest local-web-server using typescript 4.5 beta.

With this code: (index.ts)

import LocalWebServer from 'local-web-server'

const lws = new LocalWebServer()

and this config: (tsconfig.json)

{
  "compilerOptions": {
    "module": "node12",
  }
}

Running tsc produced this output: (index.js)

"use strict";
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
const local_web_server_1 = __importDefault(require("local-web-server"));
const lws = new local_web_server_1.default();
