TypeError: Class constructor File cannot be invoked without 'new'

🐛 bug report

Hello, I noticed that can't run some code built for Node.js target. I caught the following error:

/home/dmitriy/git/jdim/parcel-winston/src/index.ts:13
    new winston.transports.File({ filename: `./error.log`, level: 'error' }),
                           ^
TypeError: Class constructor File cannot be invoked without 'new'
    at Object.<anonymous> (/home/dmitriy/git/jdim/parcel-winston/src/index.ts:13:28)

    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:76:12)
    at internal/main/run_main_module.js:17:47

But if I compile it with tsc it works.

🎛 Configuration (.babelrc, package.json, cli command)

package.json:

{
  "name": "parcel-winston",
  "version": "1.0.0",
  "description": "",
  "source": "src/index.ts",
  "main": "dist/main.js",
  "engines": {
    "node": ">= 14"
  },
  "scripts": {
    "build": "parcel build --no-cache",
    "app": "node ./dist/main.js",
    "build.tsc": "npx tsc --outDir ./dist",
    "app.tsc": "node ./dist/index.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "source-map-support": "^0.5.20",
    "winston": "^3.3.3"
  },
  "devDependencies": {
    "@types/node": "^16.10.9",
    "@typescript-eslint/eslint-plugin": "^5.1.0",
    "@typescript-eslint/parser": "^5.1.0",
    "eslint": "^8.0.1",
    "parcel": "latest",
    "typescript": "^4.4.4"
  }
}

I am using the following scripts:

1. npm run build
2. npm run app

And I see the error.

But I can run it after:

1. npm run build.tsc
2. npm run app.tsc

You'll see no errors, and two log files in the project folder will be created.

🤔 Expected Behavior

Build runs in Node.js without errors.

💁 Possible Solution

According to this answer, you need transpile typescript for modern Node.js target to ES6 and newer.
Modern Node.js versions support ES6 classes, there is no need to transpile them.

Maybe you can read target from tsconfig.json.

💻 Code Sample

Code fragment:

import "source-map-support/register";
import winston from 'winston';

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  defaultMeta: { service: 'user-service' },
  transports: [
    //
    // - Write all logs with level `error` and below to `error.log`
    // - Write all logs with level `info` and below to `combined.log`
    // More about levels: https://github.com/winstonjs/winston#logging
    new winston.transports.File({ filename: `./error.log`, level: 'error' }),
    new winston.transports.File({ filename: `./combined.log` }),
    new winston.transports.Console({
      format: winston.format.simple(),
    }),
  ],
});


export default logger;
