💻 Code

//src/logger/logger.mjs
//File is JS mjs file!

const logger = (message) => {
  console.log(message)
}
export default logger;

src/database/database.mts
//File is TS mts file!

import logger from '../logger/logger.mjs';

// tsconfig.json, fragment

{
  "compilerOptions": {
    "target": "ESNext",
    "lib": [
      "esnext"
    ],
    "allowJs": true,
    "esModuleInterop": true,
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "rewriteRelativeImportExtensions": true,
    "resolveJsonModule": true,
  }
}

// "package.json does not have any type overriding because project explicitly uses the correct filename extensions."

🙁 Actual behavior

import mjs in mts file
TS2876: This relative import path is unsafe to rewrite because it looks like a file name, but actually resolves to "../ logger/ logger. mjs"

But works good

• on import .mjs into mjs files.
• on import .mts files into both, mjs and mts.

🙂 Expected behavior

No error emitted. imported filename and extension is correct.
