I have a personal project using node.js, express.js and typescript.

When I run command to build project, it does all right.

But when I try to run it, it crashes, because all imports are "wrong", have a look:

The file dist/index.js has this import:

import app from './core/app';
...

BUT, if I make this change to the import, it runs ok:

import app from './core/app.js';
...

I didn't want to create a script file to do this, how can I solve it?

I'm currently using node version 16.0.

Here is my folder structure

Here is my index.ts

import app from 'src/core/app';

/**
 * Initializing server
 */
app.listen(app.get('port'), () => console.log('Application running -> true'));

Here is my tsconfig.json
