Nodejs: After Import of a module, code in the file is not getting executed - node.js

Question

I am working on few files in nodejs app with typescript
Concerning files are as follows:
some-module.ts
console.log('inside some-module');
export default class Foo {
/*...*/
}
/*execute some imp code*/
Injector.provideClass('Foo', Foo);
console.log('done with some-module');
app.ts
console.log('inside app.ts');
import Foo from './some-module'; // this does not execute console.log! Since Foo class is only referred and not actually used in app.ts file.
class App {
static inject = ['Foo'];
private foo: Foo;
constructor(foo: Foo) {
this.foo = foo;
}
/*...*/
}
Injector.injectClass(App); // This throws error as Foo is not provided in injector.
console.log('Done with app.ts');
Output (console):
$ inside app.ts
$ Done with app.ts
Already tried:
I have tried with const Foo = require('./some-module');, this works but its not the best way to do it in typescript. Since it does not recognize the types in it.
Also -> If if put imported Foo in console.log right after import statement then also it works. Since Foo is now getting used in imported module file.
import Foo from './some-module';
console.log(Foo); // <- After adding this simple log, it works!
Also -> If you do only import import './some-module';
But this way you dont have access to its types.
