Imagine a scenario where a class adds itself to another class in the following manner
bar.ts:
import { Foo } from './foo';
export class Bar {}
Foo.prop = Bar;
Now, consider the file foo.ts
export class Foo {
public static prop: any;
}
If we want to utilize this in index.ts
import { Foo } from './foo';
console.log(Foo.prop); // -> undefined
The value returned is undefined. It seems like bar.ts is not being utilized at all (possibly due to tree shaking). To address this, it can be corrected as follows:
import { Foo } from './foo';
import { Bar } from './bar';
new Bar(); // trick!
console.log(Foo.prop); // -> Bar
Is there a method to instruct typescript to include Bar regardless, as the current solution may seem cumbersome.
For reference, here is my tsconfig.json
