Is it possible to find and call a function by its decorator?

What I want to achieve:

I want to develop a core browser library for a given product. There are some parts where function implementations will differ based on a customization ( let’s call them plugin functions ). I want to avoid having to manage these plugin functions inside the library code, I want to manage them in different code bases and only install them during CI/CD so I can include them in the bundle.

The app configuration tells the system which plugin function to choose, let’s assume customer 1 is going for foo and customer 2 for bar. It would be nice if the core library gets a parameter to identify the correct function to be called.

---

What I’ve done so far:

During runtime I had no idea how to call an implementation without an “explicit” if-statement. I think the only way that might work is to use decorators. The configuration will contain a unique name so I might search for a given function.

I started with this decorator every plugin should use

function pluginFunc(name: string) {
  console.log(`plugin func '${name}'`);

  return function (
    target: any,
    propertyKey: string,
    descriptor: PropertyDescriptor
  ) {
    console.log({ name, target, propertyKey, descriptor });
  };
}

export { pluginFunc };

And a custom plugin

import { pluginFunc } from "./pluginFunc";

@pluginFunc("foo")
function pluginOne() {
  console.log("hello from plugin 1");
}

export { pluginOne }

Now I want to test my approach in a simple index.ts file

/* async */ function callPlugin(name: string) {
  // find function by decorator and name and call it
}

callPlugin('foo');

Is it possible to find a function ( without importing it during build time! ) by a decorator pluginFunc and a given name?

If that’s not possible what about the simpler approach to simply call a function by its name ( without importing it ) ?
