How to access JS file api in angular component.ts file

Question

I have one function in js file under src/server/js/controller.js, and I want to use that API inside component's ts file. I wrote the following code to do same but seems not working

controller.js

const getDomainName= (hostName) => {
    console.log('hostName get controller', hostName); 
}
module.exports = {getDomainName};

flush-component.ts

import {getDomainName} from '../../../../server/controllers/controller.js';
@Injectable({
    providedIn: 'root'
})

export class LaunchUtil {
   //How to call from here
}

Note: I should not put this file under assets folder since it is referring by other JS files.

You should export it like this:

const getDomainName= (hostName) => {
    console.log('hostName get controller', hostName); 
}
export { getDomainName }

And use it anywhere in your application project using import syntax:

import { getDomainName } from '../../../../server/controllers/controller.js';
