How to use?

class SetUp implements ServiceWorkerDelegate {

    public applicationConfig(): FirebaseOptions {
        return {
            apiKey: "xxx",
            authDomain: "xxx",
            databaseURL: "xxx",
            projectId: "xxx",
            storageBucket: "xxx",
            messagingSenderId: "xxx",
            appId: "xxx",
            measurementId: "xxx"
        };
    }

let application: FirebaseApplication = new FirebaseApplication(new SetUp());
let firestore: FireStoreWorker = new FireStoreWorker(application);
