How to exclude referenced Firebase modules in TypeScript Compiler - tsc?

Question

I have config

"exclude": [
"node_modules",
"functions/node_modules",
"typings/browser.d.ts",
"typings/browser"
]

and imports;

import * as admin from "firebase-admin";
import DateUtilities from "../Utilities/DateUtilities";
import CoreUtilities from "../Utilities/CoreUtilities";

and method like;

async GetDocumentData(id: string): Promise<DocumentData> {
let snapshot = await this.GetDocumentSnapshot(id);
return await snapshot.data();
}

DocumentData is a module comes from firebase-admin. Normally if I don't use it in GetDocumentData return value tsc does not try to compile it.

But once I start to use it, it tries to validate all referenced modules like below:

How can I force exclude them?

After some search I found out I had to use tsc --skipLibCheck
