How to retrieve image url after uploading image to firebase with multer - firebase

Question

I am uploading the image to firebase storage, it is uploaded successfully but I don't know how to get the image url in the firebase.`
const mongoose = require("mongoose");
const express = require("express");
const cors = require("cors");
const cookieparser = require("cookie-parser");
const Multer = require("multer");
const FirebaseStorage = require("multer-firebase-storage");
const dotenv = require("dotenv");
const path = require("path");
//logger
const logger = require("./utils/logger");
//routes
const verifyToken = require("./middleware/authJWT");
const { UserType } = require("./constants/user-types");
const app = express();
dotenv.config();
app.use(cors());
app.use(express.json());
app.use(cookieparser());
app.use("/images", express.static(path.join(__dirname, "/images")));
mongoose
.connect(process.env.MONOGO_URL)
.then(console.log("Connected to MongoDB"))
.catch((err) => console.log(err));
const multer = Multer({
storage: FirebaseStorage({
bucketName: process.env.FIREBASE_BUCKET_NAME,
credentials: {
clientEmail: process.env.FIREBASE_CLIENT_EMAIL,
privateKey: process.env.FIREBASE_PRIVATE_KEY,
projectId: process.env.FIREBASE_PROJECT_ID,
},
}),
});
app.post(
"/api/upload",
[verifyToken(UserType.ADMIN), multer.single("file")],
(req, res) => {
logger.info("uploading imagee.....");
res.status(200).send(req.file);
}
);
app.listen("5001", () => {
console.log("Backend is running.");
});
`
I have uploaded the image using multer, I want image url from the firebase as a response to the endpoint.
