Ralat jenis: connectToMongo bukan fungsi

Kod saya (Index.js)

const connectToMongo = require('./db') connectToMongo();

Kod saya (db.js)

const mongoose = require('mongoose'); const mongoURI = "mongodb://localhost:27017" const connectToMongo = ()=> { mongoose.connect(mongoURI,()=>{ console.log("Connected to mongo successfully") }) } module.export = connectToMongo;

Ada sesiapa boleh tolong?
