const mongoose = require('mongoose');
 
 
const connectDB = (uri) => {
    // console.log("Connecting to DB");
    return mongoose.connect(uri,
    {

        useUnifiedTopology: true
    });
};
 
 
module.exports = connectDB;

8. Now go to app.js and inside await connectDB() pass the uri

 
await connectDB(process.env.MONGODB_URL);
