import mongoose from 'mongoose';
or
const mongoose = require('mongoose');
const app = express();
mongoose.connect('mongodb://localhost:27017/mongo-tree' , {
useNewUrlParser: true,
useUnifiedTopology: true
});
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
console.log('connected db')
});
app.use('/', (req, res) => {
