Connecting to postgresql from node.js?

Question

PostgreSQL

I am making an example of connecting to a database
const {Client} = require('pg');
const db = new Client({
user:'postgres',
host:'localhost',
password:'12345',
port:5432
})
db.connect()
db.query('SELECT * FROM students',(err, data ) =>{
console.log(err, data);
db.end()
})
I get a bunch of errors, what am I doing wrong, tell me
