Хочу подключиться к БД. порядок действий:
1. создаю с помощью init package.json
2. устанавливаю pg
Код:
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()
})
Запускаю, получаю ошибку:
